Abstract:
1. An image compensating method, comprising: calculating a representative luminance for each pixel of an image based on a luminance of a corresponding pixel and luminances of pixels positioned in a vicinity of the corresponding pixel; determining a compensation luminance ratio using the calculated representative luminance; increasing an output luminance of at least the corresponding pixel based on the compensation luminance ratio, wherein, the compensation luminance ratio decreases as the representative luminance increases, and wherein, when calculating the representative luminance, the representative luminance is calculated by calculating luminance differences between the corresponding pixel and the pixels positioned in the vicinity of the corresponding pixel, classifying the luminance differences into two groups according to whether each luminance difference is greater than a threshold luminance, and averaging luminances of pixels in a group, of the two groups, having a greatest number of pixels.
