Abstract
An image processing device includes a line gain calculator, a line gain corrector, and a gain adjustor. The line gain calculator calculates an absolute value of Gradient and an absolute value of Laplacian of the input image, and calculates a line gain based on the absolute value of the Gradient and the absolute value of the Laplacian. The line gain corrector calculates a blend coefficient based on the input image and the line gain and to correct the line gain based on the blend coefficient. The gain adjuster processes the input image based on the corrected line gain to generate an output image.
