Abstract
The quality of recorded images with for example a high speed camera can be detonated by light modulation which is a consequence of for example gas-discharge lamps running at a lower frequency with respect to the camera. A camera according to the invention provides light modulation removal means which tackle this problem by handling fields of the image different depending on the light modulation.
Claims11
Camera for recording pictures comprising an image sensor for receiving a picture, a processing unit for processing the picture and an end processing unit, characterized in that the camera comprises a light modulation removal means between the processing unit and the end processing unit for removing light modulation between different fields of the picture.
Method of removing light modulation during recording pictures with an image sensor having the step of receiving the picture, processing the picture, removing the light modulation by storing different field of the picture and averaging the different fields in dependence of motion, and/or locations with low respectively high luminance locations.
