Abstract

An image capturing apparatus comprises: an image sensor configured to sense an image and output image data; an image processing unit configured to perform image processing on the image data; an output unit configured to output the processed image data to an external image processing apparatus; an input unit configured to input first processing information used in image processing performed by the external image processing apparatus on the image data; and a recording unit configured to record the first processing information, second processing information used for converting image data into standard image data, and at least one of the image data processed by the image processing unit and the unprocessed image data, in association with the stated image data.

First claim

What is claimed is:

1. An image capturing apparatus comprising:
an image sensor configured to sense an image and output image data;
a transmitter configured to transmit the image data to an external image processing apparatus;
a receiver configured to receive processing information used in image processing performed by the external image processing apparatus on the image data, wherein the image processing includes first image processing that converts the image data into standard image data defined in a predetermined color space and second image processing that is performed on the standard image data in accordance with an operation by a user; and
a recorder configured to record in an image file the processing information in association with the image data that has not been processed by the external image processing apparatus,
wherein the processing information is information about the second image processing,
wherein, in a case where content of the second image processing performed by the external image processing apparatus is changed, the receiver receives processing information corresponding to the changed second image processing from the external image processing apparatus, and
wherein, upon receiving the processing information corresponding to the changed second image processing, the recorder creates a new image file and records in the created image file the processing information in association with the image data.

2. The image capturing apparatus according to claim 1 , wherein the recorder records the processing information as appended information of the image data.

3. The image capturing apparatus according to claim 1 , wherein the processing information is link information indicating a link to a file containing parameters used in the image processing performed by the external image processing apparatus on the standard image data.

4. The image capturing apparatus according to claim 1 , wherein the processing information is a program of the image processing to be performed by the external image processing apparatus on the standard image data.

5. The image capturing apparatus according to claim 1 , wherein the standard image data is based on the Academy Color Encode Specification (ACES) standard.

6. The image capturing apparatus according to claim 1 , wherein the processing information is a three-dimensional look-up table.

7. An image processing apparatus comprising:
a reader configured to read out the processing information and the image data recorded into the recorder by the image capturing apparatus according to claim 1 ;
a converter configured to convert the image data into standard image data based on a standard;
a first image processor configured to perform the same processing as the processing performed by the external image processing apparatus on the image data, on the standard image data obtained through the conversion performed by the converter, based on the processing information; and
a second image processor configured to perform image processing based on a designation from a user on the image data processed by the first image processor.

8. The image processing apparatus according to claim 7 , further comprising a transmitter configured to transmit the image data processed by the second image processor to a display device.

9. A control method for an image capturing apparatus including an image sensor configured to sense an image and output image data, the method comprising:
transmitting the image data to an external image processing apparatus;
receiving processing information used in image processing performed by the external image processing apparatus on the image data; and
recording in an image file the processing information in association with the image data that has not been processed by the external image processing apparatus,
wherein the image processing includes first image processing that converts the image data into standard image data defined in a predetermined color space and second image processing that is performed on the converted image data in accordance with an operation by a user, and
wherein the processing information is information used in about the second image processing,
wherein, in a case where content of the second image processing performed by the external image processing apparatus is changed, processing information corresponding to the changed second image processing is received from the external image processing apparatus, and
wherein, upon receiving the processing information corresponding to the changed second image processing, a new image file is created and the processing information is recorded in the created image file in association with the image data.
