Color conversion method of color conversion apparatus and image data of the image data

摘要

The first color conversion circuit (10) performs the first color conversion of the whole image of the image data by the first color conversion circuit (10), and the second color conversion circuit By adding a correction signal multiplied by the key signal (4) indicating the region of a specific color to the entire image in the image, the second color conversion is performed only in the region of the color, and the key signal (4) is generated by the key signal generating circuit (30) by the first color conversion circuit (10) Since it is generated from the image data supplied to the second stage, the output result of the second color conversion circuit (20) of the specific color of the subsequent stage can be prevented from being affected by the output result of the first color conversion circuit (10) of the whole image of the preceding stage.
