摘要： An image processing device including a memory; and at least one image signal processor configured to: generate, using a first neural network, a feature value indicating whether to correct a global pixel value sensed during a unit frame interval, and generate a feature signal including the feature value; generate an image signal by merging the global pixel value with the feature signal; split a pixel value included in the image signal into a first sub-pixel value and a second sub-pixel value, split a frame feature signal included in the image signal into a first sub-feature value corresponding to the first sub-pixel value and a second sub-feature value corresponding to the second sub-pixel value, and generate a first sub-image signal including the first sub-pixel value and the first sub-feature value, and a second sub-image signal including the second sub-pixel value and the second sub-feature value; and sequentially correct the first sub-image signal and the second sub-image signal using a second neural network.

摘要： A decoder includes a parser, an intra predictor, and an inter predictor. The parser parses a bit stream to extract header information and first through third data information, to determine a prediction mode for blocks in a current frame based on the header information, and to selectively output the first and second data information based on the prediction mode. The intra predictor generates a predicted value of a pixel of a current block based on a pixel value of a first reference block in the current frame based on the first data information. The inter predictor predicts a second reference block from a reference frame based on the second data information, converts a pixel value of the second reference block, and generates a predicted value of the pixel of the current block based on a converted pixel value.
