1. A solid-state imaging device comprising:
MN pixels each including a photodiode configured to generate charges by receiving light and arrayed two-dimensionally in M rows and N columns (M and N are each an integer of 2 or more);
a row control unit coupled to N pixels of an m-th row (m is an integer of 1 or more and M or less) in the M rows and the N columns by an m-th row control line, and configured to apply an m-th row control signal to the N pixels of the m-th row via the m-th row control line;
a row readout unit coupled to the N pixels of the m-th row in the M rows and the N columns by an m-th row output line, and configured to input the charges generated in the photodiode of each of the N pixels of the m-th row and output to the m-th row output line;
a column control unit coupled to M pixels of an n-th column (n is an integer of 1 or more and N or less) in the M rows and the N columns by an n-th column control line, and configured to apply an n-th column control signal to the M pixels of the n-th column via the n-th column control line; and
a column readout unit coupled to the M pixels of the n-th column in the M rows and the N columns by an n-th column output line, and configured to input the charges generated in the photodiode of each of the M pixels of the n-th column and output to the n-th column output line, wherein
the pixel of the m-th row and the n-th column in the MN pixels is configured to select whether the charges generated in the photodiode are output to the m-th row output line based on logical values of both the m-th row control signal and the n-th column control signal, and select whether the charges generated in the photodiode are output to the n-th column output line based on logical values of both the m-th row control signal and the n-th column control signal.
