Abstract:
1. An image sensor comprising: a light source that emits modulated light to a target object; a plurality of pixels that comprises at least one pixel for outputting pixel signals according to light reflected by the target object; an image processing unit that simultaneously generates a color image and a depth image from the pixel signals of the at least one pixel; and a row decoder that outputs gate signals having predetermined phase differences from the modulated light to the at least one pixel outputting the pixel signals, wherein the at least one pixel comprises a photo-gate that responds to the gate signals in a photoelectric conversion area, and wherein the gate signals include first through fourth gate signals respectively having phase differences of 0, 90, 180, and 270 degrees from the modulated light, which are applied by the row decoder sequentially to the photo-gate to output first through fourth pixel signals.
