Abstract
There is provided a pixel circuit capable of outputting time difference data or image data, and including a first temporal circuit and a second temporal circuit. The first temporal circuit is used to store detected light energy of a first interval and a second interval as the time difference data. The second temporal circuit is used to store detected light energy of the second interval as the image data. The pixel circuit is used to output a pulse width signal corresponding to the time difference data or the image data in different operating modes.
