Abstract
In a digital still camera, the amount of blur when a picture is taken is calculated from a first picture captured with a high-speed electronic shutter and a second picture captured with a normal shutter speed (), and the blur in the picture captured with the normal shutter speed, which is degraded by the blur, is corrected through digital signal processing, by applying a picture restoration algorithm (). Blur can be corrected by a simple device, without requiring an angular velocity sensor or a circuit to process its output in order to reduce the effect of camera shake.
