PROBLEM TO BE SOLVED: To improve image quality, and to perform image quality conversion processing capable of coping with various conversion patterns by a simple constitution.SOLUTION: In a regression prediction operation and a discrimination prediction operation, a plurality of pixel values corresponding to the attention pixel of an input image or feature amounts obtained from the values are given as parameters. Four extraction values which are the plurality of pixel values corresponding to the attention pixel of the input image and the three feature amounts obtained from the values are used. The four extraction values are the pixel value extracted according to a moving direction, the maximum value and minimum value of the extracted pixel value, the absolute value of a differential feature amount according to the moving direction of the extracted pixel value, and the maximum value of the absolute value of the differential feature amount according to the moving direction of the extracted pixel value. |
