The invention relates to the technical field of image processing, in particular to a processing method and system capable of eliminating the influence of light spots on the centroid and the gravity center of an image, and is characterized in that when the image is displayed, the image resolution of each frame of picture is m * n, each column pulse represents the refreshing of a pixel point, and the image resolution is m * n; if a counter is used for counting column pulses, a count value is used for representing any pixel point on a display, and when an image is displayed, if a light spot fault point occurs, the position of the pixel point and the refreshing time are determined according to the count value. 本发明涉及图像处理技术领域，具体的说是一种可消除光斑对图像形心及重心影响的处理方法及系统，其特征在于，当图像显示时，每一帧画面的图像分辨率为m×n，每一个列脉冲都代表一个像素点的刷新，若使用一个计数器对列脉冲进行计数，就用这个计数值来表示显示器上的任意一个像素点，在图像显示时，若出现光斑故障点，则按照计数值来确定这个像素点的位置及刷新的时间。
