    • A picture processing apparatus for picture-in-picture applications where the number of pixels n in the horizontal direction of an original picture, the number of pixels m in the vertical direction thereof, the number of pixels N in the horizontal direction of the converted picture, and the number of pixels M in the vertical direction thereof are supplied to a dividing device. Thus, ratios A=N/n and B=M/m are obtained. The inverse number 1/A of the value A is cumulated by circuits. An address generating circuit generates addresses at four points for calculating a density value a of a converted pixel corresponding to the integer part of a cumulated value &Sgr;(1/A). These addresses are supplied to memories. The pixel data at the four points that are read from the memories are supplied to respective multiplying devices. The decimal part of the value &Sgr;(1/A) is supplied as an interpolating coefficient p to a multiplying device. A coefficient (1−q) is supplied to a multiplying device. Likewise, in the vertical direction, coefficients q and (1−q) are supplied to respective multiplying devices. These multiplying devices and adding devices perform operations. Thus, the density value a of the converted pixel is obtained and supplied from a terminal.

    • A phase control apparatus which enables efficient execution of phase adjustment operations for two transmission signals so that a non-interruptive switchover function will work effectively. The proposed apparatus performs phase control to eliminate a phase difference between two reception signals which originate from a single source, but have been carried over two separate transmission lines. A delay memory unit, placed on each transmission line, delays each reception signal in accordance with a given delay time parameter. A comparison range setting unit defines a time range for phase comparison. Within the defined time range, a phase comparator compares the phases of two reception signals delayed by the delay memory units. If the phase comparison has resulted in an out-of-phase condition, a phase controller repetitively varies the delay time parameter being set in one of the delay memory units until an in-phase condition is reached.
    • 一种相位控制装置,其能够有效地执行两个发送信号的相位调整操作,使得非中断切换功能将有效地工作。 所提出的装置执行相位控制以消除源自单个源但已经在两条分离的传输线上传送的两个接收信号之间的相位差。 放置在每个传输线上的延迟存储器单元根据给定的延迟时间参数延迟每个接收信号。 比较范围设定单元定义相位比较的时间范围。 在规定的时间范围内,相位比较器比较由延迟存储单元延迟的两个接收信号的相位。 如果相位比较导致异相状态,则相位控制器重复地改变在一个延迟存储器单元中设置的延迟时间参数,直到达到同相状态。

    • To achieve a pulse wave measuring apparatus whereby the sensor unit can be easily and consistently worn against the skin surface, a wristwatch type pulse wave measuring apparatus is comprised as follows. Specifically, light transmittance plate 34 is disposed on the outside surface side of LED 31 and phototransistor 32 in sensor unit 30. Outside surface 341 of light transmittance plate 34, which is pressed against the finger, projects above the reference surface, which is outside surface 361 of sensor frame 36 surrounding light transmittance plate 34. Two body ground terminals 38 contacting the finger surface when light transmittance plate 34 is pressed tight to the finger are disposed around light transmittance plate 34; the body ground terminals 38 also project above the reference surface. However, the position of outside surfaces 381 of body ground terminals 38 is lower than the outside surface 341 of light transmittance plate 34. A supporter-like sensor unit holding band is used to hold sensor unit 30 on the finger. A thick material such as that used in diving wet suits is used for the sensor unit holding band, and comprises a middle layer of foam rubber.
