A TV camera comprises an objective lens, a color resolving prism, image pickup devices provided in opposed relationship with the respective exit surfaces of the color resolving prism, and a bias light device. This TV camera is characterized by a novel, small color resolving prism. The color resolving prism comprises four sub-prisms each having a refractive index of 1.6 or higher. The vertical angles of the respective sub-prisms are:23.3.degree..ltoreq..theta..sub.1 .ltoreq.25.8.degree.2.degree..ltoreq..theta..sub.2 .ltoreq.13.degree.28.5.degree..ltoreq..theta..sub.3 .ltoreq.37.7.degree.13.9.degree..ltoreq..theta..sub.4 .ltoreq.18.2.degree.
摘要:
A television camera is provided with a color resolving optical system for color resolution and for forming a plurality of optical paths, the color resolving optical system having at least one dichroic film, a plurality of image pick-up tubes disposed on the optical paths for receiving the image of an object to be photographed, and an illuminating device emitting a plurality of illuminating lights of a predetermined wavelength range and provided with an adjuster for adjusting the quantity of light of at least one of said illuminating lights. The wavelength band width of said illuminating lights is narrower than the wavelength band width color-resolved by the color resolving optical system and/or the positions at which said illuminating lights are emitted differ from one another, whereby color shading of the image pick-up tubes is eliminated.

A television camera provided with a biased light source device disposed outside of the light path extending from the picture taking lens to the image pickup surface. The biased light source device has an elongated shape and such illumination distribution that the intensity of light emitted from the device is gradually reduced toward the central portion from the marginal portions in the longitudinal direction so that the image pickup surface may be uniformly illuminated with respect to the direction corresponding to the longitudinal direction of the biased light source device.
