Title:
EXTRACTOR FOR FEATURE OF SKIN SURFACE SHAPE BASED ON RESTORATION OF THREE-DIMENSIONAL SHAPE FROM IMAGE PERTAINING TO SKIN SURFACE
Document Type and Number:
Japanese Patent JP3236362
Kind Code:
B2
Abstract:
PURPOSE: To enable accurate extraction of features of a skin surface by enabling the restoration of a three-dimensional shape of the skin surface.
CONSTITUTION: A CPU8 controls a switch 6 through a bus 7 and a replica surface is lighted sequentially by a first light source 2A, a second light source 2B and a third light source 2C sequentially to pick up three image data to be obtained from an magnification optical system 3, a camera 4 and an A/D converter 5 into a memory 9 through the bus 7 sequentially corresponding to respective lighting operations. The CPU8 calculates a gradient of the replica surface 1 at the positions of pixels of an image of the replica surface from a lightness value of the pixels of the three image data thereby extracting feature parameters pertaining to a three-dimensional shape of a skin surface based on the gradient.
