Abstract: A pixel array including pixels arranged in a matrix shape is provided. The pixels have a same structure and are separated from each other by front deep trench isolation (FDTI). A first pixel among the pixels includes a first floating diffusion region, a first group of photoelectric conversion elements, a first group of charge transfer transistors, a first source follower transistor, and a first transistor, a second transistor, and a first reset transistor connected in series between the first floating diffusion region and a voltage supply line. One of the first transistor, the second transistor, and the first reset transistor is formed in a first sub-pixel region. At least another one of the first transistor, the second transistor, and the first reset transistor is formed in a second sub-pixel region. The first sub-pixel region and the second sub-pixel region are separated from each other by the FDTI.

Abstract: An electronic device includes an image sensor that generates image data, and an image processor that processes the image data. The image sensor includes a pixel array including pixels repeatedly disposed along a row direction and a column direction. Each of pixels belonging to a first row of rows of the pixel array includes sub-pixels each connected to one of a first transmission metal line, a second transmission metal line, and a third transmission metal line. In response to signals respectively applied to the first to third transmission metal lines, at least a part of charges integrated at the sub-pixels of the pixels belonging to the first row from among the pixels is diffused to corresponding floating diffusion areas.
