摘要： According to one embodiment, an interpolation frame generating method includes detecting a motion vector of an object in input frame images by block matching processing between the input frame images, generating an interpolation frame by using the detected motion vector, and inserting the interpolation frame between the input image frames. The detecting includes calculating an absolute difference value between values of each pair of pixels located in same position in respective image blocks which are located in positions corresponding to each other on former and latter frames of the input frame images. A vector based on positions of a pair of blocks on the former and latter frames having minimum SAD indicating a cumulative sum value of the absolute difference values is selected as the motion vector. When the absolute difference value is larger than a predetermined value, the difference value is changed, and a possibility of erroneous detection of motion vector is reduced.
