Image capturing apparatus in which pixel charge signals are divided and output in a different order than an arrangement of pixels on an image capturing element, stored in units of a horizontal line, and read in a same order that corresponding pixels are arranged on the image capturing element, and method thereof

摘要

When driven in an all-pixel read mode, a CCD outputs, with each horizontal sync timing signal, captured image signals including signal charges arranged in a different order from that in which the pixels are actually arranged on a photosensitive surface of the CCD. During this time, the respective pixel signals are digitized sequentially by an A/D converter to corresponding image data, which are then temporarily stored in units of a line in a line buffer via a data distributor. In this case, an address generator generates, for the respective image data, write addresses to store the respective image data in the line buffer in the same order as the pixels of the photosensitive surface are actually arranged. In accordance with these write addresses, the data distributor distributes the respective image data to appropriate addresses in the line buffer, thereby storing the image data there.
