    摘要： An information recording and reproduction apparatus for a magneto-optical medium includes a synchronizing signal generation circuit for generating a synchronizing signal to provide a pulsed laser beam at the time of reproduction according to an internal clock obtained from a reproduction signal. The laser beam is driven on/off according to the synchronizing signal at the time of reproduction to have the laser spot on the signal plane prevented from being enlarged, so that the reproducible domain is smaller than the domain of when a laser beam is continuously emitted. In reproduction, an optical superresolution method is applied simultaneous to provision of a pulsed laser beam to allow reproduction of higher density. An external synchronizing signal generation circuit for generating an external synchronizing signal according to a wobble on a surface of a recording medium can be used instead of a synchronizing signal generation circuit according to an internal clock.

    摘要： In a frame transfer CCD image sensor, the frame rate is improved while suppressing a smear component in the case that the image from a part of the imaging portion is used. A smear evaluation circuit obtains the smear component of each line of image signal V(j) of a center area which is an image extraction target from an accumulated value of preceding lines of image signal. Here, contribution of the smear component from the preceding read area of the center area is estimated based on the image signal of the first line of the center area, without using the accumulation of the image signals of the preceding read area. This estimate value is set in a line memory as a smear component initial value and an accumulating process for each line of the center area begins. Thereby, the read of the image signal of the preceding read area is omitted and thus the frame rate is improved.

    摘要： A system for transmitting image data on a telephone network or equivalent, which typically includes video or visual telephones as apparatus of sending part and receiving part. In the video telephone of sending part, when an image data sending key is operated, a DTMF signal generator included in a modem is started to operated and a specified DTMF signal, for example, DTMF-A signal or DTMF-B signal is sent as a signal DTMF-DTA to a telephone circuit through a network control unit for approximate 300 milliseconds. Succeedingly, in spite of presence or absence of a responsive signal from the video telephone of receiving part, a non-signal state is formed for approximate 75 milliseconds, immediately thereafter, the image data is sent from the video telephone of sending part at a transmission speed of 4,800 bps or 2,400 bps. In the video telephone of receiving part, when the signal DTMF-DTA, that is, the above described DTMF-A signal or DTMF-B signal is continuously received for approximate 250 milliseconds, a modem thereof is started at 4,800 bps or 2,400 bps, and the image data being sent from the video telephone of sending part is received.
