A video projector device includes a visible light projector to project an image on a surface or object, and a visible light sensor, which can be used to obtain depth data regarding the object using a time-of-flight principle. The sensor can be a charge-coupled device which obtains color images as well as obtaining depth data. The projected light can be provided in successive frames. A frame can include a gated sub-frame of pulsed light followed by continuous light, while the sensor is gated, to obtain time of flight data, an ungated sub-frame of pulsed light followed by continuous light, while the sensor is ungated, to obtain reflectivity data and a background sub-frame of no light followed by continuous light, while the sensor is gated, to determine a level of background light. A color sub-frame projects continuous light, while the sensor is active. |
