Abstract: An image processing apparatus includes a saturation judgment section adapted to judge whether or not saturation of individual pixels making up image data of plural images falls within a high saturation area, the image data being acquired by picking up images of an object in time sequence; and an image combining section adapted to perform high-saturation comparative bright combination processing on the image data of plural images, where the high-saturation comparative bright combination processing involves replacing only pixels judged to fall within the high saturation area with a pixel value of a pixel which has a larger index including a luminance component.

Abstract: A data processing apparatus includes a data output section configured to output serial data associated with video information through one or more lanes and a data processing section configured to process the serial data by supplying power from a power supply section to a receiving section configured to receive the serial data. The data processing section turns off the power supply to the receiving section while maintaining an output state of the data output section for a known ineffective period, turns on the power supply to the receiving section prior to the start of an effective period, then detects starting information based on a predetermined code included in the serial data and establishes a receiving operation of the receiving section.
