Abstract

PURPOSE:To make sure focusing by providing a means which stores the measured results of plural measured points and a means which selects 1st and 2nd lens driving means and operating the 2nd lens driving means based on the stored plural measured results. CONSTITUTION:For instance, when plural objects are photographed, a focus memory mechanism 16 and a shift register 17 are operated. Then, a range finder 3 is operated by means of the final position signal of the mechanism 16 and measured distance information is stored in a storage circuit 19. Secondly, the range finder 3 is operated by means of the signal of a release mechanism 1 and the measured distance information is stored in a storage circuit 5. Moreover, when the mechanism 1 is operated, an arithmetic starting signal (c) is outputted to an arithmetic circuit 7 and a median is calculated. After the median is inputted into a comparison warning arithmetic circuit 11 and each stored information is compared whether it is in the depth of field or not, the information is inputted into a lens driving control circuit 13. Then, a photographing lens is operated and stopped in a focusing position. Therefore, the lens is focused on and adjusted to the median of the depth at the plural measured points and can focus on each object.
