Shooting control method for terminal, shooting control device for terminal and terminal

Abstract

The invention provides a shooting control method for a terminal, a shooting control device for the terminal and the terminal. The shooting control method for the terminal comprises the following steps of detecting current ambient brightness of the terminal through a ray sensor of the terminal when a preview image is collected by a front camera of the terminal; counting a brightness histogram of the preview image if detecting that the current ambient brightness is greater than preset ambient brightness; computing the current backlight degree of the terminal according to the brightness histogram; and deciding whether to open a shooting function of a high dynamic range image of the terminal according to the current backlight degree. When the front camera is utilized to shoot, the technical scheme of the invention can accurately and quickly determine whether the terminal is under the backlight environment, so that the quality of an image shot under the backlight environment is improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, and in particular, to a terminal shooting control method, a terminal shooting control device, and a terminal. Background technique [0002] Currently, more and more electronic devices have a camera function. For example, digital cameras are mostly integrated in notebook computers, digital cameras are mostly integrated in personal digital assistants (PDA, Personal Digital Assistant, personal digital assistants) and smart phones, and digital cameras are also integrated in tablet computers. Can be used for taking pictures. [0003] When shooting with electronic equipment, it is inevitable to encounter the problems of backlight scene shooting and non-backlight scene shooting. In the case of shooting against the light, the background part is often too bright and the real object of interest, that is, the subject part is too dark. However, the existing technical solutions have the following...

AI Technical Summary

Problems solved by technology

[0004] 1. There is no backlight detection method for the front camera, which cannot meet the user's needs for enhanced backlight scene detection when using the front camera to take pictures;

[0005] 2. Compared with the rear front camera, the cost of the front camera is lower and the quality is poorer, so the brightness information collected by the front camera is sometimes inaccurate, which is not conducive to the transplantation of the existing backlight detection algorithm;

[0006] 3. In the prior art, the preview image of each frame is analyzed and processed, which is easy to increase the complexity of the algorithm, and at the critical point of backlight and non-backlight scenes, the detection results are prone to frequent jumps;

[0007] 4. The practicability and user experience of the existing technical solutions are poor
