Description

  The present invention relates to a structure of image data reproduced in a predetermined format, and an image recording apparatus and an image reproduction system using the structure.

  Conventionally, instead of recording image data that has undergone image processing such as rotation and trimming, it is necessary to perform image processing such as rotation and trimming on the original image data and image data before image processing. There is known a method of recording various parameters and program codes in association with each other (see, for example, Patent Document 1).

  According to these methods, information necessary for reproducing image data subjected to image processing can be recorded without being subjected to image processing, and can be recorded in a short time. In addition, according to these methods, since image data that has not been subjected to image processing is input to the image reproduction device, the image reproduction device reproduces the original image data without performing image processing, if necessary. You can also.

  However, if the amount of data required to perform image processing on the image data is large, if the information for performing image processing is recorded together with the image data by the image recording device or transmitted to the image reproducing device, the image processing is performed. The amount of data transferred between the image recording apparatus and the image reproducing apparatus in order to reproduce the image data that has been reproduced increases. For example, in order to combine and reproduce photographic image data with background image data, it is necessary to transfer background image data having a large data amount from the image recording apparatus to the image reproducing apparatus in association with the photographic image data.

JP 2000-285220 A (pages 1, 7 etc.)

  The present invention was created to solve such problems, and reduces the amount of information transferred from the image recording apparatus to the image reproducing apparatus for reproduction in the format set by the image recording apparatus. It is an object of the present invention to provide a possible image recording apparatus, an image data structure, and an image reproduction system for reproducing image data using the image data structure.

  In order to achieve the above object, in the image data structure according to the present invention, the image data and the identifier of the template data that defines the reproduction format of the image data are recorded in a single file different from the template data. By reproducing the image data based on the template data, the image data can be reproduced in a predetermined format. Rather than recording the template data itself in the file in which the image data is recorded, the image file data that can be reproduced in a predetermined format is recorded in the file together with the image data identifier for acquiring the template data. The amount can be reduced.

The identifier may be an identifier for acquiring the template data through a telecommunication line.
The identifier may be a path name of template data.
The identifier may be a UUID (Universal Unique ID) of template data.
By using the UUID as the identifier, even if the address of the template data is changed, the image data can be reproduced using the template data set when the image data is recorded.

  Rotation information that defines a rotation process performed on the image data when the image data is reproduced based on the template data may be recorded in the file. By predefining the rotation processing of the image data according to the object represented by the image data, the image data is rotated based on the template data after being rotated in an appropriate direction according to the reproduction format specified by the template data. It becomes possible to play. For example, when image data created by a digital camera with portrait framing is played back using a playback format defined on the assumption that image data created with landscape framing is inserted, for example, a background image defined by template data And the top and bottom of the object photographed with the digital camera do not match. In such a case, when associating the template data with the image data, after rotating the image data and confirming the state where the rotated image data is inserted into the template data, for example, in which direction the image data is inserted into the template data By recording the rotation information such as how many times it should be rotated, the image data can be used so that the top of the background image matches the top of the object photographed by the digital camera using the rotation information when inserting. Can be inserted into the template data.

  In order to achieve the above object, an image recording apparatus according to the present invention comprises an associating means for associating image data with template data defining a reproduction format of the image data, and the image data and the template associated with the image data. Recording means for recording the identifier in a single file different from the template data. By reproducing the image data based on the template data, the image data can be reproduced in a predetermined format. Rather than recording the template data itself in the file in which the image data is recorded, the image file data that can be reproduced in a predetermined format is recorded in the file together with the image data identifier for acquiring the template data. The amount can be reduced.

The identifier may be an identifier for acquiring the template data through a telecommunication line.
Rotation setting means for setting rotation information defining rotation processing performed on the image data when the image data is reproduced based on the template data, and the recording means stores the rotation information in the file May be recorded.

The image data area 52 is an area where photographic image data is recorded. At the time of reproduction, by reading a pointer from the header area 51, the head address of the image data area 52 can be specified, and thereby photo image data can be read.

FIG. 9 is a sequence chart showing the flow of processing of the digital camera 1, the personal computer 4, and the image reproduction system.
In S105, the personal computer 4 transmits the URL selected by the user to the template server 2 to download the template file.
In S110, an association table is created. After creation, the template file and the created association table are stored in the removable memory 18.

  In S115, the user removes the removable memory 18 and connects it to the digital camera 1. When the removable memory 18 is connected, the digital camera 1 reads the template file and the association table and stores them in the flash memory 19b. As a result, the template file and the association table are transferred to the digital camera 1. The template file and the association table may or may not be deleted from the removable memory 18 after being stored in the flash memory 19b in order to secure a capacity for storing the image file.

  In S120, the digital camera 1 accepts selection of a template file stored in the flash memory 19b. Specifically, for example, the user of the digital camera 1 operates the operation unit 22 to display a menu for selecting a template file, selects a file name of a target template file, and presses a predetermined switch. When a predetermined switch is pressed, the digital camera 1 accepts the template file specified by the file name currently selected as the selected template file, and selects it as the photographic image data created in S125. Associated template files are associated.

In S125, the digital camera 1 creates photographic image data. Specifically, when the user depresses the imaging switch, the digital camera 1 creates photographic image data representing the subject that is currently framed in.
The digital camera 1 may display the photographic image data on the display unit 23 based on the template file after creating the photographic image data. Further, the digital camera 1 receives a rotation instruction for the photographic image data in a state where the photographic image data is displayed based on the template file, rotates the photographic image data in accordance with the received instruction, and converts the rotated photographic image data. You may display based on a template file.
In S130, an image file in which the photographic image data and the URL of the template file are recorded is created. Specifically, the URL associated with the template file selected in S120 is read from the association table recorded in the flash memory 19b, and the read URL and the image in which the photograph image data created in S125 is recorded. Create a file. After creation, the image file is stored in the removable memory 18.
The digital camera 1 may use the template file path recorded in the removable memory as the template file identifier. Specifically, for example, the digital camera 1 may record the template file and the image file in one removable memory, and record the template file path in the header area 51 of the image file.
Further, the digital camera 1 may record the rotation information of the photographic image data in the header area 51 of the image file in accordance with the rotation instruction received when the photographic image data is displayed based on the template file. The rotation information may be in any form as long as the system that reproduces the photographic image data based on the template file can uniquely specify the rotation direction and rotation angle of the photographic image data.

In S135, the user removes the removable memory 18 and connects it to the printer 3. As a result, the image file is transferred to the printer 3.
In S <b> 140, the printer 3 accepts selection of an image file to be printed from image files stored in the removable memory 18.
In S145, the printer 3 transmits the URL of the template file to the template server 2. Specifically, when an image file is selected by the user, the printer 3 reads the selected image file from the removable memory 18. As a result, the image file is input to the printer 3. Next, the URL recorded in the header area 51 of the input image file is read, and the read URL is transmitted to the template server 2.

In S150, the template server 2 transmits a template file uniquely specified by the URL to the printer 3.
Note that when the template file and the image file are recorded in one removable memory, the processing of S145 and S150 is not necessary. In this case, the printer 3 can read the template file from the removable memory 18 with reference to the path of the template file recorded in the header area 51 of the image file to be printed selected in S140.
In S155, the printer 3 prints the input photographic image data based on the received template data. Specifically, the control unit 46 of the printer 3 determines whether the image processing unit 43 and the image processing unit 43 are based on the photographic image data recorded in the image file input by the input unit 41 and the template data recorded in the received template file. The image processing is executed in cooperation, and the created print data is output to the printer engine 44. When print data is output, the printer engine 44 performs printing based on the print data.
When rotation information is recorded in the image file, the printer 3 may rotate the photo image data and print the rotated photo image data based on the template data. Further, when rotation information is recorded in the image file, the printer 3 may allow the user to select whether to use the rotation information effectively or to invalidate the rotation information.

  According to the image file according to the first embodiment of the present invention described above, the photographic image data and the URL for acquiring the template file through the Internet N are recorded in one file. For this reason, the template file that defines the reproduction format of the photo image data can be acquired using the URL recorded in the image file in which the photo image data is recorded. Accordingly, the photographic image data can be printed in a predetermined format.

  Furthermore, according to the image reproduction system of the first embodiment of the present invention, the printer 3 can download the template file corresponding to the URL from the template server 2, so that the photographic image data created by the digital camera 1 is based on the template data. When printing, only the image file needs to be transferred to the printer 3, and there is no need to transfer the template file. Therefore, the amount of data transferred from the digital camera 1 to the printer 3 is small, and even when the capacity of the removable memory 18 is small, the photographic image data can be conveyed from the digital camera 1 to the printer 3.

In this embodiment, the template file and the association table are downloaded by the personal computer 4 and transferred to the digital camera 1 via the removable memory 18, but the digital camera 1 is configured to be connectable to the Internet N, The camera 1 may be downloaded directly from the template server.
In this embodiment, the template file and the image file are associated with each other by the digital camera 1, but the template is used in various information terminals capable of processing image data such as a personal computer, a mobile phone, and a PDA (Personal Digital Assistants). It is possible to associate a file with an image file.

In the first embodiment, the case where reproduction is performed by printing with the printer 3 has been described as an example. However, the image reproduction apparatus may be a personal computer equipped with a display device, and is reproduced by being displayed on the display device. You may do it. Further, the image reproducing apparatus may be a projector, and may be reproduced by projecting onto a screen.
In this embodiment, the data is transferred from the digital camera 1 to the printer 3 by the removable memory 18, but the data may be transferred via a communication path such as the Internet N or a serial cable. In the image reproduction system according to the first embodiment, the amount of data can be reduced, so that the time required for data transfer can be shortened even when the communication path is slow.

(Second embodiment)
The second embodiment is an example in which a UUID (Universally Unique Identifier) of a template file is used as an identifier. In the second embodiment, description of substantially the same parts as in the first embodiment is omitted.
The UUID is a numerical value with a predetermined bit length generated by combining the date and time, the MAC address of the network interface card, a random number, and the like, and is a numerical value that is guaranteed not to overlap. A generation program for generating a UUID is stored in the external storage device 35 of the template server 2 of the second embodiment, and the CPU 31 generates a UUID by executing the generation program.

  FIG. 10 is a schematic diagram showing a management table used by the template server 2 of the second embodiment for managing the template file and the UUID of the template file. The template server 2 generates a UUID to be assigned to the template file, and stores the directory name and file name of the template file and the generated UUID in the same row of the management table. When the template server 2 receives the UUID from the printer 3, the template server 2 transmits a template file uniquely specified by the directory name and file name stored in the same row as the UUID in the management table to the printer 3.

  FIG. 11 is a schematic diagram illustrating an association table according to the second embodiment. In the second embodiment, the personal computer 4 downloads and displays a web page in which the URL of the template file and the UUID of the template file are recorded from the template server 2, and when the user selects the URL, the selected URL is displayed. Transmit to the template server 2. When the template file is received from the template server 2, the personal computer 4 stores the received template file name and the UUID of the template file in the same row of the association table.

FIG. 12 is a schematic diagram showing the structure of the image file of the second embodiment. In the header area 61 of the image file of the second embodiment, a pointer indicating the head address of the image data area 62, the UUID of the template file, and other header information such as the creation date and the image size are recorded.
The photographic image data is not always printed by the printer 3 immediately after it is created, but may be printed after a certain time. In that case, the template file may be moved to another directory in the template server 2 during that time. When the template file URL is used as the identifier, the printer 3 cannot access the template file when the template file is moved to another directory. However, when the UUID is used, the template server 2 manages the template file when moving the template file. If the table is updated, the printer 3 can access the template file set when the photo image data is recorded even if the directory is changed. Therefore, the photographic image data can be printed using the template file set when the photographic image data is recorded.
