Title: Method and device for compressing image and software storage medium
Inventor: UNO MASAHIRO
IPC: H04N19/60
Filed: 2000-04-17
Abstract: PROBLEM TO BE SOLVED: To effectively encode and compress an all celestial sphere type photographed image. SOLUTION: An all celestial sphere image is divided into pole parts and other parts and then segmented. Each pole part is approximately circular and projected on a plane circle to undergo a compression process. In this compression process, the polar coordinates defining the center of circle as its origin can be expressed. Meanwhile, the parts other than periphery of poles are divided into almost trapezoidal areas surrounded by latitudinal and longitudinal lines respectively with prescribed spaces secured among them. Then a trapezoid is interpolated into a rectangle so that an encoding compression process based on the conventional orthogonal coordinate system can be applied. It is expected that the compression effect is improved when an even pattern such as the sky or ground is used at the upper and lower pole parts.

Title: Digital radio equipment
Inventor: IWAKI YOSHIYUKI
IPC: H04B1/3822
Filed: 2000-05-15
Abstract: PROBLEM TO BE SOLVED: To solve problems of conventional digital radio equipment that has had extraordinary difficulty of matching its transmission output with a proper level because it is required to reduce the transmission time, in the case of burst transmission where transmission and transmission stop are repeated in a short time in the TDMA system or the like although the transmission characteristic requires control at a large time constant for gradual matching with a proper power level with respect to frequent fluctuations in the output level of a power amplifier due to its secular change and its temperature change to keep the stability of the transmission characteristic by means of maintaining the output level to be a specified value and that has caused a transmission output level in excess of a prescribed range until a peak level is averaged,  to match the power level with the proper power level when a peak factor is high. SOLUTION: Feedback signal data whose level is detected are captured only during transmission to obtain an average value and a level of the feedback side is changed to bring the average value to a specified value. Furthermore, when a base band signal output level continues its maximum state, the level of the feedback side is changed by a fixed value obtained in advance to keep the output level at the specified value independently of the communication system and the modulation system, thereby preventing the transmission characteristics from being deteriorated.
