Abstract:
1. A solid-state imaging apparatus comprising: a pixel region including a plurality of pixels arranged in columns, and each pixel performs photoelectric conversion and outputs an analog signal; a plurality of analog-to-digital converters respectively corresponding to the columns of pixels, and each analog-to-digital converter converts an analog signal output by a pixel of a corresponding column into a digital signal; a plurality of digital memories respectively corresponding to the columns of pixels, and each digital memory holds the digital signal converted by the analog-to-digital converter of the corresponding column; first and second block wirings respectively corresponding to mutually different blocks of the plurality of digital memories; a first buffer for buffering an output from the first block wiring; and a second buffer for selectively buffering the output from the first buffer or an output from the second block wiring, an output of the second buffer being coupled to a common digital output line.
