Abstract
A color television camera has a semiconductor image sensor composed of sensor elements of the CCD type arranged in a raster. The charges produced in the sensor elements within an integration interval are read out as video signals. The image on the semiconductor image sensor is shifted in the horizontal direction by a fraction of a raster unit of measurement from one integration interval to the next integration interval in a cyclical fashion. An increase of the resolution in the vertical direction will then result by reading out the video signals from the semiconductor image sensor. The horizontal image shift is produced in the optical path between the objective lens of the image sensor by means of filter disk mounted so as to be bistable. The filter disk can thereby be flipped through a predetermined angle and back between integration intervals of the image sensor.
