Abstract
A signal processing device subjects a signal indicating a moving image constituted by frames to a sharpening process for the moving image, to output a signal indicating the sharpened moving image, and includes: a motion detection section for detecting motion between the frames for each block region including one or a plurality of adjacent pixels constituting each frame; a sharpening process section for subjecting a signal indicating an image of a block region from which motion has been detected to a nonlinear process by a nonlinear process section and sharpening the signal to generate a harmonic; and a signal output section for outputting, for the block region from which motion was detected, the harmonic produced by sharpening a signal indicating a moving image of the block region, while outputting, for a block region from which motion was not detected, a signal indicating a moving image of the block region.
