Claim 6:
7. The light detecting device of claim 1, further comprising:
a second pixel including a second photodiode;
a second signal line coupled to the second pixel, the second signal line extending along the first direction;
a second analog-to-digital converter coupled to the second signal line;
a second control line extending along the second direction and being coupled to the second control line; and
a second transistor having a source or a drain coupled to the second signal line and a gate coupled to the second control line,
wherein the second analog-to-digital converter is configured to generate a third digital code based on a third signal output from the second pixel in the first period,
wherein the signal generator is configured to output a second control signal to the second control line in the second period,
wherein the second analog-to-digital converter s configured to generate a fourth digital code based on a fourth signal outputted from the second transistor corresponding the second control signal in the second period, and
wherein the diagnosis circuitry is configured to diagnose a second signal path including the second signal line based on the fourth digital code.
