    • To reproduce colored images, color component signals generated by scanning an original are color corrected and then tone corrected and used to control the exposure of a sensitive surface. ''''Catchlights'''' are reproduced on an extended and nonlinear portion of the tone correction characteristic. To prevent the reproduction on this portion of the characteristic of signals which do not correspond to catchlights but which, through overcorrection in the color correction circuits, have a similar signal level, a catchlight detector circuit is connected in parallel with the color correction circuit so as to receive uncorrected color component signals and to modify the response of the tone correction circuit to a signal from the color correction circuit in the presence of a catchlight signal from the catchlight detector.
    • 为了再现彩色图像,通过对原稿进行扫描生成的颜色分量信号进行颜色校正,然后进行色调校正,并用于控制敏感表面的曝光。 在色调校正特性的扩展和非线性部分上再现“Catchlights”。 为了防止在这一部分对不同于聚光灯的信号的特性进行再现,而通过颜色校正电路中的过度校正具有相似的信号电平,将聚光灯检测器电路与彩色校正电路并联连接,以便 接收未校正的颜色分量信号,并且在存在来自聚光灯检测器的聚光灯信号的情况下,修正色调校正电路对来自颜色校正电路的信号的响应。

    • In image reproduction, joins between different parts of a montage to be reproduced, or other defects in an image, are painted over with fluorescent paint. The image is then scanned with a normal aperture, point by point, to generate densityrepresenting signals and is additionally scanned with a larger aperture to generate further signals. A threshold circuit receiving these further signals is responsive to signals of a level such as to indicate the presence of fluorescent paint within the view of the larger aperture and is operative to substitute for the output of the normal-aperture scanner a signal of predetermined value representing white or a background colour. Thus the defect-representing signals are replaced by the background signals.
    • 在图像再现中,将要再现的蒙太奇的不同部分或图像中的其他缺陷之间的连接用荧光漆涂漆。 然后逐点地以普通孔径扫描图像以产生密度表示信号,并且用更大的光圈附加地扫描以产生更多的信号。 接收这些其他信号的阈值电路响应于诸如在更大光圈的视野内指示荧光漆的存在的电平的信号,并且可操作地代替普通孔径扫描器的输出,表示预定值的信号 白色或背景颜色。 因此,缺陷表示信号被背景信号代替。
