  • Patent number: 9601060
    Abstract: The disclosure of the present invention provides an image processing method and apparatus. The method comprises acquiring a single picture image displayed on a display panel; determining an average value of each area relating to a display parameter, after the acquired single picture image is divided into a plurality of areas according to a preset regulation; determining differences between average values of respective two adjacent areas, and determining a uniformity of the single picture image displayed on the display panel in accordance with a relationship between each difference and a threshold of a resolvable picture uniformity by an human eye; adjusting the difference between the average values of the respective two adjacent areas to be not greater than the threshold of the resolvable picture uniformity by the human eye, when determining the single picture image displayed on the display panel to be not uniform.
