Claim 0:
1. 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;
generating the gray-scale image of the scene based on the first charge level and the second charge level; and
controlling the illumination element to further pause the emission of light at the beginning and/or at the end of the first phase,
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 most 90% of the first phase.
