a data restoration section 19c allowing the display section 12 to display the information for acquiring the aforementioned image data from the recording medium 9 (which may include other recording sections such as a home server 16b and web server 16a if recorded thereon) of the recording site of the missing image data, or the information for identifying the recording site of the aforementioned image data;
a display section 12 such as a monitor; and
an operation section 13 such as a keyboard or mouse.
The aforementioned means may be arranged on the data management apparatus 10 as hardware. Alternatively, it can be arranged as a management program that allows a computer to function as at least a missing data detection section 19a and data restoration section 19c, wherein this management program is installed on the data management apparatus 10 for execution.
The following describes the image data restoration procedure using a data management apparatus 10. For ease of explanation, the following describes the procedure for creating a recording medium 9 using the recording apparatus 1, and for storing the image data recorded on the recording medium 9 in the data management apparatus 10. The procedure for creating a recording medium 9 using the recording apparatus 1 of the aforementioned configuration will be described with reference to the flow chart diagram of
In Step S101, the medium 8 is loaded on the medium loading section 2 of the recording apparatus 1, the digital camera 7 and camera-equipped cellular mobile telephone 7a are connected to the equipment connection 3, the network connection is connected to the communications network 15, or the recording medium 9 is loaded on the recording medium loading section 4. As described above, a CD-R/RW, DVD±R/RW, DVD-RAM or Blu-ray disc can be used as the recording medium 9. In the present Example, the recording medium 9 serves as an original recording site. Accordingly, to ensure that the image data will not be deleted, it is preferred to use the medium protected against deletion or overwriting or to provide settings so as to protect against deletion or overwriting. In Step S102, the image data recorded on the digital camera 7 or medium 8 or the image data recorded on the web server 16a are read out, and the display section 5 and operation section 6 is used to select the image data to be recorded on the recording medium 9, as required.
In Step S103, the music data to be used as the BGM for reproducing the image data as a slide show with music as required is read from the medium 8, web server 16a, the storage device of the recording apparatus 1. This music data may be selected by a user. Alternatively, it is possible to use the music data preset as a default.
In Step S104, the thumbnail image data obtained by reducing the size of the image data having been read, and the reduced image data such as the screen-nail image data are created, as required. The size of the reduced image data need only be smaller than that of the image data having been inputted. For example, the image data with a reduced number of pixels or the image data with a reduced number of colors and reduced size of the color reproduction area can be used.
In Step S105, as required, the image data having been read is converted into the animation data (data in the format of Video-CD, DVD-Video and HDTV) of the file format that can be read by the image reproduction apparatus such as a DVD player, DVD recorder, HDD recorder or game machine. In this case, no restriction is imposed on the method of creating animation data from the image data. For example, when displaying the still image data like a slide show, the data having no difference corresponding to the time for slide display is added to the still image data, whereby animation data is created. The difference data based on the slide effect set on the slide show program is added to the still image data, whereby animation data is generated.
The image data having been inputted, reduced image data having been created, and animation data having been converted are recorded on the recording medium 9. In this case, it is possible to arrange such a configuration that the data can be recorded on a desired recording medium 9, or data can be recorded only in the properly created recording medium 9. For example, in Step S106, reference is made to the position information (e.g., physical address) stored in the storage device in advance, and a decision is made to see whether or not specific identification information is written in the aforementioned position in advance. The record the data is started only when identification information is written, according to this method.
In this case, the aforementioned identification information is provided to prevent illegal data from being recorded. Accordingly, if the recording site and contents of the identification information are easily made public, identification information itself will be copied, and illegal data recording cannot be prevented. To avoid this problem, at least part of the identification information is preferably written in the area that is inaccessible to the computer OS (i.e., outside the logical address area). To put it more specifically, it is preferably written in the area inside the logical address area of the disk type recording medium.
The following describes the structure of the general recording medium (CD-R) with reference to
There is not restriction to the specific configuration of the identification information. However, as described above, the manufacturer's name is recorded outside the logical address area of the recording medium 9 in advance. Accordingly, the manufacturer's name and the number assigned to the recording medium 9 are used as identification information. This arrangement provides easy and reliable identification of whether or not the recording medium 9 has been created legally.
Various forms of data are recorded on the recording medium 9 containing the identification information. The recording area wherein data can be read is restricted in the image reproduction apparatus. The animation data whose file format has been transformed in Step S107 and associated file (hereinafter referred to as “image reproduction apparatus data group” collectively) are transferred to the predetermined folder preset for writing purpose. After that, the image reproduction apparatus data group is read from the aforementioned folder and is recorded on the logical address area of the recording medium 9. After that, in Step S108, before the computer apparatus data is recorded, the session is once closed in order to identify the area of the data that can be used by the image reproduction apparatus.
In Step S109, the image data, the application such as a slide show program as required, setup file, information file, music data and others (hereinafter referred to as “data group for computer apparatus” collectively) are transferred to the predetermined folder preset for writing purpose. After that, data group for computer apparatus is read from the aforementioned folder and is recorded outside the image reproduction apparatus data group previously recorded on the recording medium 9. A series of writing steps is now complete. The image data may be recorded on any desired form. To reduce the data volume, for example, the data can be recorded after being compressed by a commonly known compression technique.
Various forms of information are recorded on the recording medium 9 created according to the aforementioned procedure, as shown in
Further, the recording structure of the recording medium 9 created according to the aforementioned procedure is as shown in
a plurality of types of image data (image data group) such as image data, thumbnail image data and screen-nail image data inside the “PS_Roll” folder;
an information file (info.txt) containing the management information such as information for specifying the recording site of the recording medium 9, and the identification information of the recording medium 9;
other data groups such as a slide show program inside the “APPL” folder, slide show setup file and automatic start-up file (Autorun.inf).
The image reproduction apparatus data group includes:
a file for associating the image data inside the “VCD” folder as a Video-CD format, DVD-Video format, HDTV format data or the like; and
an application for displaying the image data displayed on the TV screen inside the “SEGMENT” folder, the animation data inside the “MPEGAV” folder and the still image data on the TV screen inside the “DAT” folder.
There is no restriction to the structure for recording the aforementioned image data group. However, to facilitate management when the image data group has been backed up in the data management apparatus 10 or the like, it is preferred to configure the folder according to a predetermined rule and to assign a unique name to the folder. For example, as shown in
Referring to the flow chart diagram of
In Step S201, the recording medium 9 is loaded on the recording medium loading section 14 of the data management apparatus 10. Then in Step S202, the input control section 17 reads an image data group from the recording medium 9. In this case, it may read all the image data recorded on the recording medium 9. Alternatively, if part of the image data recorded on the recording medium 9 is already recorded on the data management apparatus 10, the image data corresponding to the difference may be read. In Step S203, the file is checked to see whether or not the file of the data having been read is damaged. In Step S204, the aforementioned image data group and information file are recorded on the destination recording site of the hard disk 11 or others by the recording control section 18.
There is no restriction to the structure for recording the image data stored according to the aforementioned procedure. However, to facilitate image data management, it is preferred that, if the image data is recorded on the recording medium 9 according to the recording structure shown in
In Step S205, to facilitate image data management, the information described in the information file is registered as a database as required. There is no restriction to the contents of this database. For example, configuration is possible using the album table containing the description of album information, the roll table containing the description of image data group (roll) information, the file table containing the description of image data information, or the exif table containing the description of image data information of the exif format.
The album table is made up of the identification information of recording medium 9 (album ID), the recording medium 9 title (album title), information on the date and time of photographing, the album status indicating the stored image data type (e.g., whether or not the original image data is recorded, or only the reduced image data is recorded), the album type showing whether or not the album is registered as a favorite, and the album link showing whether or not the image data in the album is linked. The roll table is composed of the album ID, image data group (roll) identification information (roll ID), the total image count indicating the quantity of the image data in the roll, and the information on the year/month/day of roll creation. The file table is made up of the roll ID, file name, frame number, file type, file storage site, the rotation information showing whether or not the image is rotated, the file link showing whether or not the file is linked, and the storage status information showing whether or not the original image data is present. The exif table is made up of the roll ID, file name, information on the time and date of photographing, image title and image memorandum.
In the hard disk 11 where the image data has been recorded according to the aforementioned procedure, information on the recorded image data is stored in the information file and database. This arrangement prevents the stored and imaged image data from becoming unclear. For example, as described above, when the user has deleted the image data by an application other than the management program, the information on the deleted image data is not reflected in the information file or database to be generated or updated by the management program. This will result in disagreement between the image data configuration described in the information file (i.e., the configuration of the image data registered by the management program) and the configuration of the actually recorded image data. Thus, the image data registered in the information file but not recorded actually (i.e., missing image data) may be present. In this case, the missing image data is restored according to the procedure shown in the flow chart of
In Step S301, a predetermined program such as an image display program is started. Then in Step S302, the missing data detection section 19a reads the information file recorded on a predetermined position (ROYYMMDDyyy_XXXXXXAABxxx folder in this case) of the hard disk 11 by referring to the description of the aforementioned information file, and specifies the configuration of the image data stored and managed as an electronic album. In Step S303, a step is taken to specify the configuration of the image data actually recorded on a predetermined position (ROYYMMDDyyy_XXXXXXAABxxx folder, THM folder and SCREEN folder in this case) of the hard disk 11. In Step S304, the configuration of image data based on the information file is compared with the configuration of actually recorded image data to check if there is any missing image data that is described in the information file but not actually recorded.
If there is any missing image data, the data restoration section 19c in Step S305 refers to the information file and extracts the identification information of the recording section (recording medium 9 in this case) containing the missing image data, and the information for specifying the image data recording site in the aforementioned recording section.
In Step S306, the data restoration section 19c determines whether or not the aforementioned recording section can be accessed by the data management apparatus 10. In other words, in the case of the recording medium 9, a decision is made to see whether or not the recording medium 9 containing the aforementioned identification information is loaded in the recording medium loading section 14 of the data management apparatus 10. If the recording section is accessible, reference is made to the information for specifying the recording site in Step S309. Then the image data is read from the recording medium 9 and is written into a predetermined recording site inside the hard disk 11. When the image data recorded on the recording section of the recording site is recorded on a compressed form, the compressed image data is read from the recording section. Then the image is decompressed by a commonly known data decompression technique, and the result is written into a predetermined recording site of the hard disk 11.
If the recording section cannot be accessed by the data management apparatus 10, the information for specifying the recording site and the message for prompting the recording site to become accessible are displayed in the display section 12 in Step S307, (wherein the latter message is exemplified by a message for prompting the recording medium 9 containing the aforementioned identification information to be loaded on the recording medium loading section 14 when the recording site is a recording medium 9, and a message for prompting in such a way that, when the recording site is a home server 16b or web server 16a), such a recording site should be connected to the data management apparatus 10 via the network. When the recording section becomes accessible in Step S308, the image data is read and is written into the hard disk 11 in Step S309. Thus, even when image data is missing, a series of the aforementioned processing ensures the aforementioned image data to be restored into the hard disk 11.
In Step S310, the image data is displayed on the display section 12 of the data management apparatus 10. In this case, the image data can be displayed in a desired form. For example, it can be displayed on the image display screen 20, as shown in
The aforementioned tag display column 21 is provided with the button for the information including the identification information of recording medium 9, the date and time information such as the year/month/day of image data photographing and the album title for each of the recording sections (recording medium 9) of the image data recording site. The image data can be selected for each recording medium 9. Further, the tag display column 21 is provided with “album title change” button to change the album title or the like. Further, and the frames wherein the image based on the image data stored and managed for each recording medium is displayed in a tabulated list are arranged in the image display column 22. Various types of buttons for changing the image display format are provided on the lower side. Further, the work menu column 23 is provided with the button for creating and copying the new recording medium using the image displayed on the image display column 22, the button for registering the image data as a favorite item, the button for transmitting the image data via the electronic mail, and the button for printing the image by a printer for household use or by a photo shop.
The button displayed on the tag display column 21 is selected to display the image based on the image data corresponding to a desired recording medium 9. A desired image is selected from among the images displayed on the image display column 22. Then in Step S311, a desired button of the work menu column 23 is pressed and the aforementioned image data is used to create a new recording medium or to organize the data as a new album. This is added to the electronic mail and is transmitted, whereby various forms of processing such as outputting as a print are carried out.
As described above, in the present Example, in the structure wherein the image data recorded on the recording section of the recording site of the recording medium 9 or the like is stored in the recording site of the hard disk 11 of the data management apparatus 10 for each recording medium 9 and is managed therein, the configuration of image data described in the information file is compared with the actually recorded the configuration of image data at the time of starting the image display program. If missing image data is present, it is restored automatically. Accordingly, image data can be stored and managed correctly as an electronic album.
In the aforementioned description, comparison of the data configuration and data restoration are performed at the time of starting the image display program. Processing can be carried out at any timing. Comparison of the data configuration and data restoration can be performed at predetermined time intervals (e.g., every week) or at a predetermined point of time (e.g., 12 o'clock). Alternatively, as shown in
To describe the case-wherein there is no agreement between the configuration of image data based on the information file and the configuration of actually recorded image data, the above description has referred only to the case wherein the image data is missing. Conversely, when the user has added image data using other applications, there may be presence of the image data that is not described in the information file but is recorded actually. In this case, the aforementioned image data may or may not be contained in the image data managed as an electronic album. When the data is to be stored and managed in the same manner as other image data, the information on the aforementioned image data can be acquired by referring to the file name of the aforementioned image data and header information, and the information can be described in the information file and database.
The following describes the management program as a second Example of the present invention with reference to
The above description in the aforementioned first Example refers to the case of specifying the individual image files and restoring the missing image data. When the image data recorded on the recording medium 9 is classified into a plurality of types, the image data may be deleted for each type. Thus, the following describes the procedure of restoring the image data when it has been deleted for each type in the present Example.
In the present Example as well, as shown in
an input control section 17 for reading the image data and identification information from the recording medium 9 loaded on the recording medium loading section 14;
a recording control section 18 for controlling the process of recording the image data on the recording section such as a hard disk 11;
a missing data detection section 19a for determine whether or not the image data recorded on the recording section is configured in a plurality of predetermined types, and for detecting the missing type of image data;
a data restoration section 19c for displaying the information to be displayed on the display section 12, the aforementioned information being the information for specify the recording site for the missing type of image data (recording medium 9 in this case), acquiring the aforementioned type of image data from the recording site or specifying the recording site of the aforementioned type of image data;
a display section 12 such as a monitor; and
an operation section 13 such as a keyboard or mouse.
Referring to the flow chart diagram of
In Step S401, a predetermined program such as an image display program is started. Then in Step S402, reference is made to the file name of the image data recorded in a predetermined location (ROYYMMDDyyy_XXXXXXAABxxx folder, THM folder and SCREEN folder) of the hard disk 11, thereby specifying the image data type (e.g., original image data, thumbnail image data, screen-nail image data) recorded in the hard disk 11. Then in Step S403, a check is made to see whether or not the recorded image data is configured in a plurality of preset types.
If there is a missing type (e.g., the original image data is not recorded when three types of data—original image data, thumbnail image data and screen-nail image data—are necessary in this configuration as shown in
In Step S405, the data restoration section 19c determines whether or not the aforementioned recording section is accessible to the data management apparatus 10. Namely, in the case of the recording medium 9, the data restoration section 19c determines whether or not the recording medium 9 containing the aforementioned identification information is loaded on the recording medium loading section 14 of the data management apparatus 10. If it is accessible, the missing type of image data is read from the recording medium 9 in Step S408, and is recorded in a predetermined recording site of the hard disk 11. If it is not accessible, the information for specifying the recording site of the missing type of image data is displayed on display section 12 in Step S406. When the recording medium 9 is made accessible in Step S407, the image data of that type is read in Step S408 and is written onto the hard disk 11. Thus, even when a specific type of image data is missing, a series of the aforementioned processing ensures the aforementioned type of image data to be restored into the hard disk 11.
In the present Example as well, the image data can be recorded on the recording section in any form. When it is recorded in a compressed form, the compressed image data is read from the recording section. After that, it is decompressed and is written into the predetermined recording site of the hard disk 11.
Then in Step S409, similarly to the case of the first Example, the following items, for example, are indicated as shown in
The button displayed in the tag display column 21 is selected so that the image data corresponding to a desired recording medium 9 is displayed. A desired image is selected from the image displayed on the image display column 22. After that, in Step S410, a desired button of the work menu column 23 is pressed, and the aforementioned image data is used to create a new recording medium or is organized as a new album. It is attached to the electronic mail and is transmitted, or is outputted as a print. It is used for various forms of processing.
In the above description, detection and restoration of the missing type of image data are performed when the image display program is started. Similarly to the case of the first Example, the aforementioned processing can be performed at any timed intervals. It can be performed at predetermined time intervals or a predetermined point of time. For example, as shown in
As described above, in the present Example, the image data is stored and managed in the recording site of the hard disk 11 of the data management apparatus 10 for each recording medium 9 or for each type. In this arrangement, when the image display program is started, a decision step is taken to see whether or not the image data recorded on the recording section is configured as a plurality of predetermined types. If there is a missing type of image data, it is automatically restored. This ensures reliable storage and management of the image data as an electronic album.
The following describes the management program as a third Example of the present invention with reference to
The aforementioned first and second Examples have been described with reference to the case wherein the relevant image file is not present. The image data itself is present, but the contents of the image are modified for some reason in some cases. Namely, the inherent properties of the image data are damaged in some cases. In such cases, the storage and management of the image data cannot be said to have been ensured. Accordingly, the following describes the procedure of restoration in the present Example, wherein the contents of the image data have been changed.
In the present Example, this data management apparatus 10 is arranged as shown in
an input control section 17 for reading the image data or identification information from the recording medium 9 loaded on the recording medium loading section 14;
a recording control section 18 for controlling the step of recording the identification on the recording section of the hard disk 11;
a content change data detection section 19b for detecting the contents-changed image data by checking to see whether or not the contents of the image data have been changed;
a data restoration section 19c for ensuring that the information for identifying the recording site of the contents-changed image data (recording medium 9 in this case) to acquire the image data as a basis of the contents-changed image data from the recording site or the information for identifying the recording site of the image data as a basis of the contents-changed image data are displayed on the display section 12;
a display section 12 such as a monitor; and
an operation section 13 such as a keyboard and mouse.
Referring to the flow chart diagram of
In Step S501, a predetermined program such as an image display program is started. Then in Step S502, the content change data detection section 19b detects the contents-changed image data by taking a decision step of determining if the contents of the image data recorded in the predetermined location (ROYYMMDDyyy_XXXXXXAABxxx folder, THM folder, SCREEN folder in this case) of the hard disk 11 have been changed or not. The aforementioned the contents-changed image data is defined as the image data of the same file name containing the portion different from the image data recorded in the recording medium 9. Such image data is exemplified by the image data having been overwritten subsequent to the step of edition and processing, the image data that contains the missing data constituting the image data or the extra data added thereto, and the image data containing a change in the contents of the subsidiary information described in the header area. There is no restriction to the method of detecting the contents-changed image data. For example, whether image data is overwritten or not can be determined as follows: Comparison is made of the date and time information (time stamp) described in the header area of a series of image data. If the date and time information is relevant (e.g., when arranged according to file name, the date and time of the relevant image data are the same as the date and time of the preceding or succeeding image data, or are intermediate in-between), then the image data is determined as having not been overwritten. If the date and time information are irrelevant (e.g., the date and time of the target image data are not intermediate between the date and time of the preceding succeeding image data), then the image data is determined as having been overwritten. Alternatively, the parity (the sum total of the bits is even or odd) or hash value (a value obtained by computation from the last bit row using a hash function) of the image data as a basis is recorded in the information file in advance. If there is agreement between the parity or hash value of the target image data and the parity or hash value described in the information file, then the image data is determined as not having been overwritten. If there is no agreement, the image data is determined as having been overwritten. In this manner, a decision can be made by comparison between the information recorded in the information file and the properties of the target image data itself.
In Step S503, the contents of the image data have been changed. Then in Step S504, the data restoration section 19c refers to the information file, whereby the information for specifying the recording section containing the image data as a basis of the contents-changed image data or the information for specifying the recording site is extracted from the file name and others.
In Step S505, the data restoration section 19c determines whether or not the aforementioned recording section is accessible to the data management apparatus 10; namely, whether or not, in the case of the recording medium 9, the recording medium 9 containing the aforementioned identification information is loaded on the recording medium loading section 14 of the data management apparatus 10. If it is accessible, the image data is read from the recording medium 9 in Step S508, and is written to a predetermined recording site of the hard disk 11. If it is not accessible, the information for specifying the recording site of the image data is displayed on the display section 12 in Step S506. When the recording medium 9 is made accessible in Step S507, the image data is read in Step S508, and is written on the hard disk 11. Thus, a series of the aforementioned processing ensures the aforementioned type of image data to be restored into the hard disk 11, even when the contents of specific image data have been changed.
In the present Example, the image data recorded in the recording section may be recorded in any form. When it is recorded in a compressed form, the compressed image data is read from the recording section. After that, it is decompressed and is written into the predetermined recording site of the hard disk 11.
Then in Step S509, similarly to the case of the first and second Examples, an image display screen 20 shown in
In the present Example as well, detection or restoration of the contents-changed image data can be processed at any time. It can be processed at predetermined time intervals or a predetermined point of time. It is also possible to arrange such a configuration that the detection or restoration of the contents-changed image data is processed when the user has pressed the data restoration button 23a.
As described above, in the present Example, in a structure wherein image data is stored in the recording site of the hard disk 11 of the data management apparatus 10 for each recording medium 9, and is managed therein, when the image display program is started, a check is made to see whether the contents of the image data recorded in the recording section have been changed or not. If there is any contents-changed image data, it is automatically restored. This arrangement ensures reliable storage and management of the image data as an electronic album.
The aforementioned Example has been described with reference to the case of managing the image data using a management program, without the present invention being restricted thereto. The present invention also applies to the cases of managing other type of data including music data and contents using the management program.
The management method and management program of the present invention provide reliable storage and management of the image data backed up by copying from the recording site (e.g., recording medium) to the recording site (e.g., hard disk).
