摘要
A consecutive thin edge detection system and method for enhancing color filter array image is disclosed in the present invention. The consecutive thin edge detection system includes a consecutive thin edge detector, a color gradient estimator and a direction indicator. The consecutive thin edge detector receives a color pixel array including a plurality of color pixels and alternately sets each color pixel as a target pixel. The consecutive thin edge detector detects a difference value between a plurality of first green pixels and a plurality of second green pixels nearby a target pixel, and determines whether the target pixel comprises a consecutive thin edge feature or not according to the difference value. The plurality of first green pixels are in red pixel rows which comprises a plurality red pixels and the plurality of first green pixels, and the plurality of second green pixels are in a blue pixel row which comprises blue pixels and the plurality of second green pixels.
