摘要： An image processing apparatus capable of achieving compatibility between extension of a viewing angle characteristic and an improvement in motion picture response while reducing a sense of flicker in an image display having a sub-pixel configuration is provided. The image processing apparatus includes: a detection means for detecting a motion index and/or an edge index of an input picture for each pixel; a frame division means for dividing a unit frame period of the input picture into a plurality of sub-frame periods; and a gray-scale conversion means for selectively performing adaptive gray-scale conversion on luminance in a pixel where a motion index and/or an edge index larger than a predetermined threshold value is detected so that, while allowing the time integral value of the luminance signal within the unit frame period to be maintained as it is, a high luminance period and a low luminance period are allocated to sub-frame periods in the unit frame period, respectively. The gray-scale conversion means performs adaptive gray-scale conversion on luminance for each sub-pixel so that the plurality of sub-pixels in each pixel have different display luminance from each other.

摘要： To realize a motion compensation device capable of more appropriately compensating the movement of a video signal subjected to double-speed conversion. A motion vector between an image of a current field in a double-speed-converted video signal and an image of a reference field that is one frame or two frames later is detected, the pixels of the current field are shifted based on the motion vector and the pixels of the reference field are shifted in an opposite direction based on the motion vector. Then simple averaging or weighted average according to the shift amount is performed on the pixels of the current field and the pixels of the reference field to compensate the current field, thereby being capable of compensating the movement between fields so as to be much smoother than conventional cases.
