Abstract

PROBLEM TO BE SOLVED: To improve the operability of a photographing device that photographs an object by using a display section that can be turned without providing an operation key of the same function to each position offering each of operation in each photographing state. SOLUTION: When an electronic view finder(EVF) 19 is turned and reaches a low angle state, a microcomputer (turning detection means, revision means) 8 revises an operation key SW1 as an AF(automatic focus) ON/OFF key in a conventional photographing state into an ON/OFF key for recording and recording temporary stop operation. In this case, a key function display LED 15 is lighted to inform an operator about the change in the operation function.
