摘要： An original to be copied is electrooptically scanned point-by-point. The resulting imaging signals are stored in a first memory and then forwarded to a first image processing unit where the signals are electronically corrected to enhance the image of the original. The corrected signals are loaded into a second memory. A portion of the corrected signals is recalled from the second memory and sent to a third memory. This portion of the corrected signals is then transmitted to a second image processing unit and thereafter converted into a low-resolution video image which can be inspected to determine image quality. If image quality is satisfactory, the contents of the second memory are sent to an exposure unit which prints a high-resolution image of the original on copy material. Imaging signals for a second original are loaded into the first memory as the contents of the second memory are recalled for printing. The second processing unit functions to adjust the video image so that it closely corresponds to the printed image of the original.

摘要： During the ongoing course of the exposure, the aperture area increases linearly to a maximum value and then stays at the maximum value, the instantaneous amount of exposure light therefore changing correspondingly, even if the ambient-light level remains constant during the exposure. A pulse generator includes a photodetector exposed to ambient light and generates a pulse train of light-dependent repetition frequency, the pulses of which are counted by a light-totalizing counter which eventually generates a terminate-exposure signal. Ideally, the repetition frequency should increase steplessly and linearly, for maximum accuracy, or second best increase stepwise in small steps to approximate to a stepless linear increase, but in order to use an extremely low number of stepwise frequency changes, without loss of system accuracy, no attempt is made to per se keep the light-indicating repetition frequency accurate. Instead, the number and amounts of the repetition-frequency changes are so established that, when the repetition frequency is plotted against elapsed exposure time, it is proportional to a piecewise linearization of the time integral curve of the exposure-aperture surface area, the constituent straight-line segments of the linearization being confined within a predetermined error-of-total-exposure tolerance range. In the case of a linear increase of aperture size concluding in maximum size, this corresponding to a quadratic followed by a straight-line rise of the time integral of the exposure-aperture surface area, the requisite time integral curve, despite its complexity, can, for example, be implemented using as few as only three or even as few as two stepwise changes of repetition frequency, without loss of system accuracy.

摘要翻译： 在正在进行的曝光过程中，孔径面积线性增加到最大值，然后保持在最大值，因此即使在曝光期间环境光水平保持恒定，曝光光线的瞬时量也相应地改变。 脉冲发生器包括暴露于环境光的光电检测器，并产生依赖于光的重复频率的脉冲序列，其脉冲由最终产生终止曝光信号的光累计计数器进行计数。 理想情况下，为了最大的精度，重复频率应该无级地和线性地增加，或者以小的步骤逐步增加，以逼近无级线性增加，但是为了使用极低数量的逐步频率变化，而不损失系统精度 没有尝试本身保持指示重复频率的准确性。 相反，重复频率变化的数量和数量是如此确定的，当重复频率相对于经过的曝光时间绘制时，它与曝光孔表面积的时间积分曲线的分段线性化成正比，成分 线性化的直线段被限制在预定的总曝光容差范围内。 在最大尺寸结束的孔径尺寸线性增加的情况下，这对应于二次曲线，随后是曝光孔表面积的时间积分的直线上升，所需的时间积分曲线尽管复杂，但可以 例如，使用只有三个甚至仅次于两次重复频率的逐步改变来实现，而不损失系统精度。

摘要： An analog-to-digital converter is disclosed which utilizes a successive approximation register. The operation of the successive approximation register is so controlled that any analog signal within a dynamic range requiring more bits than the successive approximation register can hold can nonetheless be accurately converted within a predetermined tolerance.
