Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0032] figure 1 It is a schematic flowchart of the image processing method based on brightness value adjustment in the present invention.

[0033] like figure 1 As shown, the image processing method based on brightness value adjustment includes the following steps:

[0034] S1, acquiring the brightness value of each square in the image to be captured;

[0035] S2. For a square that is completely filled by the object t...

Abstract

The invention discloses a method and system for picture processing based on brightness value adjustment. The method comprises the steps of obtaining a brightness value of each square of a to-be-photographed picture; completely filling the to-be-photographed picture; for the square which is completely filled with a to-be-photographed object and has the brightness value of the completely filled part larger than a preset value, lowering the brightness value of the square; and outputting the to-be-photographed picture with the reduced brightness value. According to the method and system for picture processing based on brightness value adjustment, the square is taken as a unit to detect the brightness value of the to-be-photographed picture, and the square with the brightness value larger than the preset value is subjected to brightness value reduction processing.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and system based on reduced brightness values. Background technique [0002] At present, when using a video camera to take pictures, it is often encountered that the light in the scene is relatively dark. In order to be able to take pictures in the case of relatively dark light, the camera will have a built-in flash for use at night or when the light is relatively dark. , to assist in taking pictures. However, this method of taking pictures will cause the picture to be overexposed, resulting in unclear details of the objects in the picture. Contents of the invention [0003] The object of the present invention is to provide a picture processing method and system for detecting the brightness value of a picture to be taken in units of squares, and reducing the brightness value of the squares whose brightness value is greater than a pre...
