摘要: The invention discloses a method for determining nonuniform-brightness pixel points in display screen. comprises the following steps: respectively obtaining brightness value of each point an image output by screen to form initial matrix, and dividing into plurality set areas; performing frequency domain filtering processing on matrix obtain background matrix; carrying out difference operation counting with between greater than zero quantity smaller or ad area According screen, influences are eliminated through subtraction from can be quite accurately directly obtained.
