Abstract

Provided are an image file creation method and an image file creation device for more effectively using an accessory image as accessory information of a main image.
The present invention relates to an image file creation method of creating an image file including a main image and an accessory image as accessory information related to the main image, the image file creation method including: a type reception step of receiving a type of the accessory image in association with correction processing on the main image; and an acquisition step of acquiring the accessory image that is not changed in conjunction with a change in the main image caused by the correction processing, based on the type.

First claim

What is claimed is:

1 . An image file creation method of creating an image file including a main image and an accessory image as accessory information related to the main image, the image file creation method comprising:
a type reception step of receiving a type of the accessory image in association with correction processing on the main image; and an acquisition step of acquiring the accessory image that is not changed in conjunction with a change in the main image caused by the correction processing, based on the type.

2 . The image file creation method according to claim 1 ,
wherein the acquisition step is carried out in a case in which the correction processing is executed on the main image.

3 . The image file creation method according to claim 1 ,
wherein the correction processing is executed in an imaging device that captures the main image.

4 . The image file creation method according to claim 1 ,
wherein, in the type reception step, at least one of a first accessory image, a second accessory image, or a third accessory image is received as the type, the first accessory image is generated based on a first image obtained by executing development correction processing for development on a RAW image as the main image, the second accessory image is generated based on a second image obtained by executing color correction processing including color correction on the main image, and the third accessory image is generated based on a third image obtained by executing process correction processing for processing a subject in the main image on the main image.

5 . The image file creation method according to claim 4 ,
wherein the development correction processing does not include a portion of a plurality of pieces of the color correction that are executable in the color correction processing.

6 . The image file creation method according to claim 4 ,
wherein, in a case in which two or more types of the accessory images among the first accessory image, the second accessory image, and the third accessory image are acquired, the image file includes the two or more types of the accessory images as the accessory images.

7 . The image file creation method according to claim 4 ,
wherein, in a case in which the third image is acquired by executing the process correction processing on the first image or the second image as the main image included in the image file, the main image included in the image file is replaced with the third image from the first image or the second image.

8 . The image file creation method according to claim 4 , further comprising:
a selection acquisition step of acquiring selection of a user regarding whether or not to acquire the third accessory image in a case in which the process correction processing is executed on the main image, wherein the acquisition step of acquiring the third accessory image is carried out in accordance with the selection in a case in which the process correction processing is executed on the main image.

9 . The image file creation method according to claim 4 , further comprising:
a decision step of deciding whether or not to carry out the acquisition step of acquiring the third accessory image based on a correction content of the main image in a case in which the process correction processing is executed on the main image.

10 . The image file creation method according to claim 1 ,
wherein the accessory information includes information related to the type of the accessory image.

11 . The image file creation method according to claim 1 ,
wherein the accessory information includes information obtained by encrypting the accessory image.

12 . The image file creation method according to claim 11 ,
wherein the information obtained by encrypting the accessory image includes a hash value obtained by hashing the accessory image.

13 . The image file creation method according to claim 1 ,
wherein the accessory image includes a first thumbnail image that is not changed in conjunction with the change in the main image caused by the correction processing and that is generated by reducing an entirety or a part of the main image at a point in time of generation of the accessory image.

14 . The image file creation method according to claim 13 ,
wherein the accessory image includes a second thumbnail image that is changed in conjunction with the change in the main image caused by the correction processing and that is generated by reducing the entirety or a part of the main image.

15 . An image file creation device that creates an image file including a main image and an accessory image as accessory information related to the main image, the image file creation device comprising:
a processor, wherein the processor receives a type of the accessory image in association with correction processing on the main image, and the processor acquires the accessory image that is not changed in conjunction with a change in the main image caused by the correction processing, based on the type.
