Abstract
A blue signal B, a green signal G, and a red signal R are obtained by imagining a subject illuminated with white light W using a color CCD. Based on these signals B, G, and R, a normal light image in which a wavelength component of a visible light region is included is generated. Based on the signals B, G, and R, a brightness signal I ((B+G+R)/3) showing the average brightness of the subject is generated. A pixel region exceeding the fixed threshold value Thof the brightness signal I is extracted as a superficial microstructure P, such as a pit pattern. A microstructure enhancement imageis generated by combining the normal light image with a superficial microstructure imageobtained by extracting the superficial microstructure P. The generated microstructure and blood vessel enhancement imageis displayed on a monitor
