Abstract:
Provided is a motion compensating apparatus that efficiently generates a motion-compensated pixel by reducing the amount of data to be transmitted from a multi frame memory storing reference pixel data, while minimizing an increase in the scale of a circuit. A motion compensating apparatus (100) includes: a motion compensation position determining unit (101) that determines, based on a motion vector, a position of pixels for which compensated pixels should be generated; a necessary pixel determining unit (102) that determines pixels necessary for performing 6-tap filtering; a data transfer controlling unit (103) that controls the order or the like of taking out data to be transferred; an intermediate pixel storage memory (105) for storing pixel data with half-pixel accuracy; a high-order tap filtering unit (106) that generates pixel data with half-pixel accuracy by successively performing filtering operations in a predetermined direction; and a linear interpolation calculating unit (107) that performs linear interpolation based on the position of pixels to be motion compensated, and generates and outputs pixel data with motion compensation accuracy of less than half-pixel accuracy.
