Abstract
A method, apparatus and image capture device for limiting motion blur during capture of an image predetermines a relationship between movement of the image capture device, time and blur extent. A rate of movement of the image capture device is obtained and used in conjunction with the determined relationship and a blur extent limit as a basis for obtaining a maximum exposure time for the image capture device in order to limit blur extent. On the basis of the maximum exposure time obtained and a required image brightness, the image capture device is configured, and then an image is captured by the image capture device. Once the image has been captured, due to the possibility of under-exposure from having limited the exposure time, the image is processed as required to increase its intensity.
