Method and system for eliminating camera flare

Abstract

A method and system for eliminating camera flare, the method comprising: 1. sequentially acquiring images A and B of the two frames before and after; 2. acquiring the bright regions A and B in the two frames of images A and B before and after; 3. counting the brightness The ratio of the number of pixels with a luminance value of 18% in the middle area A and B. When the statistical number ratio reaches the preset threshold, it is determined that the image data is valid; 4. Pixels that are valid for the bright area A and B Perform the weighted average calculation of the brightness value to obtain the weighted average value; if the weighted average value of the bright area A and B is less than the preset threshold, it is judged that the frame rates of the images A and B of the two frames before and after are consistent, and the judgment is completed and the camera mode is entered. Otherwise, it is determined that the frame rates of the two frames of images A and B are inconsistent, and the frame rate of the light is obtained again, and the next step is performed; 5. Adjust the frame rate of the screen display according to the frame rate of the light. According to the invention, when mobile terminals such as mobile phones take pictures of lights, light spots that shake images will not appear in the preview.

Description

Technical field [0001] The present invention relates to camera photography technology, in particular to a method and system for eliminating camera spots. Background technique [0002] A camera is abbreviated as a camera, which is a device that uses the principle of optical imaging to form images and uses negatives to record the images. Many devices that can record images have the characteristics of a camera. Medical imaging equipment, astronomical observation equipment, etc. A camera is an optical device used for photography. After the light reflected by the subject is focused by the camera lens (scenario objective lens) and the shutter that controls the exposure, the subject forms a latent image on the photosensitive material in the dark box, and is processed (i.e., developed, fixed) to form a permanent image This technique is called photography. Divided into general photography and professional photography. [0003] However, in the prior art, there is a flare problem during ...

Problems solved by technology

[0003] However, in the existing technology, there is a problem of light spots in the process of taking pictures, that is, the flick problem. The so-called camera flick problem has actually been troubled by a screen display problem offline. The specific scene is on the counter, because the quality of fluorescent lamps in various places is different. , and the influence of the local voltage, when the camera is turned on to preview the photo taken against the light, there will be obvious flickering on the screen, which is caused by the difference between the frame rate of the light display and the standard display frame rate, and the domestic standard is generally 50HZ , the actual scene is slightly higher or lower will cause the above phenomenon
