Classification: CPC H  B | IPC H

Claim 9:
10. A light detecting device comprising:
a first pixel including a first photodiode;
a second pixel including a second photodiode;
a first signal line coupled to the first pixel, the first signal line extending along a first direction;
a second signal line coupled to the second pixel, the first second line extending along the first direction;
a first analog-to-digital converter coupled to the first signal line;
a second analog-to-digital converter coupled to the second signal line;
a first control line extending along a second direction perpendicular to the first direction;
a second control line extending along the second direction;
a signal generator coupled to the first control line and the second control line;
a first transistor having a source or a drain coupled to the first signal line and a gate coupled to the first control line;
a second transistor having a source or a drain coupled to the second signal line and a gate coupled to the second control line; and
diagnosis circuitry configured to detect an error based on a digital code generated from the first analog-to-digital converter or the second analog-to-digital converter,
wherein the first pixel and the second pixel are in a pixel column extending along the first direction.
