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 and then rearranged and stored in a same order as the arrangement of the pixels on the image capturing element, and method thereof

摘要

When driven in an all-pixel read mode, a CCD (1) 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 (5) to corresponding image data, which are then temporarily stored in units of a line in a line buffer (7) via a data distributor (6). In this case, an address generator (8) generates, for the respective image data, write addresses to store the respective image data in the line buffer (7) in the same order as the pixels of the photosensitive surface are actually arranged. In accordance with these write addresses, the data distributor (6) distributes the respective image data to appropriate addresses in the line buffer (7), thereby storing the image data there (FIG. 1).
