Title
(EN) Image brightness enhancement method and apparatus
(ZH) 一种图像亮度增强方法及装置
Abstract
(EN)
The invention discloses an image brightness enhancement method and apparatus for solving the problem in the prior art that after supplementary infrared light is irradiated, the color of a video imagecannot be restored, such that the collected video image becomes a black-and-white image. The method comprises the following steps: a camera device controls the opening or closing of a fill-in light according to a received control single; when controlling the closing of the fill-in light, the camera device controls a light sensing unit to collect color image data containing color information; whencontrolling the opening of the fill-in light, the camera device controls the light sensing unit to collect brightness image data containing brightness information; and the camera device synthesizes the color image data with the brightness image data to generate image comprising the color information and the brightness information.
