Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] In this embodiment, a brightness compensation method is provided, figure 1 is a flowchart of a brightness compensation method according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0026] Step S102, dividing the shooting picture into a predetermined number of blocks;

[0027] Step S104, determining the depth of field information of the image in each block;

[0028] Step S106, performing block-by-block brightness compensation on the above picture according to the determined depth of field information.

[0029] Through the above steps, the brightness compensation is performed in sub-blocks according to the depth of field in...

Abstract

The invention provides a method and a device for brightness compensation. The method comprises steps: a shooting picture is divided into a predetermined number of blocks; the depth information of an image in each block is determined; and according to the determined depth information, block brightness compensation is carried out on the picture. Thus, the problem of poor shooting quality existing in a related technology is solved, and effects of improving the shooting quality are further achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a brightness compensation method and device. Background technique [0002] A flash is a photographic accessory that can emit strong light in a short period of time. It is mostly used for instant lighting in places with low light, and it is also used for partial fill light of the subject in places with bright light. Small size, safe to use, easy to carry, stable performance. [0003] With the popularity of smart terminals, there are more and more scenes where people use flashlights to assist in taking pictures at night. The following uses mobile phones as an example to illustrate. The flashlight of the mobile phone in the related art is limited by the process and volume, so it is easy to appear bright in the near area and dark in the distance. The center is bright and the four corners are dark, and in the related art, the brightness of the flash cannot be compensated, which l...
