20070076255
The present invention relates to an image output apparatus and the like which can print out images photographed with a digital camera, images read by a scanner, image data recorded on a recording medium which has been brought in, image data stored in the apparatus in advance, as well as images obtained through composition and/or editing of the above described images.
In recent years, image output apparatuses (digital photograph printing devices, etc.) have been placed and used in stores and on streets as street terminals (KIOSK terminals). These image output apparatuses read images photographed with a digital camera or the like, image data recorded on a recording medium, and the like, and perform image editing, image composition, printout, etc. (refer to, for example, [Patent Document 1] and [Non-Patent Document 1]).
Image output apparatuses are placed in identification photograph photographing corners near train stations, amusement facilities such as game arcades, and the like. A user brings a recording medium on which image data taken with the user's own digital camera are recorded and loads these images into the image output apparatus, or takes a photograph on site. Then, the user can perform an image editing process and the like as required, and specify output size, the number of outputs, etc. so as to output high-resolution color prints, which the user can take home.
In addition, image display and image selection are performed in the image output apparatus as follows. When a recording medium on which images are recorded is inserted into a media reader, the image output apparatus generally displays a list of images by displaying a plurality of thumbnail images or the like. Then, the user selects an image to be printed out from the image list.
In addition, there is also an image printing system that has a plurality of printers and sequentially assigns items to be printed to these printers.
Patent Document 1: Japanese Patent Application Laid-Open (kokai) No. 2002-46324
Non-Patent Document 1: Dai Nippon Printing Co., Ltd., “Dejitaru-camera no susume”, [online], [searched on Dec. 1, 2002], Internet <URL: http://www.digicamates.com/ susume/index.html>
However, because the conventional image output apparatus accesses a recording medium to read image data each time an image data is displayed or printed out, quick display or print out of the image data is difficult. This is problematic in that, the user (operator, etc.) experiences annoyance and inconvenience when operating the apparatus.
For example, when a list of image data is displayed, multiple images cannot be displayed quickly as in the case of flipping through a photo album. Therefore, waiting time is generated during a page-switching process (processing of operations such as “go to next page” or “back to previous page”), which results in an increase in the overall processing time. Moreover, there is a problem in that since desired image data cannot be selected quickly, the user may stop the use of the image output apparatus, whereby potential print orders may be lost, and ultimately the usage rate and the operation rate of the apparatus decrease.
Furthermore, an image list is displayed in the conventional image output apparatus according to photographing dates (not, however, separated by the dates) or according to the alphabetical order of file names. In addition, the images are displayed in a predetermined, specific sequence or by a predetermined, specific display method, such as the number of displayed images being fixed to 10 images in a 2×5 layout. Thus, the conventional image output apparatus has a problem in that the selection of images to be printed is complicated, and the processing time increases because images that are not to be printed are handled.
For example, the conventional image output apparatus has the following problem. In the case where a large number of images (for example, 100 or more images) are stored in the recording medium, even if the user wishes to process only the images shot during a certain period, the images shot before and after the period may be displayed.
In addition, an image cannot be displayed in the conventional image output apparatus through specification of the photographing date. This is problematic in that the user (user, operator, etc.) experiences annoyance and inconvenience.
In addition, the conventional image output apparatus that has a plurality of printers assigns printing jobs to the printers according to a predetermined sequence (for example, from printer 1 to printer n) every time a printing order is received. Thus, after repeated printing operations, the operation rates of the printers differ greatly from one another, as does the amounts of remaining printing materials. This is problematic in that the timings for replenishing printing materials vary and only a certain printer (for example, printer 1) is used frequently, leading to failure, etc.
Moreover, the conventional image output apparatus has the following problem. When the same image data is printed using different printers, the reproducibility of colors and tones may differ from one another due to differences between individual printers, differences between printing material lots, etc.
In addition, the conventional image output apparatus has a problem in that if printing materials in all of the printers are depleted almost simultaneously, the entire system may stop.
Moreover, the conventional image output apparatus has the following problem. When printed items printed by a plurality of printers are ejected into a plurality of removal openings, the labor of removing the printed items from the plurality of removal openings is placed on the user, and the user's printed items become mixed with those of others.
The present invention was achieved in view of the above-mentioned problems. An object of the present invention. is to provide an image output apparatus and the like that can enhance operability through high-speed display processing and printout processing for image data, enable users to specify display conditions, enhance operability through high-speed display processing and selection processing for image data, perform efficient, high-quality, high-speed image printout, and in addition, reduce maintenance load and workload.
Means for Solving the Problems
In order to achieve the foregoing object, a first invention is an image output apparatus comprising input element for inputting an image data from a recording medium; output element for printing out the image data; temporary storage element for reading non-displayed image data from the recording medium and holding the non-displayed image data in a temporary storage section with holding already-displayed image data; and display element for reading image data from the temporary storage section and displaying the read image data.
The image output apparatus of the first invention reads non-displayed image data from the recording medium and holds the non-displayed image data, as well already-displayed image data, in the temporary storage section. The image output apparatus reads image data from the temporary storage-section and displays the read image data.
The already-displayed image data is an image data that has already been displayed.
The non-displayed image data is an image data that has not yet been displayed and-has been read in advance from the recording medium.
The temporary storage section is a cache memory used as temporary storage element. Static random access memory (SRAM) that has a relatively high data access speed or a hard disk and the like that serves as a large-capacity memory medium can be used as the temporary storage section. The cache memory can be an internal cache that is embedded in a central processing unit (CPU), an external cache that is installed outside of the CPU, etc. In addition, the cache memory can be a hard disk or the-like serving as a large-capacity memory medium.
The temporary storage medium, such as SRAM and the hard disk, has a higher data access speed than a recording medium reading device (media reader).
The recording medium (media) is a recording medium for recording image data; for example, Smart Media, CompactFlash® cards (CF cards), floppy® disks, PC cards, optical disks (CD-ROM, etc.) and the like.
The image output apparatus holds the image data in the temporary storage section or deletes the image data, according to an order of priority and predetermined limitations (predetermined rules, setting data, etc.).
With regards to the order of priority, for example, the image data of the next screen to be displayed may be prioritized. Detailed image data corresponding to a selected simplified image data or a simplified image data near the selected image data may also be prioritized.
The predetermined limitations can be set by specifying the maximum number of image data (the maximum number of already-displayed image data, the maximum number of non-displayed image data, the total sum of these image data, etc.) that can be held in the temporary storage section, the maximum data capacity thereof, and the like.
The image output apparatus of the first invention holds in cache memory image data that had been displayed relatively recently and is very likely to be displayed again. The image data is read from the cache memory rather than the recording medium and displayed. Thus, the image data can be displayed quickly and efficiently.
In addition, the image output apparatus predicts user operations, reads image- data that is very likely to be displayed in the future from the recording medium in advance, and holds the image data in the cache memory. The image data is read from the cache memory rather than the recording medium and displayed. Thus, the image data can be displayed quickly and efficiently.
A second invention is an image output apparatus comprises input element for inputting an image data from a recording medium; temporary storage element for holding in a temporary storage section an image data that has been designated to be printed out; and output element for reading the image data from the temporary storage section and printing out the read image data.
When the image data to be printed out is designated from a displayed list (reduced image data, etc.), the image output apparatus of the second invention reads the image data (detailed image data, etc.) from a cache memory for display or from the recording medium in advance, prior to the printout process. Then, the image data apparatus converts the read data into an image data for printout and holds the image data in a cache memory for printing. When the printout process is performed, the image output apparatus reads the image data from the temporary storage section and prints out the read image data.
In addition, the image output apparatus holds the image data for printout in the temporary storage section or deletes the image data, according to predetermined limitations (predetermined rules, setting data, etc.).
The predetermined limitations can be set by specifying the maximum number of image data (the maximum number of image data for printout) that can be held in the temporary storage section, the maximum data capacity thereof, and the like.
In addition, the image output apparatus can be configured so as to automatically calculate the predetermined limitations based on the capacity of the temporary storing section and the number of printing devices (printers, etc.).
For the image data that has been designated to be printed out, the image output apparatus of the second invention holds the image data for printout in the cache memory in advance, prior to the printout process. The image data are read from the cache memory rather than the recording medium and printed out. Thus, the printout process can be performed quickly and efficiently.
A third invention is an image display method performed by an image output apparatus that prints out image data read out from a recording medium, comprising reading non-displayed image data from the recording medium and holding the non-displayed image data in a temporary storage section with holding already-displayed image data; and reading an image data from the temporary storage section and displaying the read image data.
The third invention is an invention related to the image display method performed by the image output apparatus of the first invention.
A fourth invention is an image display method performed by an image output apparatus that prints out image data read out from a recording medium, comprising holding in a temporary storage section image data that is designated to be printed out; and reading an image data from the temporary storage section and printing out the read image data.
The fourth invention is an invention related to the image output method performed by the image output apparatus of the second invention.
A fifth invention is an image output apparatus comprising input element for inputting an image data from a recording medium; display condition specifying element for displaying selection items for each display condition and specifying the display condition through selection of a selection item; display element for displaying the image data based on the display conditions; and output element for printing out the image data.
The image output apparatus of the fifth invention acquires image data and attached information (photographing date, file name, folder name, etc.) thereof, and displays selection items (date folders, etc.) for each display condition (by date, etc.) The display conditions are specified by selection of the selection items. The image output apparatus displays image data corresponding to the specified display conditions (a list of thumbnail images, etc.), and when an image data is selected, prints out the selected image data.
In addition, the image output apparatus may display the display conditions (dates, etc.) indicated by selection items, at least one representative image data corresponding to the display conditions indicated by the selection items, information (number of image data, etc.) related to the image data corresponding to the display conditions indicated by the selection items, etc., while relating them to the selection items.
In addition, the image output apparatus can sequentially switch the image data pertaining to the selection items and display the image data as the representative image data.
In addition, the image output apparatus may display selection items on a calendar.
Display conditions are the conditions regarding image data that the user wishes to display in a list; for example, date, year, month, week, hour, time zone, etc. of image data creation or image photographing.
Selection items are items used to specify display conditions; for example, date folders displayed by date to specify the date.
The image output apparatus of the fifth invention displays a list of image data based on the display conditions specified by the user (photographing dates, etc.). Thus, the user can easily find desired image data by specifying the display conditions. In addition, the image output apparatus displays only image data meeting the display conditions in the list. Thus, image data not required by the user are not processed, thereby enhancing quick processing and operability.
A sixth invention is an image display method performed by an image output apparatus that prints out image data read out from a recording medium, comprising displaying selection items for each display condition and specifying the display condition through selection of a selection item; and displaying the image data based on the display conditions.
The sixth invention is an invention related to the image output method performed by the image output apparatus of the fifth invention.
A seventh invention is an image output apparatus comprising input element for inputting image data; printing element for printing out image data using a plurality of printing devices; and assigning element for assigning the image data to the plurality of printing devices, where the assigning element preferentially assigns the image data to be printed to the printing device that has printed out the least number of image data.
An eighth invention is an image output apparatus comprising input element for inputting image data; printing element for printing out image data using a plurality of printing devices; and assigning element for assigning the image data to the plurality of printing devices, where the assigning element assigns the same image data to the same printing device.
A ninth invention is an image output apparatus comprising input element for inputting image data; printing element for printing out the image data using a plurality of printing devices; and assigning element for assigning the image data to the plurality of printing devices, where the assigning element assigns a smaller percentage of image data to a certain printing device than to other printing devices.
The image output apparatus of the seventh invention to the ninth invention assigns inputted image data to a plurality of printing devices (printers, etc.), and the respective printing devices perform printout.
The image output apparatus of the seventh invention preferentially assigns the image data to be printed out to the printing device that has printed out the least number of image data.
The image output apparatus of the eighth invention assigns the same image data to the same printing device.
The image output apparatus of the ninth invention assigns a smaller percentage of image data to a certain printing device than to other printing devices.
When order details are received, the image output apparatus of the seventh invention preferentially assigns image data to the printing devices in ascending order of the number of printed out image data. Therefore, the operation rates of printers are almost equal even after repeated printing orders, and the amounts of remaining printing materials do not differ between printers. Thus, situations where the timings for replenishing printing materials vary and certain printers are more frequently used, thereby leading to failure, etc., can be avoided.
When the order details are received, the image output apparatus of the eighth invention assigns the same image data to the same image output apparatus (printer). The same image data are printed by the same printer, and thus, situations where the reproducibility of colors and tones may differ due to differences between individual printers, differences between printing material lots, etc., can be avoided.
When the order details are received, the image output apparatus of the ninth invention assigns a smaller percentage of image data to a certain printing device than to other printing devices. Thus, situations where the printing materials in all of the printers are depleted almost simultaneously, thereby stopping the entire system, can be avoided.

As shown in
Static random access memory (SRAM) with a relatively high data access speed, a hard disk with a large storage capacity, and the like can be used as the cache memory 602.
The image output apparatus 101 (control section 301) receives an instruction to display image data through user operation (Step 501).
When the image data is held in the cache memory 602 (Yes, in Step 502), the image output apparatus 101 reads out the image data from the cache memory 602 to the CPU 601. Then, the image data is transferred to video RAM (VRAM) and displayed on the monitor 307 (Step 503, S61 and S65).
When the image data is not held in the cache memory 602 (No, in Step 502), the image output apparatus 101 reads out the image data from the recording medium 603. Then, the image data is transferred to VRAM and displayed on the monitor 307 (Step 504, S62 and S65).,
The image output apparatus 101 (control section) decides an order of priority in which image data recorded in the recording medium is held in the cache memory (Step 505).
The image output apparatus 101 (control section 301) holds the image data in the cache memory or sweeps out the image data from the cache memory, based on predetermined limitations (cache memory capacity, etc.) and the order of priority of the image data (Step 506, S63 and S64).
The control section 301 temporarily holds the image data 604 in the cache memory 602. Image data 605 held in the cache memory 602 include already-displayed image data (image data that has already been displayed) (S63), non-displayed image data (image data that has been read in advance) (S64), and the like.
Next, an example of the image display process (
The following descriptions are made under the assumption that 10-frame listed images are displayed based on simplified image data (thumbnail image data or reduced image data) within an image data file, and two-frame listed images are displayed based on detailed image data (ordinary image data, actual image data, enlarged image data) within the image data file. In this case, for example, an exchange image file format (EXIF) that holds simplified image data and actual image data in one file can be used as the format type of the image data file.
The image output apparatus 101 displays 10-frame listed images 702 on a monitor screen 701 and holds the images in a cache memory 708 as already-displayed-image data 709 (for the current 10-frame screen) (S71).
In addition, the image output apparatus 101 displays 2-frame listed images 706 on a monitor screen 705 and holds the images in the cache memory 708 as already-displayed image data 710 (for the current 2-frame screen) (S73).
Subsequently, when the same list screen is displayed again, the image output apparatus 101 accesses the cache memory 708 to read out the already-displayed image data 709 or the already-displayed image data 710, and re-displays the 10-frame listed images 702 or the 2-frame listed images 706 on the monitor (S72 and S74).
The user can switch between the 10-frame list screen 701 and the 2-frame list screen 705 by touching a button 704 “2-frame display” or a button 707 “10-frame display” (S75 and S76). In this case, as described above, if the list screen had already been displayed, the image output apparatus 101 reads the already-displayed image data from the cache memory 708 and displays the image data.
The order of priority in which the image data are held in the cache memory can be decided to be the reverse of the order in which the image data were displayed (
As described above, the image output apparatus holds in cache memory the image data that had been displayed relatively recently and are very likely to be displayed again. The image data are read from the cache memory rather than the recording medium and displayed. Thus, the image data can be displayed quickly and efficiently.
After displaying a 10-frame list screen 802 on a monitor screen 801, the image output apparatus 101 reads non-displayed image data 808 (10-frame listed image data for the next and subsequent screens) in advance from a recording medium 806 and holds the image data in a cache memory 807 (S81).
For a selected image-803 (an image selected by the user) and images displayed near the selected image 803 in the 10-frame listed images 802 on the monitor screen 801, the image output apparatus 101 reads 2-frame listed images- 809 corresponding to these images from the recording medium 806 in advance, and holds them in the cache memory 807 (S82).
The image output apparatus 101 may be configured such that when no image is selected by the user, a predetermined image in the listed images (for example, the image in the upper left corner) is processed as the selected image.
Next, if the user touches button 804 “ | >(Next page)”, the image output apparatus 101 accesses the cache memory 807 and reads the non-displayed image data 808 (for 10-frame display for the next screen). Then, the image output apparatus displays a 10-frame listed images 811 of the next page on a monitor screen 810 (S83).
In addition, if the user touches button 805 “2-frame display” on the screen 801, the image output apparatus 101 accesses the cache memory 807 and reads the non-displayed image data 809 (for 2-frame display for the next screen). Then, the image output apparatus 101 displays 2-frame listed images 813 on a monitor screen 812 (S84).
The order of priority in which image data read in advance from the recording medium is held in the cache memory can be decided so that, for example, detailed image data corresponding to the selected simplified image data and the simplified image data displayed in the vicinity thereof, simplified image data corresponding to the selected detailed image data and the detailed image data displayed in the vicinity thereof, or image data for the next or previous screen is prioritized (
The image output apparatus reads the image data that will very likely be displayed from the recording medium and holds the image data in the cache memory by predicting user operations. The image data are read from the cache memory rather than the recording medium and displayed. Thus, the image data can be displayed quickly and efficiently.
Caching performed in advance follows predetermined rules. For example, caching is started from on the image (reference image) designated at the time the list screen is displayed. If no image is designated, the image displayed first is regarded as the reference image. When the simplified display list screen (10-frame, etc.) is displayed, the image data for the detailed display (2-frame, etc.) are also cached at the same time.
The image output apparatus 101 may be configured such that if the caching of the image data within the screen has not been completed when the screen is switched to another, the caching process is canceled. In this case, the canceled caching process can be performed again after the next prior read process is performed.
In addition, if the amount of cached data exceeds the capacity of the cache, data already cached are deleted according to predetermined rules. For example, the oldest image data (the image data cached first) is deleted when the cache has reached maximum capacity.
In addition, in the above embodiment, 10-frame display image data is explained as simplified image and 2-frame display data is explained as detailed image data; however, the numbers of frames to be displayed are not limited to these examples.
Next, an example of an image data printout process is described with reference to
As shown in
SRAM with a relatively high data access speed, a hard disk with a large storage capacity, and the like can be used as the cache memory for display 902 and the cache memory for printing 903.
When an image data is designated to be printed out by user operation, if the detailed image data corresponding to the designated image data is held in the cache memory for display 902, the image output apparatus 101 (control section 301) reads out the detailed image data 906 from the cache memory for display 902, converts the detailed image data into an image data for printout, and holds the converted image data in the cache memory for printing 903 (S91). If the detailed image data corresponding to the designated image data is not stored in the cache memory for display 902 (when a simplified image is used to instruct printout, etc.), the image output apparatus 101 (control section 301) reads out the image data from the recording medium 904, converts the image data into an image data for printout 907, and holds the converted image data in the cache memory for printing 903 (S92).
The foregoing process can be performed in advance before the actual printout process starts.
When performing the printout process, the image output apparatus 101 reads out the image data for printout 907 held in the cache memory for printing 903, and transfers the image data to a printer buffer. The transferred image data is printed out by the printer 311 (S93 and S94).
During the printout process, the image output apparatus 101 deletes image data that has already been printed out from. the cache memory for printing 903. Then, the image output apparatus 101 sequentially reads out the detailed image data that are designated to be printed out but are not held in the cache memory for printing 903, from the cache memory for display 902 (S91) or the recording medium 904 (S92), converts the image data into the image data for printout 907, and holds the converted image data in the cache memory for printing 903. When the actual printout is performed, the image data for printout 907 is read out from the cache memory 903, transferred to the printer buffer, and printed out by the printer 311 (S93 and S94).
As described above, for the image data that is designated to be printed out, the image output apparatus holds in advance the image data for printout in the cache memory before the printout process. Therefore, the image data can be read from the cache memory rather than the recording medium and printed out. Thus, the image data can be printed out quickly and efficiently.
The number of image data held in the cache memory for printing, the size of the cache, etc. may be decided automatically by the image output apparatus according to memory capacity, hard disk capacity, the number of printers, and the like.
As described above, according to the first embodiment of the present invention, the image output apparatus holds in the cash memory already-read image data, image data read in advance, image data for printout, etc. and reads out them from the cache memory rather than the recording medium. Thus, the image output apparatus can quickly perform the display process, the printout process, and the like.
The predetermined limitations, settings, and the like related to the cache memory, for example, the maximum numbers of image data for display and for printout held in the cache memory (the number of already-displayed image data, the number of image data read in advance, the number of image data for printout, the total sum of the these image data, etc.), caching level (mode), the size of image to be cached, the size of cache, and the like, can be set. This setting can be performed by the administrator of the image output apparatus or the like. The image output apparatus holds the information set by the administrator, etc. as setting data in the storage section, and accesses the storage section according to processing details so as to refer the setting data.
In addition, default values indicating standard values may be provided as the setting data, which eliminates the necessity of setting by the administrator, etc. The image output apparatus may be configured such that the entire setting data or a part thereof is stored as separate data (in a separate file) and the like, and the location of the separate data (the separate file) and the like is included in the setting data.
The maximum number of image data to be held in a cache memory can be determined as such. Therefore, even if there are limitations on memory capacity or hard disk capacity of personal computers and the like, hardware resources can be used efficiently and effectively by setting the limitations and upper limits according to the operation environment.
In addition, the maximum number of image data to be read in advance can be set. However, when the number of image data to be read is not limited, the limit can be set to be the same number as the maximum number of the image data held in the cache memory.
In addition, the caching level (mode) can also be set; for example, a quality-priority mode (processing speed is compromised to some extent to cache high-quality image data), a speed-priority mode (process speed is given priority when caching image data), and the like.
In addition, the size of image data to be cached can be also set. For example, when the set size of the image data to be cached is the same as the size of the image data displayed on the screen, the image output apparatus caches the image data as is. When the set size of the image data to be cached is smaller than the size of the image data displayed on the screen, the image output apparatus caches the image data according to the set size and enlarges the cached image data when the image data is displayed. When the set size of the image data to be cached is smaller than the size of the image data displayed on the screen, the image data is enlarged when displayed, and thus, the quality of the displayed image is degraded. However, high speed processing can be realized and the number of cashed image data can be increased.
In addition, the image output apparatus can include each means (
In addition, the image output apparatus can perform guidance through screen display, and additionally, guidance through voice, video, etc.
In addition, the programs which execute the processes shown in
Next, an image output apparatus 102 according to a second embodiment of the present invention is described with reference to
The image output apparatus 102 includes an image data reading and writing means 111, an image editing and compositing means 112, a material database 113, a printing means 114, an order details input means 115, a charging means 116, a display means 117, a display condition specifying means 119, etc.
The image data reading and writing means 111, the image editing and compositing means 112, the material database 113, the printing means 114, the order details input means 115, the charging means 116, and the like shown in
The display means 117 is a display device such as a CRT, a liquid crystal panel, or the like that displays image data. The display means 117 displays image data based on display conditions specified by the display condition specifying means 119.
The display condition specifying means 119 shows selection items for specifying the display conditions. The user specifies the display conditions (date, year, month, week, hour, time zone, etc. of image data creation or photographing) by selecting the selection items.
The outer perspective view, the hardware configuration, and the overall operation of the image output apparatus 102 are the same as those shown in
Next, an operation of the image output apparatus 102 related to an image data acquisition process and a display process (
When an image data is read out from a recording medium to which image data is recorded and a normal output of actual image data and the like is performed, the image output apparatus 102 displays a display condition specification screen, and the user specifies display conditions on the display condition specification screen. The image output apparatus 102 displays a list of image data based on the display conditions specified by the user. Then, the user selects image data from the list of image data and specifies the number of prints, print size, and the like. The list of image data is displayed using reduced images (thumbnail images), etc.
The image output apparatus 102 (control section 301) reads out image data (simplified image data, detailed image data, actual image data, etc.) and image management information accompanying the image data from a recording medium 133 that is inserted into a media insertion opening (Step 1101). The image management information includes the image data photographing date, the image data creation date, the file name, the folder name, and the like.
The image output apparatus 102 displays a display condition specification screen 1201 on the monitor screen (Step 1102). Date folders 1202 are displayed by date (by photographing date or creation date) as selection items for display conditions on the display condition specification screen 1201.
The date folder 1202 is displayed along with a date 1203, a representative image 1204, the number of image data 1205, and the like.
The date 1203 is the date specified by the date folder 1202 as a display condition, for example, “Aug. 1, 2003”.
The representative image 1204 is a part of an image data in the date folder 1202 (for example, the first image data of the day, etc). A reduced image may be displayed, or a plurality of images may be displayed as the representative image 1204.
The number of image data 1205 indicates the number of image data in the date folder 1202, for example, “6”.
The user specifies a display condition (a photographing date) by touching the date folder 1202 on the monitor, on the display condition specification screen 1201 (Step 1103). The user can also select a plurality of date folders 1202.
When the user touches button 1206 “Display” after specifying the display condition by selecting the date folder 1202, the image output apparatus 102 retrieves and extracts image data based on the specified display condition. Then, the image output apparatus 102 displays a list of image data 1222 that meets the display condition on an image data selection screen 1221 (list screen) (Step 1104).
When the user touches button 1224 “Set” on the monitor after selecting image data 1222 and specifying the number of printouts, the image output apparatus 102 prints out the image data. In addition, if the user touches button 1225 “Detailed display” on the monitor after selecting the image data 1222, the image output apparatus 102 displays the detailed image of the image data (not shown).
If the user touches button 1206 “Display” on the monitor, the image output apparatus 102 switches the display condition specification screen 1201 to the image data selection screen 1221 (S1231). If the user touches button 1223 “Date selection” on the monitor, the image output apparatus 102 switches the image data selection screen 1221 to the display condition specification screen 1201 (S1232).
In addition, when specification of the date is unnecessary, the user can display a list of all image data by selecting a folder 1207 “Display all”.
The image output apparatus displays images which are to be displayed in a list, in advance, by date, etc., and allows the user to make selections. In addition to date, the number of image data with the same date, and the selected image (the representative image, etc.) in this date can also be displayed. Furthermore, even after the images are displayed in a list, the user can return to the date selection screen and repeat selection. For example, the user can return to the date selection screen from the list screen and specify a date again.
Therefore, the user can easily select desired images by date. The user can also select and display the desired images intuitively, from past memory, by displaying-images by date.
A date folder 1301 is a selection item by day and is displayed with a date 1305. A week folder 1302 is a selection item by week and is displayed with a week 1306. A month folder 1303 is a selection item by month and is displayed with a month 1307. A year folder 1304 is a selection item by year and is displayed with a year 1308.
In the description of the above-mentioned embodiment, the date folder is used as a selection items for specifying display conditions. However, the date is not the only display condition that can be specified. For example, if the user touches button 1208 “Week”, button 1209 “Month”, or button 1210 “Year” on the monitor, the image output apparatus displays the selection items (the week folder 1302, the month folder 1303, or the year folder 1304) by week, by month, or by year, accordingly. The user can specify a photographing year, a photographing month, a photographing week, etc. by selecting a selection item.
The image output apparatus 102 can display a representative image along with selection items specifying the display conditions.
The user can determine the overview of image data pertaining to the selection items by viewing the representative image. Thus, the user can efficiently find desired images data, leading to the enhancement of the operability of the image output apparatus.
The image output apparatus 102 can display a fixed, predetermined image data (for example, the first image data pertaining to the selection item) as the representative image, or can also sequentially switch the image data pertaining to the selection item and display the image data (like a slide show, etc.).
As shown in
The image output apparatus 102 may be configured in such a manner that the process of switching the representative image 1402 is automatically performed every time a predetermined time passes or when the user touches the representative image 1402 of the date folder 1401 on the monitor. In this case, the image output apparatus 102 may be also configured so that the selection of a date folder is performed when the user touches a part of the date folder other than the representative image, and the process of switching the representative image is performed when the user touches a part corresponding to the representative image.
As described above, the image output apparatus can switch and display images with the same date as such. Thus, the user can determine the content of the image data pertaining to the selection item (folder) more accurately.
Although it is explained in the foregoing embodiment that the selection items specifying display conditions are displayed to be sequentially arranged on the display condition specification screen (
In this case, the user can recognize the display conditions (date, etc.) indicated by selection items instantly from the calendar, as well as display conditions (date, etc.) displayed with the selection items. In other words, the user can intuitively select the desired date or image based on the calendar display.
The image output apparatus may be configured such that an image data list is displayed based on simplified image data (thumbnail image data, reduced image data) within an image data file, and a detailed image is displayed based on detailed image data (ordinary image data, actual image data, enlarged image data, etc.) within the image data file. In this case, for example, the exchange image file format (EXIF) which holds simplified image data and actual image data in one file or the like can be used as the format type of the image data file.
As described above, according to the second embodiment of the present invention, the image output apparatus displays an image data list based on the display conditions (photographing data, etc.) specified by the user. Thus, the user can easily find the desired image data by specifying the display conditions. In addition, the image output apparatus displays only image data meeting the display conditions in the list. Thus, image data not required by the user are not processed, thereby enhancing quick processing and operability.
In addition, the programs which execute the processes shown in

The printed item conveying section 313 conveys printed items to the predetermined printed item removal opening. In addition, the printed item conveying section 313 removes the printed item from the belt conveyer at the removal opening to which the printed item have been conveyed and feeds the printed item to the removal opening.
In addition, the printed item conveying section 313 opens (unlocks) the open and close flap of the removal opening to which the printed items have been conveyed so that the printed item can be removed, and closes (locks) the open and close flaps of the other removal openings so that these openings cannot be used.
The communication control section 314 includes a communication control unit, communication ports, etc., and performs transmission control between the image output apparatus 103.
Next, an operation of the image printing system 100 (image output apparatus 103) is described with reference to
The image output apparatus 103 (control section 301) displays a menu screen showing service details, procedures, guides, and the like and requests that the user make selections (Step 2101).
The image output apparatus 103 acquires image data and displays the image data on the monitor (Step 2102). When inputting image data, the user can select a method, such as reading the image data from a recording media, reading from a scanner, or photographing a subject by an imaging device (digital camera and the like).
The image output apparatus 103 performs processing, editing, compositing, etc. of the image data based on instructions from the user (Step 2103). Processing, editing, and compositing of the image are, for example, compositing input image data together, compositing with a frame image, compositing with existing images and the like, coloring, inputting text, moving, enlarging and reducing, creating postcard data and the like.
The image output apparatus 103 performs a charging process and a receipt issuing process according to the details of the user's order (output mode (photograph print, sticker print, index print, postcard print, etc.), number of prints, and the like) (Step 2104).
The image output apparatus 103 performs image processes such as color correction, resizing, trimming, layout, text and logo composition (Step 2105).
The image output apparatus 103 assigns image data to be printed out to respective image output apparatus 103 (respective printers) (Step 2106), transfers the image data to the respective assigned image output apparatus 103 (each printer), and requests printout of the image data (Step 2107).
Each image output apparatus 103 holds the image data in the memory, the hard disk device., or the like (Step 2108-1, Step 2108-2, Step 2108-3 . . . ), transfers the image data to the printer device which is in an output-ready state, and performs the printout process (Step 2109-1, Step 2109-2, Step 2109-3 . . . ).
Each image output apparatus 103 conveys the printed item (printouts) to the printed item removal opening of the image output apparatus 103 having requested the printing, using a belt conveyer and the like (Step 2110-1, Step 2110-2, Step 2110-3 . . . ).
When continuing the operation of the image printing system 100 (No, in Step 2111), the image output apparatus 103 repeats the processes in Step 2101 to Step 2111.
Through the above-mentioned processes, the image output apparatus 103 assigns image data to be printed out to a plurality of image output apparatus 103 (printers), transfers the corresponding image data to the individual image output apparatus (printers), and requests printout of the image data. The image output apparatus 103 (printers), having received the request for image data printout, prints out the transferred image data and conveys the printed item to the image output apparatus 103 having requested the printing (printed item removal opening).
Next, the processing steps of the image output apparatus 103 related to an assigning process (
The following descriptions are made under the assumption that, in addition to receiving orders for image data printout and performing the printout process itself, the image output apparatus 103-1 (printer 212-1) assigns image data to other image output apparatus 103-2 to 103-4 (printer 212-2 to 212-4), and requests image data printout, as required.
As shown in
First, when the order details 2201 is received, the image output apparatus 103-1 assigns “image A (2 copies) and image C (1 copy)” to the printer 212-1, “image A (1 copy) and image B (1 copy)” to the printer 212-2, “image A (1 copy) and image B (1 copy)” to the printer 212-3, and “image A (1 copy) and image C (1 copy)” to the printer 212-4. The image output apparatus 103-1 to 103-4 (printer 212-1 to 212-4) perform the image data printout process in a printing step 2203.
Next, when the order details 2202 is received, the image output apparatus 103-1 assigns “image E (1 copy)” to the printer 212-1, “image D (1 copy) and image F (1 copy)” to the printer 212-2, “image E (1 copy) and image F (1 copy)” to the printer 212-3, and “image E (1 copy)” to the printer 212-4. The image output apparatus 103-1 to 103-4 (printer 212-1 to 212-4) perform the image data printout process in a printing step 2204.
As described above, when order details are received, the image output apparatus 103-1 preferentially assigns the image data to printing devices in ascending order of the number of printed image data.
Therefore, the operation rates of printers are almost equal even after repeated printing orders, and the amounts of remaining printing materials do not differ between printers. Thus, situations where the timings for replenishing printing materials vary and certain printers (for example, the printer 212-1) are more frequently used, thereby leading to failure, etc., can be avoided.
As shown in
When the order details 2301 is received, the image output apparatus 103-1 assigns “image A (5 copies)” to the printer 212-1, “image B (2 copies)” to the printer 212-2, and “image C (2 copies)” to the printer 212-3. The image output apparatus 103-1 to 103-3 (printer 212-1 to 212-3) perform the image data printout process in a printing step 2302.
As described above, when order details are received, the image output apparatus 103-1 assigns the same image data to the same image output apparatus (printer).
Therefore, the same image data are printed by the same printer, and thus, situations where the reproducibility of colors and tones may differ due to differences between individual printers, differences between printing material lots, etc., can be avoided.
As a variation of
In addition, for example, when printing 20 copies of image G, the printing time is extremely long if all of the copies are assigned to one printer (image output apparatus). In this case, a threshold can be set, and copies exceeding the threshold can be assigned to other printers (image output apparatus). In this case, if the threshold is 15 copies, 15 copies of image G are assigned to the printer 212-1 and 5 copies of image G are assigned to the printer 212-2.
As shown in
When receiving the order details 2601, the image output apparatus 103-1 assigns “image A (3 copies) and image B (2 copies)” to the printer 212-1, “image A (2 copies) and image B (3 copies)” to the printer 212-2, “image A (2 copies) and image B (2 copies,)” to the printer 212-3, and “image A (1 copy) and image B (1 copy)” to the printer 212-4. The image output apparatus 103-1 to 103-4 (printer 212-1 to 212-4) perform the image data printout process in a printing step 2602.
As described above, when order details are received, the image output apparatus 103-1 assigns the image data so that the operation rate of the printer 212-4 is smaller than those of the other printers (for example, 50% of the operation rates of other printers).
Thus, situations where the printing materials in all of the printers are depleted almost simultaneously, thereby stopping the entire system, can be avoided.
The image output apparatus may be configured to equally assign image data to all printers until a certain number of copies are printed, and then assign the image data so that the operation rate of a certain printer becomes smaller than those of the other printers.
In addition, when the printing materials of individual printers will be depleted can be calculated based on the numbers of already-printed copies, and the operation rates of individual printers can be adjusted so that the printing materials of individual printers are depleted with a certain amount of time lag (for example, the time lag between the depletion of printing materials in one printer and that in another printer is two days).
Next, an operation of the image output apparatus 103 related to the printed item conveying process is described with reference to
The following descriptions are made under the assumption that, in addition to receiving orders for image data printout and performing the printout process itself, the image output apparatus 103-1 (printer 212-1) assigns image data to other image output apparatus 1.03-2 to 103-3 (printer 212-2 to 212-3), and requests image data printout, as required (see
If the image output apparatus 103 is the apparatus having requested the printing (apparatus having received the order) (Yes, in Step 2701), the image output apparatus 103 releases the lock 217 of the open and close flap 216 of its own printed item removal opening 205 (Step 2702). If the image output apparatus 103 is not the apparatus having requested the printing (apparatus having received the order) (No, in Step 2701), the image output apparatus 103 conveys the printed items to the image output apparatus (printer) having requested the printing (apparatus having received the order) using the conveyer 205 (Step 2703), and locks the lock 217 of the open and close flap 216 of its own printed item removal opening 205 (Step 2704).
As described above, the image output apparatus 103-1 (printer 212-1) releases the lock 217-1 of the open and close flap 216-1 of its own printed item removal opening 205-1.
On the other hand, the other image output apparatus 103-2 and 103-3 (printer 212-2 and 212-3) convey printed items to the image output apparatus 103-1 (printer 212-1) having requested the printing (apparatus having received the order) using the conveyer 215 and lock the lock 217-2 of the open and close flap 216-2 of the printed item removal opening 205-2 and the lock 217-3 of the open and close flap 216-3 of the printed item removal opening 205-3, respectively.
Therefore, even if image data are assigned to a plurality of printers, the user can remove printed items from one printed item removal opening. Thus, the workload placed on the user can be reduced and mix-ups between the user's printed items and those of others can be prevented.
As described above, according to the third embodiment of the present invention, the image output apparatus assigns image data to be printed out to a plurality of image data output apparatus (printers) using predetermined assigning methods (for example, (1 ) equal assignment of image data, (2) preferential use of printers with large amounts of remaining printing materials, (3) assignment of the same image to the same printer, (4) causing a certain printing device to be used more frequently than other printing devices, (5) any combination of (1 ) to (4), above, and the like). Thus, efficient, high-quality, high-speed image printout can be performed, and in addition, maintenance load can be reduced. In addition, the image output apparatus (printer) receiving a printout request prints out the transferred image data and conveys the printed item to the image output apparatus (printed item removal opening) requesting printout using a belt conveyer, etc. Thus, the workload placed on the user can be reduced and mix-ups between the user's printed items and those of others can be prevented.
In
In addition, the image output apparatus can include each means (
