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: Apparatus for processing information signals in a plurality of information channels comprises a comparator (634-648) for comparing samples of a first information signal in a first channel (Y) with a plurality of selected combinations of the samples of the first signal (Y). A selecting means (650) selects from among the plurality of selected combinations that combination which is the best match with the samples being compared. A generating means (706- 772) generates new samples within at least a second of the plurality of information channels (I) by use of the signal (I) in the second channel and the best match combination.

Abstract: Systeme de reglage automatique pour une camera de television couleur (14) pour corriger les erreurs geometriques dans le canevas et les erreurs d'amplitude du video. Le systeme comprend des moyens (13, 27) de mesure des erreurs, positions ou amplitudes des signaux de sortie de la camera a differents emplacements des lignes rouges, vertes et bleues du canevas pour transmettre simultanement des signaux detectes correspondant aux erreurs de positions ou d'amplitudes de ces regions a des moyens de traitement des signaux (24). Les moyens de traitement (24) selectionnent et separent lesdits signaux detectes en fonction d'une pluralite d'algorithmes pour produire une pluralite de signaux de correction. Les signaux de correction sont appliques (28) a la camera (14) pour regler la camera en fonction de tous les signaux de correction avant de remesurer les lignes de canevas.

Abstract: Apparatus for a television camera is described wherein the highest peak intensity of one of the primary colors is processed to form a multiplying control signal. The control signal is used to compensate a video signal in order to obtain a reduced range of contrast values capable of being adequately displayed by the system.
Abstract translation: 描述了用于电视摄像机的装置，其中处理一种原色的最高峰值强度以形成乘法控制信号。 控制信号用于补偿视频信号，以获得能够被系统充分显示的对比度值的减小的范围。

Abstract: A parallel-striped color encoding filter balanced for white light is placed in front of a television camera pickup tube to encode scene light. The signal obtained from the pickup tube is decoded electrically to yield two color difference signals which may be matrixed to produce signals representative of the red, green and blue light from the scene. The average transmission of the encoding filter produces low frequency components which are representative of the brightness of the scene.
Abstract translation: 将平行条纹的彩色编码滤光器平衡白光放在电视摄像头拾取管的前面，对场景光进行编码。 从拾取管获得的信号被电解解以产生两个色差信号，其可以被矩阵化以产生表示来自场景的红，绿和蓝光的信号。 编码滤波器的平均传输产生代表场景亮度的低频分量。
