Embodiment Construction

[0055] In order to make the purpose, technical solutions and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings.

[0056]Example embodiments of the present application provides a method of compensating brightness of an image, the method may be implemented by the terminal. Wherein, the terminal may be a desktop, laptop, tablet, etc.. The method may be performed for image processing with the following characteristics: an image having a high luminance region, the luminance and the greater the smaller the distance to the area in the image. Such an image may be formed in a variety of situations. For example, since the optical properties of the camera lens, which will capture a wide angle image may have this feature, the image is bright center region, the smaller the farther the image brightness region. As another example, since the light irradiated vertically to a portion of the object, th...

Abstract

The invention discloses an image brightness compensation method and device and belongs to the field of image processing. The method comprises steps of in a target image, a highlight center point meeting a preset highlight condition being determined; determining a highlight area taking the highlight central point as the center in the target image; and performing brightness positive gain compensation on the image outside the highlight area in the target image, and performing brightness negative gain compensation on the image in the highlight area. By adopting the method, the image can be compensated, so details of the image cannot be lost due to over-brightness or over-darkness.

Description

Technical field [0001] The present application relates to the field of image processing, and more particularly to a method and apparatus for image brightness compensation. Background technique [0002] When image capture is performed in some scenes, it may be large due to environmental issues, resulting in bright and dark contrast on the image. For example, in the operating room, you should take a camera to shoot, and the image corresponding to the portable light of the moving light will be high, and the rest is relatively dim. Such an image may be detailed, part of the loss may cause loss details due to overlooking. Inventive content [0003] In order to solve the problem of related art, the present application provides a method and apparatus for image brightness compensation. The technical solution is as follows: [0004] In the first aspect, a method of image brightness compensation is provided, the method comprising: [0005] In the target image, it is determined that the hi...
