Autofocus camera

摘要

The light having passed through a photographing lens is directed in a form of one pair of optical images to each of one pair of image sensors. The electric charge accumulated in one pair of image sensors is output in the form of the output signal trains. The photographing lens is driven on the basis of an operation result which has been calculated based on the output signal trains and judged to be reliable. The reliability judgment standard for the operation result representing the focus condition is set loose when the electric charge accumulation has been made while the photographing lens is stopped or is set more strictly when the electric charge accumulation has been made while the photographing lens is being driven.
