A method of detecting a region having a specific shape in a camera is provided. The method includes processing input image data in a camera and detecting the region having the specific shape. The method includes calculating gradation differences between a central pixel and respective peripheral pixels in each of local regions of an image frame, comparing an average gradation difference with each of the gradation differences and obtaining local gradient pattern (LGP) values based on a comparison result in each of the local regions, and detecting the region having the specific shape from the image frame using the LGP values obtained from the respective local regions.
