Abstract

The present invention pertains to a solid-state imaging element, a method for driving the element, and a camera system, that enable suppression of white blur at the edge of an image due to the effect of a peripheral circuit. The present invention has: a pixel part in which a plurality of pixels are arranged in a line, the pixel part including a photoelectric conversion element for converting an optical signal to an electrical signal and storing the signal charge, the signal charge being dependent on the exposure time; a peripheral circuit disposed adjacent to an edge portion in a mutually facing arrangement with the pixel part, and driven in association with the read operation of at least a pixel signal; and a pixel-signal read unit for reading the pixel signal from the pixel part in a plurality of pixel units. When the pixel-signal read unit reads all the pixels, all the pixels are reset, and the pixels are then read alternately at least one line at a time starting from at least the lines in a specified region near the peripheral circuit disposed toward the edge portion in a mutually facing arrangement with the pixel part.

Description

technical field [0001] The present invention relates to a solid-state imaging device that performs full-pixel readout, a method of driving the solid-state imaging device, and a camera system. Background technique [0002] In recent years, although image sensors have high resolution, image sensors are still required to image high-quality images at low resolution. [0003] For example, functions such as capturing moving images with digital still cameras and, conversely, imaging still images with video cameras are gaining popularity. [0004] Also, such electronic devices often have a viewfinder for confirming a picture, but the resolution of the viewfinder is generally lower than that of an imaged image. [0005] Also, some digital still cameras and mobile phones incorporate the ability to increase frame rates when imaging at low resolutions in order to image high-speed motion that is conventionally unrecognizable. [0006] As previously described, only one image sensor need...
