Image processing circuit, display device, and printing device

摘要

An image processing circuit includes: a storage unit; a first multiplication unit that multiplies a pixel value stored in the storage unit, by a pixel value included in input image data, the input image data expressing the pixel values; a subtraction value output unit that outputs a pixel value obtained by subtracting a pixel value at each of the positions in the input image data, from a maximum pixel value in the input image data; a second multiplication unit that multiplies a pixel value included in the input image data or a pixel value included in background image data, by the pixel value output by the subtraction value output unit; and an adder unit that adds up a multiplication result of the first and second multiplication units and outputs addition results as output image data.
