Abstract: Data processing apparatus for the recognition or analysis of patterns, which may, for example, be character representations requires that the pattern to be processed be divided into elementary areas arranged in a matrix. The matrix of areas is scanned by a corresponding matrix of detecting elements, such as photocells, and the resultant signals are applied as inputs to a plurality of logic units. Each logic unit is, for example, primarily associated with a specific elementary area of the pattern but connections are also provided to the unit from those detecting elements scanning other pattern areas having a particular positional relationship to the primarily associated one. These other pattern areas are typically those immediately surrounding the primarily associated one. A standard timing waveform is applied to the logic units and is modified according to the states of and positional relationships of the pattern areas whose detectors are connected to the logic unit, so that the output of the logic unit has a time relationship to the standard timing waveform which is dependent on these positions and states. For example, the areas with which a logic unit is associated may produce varying delays to the standard waveform and the various waveforms derived in this way may again be recombined. Typically, the states of the areas may produce a half-cycle delay in the waveform and the positional differences of the various areas may produce appropriate phase delays in the waveform. The resultant output waveform may be that made to indicate such features of the pattern as it is desired to recognize, such as, for example, the direction of a line, or the existence of a curve or junction in the line.

Abstract translation: 用于识别或分析图案的数据处理装置，其可以例如是字符表示，需要将要处理的图案划分为以矩阵形式布置的基本区域。 区域矩阵由诸如光电池的检测元件的相应矩阵扫描，并且所得到的信号作为输入施加到多个逻辑单元。 例如，每个逻辑单元主要与图案的特定基本区域相关联，但是也可以从扫描具有与主要相关联的特定位置关系的其它图案区域的那些检测元件向单元提供连接。 这些其他图案区域通常是那些立即围绕主要相关联的图案区域。 将标准定时波形应用于逻辑单元，并根据其检测器连接到逻辑单元的图案区域的状态和位置关系进行修改，使得逻辑单元的输出与标准定时具有时间关系 取决于这些位置和状态的波形。 例如，与逻辑单元相关联的区域可能对标准波形产生变化的延迟，并且以这种方式导出的各种波形可以再次被重新组合。 通常，这些区域的状态可能在波形中产生半周期延迟，并且各个区域的位置差异可能在波形中产生适当的相位延迟。 所得到的输出波形可以是用于指示图案的这种特征，如期望识别的，例如线的方向，或线中的曲线或结的存在。
