    • An image readout device is constructed to read out a partial image from a total image stored in photo detectors arranged in at least one row or two-dimensionally in rows and columns. The partial image may be of interest for a particular purpose, for example for the identification of a target, which does not require the processing of all the data representing the total image. The readout is accomplished by a series of switches arranged in a row and controlled by two shift registers in response to shift clock pulses. A logical "high (1)" state is loaded into a first shift register position (A) corresponding to the first detector position to be read out. All other shift register positions are loaded with the logical "low (0)" state. These logical states are then shifted in parallel into another second shift register which addresses the row of switches in a serial manner. A predetermined number of shift clock pulses determines the shift of the logical "high (1)" state from the first position (A) to a second position (B). These positions (A, B) determine the beginning and the end of the partial image readout of a row of photocells for example. The output signal at the output of the row of switches is provided only for those positions or locations which are determined by the shifting logical "high (1) " state. No output signal is provided for positions in the logical "low (0)" state. Thus the data flow and correspondingly the software and hardware have been substantially reduced.
    • 图像读出装置被构造成从存储在以行和列排列成至少一行或二维的行和列中的光检测器中的总图像中读出部分图像。 对于特定目的,部分图像可能是感兴趣的,例如用于识别目标,其不需要处理表示总图像的所有数据。 通过响应于移位时钟脉冲由一系列开关排列并由两个移位寄存器控制读出。 逻辑“高(1)”状态被加载到与要读出的第一检测器位置对应的第一移位寄存器位置(A)中。 所有其他移位寄存器位置都加载逻辑“低(0)”状态。 然后将这些逻辑状态并行地移位到另一个第二移位寄存器中,该第二移位寄存器以串行方式寻址该行的开关。 预定数量的移位时钟脉冲确定逻辑“高(1)”状态从第一位置(A)到第二位置(B)的移位。 这些位置(A,B)确定例如一行光电管的部分图像读出的开始和结束。 开关行的输出处的输出信号仅为由移位逻辑“高(1)”状态确定的那些位置或位置提供。 没有为逻辑“低(0)”状态的位置提供输出信号。 因此,数据流和相应的软件和硬件已经大大减少。
