Abstract
We propose a CMOS image sensor with time-divi sion
multiplexing pixel architecture using standard pinned-photodiode
for capturing 2-D color image as well as extracting 3-D depth in-
formation of a target object. The proposed pixe l can alternately
provide both color and depth images in each frame. Two split pho-
todiode and four transfer gates in each pixel improve the transfer
speed of generated electrons to be capable o f demodulating a high-
frequency time-of- flight signal. In addition, four-
