Claim 13:
14. A light detecting device comprising:
a first pixel including a first photodiode;
a first signal line coupled to the first pixel, the first signal line extending along a first direction;
a first analog-to-digital converter coupled to the first signal line;
a first control line extending along a second direction;
a signal generator coupled to the first 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;
