Abstract
There is provided a pixel circuit capable of outputting time difference data and image data, and including an image circuit and a difference circuit. The image circuit is used to record and output detected light energy of a first interval as the image data. The difference circuit is used to record and output a variation of detected light energy between the first interval and a second interval as the time difference data. The pixel circuit selects to output at least one of the time difference data and the image data.
