Depth camera for mobile communication devices

Abstract

A depth camera device is provided for a mobile communication device. The depth camera device includes: an infrared transmitter module configured to emit infrared light in a first wavelength range, and an infrared camera module configured to acquire image light and Generating a depth image, the infrared camera module further includes: an imaging lens configured to capture image light, and a first anti-reflection coating is formed on a surface of the imaging lens, the first anti-reflection coating is used to enhance the first wavelength range a transmitted intensity of light; and a black-and-white image sensor configured to be optically aligned with the imaging lens and receive image light directly from the imaging lens without passing through any filter, the black-and-white image sensor being responsive to receiving the image light from the imaging lens. The imaging lens directly receives the full-band light of the image and generates electrical signals. The depth camera device provided by the present invention can improve the sensitivity performance of the image sensor to infrared light, save power consumption, speed up data acquisition, and simplify the processing process.

Description

technical field [0001] The present invention relates to a depth camera device, more specifically, to a depth camera device for mobile communication equipment. Background technique [0002] Nowadays, machine vision has quietly transferred from industrial control to the consumer electronics market. The demand for miniaturization and low power consumption has led to the fact that in the selection of hardware devices, it is usually impossible to choose a laser transmitter with high power consumption to meet the user's requirements for structured light intensity at a distance. Clear projection in the distance; it is also impossible to integrate a camera with a large-size photosensitive chip to meet higher photosensitive performance, larger dynamic range, and finer grayscale characteristics, so that the resolution accuracy under the hardware conditions of the industrial control field cannot be achieved. However, in order to achieve a good user experience, the application scenarios...
