Abstract

In a red-eye detection/retouch apparatus, a first area extraction unit receives an image including a red eye and a signal representing a small area including the red eye and designated by a user and extracts a first area including the red eye. A first pixel selection unit detects the reddest pixel from the first area and outputs coordinate values and color information of the pixel. A determination unit determines whether the other red eye is present on the basis of the signal representing the small area and the coordinate values of the reddest pixel. The determination unit outputs an instruction signal for extracting a second area where the other red eye is present upon determining that the other red eye is present. A second area extraction unit receives the instruction signal and extracts the second area from the first area. A second pixel selection unit detects the reddest pixel from the second area and outputs coordinate values and color information of the pixel. An area expansion unit receives the coordinate values and color information of the pixels and the first area, detects a red-eye area by area expansion, and outputs the red-eye area. An image synthesis unit receives the red-eye area and the image including the red eye and outputs an image whose red-eye area has been corrected to a natural pupil color.
