ABSTRACT:
An image processing system includes a coding device configured to code input image data, and a decoding device configured to decode the coded input image data, wherein, if coding and decoding are repeated on the input image data, the image quality of an image corresponding to the input image data is deteriorated. The decoding device includes an input section inputting quantized data in which the input image data is quantized; and a decoding section dequantizing the quantized data that is input by the input section and converting a dequantized value obtained as a result of the quantization into a value in the vicinity of the boundary of a quantization threshold value within a range corresponding to the dequantized value when the quantization is performed.
