A method for producing a time sequence of images of motor vehicle surroundings from a virtual elevated central perspective on a display wherein several cameras are used to record time sequences of subimage data records from a plurality of real perspectives differently offset and tilted with respect to the virtual perspective. Then, parameterized transformations are applied for obtaining sequences of transformed subimage data records and overall image data for an overall image from the virtual perspective is assembled. Finally, the sequence of the overall image data is displayed as an overall image. To compensate for positional and/or orientation deviations in the recording cameras a selection unit is proposed to recurrently apply a selection criterion for selecting a subimage data record from the sequence and to take this as a basis for redetermining the parameters of the transformations by an optimization method under a quality criterion for the overall image.
