Frame rate conversion apparatus and control method thereof

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.
