Abstract
When an exposure of a film is started, the A/D conversion of angular speed signals output from the X-axis direction and Y-axis direction sensors and the storing of these digitalized angular speed signals to a memory are repeated at predetermined intervals. After the exposure time has elapsed, the A/D conversion and the storing are stopped, and the film is wound by one frame. Angular data are calculated by integrating the digitalized angular speed signals, and a tremble amount is calculated based on the angular data and a focal length of a photographing optical system. The tremble amount is compared with a permissible amount. If the tremble amount exceeds the permissible amount, the exposure is repeated. The photographing is repeated until the tremble amount becomes less than or equal to the permissible amount.
