Problems solved by technology

In the existing technology, the brightness adjustment of the camera needs to be manually performed, especially the daytime shooting mode and the night shooting mode need to be switched manually, otherwise the captured picture cannot meet the normal application requirements
If the brightness is extremely low at night, if the user does not manually set the camera to the night shooting mode, the photos taken will not meet the needs of use
Especially in some occasions where the brightness of the external environment changes rapidly, it will take a certain amount of time to manually switch between the daytime shooting mode and the nighttime shooting mode, resulting in missing the shot you want to capture, causing regret and inconvenience to the shooting

Embodiment 2

[0033] This embodiment describes in detail the implementation method of the camera brightness adjustment device described in the first embodiment.

[0034] The methods include:

[0035] S1 is a step for obtaining the current ambient light intensity value (Als_level);

[0036] S2 is a step of selecting a corresponding camera brightness parameter target value (Als_value) according to the current ambient light intensity value (Als_level).

[0037] S3 is used to control the camera according to the camera brightness parameter target value (Als_value), so that the current value of the camera brightness parameter is consistent with the camera brightness parameter target value (Als_value). In this way, the brightness of the camera is automatically adjusted to a state where high-quality images can be captured in the current environment.

[0038] The steps of S1 for obtaining the current ambient light intensity value (Als_level) include:

[0039] S111 camera captures and outputs imag...

Abstract

The invention discloses a camera brightness regulating device and an implementation method thereof. The implementation method includes: S1, acquiring current environmental light intensity; S2, selecting a corresponding target value of camera brightness parameter according to the environmental light intensity; and S3, controlling a camera according to the target value of camera brightness parameter so as to enable the current value of camera brightness parameter to be consistent to the target value of camera brightness parameter. The camera brightness regulating device and the implementation method thereof allow camera brightness and shooting mode to be automatically adjusted according to environmental light conditions with no need of manual setting by users, allow the users to snapshot in a short time, and allow higher quality frames to be shot.

Description

technical field [0001] The invention relates to the field of electronic technology and the field of light sensing, in particular to a camera brightness adjustment device. Background technique [0002] With the rapid development of electronic technology and the increasing needs of users, people have more and more applications for cameras in daily life, such as videophones, photographs, video cameras, etc. Cameras that can shoot high-quality images have become an important part of this field. one of the directions of development. In the prior art, the brightness adjustment of the camera needs to be manually performed, especially the switching between the daytime shooting mode and the nighttime shooting mode requires manual operation, otherwise the captured images cannot meet normal application requirements. For example, at night when the brightness is extremely low, if the user does not manually set the camera to the night shooting mode, the photos taken will not meet the nee...
