PROBLEM TO BE SOLVED: To prevent deterioration in picture quality as far as possible. SOLUTION: The system has an image signal converting section 10 that is provided with an input change-over switch section 12 which takes in the frame image of an image to be displayed based on input image signals and input synchronization signals, input frame memories 131 to 13m which record the frame image taken in by the section 12, a black raster image generating section 14 which generates a black raster image, an image conversion processing section 15 which generates an interpolation image or insert the black raster image between frame images corresponding to image information based on the image information, the input synchronization signals and output synchronization signals or generates an output frame image from the input frame image recorded in the input frame memories by thinning out the frame images, output frame memories 171 to 17n which record the output frame images and an output control switch section 18 which takes out the output image signals and the output synchronization signals from the output frame image recorded in the output frame memories and transmits the signals to a display device 50.
