    • The present invention makes it possible to let a user arbitrarily and easily see any other scene than himself or herself in his or her view (the scene seen from any other moving body than him or her). In a display device (an image pickup and display device 1 or a display device 40), specification information is generated to specify a specific image pickup device of outer image pickup devices (the image pickup and display device 1 or and image pickup device 30), and image data are received from the image pickup device specified by the specification information and are displayed. As an outer image pickup device, for example, and image pickup device wore by some other person, image pickup devices set at a car, an electric train, and the like, or further mage pickup devices set at an animal, a bird, and the like are supposed. Image data picked up by these image pickup devices are transmitted to the display side and the image display is carried out in the display device. Thus, a user of the display device can see images of viewing scenes watched by other people, for example, images of viewing scenes seen from a car, an electric train, and the like, or images of viewing scenes seen from an animal, a bird, and the like.

    • The present invention enables to enhance a processing performance in analyzing a bit stream of decoding a variable-length code to be successively processed. The present invention provides an MPEG video decoder for decoding an MPEG video stream including: a pre-purser 3 (bit stream divider) for detecting a slice start code of Slice layer and dividing a bit stream into two sub streams; video decoders 9 and 10 for decoding the sub streams separately from each other; a memory controller (memory interface) for combining with consistency the decoded data from the video decoders 9 and 10; and an external memory 4.

    • A phase difference-detecting apparatus for detecting a relative distance between a pair of focused images obtained from a subject luminous flux passed through an objective lens to thereby judge a focusing state of the objective lens. The apparatus includes a pair of signal generating sections which receive the subject flux and provide first and second time series signals. A switching-capacitor integrator is provided including a plurality of capacitive elements and switching elements for intermittently connecting the capacitive elements to each other, and for receiving the first and second time series signals. A control device compares the sizes of the first and second time series signals with each other to thereby generate a control signal corresponding to a relation of size between the first and second time series signals. The switching elements are controlled on the basis of the control signal to cause the switching-capacitor integrator to generate an electric charge corresponding to an integrated value of an absolute value of a difference between the first and second time series signals, and to cause the switching-capacitor integrator to generate, as a correlation value, an integrated value on the basis of the first and second time series signals in predetermined numbers whenever the quantity of relative movement is changed. The switching-capacitor integrator includes a gain control including a plurality of switchable capacitances.
    • 一种相位差检测装置,用于检测从通过物镜的目标光束获得的一对聚焦图像之间的相对距离,从而判断物镜的聚焦状态。 该装置包括一对信号产生部分,其接收对象通量并提供第一和第二时间序列信号。 提供一种开关电容积分器,其包括多个电容元件和用于间歇地将电容元件彼此连接的开关元件,以及用于接收第一和第二时间序列信号。 控制装置将第一和第二时间序列信号的大小彼此进行比较,从而产生对应于第一和第二时间序列信号之间的大小关系的控制信号。 基于控制信号控制开关元件,使开关电容积分器产生与第一和第二时间序列信号之间的差的绝对值的积分值相对应的电荷,并使开关元件 电容积分器,每当相对移动量发生变化时,根据第一和第二时间序列信号,以相关值生成预定数量的积分值。 开关电容积分器包括包括多个可切换电容的增益控制。
