Flash lamp control method and terminal

Abstract

The embodiment of the present invention discloses a flash lamp control method and a terminal. The method comprises the steps of acquiring light luminance values in all sub-image regions contained in an image displayed in the imaging region of the terminal; for each sub-image region, judging whether the acquired light luminance value of the sub-image region is within the range from a preset minimum luminance value to a preset maximum luminance value or not; on the premise that the acquired light luminance value of the sub-image region is larger than the preset maximum luminance value, controlling a flash lamp corresponding to the above sub-image region to be switched off, wherein the sub-image regions and flash lamps are in one-to-one correspondence manner; on the premise that the acquired light luminance value of the sub-image region is smaller than the preset minimum luminance value, regulating the light luminance value of the flash lamp corresponding to the above sub-image region to be a target luminance value, wherein the target luminance value is the difference value between a standard exposure value and the light luminance value of the sub-image region, and the standard exposure value is between the preset minimum luminance value and the preset maximum luminance value. According to the embodiments of the invention, the shooting effect of the terminal is improved during the shooting process. Meanwhile, the shooting experience of users is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a flashlight control method and a terminal. Background technique [0002] With the rapid development of terminal technology, there are more and more mobile terminals with a shooting function, such as digital cameras, mobile phones, and tablet computers. In addition, most of the mobile terminals capable of photographing are equipped with a camera as well as a flashlight, which can improve the quality of photos taken in low-light environments. However, in practice, it has been found that the brightness and darkness of the scenes shown in the camera will vary during shooting. Some of the scenes may be under strong light, while others are under low light. At this time, when using the same flash for supplementary light, It is easy to cause problems such as over-exposure of some scenes, or under-exposure of some scenes, so that the quality of the captured photos is reduced, ...

However, in practice, it has been found that the brightness and darkness of the scenes shown in the camera will vary during shooting. Some of the scenes may be under strong light, while others are under low light. At this time, when using the same flash for supplementary light, It is easy to cause problems such as overexposure of some scenes, or underexposure of some scenes, which will reduce the quality of the photos taken and seriously affect the shooting effect
