Claim One:
1. An image processing device for correcting frame picture data in accordance with a correction parameter, comprising: a generation unit that generates frame feature data indicating features of an edge image shown in the frame picture data; a calculation unit that calculates, from each of pixel blocks constituting the frame picture data, a motion vector indicating a movement between the frame picture data and previous frame picture data; a region specification unit that, in accordance with motion vectors calculated from the pixel blocks, specifies a region to be masked in the frame feature data; and a detection unit that detects the correction parameter from an unmasked region of the frame feature data, wherein the region to be masked corresponds to (i) a pixel block whose motion vector indicates a movement amount larger than a predetermined threshold, and (ii) a pixel block whose motion vector indicates a different directional component than a predetermined directional component, and wherein the predetermined directional component is a direction shown by a pixel block that is proportional to a counterpart pixel block thereof included in the previous frame picture data.
