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： An image processing apparatus includes: a detection means for detecting a motion index of an input picture; a generation means for generating a mask signal for a fluctuation pixel region due to a line flicker component; a mask processing means for performing a mask process on the motion index through the use of the mask signal; a frame division means; and a gray-scale conversion means for selectively performing, on the basis of the motion index subjected to the mask process, adaptive gray-scale conversion on a luminance signal in a pixel region where a motion index is larger than a predetermined threshold value so that, while maintaining total time integral value of the luminance signal in the unit frame period as it is, a high luminance period and a low luminance period are allocated to sub-frame periods in the unit frame period, respectively.
