Claim One:
1. A wrinkle detection apparatus comprising: a first threshold processor adapted to detect one or more first edge areas included in an image of skin, and adapted for comparing a gradient value that indicates a degree of change in pixel values in the image with a first threshold, each of the one or more first edge areas being a continuous area in the image where the gradient value is larger than the first threshold; a second threshold processor adapted to detect one or more second edge areas included in the image, and adapted for comparing the gradient value with a second threshold that is larger than the first threshold, each of the one or more second edges areas being another continuous area in the image where the gradient value is larger than the second threshold; and an edge selection processor adapted for determining at least one first edge area from among the one or more first edge areas as a wrinkle area in the image, the at least one first edge area partially overlapping with at least one of the one or more second edge areas.
