Abstract:
1. An interpolated frame generating method of generating a new interpolated frame inserted between sequential frames, by using a plurality of input frame images, comprising: first detecting of detecting at least one potential motion vector by block matching processing between the input frame images, using a first block of a fixed size; second detecting of detecting a motion vector by block matching processing between the input frame images, using a second block having a size which is variable within a range larger than that of the first block; adaptively adjusting the size of the second block in accordance with a picture pattern of at least one of the input frame images; generating the interpolated frame by using the potential motion vector when the number of the potential motion vector detected by the first detecting is one, wherein, the generating is generating the interpolated frame by using a potential motion vector, which is closest to the motion vector detected by the second detecting among the potential motion vectors, when a plurality of motion vectors are detected by the first detecting.
