    • When a connection mode change setting instruction input entered by a user is supplied to the control unit 20, the control unit 20 controls the IEEE 1394 I/F circuit to set the value of oPCR and iPCR of an electronic apparatus for forming a channel so that the channel between target electronic apparatus is formed in the connection mode instructed by the user. Thereby, a channel between electronic apparatus is formed flexibly and an information output apparatus that is capable of forming a convenient electronic apparatus network is provided. One electronic apparatus connected to the digital bus inquires of an electronic apparatus connected to the digital bus whether it is a monitor apparatus (first receiving apparatus) that receives the data mainly through a channel formed in the broadcast connection mode or not, and channels connected in the broadcast connection mode are allocated to monitor apparatus respectively. A receiving apparatus other than the monitor apparatus forms a channel of the PtoP mode avoiding the channel of the first connection mode allocated to the first receiving apparatus, and receives supply of the data. As the result, a transmission line using method, an information transmission system, and an electronic apparatus that are capable of utilizing a plurality of channels on the digital bus efficiently, and capable of providing the convenient digital content using environment are realized.

    • In an apparatus for detecting amounts of relative motion of a picture expressed by a digital video signal, between successive fields of the signal, a fixed set of picture element positions are designated as respective representative points in each field of the video signal. For each representative point, the signal level value for that point during a preceding field is compared with each of a successive of picture element values in the current field, within a corresponding comparison interval which extends prior to and subsequent to the position of that representative point in the field. In addition, a corresponding value of relative distance between each picture element for which a result is obtained and that representative point is derived as a binary value, and the result is cumulatively stored with corresponding results for other representative points in an address of one of a plurality of memory sections, with the particular memory section being assigned in accordance with the state(s) of one or more high-order bits of the corresponding relative distance value and the address being assigned in accordance with the remaining low-order bits of that distance value.

    • An image pickup apparatus has a CMOS image pickup device. An image pickup area of the image pickup device includes a regular image pickup area and an environment detection area. A flicker detector of the image pickup apparatus detects a frequency component in an image signal provided by the environment detection area. Based on the detected frequency component, a system controller of the image pickup apparatus determines whether or not the image pickup apparatus is in a flicker causing environment. If it is in the flicker causing environment, a timing generator of the image pickup apparatus sets an exposure time for the regular image pickup area so as to suppress flicker. At this time, no change is made in an exposure time for the environment detection area, so that a flicker causing environment may continuously be detectable.
    • 图像拾取装置具有CMOS图像拾取装置。 图像拾取装置的图像拾取区域包括常规图像拾取区域和环境检测区域。 图像拾取装置的闪烁检测器检测由环境检测区域提供的图像信号中的频率分量。 基于检测到的频率分量,图像拾取装置的系统控制器确定图像拾取装置是否处于闪烁引起的环境中。 如果处于闪烁引起环境中,图像拾取装置的定时发生器设置常规图像拾取区域的曝光时间,以抑制闪烁。 此时,环境检测区域的曝光时间没有变化,从而可以连续检测闪烁引起的环境。
