Abstract

PURPOSE:To make a device small-sized, and also to make a production cost inexpensive, by using a signal for recording, as a signal for detecting a degree of focusing. CONSTITUTION:An output of a solid image pickup element 8 is read out in order in accordance with a command from a controller, is A/D converted by an A/D converter 9, and is stored in an RAMI11 or an RAMII13. Also, video signals of lens positions being mutually adjacent are inputted to the RAMs I, II. Degrees of focusing are calculated by these video signals, the degrees of focusing at the two positions being mutually adjacent are compared by a comparing circuit 16, a memory whose focusing degree is higher, between memories of the RAMI11 and II13 is left, and a memory whose focusing degree is lower is erased. This operation is executed repeatedly extending from the infinite distant position of a lens to the shortest distance position, television of a maximum focusing degree is obtained, and it is stored in a main memory 17.
