Disclosed herein is a video-image processing apparatus including: a video-image processing section configured to execute output control on video-image streams each including unitary video images appearing along the time axis so as to output every unitary video image pertaining to each of the video-image streams repeatedly a plurality of times by sequentially switching the video-image streams to be output on a time-division basis; a frame memory for temporarily storing an immediately preceding unitary video image as it is or after replacing the luminance gradation of the immediately preceding unitary video image with a post-replacement luminance gradation where the immediately preceding unitary video image is defined as a unitary video image which immediately leads ahead of a current unitary video image being output by the video-image processing section and is selected; and an overdrive processing section configured to carry out overdrive processing on the current unitary video image.
