Abstract
There is provided a method, system, and non-transitory computer-readable storage medium for controlling the exposure settings of an rolling shutter image sensor device with global reset. This is achieved by obtaining a first image captured by the image sensor device at a current exposure setting that comprises a partial readout parameter representing a number image parts for partial readout by the image sensor device; determining an intensity value of the first image, comparing the intensity value of the first image to a desired intensity value. If the intensity values differ more than an allowed deviation, an updated number of image parts for partial readout is determined based on the current number of image parts and the intensity value of the first image. Thereafter, the current exposure setting is updated by setting the value of the partial readout parameter to the updated number of image parts.
