Abstract
Luminance data indicating luminance of the print product illuminated by the lighting is calculated and processing for causing a high luminance region to have gradation characteristics is performed.
Claims21
An image processing apparatus, comprising:
- a processor;
- and
- a memory coupled to the processor storing instructions that, when executed by the processor, cause the processor to function as:
- a print processing unit configured to receive an image data to be output to a printing apparatus for printing a print product, and to receive illumination condition data of a lighting apparatus;
- an acquisition unit configured to acquire a first value indicating a maximum luminance value of the print product illuminated by the lighting apparatus based on the image data and the illumination condition data, and a second value indicating a maximum luminance value displayable by an image display apparatus;
- a generation unit configured to generate preview image data to be displayed on the image display apparatus by converting the image data based on the first value and the second value;
- and
- an output unit configured to output the generated preview image data to the image display apparatus,
- wherein, in a case where the first value is greater than the second value, the generation unit generates the preview image data so that a maximum luminance value of the preview image data is less than or equal to the second value.

An image processing method, comprising:
- receiving an image data to be output to a printing apparatus for printing a print product, and receiving illumination condition data of a lighting apparatus;
- acquiring a first value indicating a maximum luminance value of the print product illuminated by the lighting apparatus based on the image data and the illumination condition data, and a second value indicating a maximum luminance value displayable by an image display apparatus;
- generating preview image data to be displayed on the image display apparatus by converting the image data based on the acquired first and second values;
- and
- outputting the generated preview image data to the image display apparatus,
- wherein, in a case where the first value is greater than the second value, the generation unit generates the preview image data so that a maximum luminance value of the preview image data is less than or equal to the second value.

A non-statutory storage medium storing a program to cause a computer to execute an image processing method, the method comprising:
- receiving an image data to be output to a printing apparatus for printing a print product, and receiving illumination condition data of a lighting apparatus;
- acquiring a first value indicating a maximum luminance value of the print product illuminated by the lighting apparatus based on the image data and the illumination condition data, and a second value indicating a maximum luminance value displayable by an image display apparatus;
- generating preview image data to be displayed on the image display apparatus by converting the image data based on the acquired first and second values;
- and
- outputting the generated preview image data to the image display apparatus,
- wherein, in a case where the first value is greater than the second value, the generation unit generates the preview image data so that a maximum luminance value of the preview image data is less than or equal to the second value.
