Abstract
A 3D camera uses a modulated visible light source for depth imaging and includes a processor operable to perform time multiplexing between image detection and depth or time-of-flight (ToF) detection using the same photodetectors. The camera can alternate between the image detection mode and the ToF detection mode to produce a continuous stream of color and depth images that can be overlaid without the need for any post-processing software. The camera can also be configured to determine time-of-flight using analog integration modules, thereby minimizing the circuitry necessary for analog-to-digital conversions and ToF calculations in the digital domain.
