    摘要: An improved full subtracter is disclosed which receives a minuend signal A having a weight of +1, a subtrahend signal B having a weight of -1 and a borrow input signal Xi having a weight of -1 and provides a difference output: signal D having a weight of +1 and a borrow output signal Xo having a weight of -2. The full subtracter is composed of CMOS transistors such that both the signal D delay time and the signal Xo delay time are decreased by reducing the number of logic gate stages.

    摘要: A foreground live-video image, made up of a "blue back" part, a "hand/arm" part, and a "shadow" part of the "hand/arm" part, is chroma-key composited with a background live-video image. The "blue back" part is displayed to be transparent on the display screen. The "hand/arm" part is displayed to be opaque. The "shadow" part is displayed to be translucent. Whereas a first comparator determines a key color of the "blue back" part, a second comparator determines a key color of the "shadow" part. According to the output code of the first and second comparators, a data selector selects, pixel data of the background live-video image (Va) for the "blue back" part, pixel data of the foreground live-video image (Vb) for the "hand/arm" part, and pixel data found by multiplying each of the pixel data of Va and the pixel data of Vb by a respective weight and summing those products, as respective output pixel data. The "hand/arm" part may be displayed to be translucent by changing the output code relating to the "hand/arm" part by a code converter.

    摘要: A temperature-compensated antilogarithmic converter has a temperature-sensitive signal generator for generating a temperature dependent signal which varies in proportion to absolute temperature; a multiplying means for mixing and converting the temperature dependent signal and an input signal into a product signal; and a non-temperature compensated antilogarithmic amplifier for converting the product signal into a non-temperature compensated antilogarithm of the product signal, wherein by placing the temperature-sensitive element of the temperature-sensitive signal generator and the antilogarithmic element of the antilogarithmic amplifier at the same temperature, the dependance of the antilogarithmic amplifier is temperature compensated by the temperature dependent signal. Thereby, an output converted signal the voltage or current of which is stable with respect to temperature variation can be generated.
