Abstract
It is an object of the present invention to provide a solid-state imaging apparatus that outputs digital signals at high speed. A solid-state imaging apparatus is provided that includes plural analog-to-digital converters that convert analog signals obtained by photoelectric conversion into digital signals, plural digital memories that store the digital signals converted by the analog-to-digital converters, plural block digital output lines that are provided to correspond to blocks of the plural digital memories and to which the digital signals stored in the plural digital memories included in the blocks are output, a common digital output line that outputs the digital signals output from the plural block digital output lines, buffer circuits that buffer the digital signals output from the block digital output lines, and block selecting units that can switch the block digital output lines electrically connected to the common digital output line.
