Description

The present invention relates to an image output technique.

Conventionally, H. There is a file format that is internationally standardized by ISO / IEC26008-12 called HEIF (High Efficiency Image File Format) that stores still images encoded by 265 (HEVC). In HEIF, it is possible to store not only a single still image but also a plurality of still images or image sequences (burst-shot continuous shot images, etc.) in one file. It also defines a normative structure that includes metadata, how to associate metadata with images, and the composition of specific formats of metadata. This makes it possible to describe in the metadata one image representation composed of a plurality of still images, which is called a derived image.

Further, conventionally, in an information processing apparatus capable of reading an HEIF file and displaying an image, the following two processing methods are implemented in order to print the image stored in the HEIF file with a printer.

The first method is to decode the encoded data of the image to be printed, create print data that can be interpreted by the printer from the decoded data, and send it to the printer. This method requires the information processing device to have drivers and application software corresponding to the printer model.

The second method is to read the HEIF file and H.I. This is a method of transmitting the HEIF file as it is to a printer capable of decoding 265. For example, a HEIF file is transmitted using a transfer protocol called FTP (File Transfer Protocol) or PTP (Picture Transfer Protocol). However, since the HEIF file is directly transmitted to the printer, it is necessary to separately transmit the information specifying the image to be printed in the HEIF file to the printer. In addition, since the non-printed image in the HEIF file is also transmitted, useless data is transmitted.

Patent Document 1 describes a technique for creating a small-sized print file by deleting a part or all of non-printable objects contained in a file described in a format that can be interpreted by a printer and sending it to the printer. It has been disclosed.

When the HEIF file 300 is the image file 103 of FIG. 1, the item ID of any of the captured images (image items) of the captured images 104 to 107 is specified in this box.

Reference number 305 indicates an InformationBox ('iloc'), and this box contains information indicating a storage location of data of each item such as a captured image in the HEIF file 300. The data format of the'iloc'box in this embodiment is shown in FIG.

Information 701 to 705 in FIG. 7 is information for specifying a storage location of item data in the HEIF file 300. The item_count indicated by the information 706 is the number of items. For the item corresponding to the item_ID indicated by the information 701, the information 702 means that the location of the item's data is represented by a byte offset from the beginning of the HEIF file 300.

As described above, the image item and the coded data in'mdat'are associated with each other by the information specifying the position in the file where the data of the item of'iloc' indicated by the reference number 305 exists.

Next, the operation of the photographing apparatus 101 will be described according to the flowchart of FIG. In step S802, the CPU 202 gives an instruction to select a photographed image (image item) to be printed by the printing device 102 and a print instruction among a plurality of captured images included in the image file (first image file) which is a HEIF file. accept.

For example, the CPU 202 decodes each captured image included in the image file and displays it in a list on the display screen of the display unit 207, and displays a print instruction button for instructing printing on the display screen of the display unit 207. Display above.

When the user touches the captured image to be printed by the printing device 102 among the plurality of captured images displayed on the display screen of the display unit 207, the selection instruction of the captured image is input to the CPU 202. Then, when the user touches the print instruction button after selecting the captured image to be printed by the printing device 102, the print instruction is input to the CPU 202.

The process in step S802 is, for example, a process performed by the CPU 202 executing the image display application software. When the print instruction is input to the CPU 202, the process proceeds to step S803.

The processes of steps S803 to S806 are, for example, processes performed by the CPU 202 executing the print application software corresponding to the HEIF file. In step S803, the CPU 202 generates a print HEIF file that duplicates the first image file as the second image file.

In step S804, the CPU 202 sets the item ID of one of the captured images (image items) of the captured images (captured images to be printed by the printing device 102) corresponding to the selection instruction received in step S802 in the second image file. Set to item_ID of'print'.

In step S805, the CPU 202 causes the second image so that the printing device 102 does not print a captured image other than the captured image corresponding to the selection instruction received in step S802 among the captured images included in the second image file. Process the file. The details of the process in step S805 will be described later.

In step S806, the CPU 202 controls the communication control unit 209, and outputs the second image file processed in step S805 and the printing instruction of the captured image included in the second image file to the printing device 102. And send.

Next, the details of the process in step S805 will be described with reference to the flowchart of FIG. In step S902, the CPU 202 determines the captured image (image item not to be printed) other than the captured image (image item to be printed) corresponding to the selection instruction received in step S802 among the captured images included in the second image file. ) Are all selected as selected image items. As a result of this determination, if all of the image items not to be printed are selected as the selected image items, the process according to the flowchart of FIG. 9 is completed, and the process proceeds to step S806. On the other hand, if there are still image items that have not been selected as selected image items among the image items that are not to be printed, the process proceeds to step S903.

In step S903, the CPU 202 selects one of the image items not yet selected as the selected image item among the image items not to be printed as the selected image item. Then, the CPU 202 determines whether the selected image item is an image item constituting the image item to be printed. For example, the CPU 202 checks the information in the'iref'box in the second image file to see if the selected image item has an association that constitutes the image item to be printed. Then, if the CPU 202 has "association such that the selected image item constitutes an image item to be printed", the process proceeds to step S902, and if not, the process proceeds to step S904.

In step S904, the CPU 202 rewrites the item_type of the'infe'entry in the item information ('iniinf') of the selected image item to'none'in the second image file. 'None' is a value indicating that the image item is invalid and the output of the image item is impossible. The method for preventing the printing device 102 from printing the selected image item is not limited to the above method. For example, "a 32-bit value such that the reader of the HEIF file on the printing device 102 side cannot recognize the type of the image item" may be set in the item_type of the'infe'entry of the selected image item.

In step S905, the CPU 202 determines whether or not it is necessary to reduce the data size of the transmission data transmitted by the photographing device 101 to the printing device 102. There are various methods for this judgment, and the method is not limited to a specific method.

For example, the CPU 202 effectively reduces the data size of the first image file, the connection form and data transfer method between the photographing device 101 and the printing device 102, and the data size of the transmission data transmitted by the photographing device 101 to the printing device 102. The above judgment is made based on the user setting of whether or not to do so.

For example, when the data size of the first image file is larger than the threshold value and the photographing device 101 and the printing device 102 are connected to each other via the IP network, the CPU 202 "needs to reduce the data size of the transmission data". There is. "

As a result of such a determination, if it is necessary to reduce the data size of the transmission data, the process proceeds to step S906, and if it is not necessary to reduce the data size of the transmission data, the process proceeds to step S902. ..

In step S906, the CPU 202 determines whether or not the second image file contains the coded data of the selected image item. Most image items have coded data, such as HEVC image items whose image_type is'hvc1', but there are cases where image items, such as derivative image items, do not have coded data.

As a result of such a determination, if the second image file contains the coded data of the selected image item, the process proceeds to step S907, and the second image file contains the coded data of the selected image item. If not, the process proceeds to step S902.

In step S907, the CPU 202 deletes the coded data of the selected image item from the'mdat'of the second image file. Further, the CPU 202 sets the values of the information 704 (extent_offset) and the information 705 (extent_length) of the coded data to 0 in the'iloc'of the second image file.

When the storage position of other coded data in the HEIF file is changed by such processing on the second image file, extend_offset (information 704) is updated to the value of the correct offset position.

[Second Embodiment]
In each of the following embodiments including the present embodiment, the differences from the first embodiment will be described, and unless otherwise specified below, the same as the first embodiment. In this embodiment, the process in step S805 is different from that of the first embodiment. The process of step S805 according to the present embodiment will be described with reference to the flowchart of FIG.

In step S1002, as in step S902 above, the CPU 202 is a captured image other than the captured image (image item to be printed) corresponding to the selection instruction received in step S802 among the captured images included in the second image file. Judges whether or not all of (image items not to be printed) are selected as selected image items. As a result of this determination, if all of the image items not to be printed are selected as the selected image items, the process according to the flowchart of FIG. 10 is completed, and the process proceeds to step S806. On the other hand, if there are still image items that have not been selected as selected image items among the image items that are not to be printed, the process proceeds to step S1003.

In step S1003, similarly to step S903 described above, the CPU 202 selects one of the image items not yet selected as the selected image item among the image items not to be printed as the selected image item. Then, the CPU 202 determines whether the selected image item is an image item constituting the image item to be printed. Then, if the CPU 202 has "association such that the selected image item constitutes an image item to be printed", the process proceeds to step S1002, and if not, the process proceeds to step S1004.

In step S1004, the CPU 202 deletes the'infe'entry data of the selected image item from the'iinf'box of the second image file. Taking FIG. 5 as an example, the entry of the selected image item is deleted from the data array of ItemInfoEntry with the reference number 502, and the entry_count of the reference number 501 is subtracted by 1. By deleting the'infe'entry data of the selected image item, the definition of the item ID of the selected image item is lost, so that it is substantially equivalent to deleting the selected image item from the second image file. Further, unnecessary metadata such as the attribute information included in the'iprp'corresponding to the deleted selected image item and the association information with the attribute information may be deleted.

In step S1005, similarly to step S905 described above, the CPU 202 determines whether or not it is necessary to reduce the data size of the transmission data transmitted by the photographing device 101 to the printing device 102. As a result of such a determination, if it is necessary to reduce the data size of the transmission data, the process proceeds to step S1006, and if it is not necessary to reduce the data size of the transmission data, the process proceeds to step S1008. ..

In step S1006, similarly to step S906 described above, the CPU 202 determines whether or not the second image file contains the coded data of the selected image item. As a result of such a determination, if the second image file contains the coded data of the selected image item, the process proceeds to step S1007, and the second image file contains the coded data of the selected image item. If not, the process proceeds to step S1008.

In step S1007, the CPU 202 deletes the coded data of the selected image item from the'mdat'of the second image file. In step S1008, the CPU 202 changes the contents of the'iloc'of the second image file. First, the CPU 202 deletes the entry data of the selected image item from the second image file. Taking FIG. 7 as an example, the CPU 202 deletes the entry data (informations 701 to 705) of the selected image item and subtracts 1 from the item_count indicated by the information 706. Further, the CPU 202 calculates and sets each entry_offset (information 704) to be the value of the correct offset position for the entries of other items in'iloc'.

[Third Embodiment]
In the present embodiment, a template file having a model internal structure for generating a second image file is created in advance and stored in the storage media unit 210 or ROM 204. Then, the CPU 202 creates the template file generated by extracting the image item to be printed and its related data from the first image file and inserting the image item into the corresponding place in the template file as the second image file. .. The template file may have the internal structure shown in FIGS. 3 to 7.

The image items to be extracted and their related data are the data corresponding to the image items included in'iinf'(306),'iref' (307), and'iprp' (308) in FIG. 3, and'mdat. '(311) is the coded data. Note that'ftyp'(301) and'hdlr'(302) extract information from the first image file and set it in the template file. Further, the content of ‘iloc’ (305) is calculated and created according to the size of the data to be inserted. As a matter of course, the non-printable image items included in the first image file are not extracted. That is, a second image file containing only the image item to be printed is created and transmitted.

As described above, according to each of the above embodiments, when the printing apparatus 102 receives the second image file, the printing apparatus 102 decodes the encoded data of only the image item that can be identified as an image item by item_type in the second image file. Will be printed. As a result, not all the captured images included in the image file are printed, but the captured image selected by the user is printed, and the captured image not selected by the user is not printed.

Further, according to each of the above embodiments, by reducing the data size of the transmission data transmitted from the photographing device 101 to the printing device 102, the transmission traffic to the printing device 102 and the amount of processing data in the printing device 102 can be reduced. It is expected that the printing process will be more efficient.

HEIF files often include images and their thumbnail images within the HEIF file. In addition, HEIF makes it possible to create an image sequence (Image Sequence) in which a plurality of images that are continuously connected in time are stored in one file. HEIF also makes it possible to store various images in one file and create a file called an image collection like an image album. Although not limited to HEIF, in an image file in a file format capable of storing a plurality of images, only one or more images may be selected for output such as printing or display. In such a case, according to each of the above embodiments, it is not necessary to separately transmit the information specifying the image to be output in the image file as in the prior art, and the image to be printed is included and the image to be printed includes the image to be printed. Send an image file that does not contain any images. Further, according to each of the above embodiments, it is possible to eliminate waste such as transmitting an image that is not a print target.

[Fourth Embodiment]
In each of the above embodiments, the captured image to be printed by the printing device 102 is selected from the plurality of captured images included in the image file according to the user operation, but the selection is performed without the user operation. It may be done, and the method for the selection is not limited to a specific method. For example, when the image file contains the photographed images corresponding to the photographed times T1, T2, T3, T4, ..., The CPU 202 "prints" the photographed images at the photographed times T1, T3, T5, ... It may be selected as "a photographed image to be printed on 102". That is, the CPU 202 may select two or more captured images from a plurality of captured images included in the image file by an appropriate sampling method.

Further, in each of the above embodiments, the "photographed image to be printed by the printing device 102" is selected from the plurality of captured images included in the image file, but the "photographed image not to be printed by the printing device 102" is selected. You may try to do it. In this case, the selected captured image (captured image not to be printed by the printing device 102) is used as the selected image item, and the processing according to the flowchart of FIG. 9 and the processing according to the flowchart of FIG. 10 are performed.

Further, in each of the above embodiments, the case of printing the captured image included in the image file has been described. However, the captured image included in the image file is not limited to printing, and may be targeted for various outputs such as transmission to an external device, display on a display device, and storage in a storage device.

Further, in each of the above embodiments, the captured image is encoded and stored in the image file, but the encoding is not essential, and the captured image may be stored in the image file as it is.
