Abstract
PURPOSE: To make possible displaying of the direction of focus deviation by disposing photoelectric transducers with the intended focal plane in-between.
CONSTITUTION: Photoelectric transducers 3, 4 are disposed for the intended focal plane 5' of a taking optical system 1 and its optical target position 5. In the focusing position, LEDs 21 and 26 both go OFF and when the output of a comparator 16 is H level, the LED21 goes ON to display that the focus position should be moved backward. When a comparator 17 is H level, the LED26 goes ON to display that the focus position should be moved forward.
