Abstract
A video camera specifies as a photometric area any block of a field of image to be picked up and picks up a subject to be seen by optimizing the amount of light regardless of the position where a television camera is located. The video camera comprises a solid-state image pick-up element (CCD), a display device and devices for controlling the diaphragm of a lens. In operation, the image picked up by the solid-state image pick-up element is divided into plural blocks to be displayed. Any block of these plural blocks can be specified as a photometric area. The amount of light for the photometric area is calculated and the diaphragm of the lens is controlled so that the subject can be seen by optimizing amount of light.
