Abstract

A method for processing an image signal includes evaluating an edge factor based on a characteristic of an original image signal. A gain-adjusted calibration signal is generated based on the edge factor. The original image signal and the gain-adjusted calibration signal are summed to generate a transient-improved image signal. Accordingly, an image signal transient is adaptively improved depending on edge characteristic.

Description

[0001] Cross References to Related Applications [0002] Pursuant to 35 USC §119, this application claims priority to Korean Patent Application No. 10-2006-0015314 filed in the Korean Intellectual Property Office on February 16, 2006, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to improvement of image quality, and in particular, to a method and device for processing an image signal, and a display system including the image processing device. Background technique [0004] Transient improvement for image signals increases image clarity by increasing sharpness and reducing edge transition times. When this transient improvement technique is applied to a luminance signal, the technique is called a luminance transient improvement technique. [0005] In general, this transient improvement technique makes images look sharper by reducing transition times. [0006] 1A to 1E are waveform diagrams illustrat...
