Patent ID: 8411185

Claim:
A solid-state imaging apparatus comprising: a plurality of unit cell groups, each of the unit cell groups including a plurality unit cells; and common output lines, wherein each of the unit cells includes: a plurality of pixels each including a photoelectric conversion element corresponding to one of different colors; a plurality of holding units each corresponding to one of the different colors, for holding a signal from the pixels; a selecting switch arranged at a stage following the holding units, for selecting the signal held by the holding unit; and a transfer switch arranged at a stage following the selecting switch, for outputting the signal selected by the selecting switch to one of the common output lines, and wherein the plurality of unit cell groups include: a first unit cell group including a plurality of the transfer switches, each of the transfer switches including an output node connected to a first common output lines among the common output lines, and a second unit cell group including a plurality of the transfer switches, each of the transfer switches including an output node connected to a second common output line among the common output lines, but not to the first common output line, and wherein all of the signals from each one of the plurality of unit cell groups are read out in parallel through a corresponding one of the transfer switches to a corresponding common output line.
