METHOD AND SYSTEM FOR CAPTURING SEQUENCES OF IMAGES WITH COMPENSATION FOR VARIATIONS IN MAGNIFICATION

摘要

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.

1. A method of capturing a sequence of digital images, the method comprising:
imaging a scene on a digital sensor, through a lens unit, with at least one first magnification value and at least one second magnification value, the second magnification value being different from the first magnification value and a variation between said magnification values arising from a variation in focus of the lens unit; capturing a first digital image with the first magnification value; capturing a second digital image with the second magnification value; determining a digital compensation for the variation between said magnification values; applying digital processing to the first digital image and/or to the second digital image, based on said determined digital compensation.
