Abstract
A system for capturing sequences of digital images, including a lens, a digital sensor including a plurality of light-sensitive elements, a focusing module suitable for varying the focus of the lens on the sensor, and an electronic processing unit. The electronic processing unit is suitable for determining a variation in magnification between two consecutively captured digital images from a variation in the focus of the lens, and for determining a digital compensation for said variation in magnification. The electronic processing unit is further suitable for digitally processing at least one of the consecutively captured digital images on the basis of said predetermined compensation. The system enables compensation for visual effects resulting from changes in magnification between two consecutively captured images.
