摘要： An image compressing apparatus employs a mean-separated normalized vector quantization method according to which, with respect to vector components corresponding to input images inputted from image sensors via a plurality of lines, encodes and outputs a scalar-quantized code of a mean value, a scalar-quantized code of a maximum scalar product value with each code word in a code book, and an index of one of the code words which yields a maximum scalar product value. In this image compressing apparatus, when the maximum scalar product value is less than a predetermined threshold value, in accordance with judgement by a comparator circuit, an output selecting circuit stops outputting the codes of the maximum scalar product value and of the index, and outputs only the code of the mean value. Therefore, when the image is uniform with pixels varying little in their luminance levels in compression processing unit blocks, code data to be outputted are restricted so that only data of the mean value are outputted. Consequently, it is possible to restrain degradation of the image and to considerably reduce data amount.
摘要翻译：图像压缩装置采用平均分离的归一化矢量量化方法，根据该量化方法，对于与通过多行从图像传感器输入的输入图像相对应的矢量分量，编码并输出平均值的标量化码，具有代码本中的每个代码字的最大标量积值的标量化代码，以及产生最大标量乘积值的代码字之一的索引。在该图像压缩装置中，当最大标量乘积值小于预定阈值时，根据比较器电路的判断，输出选择电路停止输出最大标量乘积值和索引的代码，并输出只有代码的平均值。因此，当在压缩处理单元块中图像的亮度级别变化很小的图像均匀时，要输出的代码数据被限制，从而仅输出平均值的数据。因此，可以抑制图像的劣化并且显着地减少数据量。

摘要： In respective comparators, a plurality of input voltages are compared with a comparison voltage that has been swept, and only the binary output of a D flipflop corresponding to the comparator that has exceeded the comparison voltage earliest is allowed to have "1", while the outputs corresponding to the rest of the comparators have "0". Therefore, it is possible to detect a maximum output by using the comparators of a normal CMOS construction and a binary-change detection means circuit constituted by logical circuits. Compared with the application of floating-gate MOS, this arrangement makes it possible to reduce costs, and also to easily carry out offset-voltage compensation for each comparator by using switched capacitors. As a result, in a maximum input detector which detects a maximum input from analog inputs through multiple channels by carrying out analog operations, it is possible to reduce costs, and also to improve detection precision.

摘要： An encoding apparatus uses a vector quantization encoding method for encoding indexes of codewords, which supply a scalar quantized code of a maximum scalar product value of each code word in a code book, and its maximum scalar product value to a vector component of an input image inputted from an image sensor, so as to output the encoded indexes. A scalar product value calculating circuit in the encoding apparatus has scalar product value calculating sections, which are composed of an analog circuit having a code component capacitor corresponding to each code component, a differential amplifier and a feedback capacitor, corresponding to each codeword, and the scalar product values of the input vectors are calculated in parallel by the scalar product value calculating sections. In such a manner, when the analog calculation is made, the scale of the circuit can be decreased and the power consumption can be lowered. Therefore, unlike the case where the calculation is made after A/D conversion, it is possible to avoid a problem that the number of times of calculations and the power consumption are remarkably increased due to increases in the number of dimensions of the input vector and the number of gradations.

摘要： A winner-take-all circuit for judging a channel receiving an analog signal having the largest or smallest value among multiple channels upon input of analog signals. Each basic circuit includes a detecting unit for comparing an input voltage with a reference voltage, and a feedback current generating unit for outputting a feedback current that determines a judging range in response to an output voltage from the detecting unit. The winner-take-all circuit also includes a tenth transistor serving as a common transistor to all the basic circuits. The tenth transistor secures, even when an input voltage is small, a current that should flow through a sixth transistor serially connected to the seventh transistor that determines an amount of a feedback current from the feedback current generating circuit. As a result, even when there are fewer k channels receiving input voltages having the highest level and slightly lower ones compared with all the n channels, a feedback current is secured in a sufficient amount to vary the reference voltage. In addition, the winner-take-all circuit of the present invention comprises analog circuits, thereby making the structure simpler compared with a counterpart that processes digital signals.

摘要： Properties of a green sand for casting composed of siliceous sand, a combination of Na-type and Ca-type bentonite and water can be improved by utilizing surface activating characteristics of a waste liquor from the pulp manufacturing process. When a pulp cooking waste liquor having a pH of 9 to 13 or a concentrate or powder thereof is incorporated into this green sand, the green strength, the flowability and the packing property are remarkably improved. The used green sand mold has a good disintegrating property and the handling of the return sand is performed very easily, and the temperature control of the return sand can be remarkably facilitated. Further, when this green sand composition is used, occurrence of such defects as buckles, scabs, sand marks and cuts is effectively prevented. When an aluminum ion or transition metal ion is incorporated together with the pulp cooking waste liquor, the foregoing effects are further enhanced.
