Abstract
Provided is an image processing device which performs scaling and applies super-resolution in accordance with the complexity of the image. On the compression side, a complexity calculation unit calculates the transmission image complexity, which indicates the complexity of the input image, multiplexes and outputs it to an encoded stream, and a control unit configures the cutoff frequency of a low pass filter and the scaling coefficient of an image reduction unit in accordance with the transmission image complexity. On the decompression side, a complexity calculation unit calculates the decoded image complexity indicating the complexity of a decoded and expanded image, a complexity comparison unit compares the transmission image complexity and the decoded image complexity and outputs the difference or ratio, and, on the basis of output, a parameter calculation unit optimizes and configures the scaling coefficient of an image enlargement unit and the folding frequency of a super-resolution processing unit.
