Abstract

PURPOSE:To display an existing state of an objective lens, by A/D-converting an output of an automatic focus detector. CONSTITUTION:This device is equipped with a focus detector S which detects rays passing through an objective lens by a lot of photodetectors and sends out an output of a level corresponding to the position of the objective lens by operating those outputs, an A/D converting circut 6 which compares its detection output with a stair level and generates an output as to an area where it exists, and a display element group 5 corresponding to an area of the circuit 6. And, by display of the element group, stairs in which the objective lens exists are displayed.
