Claim 17:
18. A light detecting device, comprising:
a pixel array that includes a plurality of pixel blocks in a matrix, wherein each of the plurality of pixel blocks includes:
a first photoelectric conversion element configured to generate a first electric charge based on an amount of a first incident light;
a detection circuit configured to detect a firing of an address event based on the first electric charge;
a second photoelectric conversion element configured to generate a second electric charge based on an amount of a second incident light; and
a pixel circuit configured to generate a pixel signal based on the second electric charge;

a drive circuit configured to drive a plurality of first pixel blocks of the plurality of pixel blocks to generate a plurality of pixel signals, wherein
the plurality of first pixel blocks is driven based on the detection of the firing of the address event in a first pixel block of the plurality of pixel blocks, and
the plurality of first pixel blocks is in a first row, of the matrix, to which the first pixel block belongs; and

an arbitrator configured to determine, based on a plurality of requests from the plurality of first pixel blocks, a reading order for each row of a plurality of rows to which at least one of the plurality of first pixel blocks belongs.
