Image pickup device

Abstract

Abstract PURPOSE:To obtain an appropriate white balance by isolating luminous energy from peripheral light and that from flashing light so as to measure them, distributing an amplification gain due to the peripheral light and that due to the flashing light by the rate of two kinds of luminous energy and adjusting the white balance. CONSTITUTION:The titled device is provided with a means storing data on the color and temperature of a light flashing means, a light measuring means 11 which isolates and measures light intensity due to the peripheral light and that due to the light flashing means, a color measuring circuit 12 measuring the color and temperature caused by the peripheral light, variable gain amplifiers 5 and 6 controlling the balance of chrominance components from an image pickup element 4, and an arithmetic control circuit 10 which controls the light intensity that the light measuring circuit 11 measures and the color and temperature that the color measuring circuit 12 does and the gains of amplifiers 5 and 6 according to the data on the color and temperature. Thus the white balance taking into consideration of the colors and temperatures caused by the peripheral light and the flashing light can be obtained.
