Abstract
A camera that is equipped with a function of preventing a blurring of a picture caused by a hand movement of the camera operator. The camera comprises a first detector which detects a moving speed of the camera caused by a hand movement of the camera operator. An image moving speed on a film surface is then calculated on the basis of the moving speed detected by the first detector. A second detector detects a peak speed of the calculated image moving speed and a time of the peak speed. A presumptive image moving speed and a presumptive image moving quantity after the time of detecting the peak speed are then calculated on the basis of the peak speed and the time of the speak speed. In this way, the camera can function to control an exposure time and prevent a picture from blurring due to a hand movement by the camera operator, while still providing a camera which is small in size and simple in construction.
