Patent ID: 8405771

Claim:
A frame rate conversion apparatus that divides an input frame into a plurality of subframes and performs frame rate conversion, comprising: a detection unit that detects a degree of motion of the input frame; a generation unit that generates a filter factor for use in filtering, according to the degree of motion detected by said detection unit; a filtering unit that filters the input frame based on the filter factor generated by said generation unit; and an output unit that divides the frame obtained as a result of the filtering by said filtering unit into a plurality of subframes and outputs the subframes, wherein said output unit includes: a division processing unit that divides the frame obtained as a result of the filtering by said filtering unit into first subframes; a differential processing unit that generates second subframes from a difference between the first subframes and the input frame; and a switching unit that switches between outputting the first subframes and outputting the second subframes during a single frame time.
