Claim 9:
10. A circuit device comprising:
a color reduction circuit configured to execute color reduction processing from input image data in which pixel data is m bits, m being an integer of 2 or more, to color reduced image data in which pixel data is n bits, n being an integer of 1 or more and less than m, and configured to execute error diffusion processing in a space direction or in a time direction in the color reduction processing;
a storage circuit storing the color reduced image data; and
an image conversion circuit configured to execute image coordinate conversion processing, which is at least one of mapping processing and scaling processing, on the color reduced image data stored in the storage circuit to output output image data, and configured to execute interpolation processing, which is in the image coordinate conversion processing, of generating pixel data of the output image data from a plurality of pieces of pixel data of the color reduced image data.
