Classification: CPC H  G | IPC G  H

Claim 12:
13. A method for generating a gray-scale image using an imaging system, the imaging system comprising an illumination element configured to emit light and an imaging sensor comprising at least one photo-sensitive element, each photo-sensitive element comprising a first element with a modifiable first charge level and a second element with a modifiable second charge level, the method comprising:
during a first phase, controlling the illumination element to emit light towards a scene and driving the at least one photo-sensitive element such that charge carriers generated in the at least one photo-sensitive element by light received from the scene modify the first charge level;
during a second phase, controlling the illumination element to pause emission of the light and driving the at least one photo-sensitive element such that charge carriers generated in the at least one photo-sensitive element by light received modify the second charge level; and
generating the gray-scale image of the scene based on the first charge level and the second charge level,
wherein the light emitted by the illumination element during the first phase is emitted as a single light pulse,
wherein a time interval between a start of a first light pulse being emitted in the first phase and an end of a last light pulse being emitted during the first phase covers at least 95% of the first phase.
