Abstract: An image sensing apparatus having a display device mounted rotatable about an axis on a side of the image sensing apparatus for displaying a sensed image. When the display device is folded up by the side of the image sensing apparatus, a mirror reflects an image displayed on the display device toward a finder, so that the displayed image can be seen though the finder.

Abstract: A video camera (31) has a built-in video light (32) for photography in the dark. The built-in video light (32) has heat dissipation holes (32f1) capable of opening and closing, and a heat dissipation control for controlling opening and closing of the heat dissipation holes according to the stowage operation by a stowage control.

Abstract: In an image pickup system such as a video camera having an adjusting circuit for adjusting a white balance in a color image signal, each interchangeable lens has a device for providing information on the spectral characteristic inherent in the lens. In one embodiment, a microcomputer is provided for processing the information on the spectral characteristic inherent in the lens. When the lens is mounted on the camera body incorporating the adjusting circuit, the information on the spectral characteristic of the lens is transmitted into the camera body by a mechanical arm whose length is representative of the spectral characteristic of the lens, thereby enabling the adjusting means to make a proper adjustment of the white balance for each lens having a different predetermined spectral characteristic.
