Abstract
An electronic still video camera wherein a pre-exposure period is utilized to generate control signals to control both exposure and color balance includes a photoelectric converter for producing an electrical signal corresponding to a received image. Exposure structure is provided for exposing the converter to the image, the amount of radiation admitted by the exposure structure being controllable. Color adjusting circuitry is provided for electrically altering the balance of different colors in the picture to be taken. Control circuitry is provided for controlling the exposure structure to provide a first exposure, and for deriving, from the output of the photoelectric converter corresponding to the first exposure, integrated values which are used to correct both an exposure period and the color balance in a subsequent picture-taking second exposure.
