DEPTH INFORMATION IMAGE ACQUISITION APPARATUS AND ELECTRONIC DEVICE

WIPO Patent Application WO/2022/016412

A1

A depth information image acquisition apparatus and an electronic device (400). The present application is simple in structure, can reduce device power consumption, and facilitates the improvement of outdoor use effect. The apparatus comprises: multiple two-dimensional optical phase modulation structures (110), each two-dimensional optical phase modulation structure (110) comprising a substrate (111) and a protrusion (112) disposed on the substrate (111), and being used for performing spatial phase modulation on an optical signal reflected by an object; and an optical sensor that is disposed below the multiple two-dimensional optical phase modulation structures (110) and comprises multiple pixel arrays (120). The multiple pixel arrays (120) correspond one-to-one to the multiple two-dimensional optical phase modulation structures (110). A pixel array (120) is used for receiving the optical signal modulated by the corresponding two-dimensional optical phase modulation structure (110). A pixel array (120) comprises multiple pixels. The intensity distribution of optical signals received by the multiple pixels is used for determining the incident angle of the optical signal incident on the corresponding two-dimensional optical phase modulation structure (110), and the incident angle is used for determining depth information of an object image.
