    • A galvanometric tilting-mirror scanning system shifts an image of an original projected onto a photodiode row in a direction transverse to such row. The tilting-mirror mechanism is provided with an oil-filled damping chamber, heated and maintained at stabilized temperature. The control voltage driving the tilting-mirror system includes a sawtooth component whose lower-slope flanks determine the mirror's scanning sweep; a negative pulse which effects mirror tiltback or flyback; a positive pulse which brakes the tiltback and accelerates the mirror back up to its forwards-direction scanning-sweep speed; and finally a corrective component. The corrective component has the form of a pulse which increases the slope of the sawtooth component's lower-slope flanks during a time interval extending beyond the system's vertical blanking allotment, to compensate the non-linearity in the motion of the mirror which would exist during its forwards-direction scanning-sweep interval in the absence of the corrective component.

    • A projection and scanning system for synchronization of photographic film projection with vertical sync pulses is taught. In this system, developed photographic film is advanced into a projection gate which is larger than the vertical height of an individual photographic frame. As a given film frame passes through the projection gate, it is repeatedly scanned by a mirror and the projected image reflected onto a charge-coupled image sensor which can be used to provide information for a video signal. Perforations on the film enable pulses to be developed at a photocell which are a function of film speed. By processing these pulses, along with vertical sync pulses and appropriate control waveforms, accurate scanning of the film can be achieved, enabling video signals resulting in flickerless television transmissions to be generated.
    • 教导了用于摄影胶片投影与垂直同步脉冲同步的投影和扫描系统。 在该系统中,显影的照相胶片被推进到比单独的照相框的垂直高度大的投影门。 当给定的胶片框架通过投影门时,它被反射镜重复扫描,反射到电荷耦合图像传感器上的投影图像可以用于提供视频信号的信息。 胶片上的穿孔使得能够在光电池上产生脉冲,这是膜速度的函数。 通过处理这些脉冲以及垂直同步脉冲和适当的控制波形,可以实现胶片的精确扫描,使视频信号产生无闪烁的电视传输。

    • Super-8 motion-picture film is transported non-intermittently at constant speed, and its image is projected into an image plane in which is located a single row of photodiodes which extends transverse to the film transport direction. The photodiodes of the single photodiode-row are successively responsive to red, blue and green wavelengths. A bucket-brigade circuit or CCD including the photodiode-row furthermore includes a shift register which receives the photodiode signals in parallel, is then read out serially, with its output signal then time-division demultiplexed to obtain separate red, blue and green signals; or else three shift registers are used, each receiving signals only from those photodiodes responsive to a respective one of the three component colors. Whereas the photodiode-row is responsible for horizontal scanning, vertical scanning is achieved in part due to film transport per se and in part due to a tilting-mirror deflector which deflects the image projected onto the photodiode-row. The tilting-mirror deflector is a galvanometric moving-coil mechanism, and is energized by a sawtooth waveform to effect forwards scanning and abrupt vertical-direction flyback or tiltback, and is provided with special brief pulses for effecting abrupt direction reversals of the tilting mirror.
    • Super-8电影胶片以恒定的速度非间歇地传送,并且其图像被投影到图像平面中,其中位于横向于胶片传送方向延伸的单行光电二极管。 单个光电二极管行的光电二极管依次响应红色,蓝色和绿色波长。 包括光电二极管行的斗式电路或CCD还包括并行接收光电二极管信号的移位寄存器,然后其输出信号被顺序解复用以获得单独的红色,蓝色和绿色信号; 或者使用三个移位寄存器,每个移位寄存器仅接收来自响应于三个分量颜色中的相应一个的那些光电二极管的信号。 尽管光电二极管行负责水平扫描,但是部分由于胶片输送本身而部分地实现了垂直扫描,部分是由于倾斜镜偏转器使投影到光电二极管行上的图像偏转。 倾斜镜偏转器是电流计动力线圈机构,并且由锯齿波形激励以实现向前扫描和突然的垂直方向回扫或倾斜,并且具有用于实现倾斜镜的突然方向反转的特殊短暂脉冲。

    • A colored original to be reproduced is scanned point-by-point in each of the three primary colors. The resulting imaging signals are processed to generate a luminance signal and a pair of chrominance signals. The luminance signal is branched into a high-pass filter channel and a low-pass filter channel. The high-pass portion of the luminance signal is amplified in accordance with a sublinear characteristic function which causes signals of small amplitude to be amplified to a greater degree than signals of large amplitude. The low-pass portion of the luminance signal is modified per a non-linear characteristic gradation function. The thus-modified high-pass and low-pass portions of the luminance signal are added to yield an enhanced luminance signal. The enhanced luminance signal is divided by the original luminance signal and each of the chrominance signals is multiplied by the resulting quotient. This automatially compensates for the changes in color saturation which accompany changes in brightness. After the multiplication, the chrominance signals are amplified in accordance with a sublinear characteristic function which causes signals of small amplitude to be amplified to a greater degree than signals of large amplitude. This characteristic function further has a form such that no additional ampification takes place beyond a predetermined threshold limit.

    • The dynamic random access memory for use in a video circuit scanning video images according to the interlaced scanning method and reproducing the images on monitors of different resolutions is described. The RAM memory is composed of as many RAM segments as there are graduations of picture elements available, each segment including a plurality of RAM chips determined by the minimum read/write cycle time and by the scanning cycle time. To speed up the addressing during the switchover from the low-resolution to a high-resolution reception, the memory is organized into two halves, for storing respectively signals pertaining to odd-numbered and even-numbered picture lines. In each half, the vertical columns are subdivided into groups of lines pertaining to a single video data word. The adjoining pairs of columns store the signals pertaining to corresponding pairs of consecutive video lines which, in each pair, are arranged one below the other. In this manner the access time in the memory during the low-resolution is made faster.
    • 描述了用于视频电路中的动态随机存取存储器,其根据隔行扫描方法扫描视频图像并再现不同分辨率的监视器上的图像。 RAM存储器由可用的像素刻度的RAM段组成,每个段包括由最小读/写周期时间和扫描周期时间确定的多个RAM芯片。 为了加快在从低分辨率切换到高分辨率接收的切换期间的寻址,存储器被分成两半,用于分别存储与奇数和偶数图像行有关的信号。 在每一半中,垂直列被细分为与单个视频数据字有关的一组行。 相邻的列对存储与相应的连续视频对对相关的信号,每对连续的视频行在每一对中彼此排列。 以这种方式,在低分辨率期间存储器中的访问时间变得更快。
