Abstract

PURPOSE:To output an image pickup signal whose level is made proper as to not only a main subject but also a background at the time of a reverse light, by generating the image element synthesizing control signal of an (n) sec accumulating image and an (m) sec accumulat ing image at the time of a second image pickup mode from the (n) sec accumulating image. CONSTITUTION:In an image pickup device to be equipped with a first image pickup mode to generate a video signal in repeating the light accumulation of (n) sec and the second image pickup mode to alternately execute the light accumulation of (n) sec and the accumula tion of (m)(<n) sec, to synthesize the (n) sec accumulating image and the (m) sec accumulating image and to generate the video signal of one screen, the switching signals of the first and second image pickup modes and the image element synthesizing control signal of the (n) sec accumulating image and the (m) sec accumulating image at the time of the second image pickup mode are generated out of the (n) sec accumulating image. Consequently, the first image pickup mode without the deterioration of a time resolution is basically selected, and an image element synthesization by the second image pickup mode can be made into one having as little deterioration of the time resolution as possible. Thus, not only the main object but also the background can be photographed in a proper exposure at the time of the reverse light, and a dynamic range can be practically extended.
