AN IMAGE PROCESSING METHOD AND APPARAUTS

The present invention discloses an image processing method and apparatus. The method comprises the steps of: counting the number of pixels distributing in different brightness values in the target image; determining an initial central brightness value that maximum numbers of pixels have and determining an average brightness value of the target image; and adjusting a quantity distribution of the pixels in the target image at different brightness values, so as to make a new central brightness values that maximum number of pixels have closer to the average brightness value than the initial central brightness value, and to expand a range of pixel brightness values having preset brightness thresholds in which the new central brightness value is included. The present invention discloses an image processing method and apparatus, which enlarges the range around the central brightness value and adjusts the brightness distribution of the image to enhance the details of the image.
