An apparatus for detecting a hot pixel and an apparatus for detecting and correcting a bad pixel regarding a hot pixel. The apparatus for detecting a hot pixel has a pre-application unit for performing a gain operation or gamma correction on a pixel of an inputted image, a hot pixel detection unit for determining whether a pixel inputted from the pre-application unit is a hot pixel by comparing the pixel with a neighboring pixel, and a flag generation unit for generating a hot pixel flag in case the hot pixel detection unit detects a hot pixel. With the present invention, the spread of noise can be prevented in advance, significantly reducing the distortion of an image and improving the quality of a processed image. |
