Abstract
In a camera remote-controlling apparatus, the incident angle based on a remote-controlling signal issued from a specific object to be photographed is detected by a signal receiving unit and the position of the object is operated and specified. The photographing optical system is driven to vary the focal length so that the specified object may enter the photographed picture. Further, distance measuring information for the object is detected by a distance measuring part, the photographing optical system is focused and, at the same time, light measuring information for the luminance of the same specified object is detected by, a light measuring part to control the exposure.
