Camera exposure processing method and device and intelligent terminal

Abstract

The embodiment of the invention discloses a camera exposure processing method and device and an intelligent terminal, and the method comprises the steps: detecting the brightness of a current environment through a brightness sensor, and obtaining the brightness value of the current environment; obtaining the grade of the current actual environment according to the obtained brightness value of thecurrent environment; when the grade of the current actual environment is a preset environment darkness grade, controlling to search an exposure coefficient sensitivity gain table corresponding to theenvironment darkness grade, and confirming a corresponding exposure parameter; and dynamically adjusting exposure according to the exposure parameters of the lookup table, and controlling to output anexposure picture with corresponding brightness. According to the invention, the current environment state is correctly judged by adding judgment on the brightness of the environment light, and then the current environment state enters the low-illumination exposure system to carry out more appropriate exposure control, so that the brightness in a picture is appropriate under the condition of low illumination, such as weak light or light turn-off; therefore, a user can see a picture with proper brightness under the condition of weak light or light turn-off.

Description

technical field [0001] The present invention relates to the technical field of camera image processing, in particular to a camera exposure processing method, device, and intelligent terminal. Background technique [0002] The TVs in the prior art are basically equipped with cameras, which are used in various entertainment, meeting and shooting scenes. Cameras are particularly susceptible to ambient light. Especially in low light or when the light is turned off, the camera thinks that the light is too dark when exposing, so it increases the gain of the sensor (sensor) to make the picture brighter. The brightened content on the camera is displayed on the TV, so that the screen will emit brighter Strong light causes the camera exposure system to think that the environment is too bright at this time, so the gain of the camera sensor is reduced. Repeating this action will cause problems in the automatic exposure system of the camera, resulting in bright and dark vibrations in t...

AI Technical Summary

Problems solved by technology

The invention can well solve the phenomenon that the exposure of the TV camera will repeatedly oscillate when shooting in a low-illuminance environment, and achieve the appropriate brightness of the picture when shooting in a low-illuminance environment
