Kind Code:
B2
Abstract:
PURPOSE:To improve the quantity of lighting by using at least one of >=2 colors of mixed light for lighting light illuminating an object in face sequential. CONSTITUTION:A light source lamp 52 is lighted by a white light such as a xenon lamp and has a luminous spectral distribution close to radiation of black body. A rotary filter 54 consists of three sectorial color transmission filters 54R, 54Y, 54B. The object 51 is lighted sequentially (e.g., R, Y, B, R) by light of a wavelength through a color transmission filter interposed between a lens 53 and an incident end face of a light guide 48 and the light is formed on an image pickup face of a solid-state image pickup element 47 by a CCD or the like. Thus, timewise identical R, G, B information is obtained, the deflection of image of the luminance signal is decreased, the resolution of a moving picture is improved.
