Dynamic localized contrast enhancement method for image and computer readable medium of the same

A dynamic localized contrast enhancement method for images applied to a display unit which is receiving a plurality of image frames that are formed by a plurality of pixels with color feature values comprising the following steps:

• step one:
• scanning the image frame dynamically by a window whose size is smaller than that of the image frame;
• step two:
• receiving color feature values of pixels in the window;
• step three:
• generating a distribution histogram according to the color feature values of the pixels in the window;
• the distribution histogram shows a relationship between the color feature value and a corresponding count of the pixels while the count represents the amount of the pixels with the color feature value in the window;
• step four:
• performing an operation by contrast stretching according to the distribution histogram so as to adjust image contrast in the window.
