Abstract

PURPOSE:To save a space and to simplify a circuit, by disposing an objective lens in front of a unit and a diffusion plate around the objective lens, housing a photodetector for photometry in the focus-position of the lens and a photodetector for white balance correction to the rear of the diffusion plate all integrally in the unit. CONSTITUTION:In front of the sensor unit 21, the objective lens 23 is fixed, and around this lens 23, the opal white diffusion plate 24 in ring shape is fixed on the periphery of the lens 23. To the rear of the sensor unit 21, a substrate 25 is fixed, and in the focus-position of the objective lens 23 on top of the substrate 25, the CdS(photodetector for photometry) 26 is fixed, further, on the substrate 25 of the outer side part S2 of a barrel 22, photodiodes 28r, 28g, 28b respectively having color transmitting filters 27r, 27g, 27b of three primary colors of red, green, red are arranged on a circle having a radius of fixed length from CdS26 with equal intervals. In such a way, the photodetector for correcting white balance and the photodetector for controlling automatic exposure can be arranged on the same substrate.
