Abstract
An automatic focusing apparatus for a video camera, comprising a photographic lens, a solid state image pickup device mounted movably along the optical axis of the photographic lens, a device for moving the image pickup device along the optical axis, and a focusing operation circuit for generating a focusing signal for moving the image pickup device to the focusing point by processing the output of the image pickup device, and feeding the focusing signal to the moving means. The moving device consists of a moving coil secured to the image pickup device, and a drive circuit for driving the moving coil. The focusing operation circuit is connected to the drive circuit directly or via an automatic-manual selecting switch. The image pickup device may be split to a section for taking a picture and a section for measuring the distance from the object, and the photographic lens may be a zoom lens having no mechanism for focusing.
