    Abstract: Two or more CCD imagers (12, 14), which have random defects are optically coupled to form a single image. The CCD's are in registry. Because of the random nature of the location of the defects, the defective photosensors of one imager (12) are aligned with good photosensors of another (14). Memories (34, 36) keep track of which locations of which CCD are defective. The imagers (12, 14) are operated synchronously and the signals from good photosensor locations are summed for improved signal-to-noise ratio. When a location is addressed at which one imager (12) has a defective photosensor, the respective memory (34) decouples it from the good photosensor of the other imager (14). The signal level is restored for that location by increasing the gain of a preamp (46) by the correct amount. If the imagers (12, 14) are made from the same mask, they may have almost identically corresponding defective photosensors. Then one imager (12) is mounted upside-down relative to the other (14) and scanned backwards so the defects do not coincide.

    Abstract: A wide-angle television system, such as one having 2:1 or 5:3 aspect ratios, transmits end portions that exceed the limits of a conventional 4:3 aspect ratio picture in regions that are normally hidden from view in a conventional receiver. Thus the system is compatible with such a receiver. These regions can comprise the overscan region, blanking intervals, high frequency portions of a chroma signal, etc. Time compression of the end portions can also be used. At a wide-angle receiver, inverse processing is used to reassemble a wide-angle picture.

    Abstract: A digital signal coring circuit removes from a stream of incoming digital data words low-valued variations lying between upper and lower threshold reference values. Upper and lower threshold values are adjusted in response to the value of the outgoing cored digital data words so that such low-valued variations are removed over the entire range of values of the digital data words, and not merely around a baseline value.

    Abstract: A signal integrating capacitor receives signal current for an integration circuit. A current shunt is coupled to the capacitor. The integrated output is differentiated and degeneratively fed back to the shunting circuit to control the amount of signal current bypassed from the capacitor, thereby increasing the effective time constant associated with the capacitor.
