A signal readout circuit is a circuit for reading out a signal from a photodetection element having a plurality of photodetection pixels each generating a detection signal according to light incidence, and includes N light incidence detection units (N is an integer of 2 or more) each for inputting the detection signal from each of N photodetection pixels and outputting a signal indicating the light incidence, and a total value detection unit for detecting a total value of the output signals from the N light incidence detection units. Each light incidence detection unit outputs the signal weighted differently corresponding to each photodetection pixel. A weight thereof is set such that the total values are different for respective photodetection pixels and all combination patterns of the photodetection pixels.
