Solid-state imaging device and signal processing device

A solid-state imaging device comprising:

• a plurality of pixels arranged to form a plurality of rows and a plurality of columns;
• and
• a readout circuit that reads out signals from an associated pixel of the plurality of pixels,
• wherein each of the plurality of pixels includes a first photoelectric converter, a second photoelectric converter arranged in a first direction with respect to the first photoelectric converter, a third photoelectric converter arranged in a second direction intersecting with the first direction with respect to the first photoelectric converter, a fourth photoelectric converter arranged in the second direction with respect to the second photoelectric converter and in the first direction with respect to the third photoelectric converter, and a single micro lens that converges light to the first to fourth photoelectric converters,
• wherein
• the readout circuit is configured to read out a plurality of signals from the associated pixel by three times of readout operations,
• within the three times of readout operations, charges from all of the first to fourth photoelectric converters of the associated pixel are read out so that the charges of each of the first to fourth photoelectric converters are reflected to at least one of the plurality of signals,
• the readout circuit is configured to read out the plurality of signals from the associated pixel so as to be able to identify a signal based on charges generated by only one photoelectric converter out of the first to fourth photoelectric converters of the associated pixel, and
• the readout circuit is configured to select the one photoelectric converter of the associated pixel out of the first to fourth photoelectric converters.
