    • An apparatus for recognizing visual patterns of handprinted characters or the like by means of an optical character reader which reads the patterns by a so-called outermost point method. While tracing the contour of the pattern stored in a two-dimensional memory, the distances from the starting point of the tracing and the integrated values of the coordinates of the points traced on the contour from the starting points are simultaneously obtained successively to extract outermost points for the series of contours. According to this outermost points, the contours are segmented into the convex line segments, concavity line segments and hole segments and the corresponding parameters of features of each segment are detected. Simultaneously, the convex line segment of which is shorter than a predetermined length is rejected and the remaining segments are subjected to matching operation in accordance with preliminarily prepared dictionary, thereby making a decision as to the pattern's identity.
    • 用于通过所谓的最外点法读取图案的光学字符阅读器来识别手印字符等的视觉图案的装置。 在跟踪存储在二维存储器中的图案的轮廓时,连续地同时获得跟踪起始点的距离以及从起点跟踪在轮廓上的点的坐标的积分值,以提取最外点 用于一系列轮廓。 根据该最外点,将轮廓分割为凸线段,凹部线段和孔段,并且检测每个段的特征的对应参数。 同时,其凸线段短于预定长度被拒绝,并且根据预先准备的字典对其余段进行匹配操作,从而对图案的身份做出决定。

    • A program-viewing inhibition device comprises a memory for storing inhibition level data indicative of a predetermined level of unsuitability rating of a broadcasting program, a control section for determining whether or not an input channel received is acceptable by comparing inhibition level data extracted from a broadcast signal of an received input channel with the inhibition level data read out of the memory, and for changing the input channel to another channel when it is judged that the input channel is unacceptable or to be rejected for its viewing. Accordingly, a manual operation to change the input channel to the substitute channel when the input channel is unacceptable for viewing can be eliminated.
    • 节目观看禁止装置包括:存储器,用于存储指示广播节目的不合适等级的预定级别的禁止电平数据;控制部分,用于通过比较从广播中提取的禁止级别数据来确定所接收的输入信道是否可接受 接收到的输入信道的信号,其中从存储器读出的禁止电平数据被读出,并且当判断输入信道是不可接受的或被拒绝用于其观看时,将输入信道改变为另一信道。 因此,可以消除当输入通道不能接受观看时将输入通道改变为替代通道的手动操作。
