Image processing device setting color conversion method to method adequate for image to be converted

摘要

An image processing device includes a processor and a memory storing computer-readable instructions therein. The computer-readable instructions, when executed by the processor, cause the image processing device to perform: acquiring a plurality of hue values from a plurality of pixels of the image; determining an index value of the image based on the plurality of hue values, the index value representing a degree of change in hue of the image before and after executing a color conversion on the image; and setting a color conversion method to a first method when the index value represents that the degree of change in hue of the image is comparatively low, and setting the color conversion method to a second method when the index value represents that the degree of change in hue of the image is comparatively high.

1. An image processing device comprising:
a processor; and a memory storing computer-readable instructions therein, the computer-readable instructions, when executed by the processor, causing the image processing device to perform: acquiring a plurality of hue values from an image, the image including the plurality of pixels having a plurality of hue values, each of the plurality of pixels having corresponding one of the plurality of hue values, each of the plurality of hue values indicating hue of corresponding one of the plurality of pixels; determining an index value of the image based on the plurality of hue values, the index value representing a degree of change in hue of the image before and after executing a color conversion on the image; and setting a color conversion method to a first method when the index value represents that the degree of change in hue of the image is comparatively low, and setting the color conversion method to a second method when the index value represents that the degree of change in hue of the image is comparatively high, the second method being different from the first method; wherein a processing load incurred by the first method is lower than a processing load incurred by the second method; wherein a possibility that the hue of the image changes after color conversion is executed according to the first method is higher than a possibility that the hue of the image changes after color conversion is executed according to the second method.
