Abstract:
1. A frame rate conversion apparatus that converts a frame rate of a synthesized moving image which is a moving image synthesized with a still image, by inserting an interpolation frame between frames of the synthesized moving image, the apparatus comprising: a detection unit that generates motion information by detecting motion of a picture at each pixel location from a moving image which is not synthesized with a still image; a synthesizing unit that generates a synthesized moving image by synthesizing a still image on a blending region in the moving image at a prescribed opacity; a judgment unit that determines whether or not a pixel of interest of an interpolation frame to be inserted between frames of the synthesized moving image generated by the synthesizing unit is a pixel within the blending region; and a generation unit that generates the interpolation frame, wherein the generation unit (a) sets a value of the pixel of interest to be a value of a pixel at the same location as the pixel of interest in a frame of the synthesized moving image before or after the interpolation frame in a case where the pixel of interest is determined to be a pixel within the blending region, and (b) sets a value of the pixel of interest based on a value of a corresponding pixel at a location specified by motion information corresponding to the pixel of interest in at least one of frames of the synthesized moving image before and after the interpolation frame in a case where the pixel of interest is determined to not be within the blending region, wherein the detection unit and the synthesizing unit are connected with the generation unit, and wherein the detection unit is not connected with the synthesizing unit.
