Patent abstract
A plurality of distance measuring points in a picture can be correctly and rapidly focused on. Images at a plurality of distance measuring points in the picture can be detected through a photographing lens by means of an image pickup element. These detected distance measuring points can be displayed on a monitor screen. Finally, a photographing lens can be controlled with respect to the displayed distance measuring points so as to cause the output from the image pickup element to reach its highest contrast.
