  • Publication number: 20240314458
    Abstract: In a solid state imaging element in which signal processing is performed on a pair of pixel signals, the circuit scale thereof is reduced. The solid state imaging element includes a pixel array section, a vertical scanning circuit, and a signal processing circuit. A plurality of pixels are arranged in directions of rows and directions of columns on the pixel array section. The vertical scanning circuit selects, from among the plurality of pixels, a pair of pixels disposed on both ends of a predetermined line segment, which does not match any of the rows and columns and forms an angle of not 45 degrees with respect to the rows, and causes the selected pixels to simultaneously output of a pair of pixel signals. The signal processing circuit performs predetermined signal processing on the pair of pixel signals.
