The present invention relates to a method, a program and a device for displaying multiple pieces of content information in list form.
Images captured with a digital camera or a camera phone are normally taken into a personal computer (PC) and viewed on a monitor, or processed e.g. saved, edited, deleted or the like. In the image processing like editing, a list of thumbnail images that are reduced images is displayed on the monitor for selecting an image (see, for example, Japanese Patent Laid-open Publication No. 2005-223854).
Various types of content information, besides the images taken with the digital camera or the camera phone, are displayed in list form on the monitor. The content information include both motion and still images, web pages, logos and the like obtained through the internet. On the internet, enormous amounts of content information are constantly been uploaded, and they can be obtained in real time. Therefore, different content information can be displayed in list form every time users access to the internet.
Accompanying information such as keywords can be attached as a tag to each piece of content information. Such tags are shown in list form on the internet. The list of tags is called a tag cloud. In the tag cloud, weight is allocated to each tag based on, for example, search frequency and the weight of the tag is shown with its font size or color.
To emphasize particular images in a list display, images are often laid out with different sizes. There are, for example, a method limiting a region where images can be overlapped (see, for example, Japanese Patent Laid-open Publication No. 2001-188525), a method using a template (see, for example, Japanese Patent Laid-open Publication No. 2005-050051), and a method showing priorities of images (see, for example, Japanese Patent Laid-open Publication No. 2002-354367).
In the invention according to JP-A 2001-188525, however, an image is inserted to an empty region of a displayed image on a monitor, and the invention does not aim to display a plurality of images in list form. In the invention according to JP-A 2005-050051, a plurality of images is displayed only with a predetermined layout, and therefore randomness of the image layout cannot be assured. In the invention according to JP-A 2002-354367, images are laid out regularly in order to show their priories, which results in poor visual features.
It is an object of the present invention to provide a content display method, a content display program and a content display device capable of displaying a list of multiple pieces of content information with different display sizes in an irregular layout.
In order to achieve the above and other objects, a content display method according to the present invention includes a first dividing step, a second dividing step, and a layout step. In the first dividing step, a display area is divided into two divided display areas. In the second dividing step, one of the divided display areas is selected and the selected divided display area is further divided into two divided display areas. This second dividing step is repeated until a predetermined completion condition is satisfied. In the layout step, the multiple pieces of content information are laid out in order to display the corresponding content information in each divided display area.
It is preferable that the completion condition is satisfied when the number of the divided display areas reaches a predetermined number.
It is preferable that a content determining step and a counting step are further included. In the content determining step, content information to be displayed in list form is determined before the first dividing step. In the counting step, the number of the determined content information is counted. The completion condition is preferably satisfied when the number of the divided display areas reaches the number of the determined content information to be displayed.
The completion condition can also be satisfied when dimension of each divided display area becomes smaller than a predetermined value. In the second dividing step, the divided display area to be divided is preferably selected according to a predetermined selection standard. In this case, the selection standard is preferably to select the divided display area having largest dimension.
It is preferable that the first dividing step and the second dividing step respectively includes a direction determining step, an aspect ratio estimating step, a judging step, a position determining step, and a dividing step. In the direction determining step, aspect ratio of an area is calculated and direction to divide the area is determined based on the calculated value. In the aspect ratio estimating step, position to divide within the area is tentatively determined and aspect ratio of each area in case where the area is divided into two at the tentative position is estimated. In the judging step, whether the aspect ratio of each area estimated in the aspect ratio estimating step is in a predetermined range is judged. In the position determining step, it is determined to divide the area at the tentative position when the aspect ratio of each area is in the predetermined range. In the dividing step, the area is divided into two in the direction determined in the direction determining step at the position determined in the position determining step. The dividing position is preferably determined by repeating the aspect ratio estimating step and the judging step until the aspect ratio of each area is judged to be in the predetermined range.
The direction to divide the area is preferably a vertical direction or a horizontal direction.
It is preferable that the content display method further includes a value assigning step, an area ranking step, and an allocating step. In the value assigning step, aspect ratio of each piece of content information is calculated and the calculated value is assigned to the content information. In the area ranking step, the divided display areas are ranked according to a predetermined standard. In the allocating step, aspect ratio of each display area is calculated in the ranked order and one of the content information having closest aspect ratio is allocated to the divided display area.
The divided display areas are preferably ranked according to their dimensions in the area ranking step.
It is preferable that the content display method further includes a content ranking step, an area ranking step, and an allocating step. In the content ranking step, the multiple pieces of content information are ranked according to a predetermined standard. In the area ranking step, the divided display areas are ranked according to a predetermined standard. In the allocating step, the multiple pieces of content information are allocated to the divided display areas in the ranked order.
A value assigning step can be provided before the content ranking step. In the value assigning step, a predetermined value is assigned to each piece of content information. The multiple pieces of content information are ranked according to the assigned predetermined values.
The divided display areas are preferably ranked according to their dimensions in the area ranking step.
A content display program according to the present invention includes a first dividing step, a second dividing step, and a layout step. In the first dividing step, a display area is divided into two divided display areas. In the second dividing step, one of the divided display areas is selected and the selected divided display area is further divided into two divided display areas. This second dividing step is repeated until a predetermined completion condition is satisfied. In the layout step, the multiple pieces of content information are laid out in order to display the corresponding content information in each divided display area.
A content display device according to the present invention includes a first dividing section, an area selecting section, a second dividing section, and a layout section. The first dividing section divides a display area into two divided display areas. The area selecting section selects one of the divided display areas. The second dividing section further divides the selected divided display area into two divided display areas. The area selection by the area selecting section and the division by the second dividing section are repeated until a predetermined completion condition is satisfied. The layout section lays out the multiple pieces of content information to display the corresponding content information in each divided display area.
According to the present invention, the division of the display area is continued until satisfying the predetermined completion condition. Owing to this, multiple pieces of content information having different display sizes can be displayed in list form with irregular layout.
In addition, content information to be displayed in list form is determined, the number of the determined content information is counted, and the completion condition is set to be satisfied when the number of the divided display areas reaches the number of the determined content information to be displayed. Owing to this, the display area with layout that corresponds to the number of the content information to be displayed can be automatically produced.
In addition, the content information having closest aspect ratio is allocated to each divided display area, and this allocation is performed in decreasing order of dimensions of the divided display areas. After the allocation, each piece of content information is displayed in the allocated display area. Owing to this, the larger the display dimension of the content information is, the closer aspect ratio to the original the content information can maintain.
In addition, the multiple pieces of content information are ranked according to the predetermined standard, while the divided display areas are ranked according to their dimensions in decreasing order. The multiple pieces of content information are allocated to the divided display areas in the ranked order, and each piece of content information is displayed in the allocated display area. Owing to this, main content information can be emphasized in the list display.
In addition, the dividing direction is determined based on the aspect ratio of the area to divide, while the dividing position is determined by estimating the aspect ratio of each divided area after the division, and the area is divided in the determined direction at the determined position. Owing to this, the content information is prevented from being too long vertically or horizontally after the division.
The above and other objects and advantages of the present invention will be more apparent from the following detailed description of the preferred embodiments when read in connection with the accompanied drawings, wherein like reference numerals designate like or corresponding parts throughout the several views, and wherein:
[First Embodiment]
In
The digital camera 13 is connected to the PC 12 by wireless LAN or a communication cable complying with, for example, IEEE 1394 or Universal Serial Bus (USB). The digital camera 13 and the PC 12 can communicate data. The recording medium 14 is also capable of communicating data with the PC 12 through a specific driver.
The PC 12 is provided with the monitor 11 for displaying images in list form as well as various operation screens and an operation section 18 constituted of a keyboard 16 and a mouse 17. A user operates the operation section 18 while observing the operation screens on the monitor 11. As shown in
The HDD 22 stores various programs for operating the PC 12, including the content display program, and data. The HDD 22 also stores multiple image data loaded from the digital camera 13, the recording medium 14, and through the internet 15. The CPU 19 reads out the program from the HDD 22 and deploys the program in the RAM 21. The CPU 19 sequentially executes the loaded programs. The CPU 19 also operates each element of the PC 12 according to the operation signals coming from the operation section 18.
The communication I/F 23 mediates the data communication of the PC 12 with the internet 15 or external devices like the digital camera 13. The display controller 24 controls the monitor 11 to display various operation screens and images as the content in list form.
When the content display program is executed by operating the operation section 18, a system shown in
The content determining section 31 determines genre of images to be displayed in list form based on keywords input from the operation section 18. Specifically, related words of the input keywords are produced, and the keywords and the related words are input to the content retrieving section 32. For example, when the keyword “fireworks” is input, related words like “catharine wheel”, “set fireworks” and the like are produced, and the keyword and the related words are input to the content retrieving section 32. When the number of images to be displayed is input from the operation section 18, the content determining section 31 outputs the number to the content retrieving section 32 as well.
Upon receiving the keywords and the related words, the content retrieving section 32 retrieves images having the input keywords and the related words as the accompanying information from the HDD 22. The maximum number of images that the content retrieving section 32 retrieves is predetermined according to the size of the monitor 11. When the number of images to be displayed is designated from the operation section 18, this number is set as the maximum number. When the number of images having the input keywords and the related words as the accompanying information exceeds the maximum number, images are selected based on the accompanying information such as the number of times the image has been viewed (viewed number), registered date, renewed date, image capacity, image dimension and the like.
The counting section 33 counts the number of images retrieved by the content retrieving section 32, and outputs the number to the completion judgment section 34. The completion judgment section 34 judges whether the number of display areas divided by the area dividing section 36 has reached the number of images to be displayed. The division of the display area by the area dividing section 36 is explained later in detail. When judged that the number of divided display areas has not reached the number of images to be displayed, the completion judgment section 34 sends a command to further divide the display area to the area dividing section 36 via the area selecting section 35.
The area dividing section 36 is constituted of a direction determining section 41, an aspect ratio estimating section 42, a judgment section 43, a position determining section 44, and a dividing section 45, and divides the display area selected by the area selecting section 35 into two. The area selecting section 35 selects the display area having largest dimension, and the area dividing section 36 divides the selected display area. When there is only one display area, however, the area selecting section 35 selects this display area, and the area dividing section 36 divides this area into two.
The direction determining section 41 determines the direction of a straight division line for dividing the display area into two. This determination is made in consideration of aspect ratio (AR=vertical length/horizontal length) of the display area before the division. When the display area is vertically long (1≦AR), the direction of the division line is set horizontal. When the display area is horizontally long (AR<1), the direction of the division line is set vertical. Owing to this, the display area is prevented from becoming vertically or horizontally longer after the division. Although the direction of the division line is preliminarily set to the vertical direction or the horizontal direction, the direction can be changed to an oblique direction by operating the operation section 18. In addition, the preliminarily set division line is straight, but the line can be changed to be curbed or jagged by operating the operation section 18.
The aspect ratio estimating section 42 tentatively sets the position of the division line whose direction has been determined by the direction determining section 41. At this time, the position is randomly set. The aspect ratio estimating section 42 estimates the aspect ratio of each divided display area on the assumption that the display area is divided by the division line at the tentatively set position, and outputs the estimated values to the judgment section 43. The judgment section 43 judges whether the estimated values are in the predetermined range, for example, 0.2≦AR≦5. When the estimated values are outside the range, the judgment section 43 let the aspect ratio estimating section 42 continues the operation of tentatively setting the position of the division line until the estimated values meet the range. When the judgment section 43 judges as the estimated values are within the range, the position determining section 44 determines the tentative position set by the aspect ratio estimating section 42 as the position of the division line.
The dividing section 45 divides the display area into two by the division line in the direction determined by the direction determining section 41 and at the position determined by the position determining section 44.
When the completion judgment section 34 judges the number of display areas divided by the area dividing section 36 has reached the number of images to be displayed, the area ranking section 37 ranks the divided display areas according to their dimensions in decreasing order. Meanwhile, the value assigning section 38 calculates the aspect ratio of each image retrieved by the content retrieving section 32 and assigns the calculated value to each image. The allocating section 39 allocates the images to respective divided display areas in ranked order. Specifically, the aspect ratio of each divided display area is calculated, and the image having closest aspect ratio is allocated to each area. In this way, the images are sequentially allocated to the divided display areas in ranked order. Owing to this, the larger the display dimension of the image is, the closer aspect ratio to the original the image can maintain.
The display controller 24 displays images in list form on the monitor 11 by displaying each image in the corresponding display area allocated by the allocating section 39.
Hereinafter, processing steps of the content display device according to a first embodiment is explained. When the content display program is executed, the system constituted of the content determining section 31, the content retrieving section 32, the counting section 33, the completion judgment section 34, the area selecting section 35, the area dividing section 36, the area ranking section 37, the value assigning section 38, and the allocating section 39 is constructed in the CPU 19.
The user inputs desired keywords like, for example, “fireworks” by operating the operation section 18. When the keyword is input, the content determining section 31 produces related words of the input keyword. In this case, for example, the related words “catharine wheel” and “set fireworks” are produced. Then, the keyword and the related words are output to the content retrieving section 32.
As shown in
The completion judgment section 34 sets a completion condition satisfied when the number of divided display areas reaches the number of images counted by the counting section 33. Until this completion condition is satisfied, the completion judgment section 34 sends a command to divide the display area to the area dividing section 36 via the area selecting section 35.
Specifically, as shown in
Here, an example of dividing the display area is explained with a case where an original display area whose dimension (S) is “60” and aspect ratio is “0.6” (AR=6/10) shown in
The area selecting section 35 selects the display area having dimension of “42” and aspect ratio of “0.86” (AR is almost equal to 6/7). Since this display area has the aspect ratio of “0.86” and is horizontally long, the direction determining section 41 sets the direction of the division line vertical. While estimating the aspect ratio after division of each divided display area, the position determining section 44 randomly sets the position of the division line. The dividing section 45 divides the display area into two areas: one has dimension of “30” and aspect ratio of “1.2” (AR=6/5) and the other has dimension of “12” and aspect ratio of “3” (AR=6/2), as shown in
The area selecting section 35 selects the display area having dimension of “30” and aspect ratio of “1.2” (AR=6/5). Since this display area has the aspect ratio of “1.2” and is vertically long, the direction determining section 41 sets the direction of the division line horizontal. While estimating the aspect ratio after division of each divided display area, the position determining section 44 randomly sets the position of the division line. The dividing section 45 divides the display area into two areas: one has dimension of “10” and aspect ratio of “0.4” (AR=2/5) and the other has dimension of “20” and aspect ratio of “0.8” (AR=4/5), as shown in
The area selecting section 35 selects the display area having dimension of “20” and aspect ratio of “0.8” (AR=4/5). Since this display area has the aspect ratio of “0.8” and is horizontally long, the direction determining section 41 sets the direction of the division line vertical. While estimating the aspect ratio after division of each divided display area, the position determining section 44 randomly sets the position of the division line. The dividing section 45 divides the display area into two areas: one has dimension of “8” and aspect ratio of “2” (AR=4/2) and the other has dimension of “12” and aspect ratio of “1.33” (AR is almost equal to 4/3), as shown in
The area selecting section 35 selects the display area having dimension of “18” and aspect ratio of “2” (AR=6/3). Since this display area has the aspect ratio of “2” and is vertically long, the direction determining section 41 sets the direction of the division line horizontal. While estimating the aspect ratio after division of each divided display area, the position determining section 44 randomly sets the position of the division line. The dividing section 45 divides the display area into two areas: one has dimension of “12” and aspect ratio of “1.33” (AR is almost equal to 4/3) and the other has dimension of “6” and aspect ratio of “0.67” (AR is almost equal to 2/3), as shown in
When it is judged that the completion condition is satisfied, the area ranking section 37 ranks the divided display areas according to their dimensions in decreasing order. As shown in
The display controller 24 displays images in list form by displaying each image in the allocated display area.
According to the first embodiment, the larger the display dimension of the image is, the closer aspect ratio to the original the image can maintain. It is also possible that the display dimensions are varied depending on the importance of the images in a content display device according to a second embodiment explained hereinafter.
[Second Embodiment]
When the content display program is executed by operating the operation section 18, a system shown in
The value assigning section 51 reads out the viewed number of each image retrieved by the content retrieving section 32 and assigns the viewed number as its value to each image. The content ranking section 52 ranks the images in decreasing order according to their values. The allocating section 53 allocates the images ranked by the content ranking section 52 to respective display areas in ranked order ranked by the area ranking section 37. Specifically, the image ranked first is allocated to the display area ranked first, the image ranked second is allocated to the display area ranked second, and so on. For this configuration, the more the image is viewed, the larger the display dimension of the image becomes.
The display controller 24 displays images in list form by displaying a screen in which each image is allocated to the corresponding display area. Note that the same components as the first embodiment are assigned with the same numerals, and detailed explanations thereof are omitted.
Hereinafter, processing steps of the content display device according to the second embodiment is explained. When the content display program is executed, the system constituted of the content determining section 31, the content retrieving section 32, the counting section 33, the completion judgment section 34, the area selecting section 35, the area dividing section 36, the area ranking section 37, the value assigning section 51, the content ranking section 52, and the allocating section 53 is constructed in the CPU 19.
When keywords are input by operating the operation section 18, the content determining section 31 produces related words of the keywords, and the keywords and the related words are output to the content retrieving section 32.
As shown in
When the ranking of the display areas by the area ranking section 37 and the ranking of the images by the content ranking section 52 are completed, the allocating section 53 allocates each image to the corresponding display area in ranked order.
The display controller 24 displays images in list form on the monitor 11 by displaying each image in the allocated display area.
In the above embodiments, the images retrieved from the HDD 22 are displayed in list form. However, it is also possible to display a list of images obtained from the digital camera 13, the recording medium 14, the internet 15, and the like via the communication I/F 23.
In the above embodiments, although the maximum number of images to be displayed in list form is preliminarily determined, the number is not necessarily limited.
In the above embodiments, the completion condition is satisfied when the number of divided display areas reaches the predetermined number. However, it is also possible that the completion condition is satisfied when, for example, the display dimension of each divided display area becomes smaller than a predetermined value.
In the above embodiments, although the area selecting section 35 selects the display area having largest display area, the area selecting section 35 may selects a display area randomly or according to other standards.
In the above embodiments, although the direction of the division line is determined in consideration of the aspect ratio of the display area, the direction may be determined randomly or according to other standards.
In the above embodiments, although the position of the division line is tentatively determined in a random manner, the position may be determined according to other standards.
In the above embodiments, although the divided display areas are ranked according to their dimensions in decreasing order, the divided display areas may be ranked according to their dimensions in ascending order, or according to other standards.
In the above embodiments, the list of images is displayed with no spaces provided between the adjacent images. However, it is possible to provide a predetermined width of margin between the images, to provide each image with a frame, to display the image with its corner rounded off, or the like.
In the second embodiment, the value assigning section 51 assigns the viewed number as the value to each image. However, it is also possible to assign value based on other accompanying information such as the registered date, renewed date, image capacity, image dimension, a combination thereof, and the like. The accompanying information is not limited as long as it is unique information to each image.
Various changes and modifications are possible in the present invention and may be understood to be within the present invention.
