    摘要： A noise reduction method for reducing noise in an input video signal to output an output video signal includes the steps of generating a motion-compensated reference video signal from the output video signal; delaying the output video signal to generate a non-motion-compensated reference video signal; mixing the motion-compensated reference video signal with the non-motion-compensated reference video signal to generate a reference video signal; subtracting the generated reference video signal from the input video signal to generate a differential signal; compensating the differential signal to generate a noise reduction signal; and subtracting the noise reduction signal from the input video signal.

    摘要： In an image encoder, a first quantization section which is selected when normal image quality is required performs quantization by dividing a wavelet transformation coefficient by a quantization step size and by thereafter rounding down a fraction thereof. On the other side, a second quantization section which is selected when high image quality is required performs quantization by dividing a wavelet transformation coefficient by a quantization step size, by adding 0.5 to the addition result, and by thereafter rounding down a fraction thereof. Therefore, the width of a dead zone where coefficients are quantized to a value of 0 is narrower than that in the first quantization section, and higher image quality is obtained accordingly.

    摘要翻译： 在图像编码器中，当需要正常图像质量时选择的第一量化部分通过将小波变换系数除以量化步长进行量化，然后向其舍入其分数。 另一方面，当需要高图像质量时选择的第二量化部分通过将小波变换系数除以量化步长进行量化，通过将0.5加到加法结果上，然后向其舍入其分数。 因此，系数被量化为0的死区的宽度比第一量化部分的宽度窄，从而相应地获得更高的图像质量。

    摘要： An apparatus and a method for compressing a picture by wavelet transform and entropy coding, in which the processing load of arithmetic coding may be relieved and rate control may be carried out effectively, while still maintaining the picture quality. An encoding object prediction unit predicts bitplanes to be encoded and extracts only those bitplanes which are to be encoded. An EBCOT unit generates an encoding pass from one bitplane to be encoded to another to execute arithmetic coding. In controlling the code volume to a target code volume, a rate controller sums the arithmetic codes in a sequence from the arithmetic code with the highest bit position in the totality of the code blocks of an input picture to the arithmetic code of the lowermost bit, from one bitplane to another or from one encoding pass to another, and halts the summation when the predetermined target code volume is exceeded.

The coupling device comprises a female joint and a male joint. The female joint is fitted on a mold and comprises a first valve casing, a first valve body, and a first open/close valve having a first valve seat and a first valve portion. The male joint is fitted on a clamping plate of an injection molding machine and comprises a second valve casing, a second valve body, and a second open/close valve having a second valve seat and a second valve portion. The coupling device further comprises a valve body drive unit. When, in a condition where the front ends of the first and second valve casings and are in contact with each other, the valve body drive unit drives and advances, in the male joint, only the second valve body relative to the second valve casing, the first and second valve bodies and are driven to the valve opening side.
