摘要： The invention provides a color corrector which carries out color correction by comparing a test chart signal generated by a test chart signal generating circuit provided in a color TV camera or externally with an image signal from a camera of the test chart. To do automatic color correction on the basis of various data by the use of circuits for automatizing these functions, and to produce a special effect by carrying out color corrections for TV cameras based on color correction data produced from the image signal of one TV camera, the same color correction for TV cameras can be simultaneously performed on the basis of color correction data of one camera.

摘要： A device for forming brightness signals in a color TV camera in which a plurality of solid imaging elements are so arranged that the pixels are spatially deviated. In the bands other than a predetermined video band where primary color signals are added up at a three primary color ratio corresponding to the reproduction of a standard white color to form brightness signals, the primary color signals are added up at a ratio of time relations corresponding to the deviated amount of pixels to form brightness signals in order to obtain a high resolution that could not be obtained with a three primary color ratio corresponding to the reproduction of the standard white color in the bands other than the above video band thereby to improve the resolution in a high-frequency band before the signals are transmitted as TV signals.
摘要翻译：一种用于在彩色电视摄像机中形成亮度信号的装置，其中多个固体成像元件被布置成使得像素在空间上偏离。在除了预定的视频频带之外的频带中，其中原色信号以对应于标准白色的再现的三原色相加相加以形成亮度信号，原色信号以对应的时间关系的比率相加对于偏移量的像素以形成亮度信号，以便获得与除了上述视频带之外的频带中的标准白色的再现相对应的三原色比率不能获得的高分辨率，从而改善信号作为电视信号发送之前在高频带中的分辨率。

摘要： A contour emphasizing device for TV cameras wherein a level correction circuit is interposed to non-linearly process the video signals from a TV camera to send them to a contour emphasizing circuit. In a region of dark image, the contour is emphasized by the level-enhanced signals, while in a bright region the contour emphasis is properly suppressed to obtain natural image.
摘要翻译：一种用于TV摄像机的轮廓强调装置，其中插入一个电平校正电路以非线性地处理来自TV摄像机的视频信号，以将它们发送到轮廓强调电路。在黑暗图像的区域中，轮廓被水平增强信号强调，而在明亮区域中，轮廓强调被适当地抑制以获得自然图像。
