PROBLEM TO BE SOLVED: To suppress expansion of hardware size and speed up color conversion processing with hardware.SOLUTION: An image processor G includes: a memory 15; a control part 16 which switches to an LUT of attributes of a color conversion target to save in the memory 15; a detection part 12 which detects a pixel having attribute data of the color conversion target in a subblock obtained by dividing a block; an input buffer 11 which outputs the image data of the subblock in which the pixel is detected to a color conversion part and outputs the image data of the subblock in which the pixel is not detected to an output buffer; a color conversion part 14 which performs color conversion of the pixel having the attribute data of the color conversion target, among the image data of the subblock outputted from the input buffer 11, and outputs it to the output buffer, using the LUT saved in the memory 15; and an output buffer 17 which outputs the image data of the subblock which is outputted from the color conversion part 14 or the input buffer 11. |
