摘要： A picture encoding system which performs a prediction of picture element values within a block having a plurality of picture elements into which an original picture is divided, a discrete sine transform with respect to prediction error signals for obtaining a transform coefficient, a quantization of the transform coefficient for encoding quantized indexes, an inverse quantization of the quantized indexes for reproduction of the transform coefficient, an inverse discrete sine transform of the reproduced coefficient to reproduce the prediction error signal, and an addition thereto of the predicted picture element value for reproducing the picture element values within the block to employ them in predicting a next stage block to be encoded, whereby the block can be minimized in size while simplifying required transform operation.

摘要： A visual image sensor system for detecting an abnormal change in a monitored scene is disclosed, wherein normal changes which may occur in the monitored scene are previously memorized to be selectively compared with changes in the monitored scene, whereby the normal changes are discriminated from the actual abnormal change to be detected. An alarm is issued when the monitored scene includes a change different from any of the memorized normal changes selected according to one or more rational selection standards, whereby false or redundant alarms due to the normal changes are prevented. For further precise detection, abnormal changes which may occur in the monitored scene are also previously memorized to be compared with the changes in the monitored scene.
摘要翻译：公开了一种用于检测被监视场景中的异常变化的视觉图像传感器系统，其中可以在监视场景中发生的正常变化被预先存储以选择性地与监视场景中的变化进行比较，从而将正常变化与实际异常变化被检测。当监视场景包括与根据一个或多个合理选择标准选择的任何存储的正常变化不同的改变时，发出报警，从而防止由于正常变化引起的假或冗余报警。为了进一步精确地检测，监视场景中可能发生的异常变化也被预先存储以与被监视场景的变化进行比较。

摘要： An individuality discriminating system wherein analog signals of a human individual picture are converted to digital signals according to brightness of the picture, and such digital signals are stored as individual picture data in an integrated-circuit (IC) card as compressed, with picture elements other than changed ones in the picture treated as zero picture elements, while in using the IC card by its bearer the thus stored data are read out of the card as expanded and analog-converted for display on a monitor. Since the picture data are compressed to remarkably reduce code volume upon the storing in the card, the individuality discrimination can be realized practically precisely and effectively reliably through an investigators's comparison with eyes of the thus displayed picture with a directly viewed or monitored picture of the bearer.
摘要翻译：一种个性鉴别系统，其中个人图像的模拟信号根据图像的亮度被转换为数字信号，并且这些数字信号作为压缩的单个图像数据被存储在集成电路（IC）卡中，其中图像元素等比较在图像中被处理为零图像元素的变化的图像，而在通过其承载使用IC卡时，将这样存储的数据从扩展和模拟转换中读出，并显示在监视器上。由于图像数据被压缩以显着地减少存储在卡中的代码量，所以可以通过调查者与所显示的图像的眼睛的比较直接观察或监视承载图像，可以实际上精确有效地可靠地实现个性辨别。

摘要： A picture transmission system of the present invention is adapted to code picture data by a variable sampling rate coding system to transmit the same. Picture data are stored in a frame memory (16) of a transmission area so that differential values between the same and predictors from a predictive circuit (43) are obtained by a subtracter (41) and compression-coded by a variable sampling rate compression circuit (42) to be transmitted. The compression-coded differential values are expansion-decoded by a variable sampling rate expansion circuit (40) so that original differential values are supplied to an adder (45). The adder (45) adds up the differential values with predictors, to produce predictors for subsequent sampling points. In a receiving area, transmitted codes are expansion-decoded by a variable sampling rate expansion circuit (51), so that the decoded values are added up with predictors from a predictive circuit (53) by an adder (52) to output the original picture data. Preposition prediction and variable sampling rate decoding are thus combined to enable, in the receiving area, automatic correction of compression/expansion errors caused in the transmission area.
