Abstract
A time-of-flight device comprises a pixel array including a plurality of pixel circuits arranged in an array, respective ones of the plurality of pixel circuits including a first photodiode configured to selectively output two analog signals respectively via two paths, and including a second photodiode configured to selectively output two analog signals respectively via two paths; a signal line coupled to the first photodiode and a second photodiode; and processing circuitry including: a comparator configured to compare a voltage of the signal line with a reference signal and to output a comparison result, and a counter configured to perform a count based on the comparison result in response to a count control signal, wherein the count control signal is configured to switch the counter between an up count mode and a down count mode while a count value is held in the counter.
