Abstract
To make it possible to specify a color space of image data even in a case where color space identification information is not attached to the image data. The image processing system that handles image data whose color spaces are different comprises a learning unit configured to perform machine learning by taking image data and metadata thereof as input data and color space identification information as supervised data. In the machine learning, a learning model is optimized so that a deviation between the color space predicted from the input data and the color space specified by the color space identification information becomes a minimum.
Claims14
A printing apparatus comprising:
- at least one memory that stores a program;
- and
- at least one processor that executes the program to perform:
- receiving an image file including image data to be printed;
- requesting for, in a case where it is not possible to specify a color space of the image data from the image file, inference of the color space of the image data by using a learning model;
- determining the color space of the image data based on inference results corresponding to the request;
- and
- performing printing processing of the image data based on the determined color space, wherein
- in the inference, at least one of image information obtained by analyzing the image data included in the image file and image capturing information relating to image capturing processing for obtaining the image data is input to the learning model and information indicating the color space of the image data is output from the learning model as the inference results.
A control method performed in a printing apparatus, the control method comprising:
- receiving an image file including printing-target image data;
- requesting for, in a case where it is not possible to specify a color space of the image data from the image file, inference of the color space of the image data by using a learning model;
- determining the color space of the image data based on inference results corresponding to the request;
- and
- performing printing processing of the image data based on the determined color space, wherein
- in the inference, at least one of image information obtained by analyzing the image data included in the image file and image capturing information relating to image capturing processing for obtaining the image data is input to the learning model and information indicating the color space of the image data is output from the learning model as the inference results.
