Document Type and Number:
Japanese Patent JP3327614
Kind Code:
B2
Abstract:
PURPOSE:To provide an image pickup device which can appropriately correction- process a synthesized video signal without being affected by the chroma and the luminance of a specified area at the time of dividing an object into plural areas, photographing them, synthesizing video signals in the respective areas and generating a synthesized video. CONSTITUTION:An image pickup means consisting of an optical lens 1 and an image pickup element 2 photographs the respective areas of the object, which are divided into plural pieces. The video signals of the respective areas, which are thus photographed, are stored in a memory 6 through an AD converter 5 and are inputted to an integrator 15. A system controller 13 generates control voltage executing correction based on the image characteristics of all the video signals in the respective areas in accordance with the integral values of the images in all the areas from the integrator 15. DSP 8 appropriately corrects the white balance and the luminance of the synthesized video signals which are read from the memory 6 based on the control voltage, and the photographed image of high quality can be obtained.
