addition to rendering high-contrast or false-color images, the CCD and
computer together can detect and resolve images much fainter than is
possible with conventional camera film or more primitive types of video
cameras. This makes the CCD useful in robots that must employ night
vision. Compare IMAGE ORTHICON and VIDICON.
