An image processing system is comprised of a conversion parameter calculating means, a initial image generating mean, a high resolution image generating means, and an input image and conversion parameter memory means.
[PROBLEMS] In a system for converting a low resolution image to a high resolution image, it is difficult to carry out real-time processing to generate a high resolution image for each frame by using continuous frame image on a basis of time. [MEANS FOR SOLVING THE PROBLEMS] An image processing system is comprised of a conversion parameter calculating means (101), a initial image generating means (102), a high resolution image generating means (103), and an input image and conversion parameter memory means (110), wherein based on a conversion parameter for the present frame against the previous frame, a high resolution image generated in the previous frame is converted to an image for the present frame and processing to generate a high resolution image for the present frame is carried out for the converted image as an initial value.
