An image processing method for converting the frame frequency of a video signal includes a first step for subjecting a video signal having a first frame-frequency to three-times-repeat output and two-times-repeat output of a frame to convert the video signal having the first frame-frequency into a video signal having a second frame-frequency holding a relation of 2:5 as to the first frame-frequency; and a second step for converting the video signal having said second frame-frequency converted in said first step into a video signal having a third frame-frequency holding a relation of 1000:1001 or 1001:1000 as to the second frame-frequency, wherein the second step performs the conversion such that the difference of the number of frames after conversion becomes one or less between a frame group based on the three-times-repeat output frame in the first step, and a frame group based on the two-times-repeat output frame in the first step.
