Abstract
The television camera of a video telephone set can easily be focused on the image of an object, such as a sheet of paper, through an inexpensive focusing apparatus. An indication corresponding to the size of the sheet is displayed on a display unit. The size of the displayed indication is determined depending on the distance, as detected by a zoomed distance detector, by which the lens of the television camera is zoomed. The position of the television camera is moved with respect to the object until the edges of the sheet are aligned with the indication displayed on the display screen of the display unit. When the edges of the sheet are aligned with the displayed indication, the television camera is sharply focused on the displayed image of the object. The size of the displayed indication, which indicates the actual size of the sheet, is determined based on an inputted sheet size and the detected distance by which the lens is zoomed. The television camera can thus be focused on the displayed image with ease.
