Claim Text:
1. A method of using an image sensor for recording frames in fast succession, the image sensor comprising at least one row of light sensors registering incident light as electric signals and at least one shift register including a first and a second register place per each light sensor of the at least one row of light sensors, and configured to transfer the electric signals from the light sensors to the respective first register places and to shift the electric signals on selected ones of the first and second register places forward register place by register place in the shift register, the method comprising: after a first exposure time of the plurality of exposure times, adding the electric signals from each of a plurality of groups of at least two light sensors neighboring in the row of light sensors on one of the first and second register places, and after a second exposure time of the plurality of exposure times, adding the electric signals from each of the same groups of at least two light sensors neighboring in the row of light sensors on one of the first and second register places located between two of the first and second register places on which added electric signals from the first exposure time are present, wherein, after the first exposure time, the electric signals from all light sensors are simultaneously transferred to the respective first register places, and wherein, afterwards, the electric signals from each of the groups of light sensors are added on the foremost first register place belonging to the respective group of light sensors by primarily shifting forward those electric signals which have been transferred to further backward first register places in the shift register.
