Histogram mapping method for removing image flicker

The invention discloses a histogram mapping method for removing image flicker. The method comprises steps of first, obtaining a histogram of a current frame of image according to a histogram of a previous frame of image; second, enhancing the histogram of the current frame of image, obtaining a histogram mapping table of the current frame of image, and outputting a real-time image according to thehistogram mapping table of the current frame of image. Compared with the existing technology of removing image flicker, the method processes the histogram of the image directly, and can respond to and process a change of an image background timely, thereby having better effect of removing flicker; in addition, the method considers correlation of two adjacent frames of image, thereby improving image display quality and being highly reliable. The method has a more concise processing process, has small calculation amount, and is easy to realize through hardware. 本发明公开了一种去除图像闪烁直方图映射方法，该方法包括：步骤一、根据前一帧图像的直方图，得到当前帧图像的直方图；步骤
