Camera module

Abstract

An embodiment of the invention discloses a camera module, which comprises a lens, an RGB image sensor, an infrared image sensor, a first lens and a second lens, wherein the numbers of the lens, the number of the RGB image sensors and the number of the infrared image sensors are the same and is in one-to-one correspondence; the first lens is used for dividing incident light into a first light ray and a second light ray, and the first light ray is a visible light ray an is irradiated to the RGB image sensor for light sensitive imaging in the daytime; the second light ray is an infrared light rayand is reflected to the infrared image sensor through the second lens for imaging at night; an optical path difference between an optical path of the first light ray incident to the RGB image sensorand an optical path of the second light ray incident to the infrared image sensor meets a preset time condition; and the RGB image sensor is used for judging whether a current shooting environment isin the daytime or at night according to the brightness in the external environment. According to the camera module, a daytime monitoring mode and a night monitoring mode can be switched, the shootingquality of the camera module is improved, and high-definition and high-quality pictures can be obtained.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of photographic equipment, in particular to a camera module. Background technique [0002] As users have higher and higher requirements for the quality of imaging pictures, the continuous development of camera and photography equipment technology is required to obtain high-quality and high-definition pictures. [0003] In the prior art, the monitoring camera module achieves daytime and night monitoring mode switching by setting a photosensitive device and an IR switcher in the camera module. The photosensitive chip is an image sensor, and the IR switcher includes two filters and a power switch. Module, the filter is an infrared cut-off or absorption filter (infrared filter) and a full-transmission spectral filter (ordinary filter), and the power module can be electromagnetic, motor or other power source. [0004] The camera module needs to shoot in two scenarios, day and night, but in ...

AI Technical Summary

Problems solved by technology

[0004] The camera module needs to shoot in two scenarios, day and night, but in the design, it is impossible to take into account the shooting effects of both, resulting in only good shooting effects in one scene, and shooting in another scene. image quality is not high
