Apparatus and method for extracting edges of image
Provided are an apparatus and method for more accurately extracting edge portions from an image in various conditions. The apparatus includes: a brightness calculation unit calculating a representative brightness value of the neighborhood of a current pixel; a threshold value calculation unit calculating a threshold value, based on which it is determined whether the current pixel is an edge, by using the calculated representative brightness value; a mask application unit calculating a masking value by applying a mask to an area containing at least the current pixel; and an edge determination unit determining whether the current pixel is an edge by comparing the masking value and the threshold value.
