Abstract
Abstract A high-speed video camera having a plurality of solid-state black-and-white image pickup elements to which same scene is projected, respectively, each of said image pickup elements consisting of a plurality of photoelectric conversion element rows, some of which are scanned at the same time. A high-speed color video camera having a plurality of solid-state black-and-white image pickup elements and a plurality of solid-state color image pickup elements to which same scene is projected, respectively, each of image pickup elements consisting of a plurality of photoelectric conversion element rows, some of which in the solid-state black-and-white image pickup elements are scanned at the same time so that a luminance signal component is obtained therefrom, and some of which in the solid-state color image pickup elements are scanned at the same time so that a color signal component is obtained therefrom. The luminance signal component and the color signal component are synthesized to form a color image.
