Abstract: A method for reading a demodulation pixel of a distance sensor for determining a distance, in particular for determining the difference between two charge quantities independently of the total magnitude of the charge quantities, and also a distance sensor are proposed. For faster signal processing, provision is made for applying a variable control voltage to the transfer gates for influencing the potential wall, and lowering the respective potential walls of the corresponding transfer gates, before and/or until from the storage gates in each case charge carriers can surmount the respective potential wall of the corresponding transfer gate and pass to the assigned floating diffusion.

Abstract: The image sensor according to the invention is an image sensor with a matrix of pixels for generating a resulting image with a higher dynamic range from the acquisition of two original images, wherein the pixels of the image sensor are designed as demodulation pixels, wherein each comprises a conversion region for generating charge carriers from the received radiation, a separation device for temporally separating the generated charge carriers into two charge carrier streams, a memory device with two memories for separately storing the charge carriers of the two charge carrier streams, and a read-out device for converting the stored charge carriers into electrical signals, wherein the separation device is designed to carry out the separation of the charge carriers generated in one period into two different time periods.
