Abstract
Devices, systems, and methods for controlling a shutter of a still or video camera or cellular telephone, to reduce blurring due to motion of vibrations are disclosed. The control device includes an inertial sensor for measuring acceleration, velocity and/or angular rotation and for providing data therefrom and a controller for calculating an acceleration amplitude and frequency for predicting the time between acceleration maximums. The controller opens and closes the camera shutter at a time corresponding to the predicted time between maximum accelerations as measured from a real-time acceleration maximum, negating the need for post-imaging correction.
