Abstract:
1. An image processing device for predicting lower-order bits of target pixel data, based on one or more pieces of pixel data constituting image data, comprising: a lower-order bit calculation unit for calculating the lower-order bits of the target pixel data, based on the one or more pieces of pixel data constituting the image data and specifying the calculated lower-order bits of the target pixel data as corrected lower-order bits; a lower-order bit superimposition unit for adding the corrected lower-order bits calculated by the lower-order bit calculation unit to higher-order bits of the target pixel data, and integrating image data that represents an image; and a memory for storing the superimposition result of the lower-order bit superimposition unit as a pixel data that represents a portion of the image, wherein the higher-order bits and lower-order bits constitute image data that represents the image.
