摘要：PROBLEM TO BE SOLVED: To generate progressive images of high image quality when sequential scan conversion is performed. SOLUTION: A gamma compensation part 13 performs gamma compensation, based on a gamma compensation value corresponding to a display device 30 with respect to image data of fields input before and after a present field, and a movement detection part 14 uses gamma-corrected image data to detect movements. Thus movements can be detected with respect to the same gamma-compensated image data as image data actually displayed on the display device, and unnecessary interpolation processing and the occurrence of combing noise due to missing movements can be prevented, and the image quality of progressive images is improved when sequential scan conversion is performed.
