Abstract: An image pickup apparatus includes an image sensor including a plurality of normal pixels and OB pixels obtained by dividing each pixel into n, and an image processing circuit. The image sensor can read each pixel row in a first read mode in which a pixel signal is generated and read or in a second read mode in which n signals relating to n divided pixel signals are read in n rows. The image processing circuit performs processing on signals read in the first and second read modes to generate image data and performs OB level correction processing on a normal pixel signal read from the normal pixels in the second read mode using an OB pixel signal read from the OB pixels in the first and second read modes.

Abstract: A pixel region includes: pixels each including a plurality of photoelectric conversion devices; a light-shielding region; and an effective region. A reading circuit reads, from a first row of the pixel region, a pixel signal obtained by adding signals of the plurality of photoelectric conversion devices, and reads, from a second row of the pixel region, a plurality of signals including phase difference information. A horizontal streak correction circuit performs one of a first offset correction based on a signal read from the light-shielding region and a second offset correction based on a predetermined value on a pixel signal obtained from a second row of the effective region. An image processing circuit processes image data according to a parameter. The horizontal streak correction circuit selects the first offset correction or the second offset correction according to the parameter.

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.
