Abstract
A device for generating depth information includes a plurality of light sources, an image capture unit, a control unit, and a processing unit. Each light source of the plurality of light sources emits a corresponding intensity light. The control unit controls the each light source of the plurality of light sources to emit the corresponding intensity light in turn, and controls the image capture unit to capture a plurality of images corresponding to the plurality of light sources. The processing unit generates a plurality of depth information corresponding to the plurality of light sources according to the plurality of images corresponding to the plurality of light sources and a background image after the image capture unit captures the plurality of images corresponding to the plurality of light sources and the background image.
