Charge coupled device (CCD) image sensors are used as detectors in a low capacity read only memory device. Because of the finite areas of the photodetectors in the CCD device, the output signals from the device can not reproduce exactly the original data. In this paper we discuss a signal processing method for reconstructing the original data from the imperfect CCD signals. Different channel encoding techniques for recording the digital data are also discussed.
