Abstract
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.
