| Abstract | ||
| In this research we study the effect of the light distribution on the quality of captured images under different amount of lightness conditions then enhancing the captured images by the imaging system using an adaptive histogram equalization method and Lee method depending on the space YIQ depending on lightness component where use the reverse of this space to the basic RGB color space, then corrected using the mathematical model based on human vision system. The results were analyzed and compute the quality of the enhancement images by using various statistical criteria based on the mean and standard deviation. Adaptive histogram equalization technique gives a high quality for the enhanced images for different lightness conditions. | ||
