Abstract: A better compromise between the dynamic range, the spatial resolution, the implementation outlay and the image quality is achieved if different subdivisions of the exposure interval into accumulation intervals are performed for different pixel sensors or pixels. In the event of more than one accumulation interval per exposure interval, the values detected in the accumulation intervals are summed to obtain the respective pixel value. Since the exposure effectively continues to take place for all pixels over the entire exposure interval, no impairment of the image quality arises, or no artifacts arise in image movements. All pixels undergo the same image blur on account of the movement. The additional hardware outlay compared with commercially available pixel sensors is either entirely non-existent or can be kept very small, depending on the implementation. Moreover, a reduction in the spatial resolution is not necessary since the pixels contribute equally to the image capturing.
