Abstract
Disclosed are an apparatus and a method for detection of foreign substances in a depth sensing system. In one embodiment, a depth sensing device includes a light source to emit light, an image sensor and a processor. The image sensor receives through an optical component the light reflected by environment of the depth sensing device. The image sensor further generates a depth map including a plurality of pixel values corresponding to distances between the depth sensing device and the environment. The processor detects a blurred portion of the depth map due to a presence of a foreign substance on the optical component. The processor may further cause outputting a user alert of the presence of the foreign substance on the optical component.
