摘要:
A video signal obtained by a solid-state image pickup device is supplied to a display apparatus to display an image. The number of the pixels of the solid-state image pickup device is smaller (e.g., 1/4) than that of the screen of the display apparatus. The transfer clock of the solid-state image pickup device is so controlled that the video signal output therefrom corresponds to an image displayed at the region of 1/4 of the reproducing screen. The video signals from four solid-state image pickup devices are compounded so as to display an image composed of four divided images on one screen. A synchronizing signal which is a reference for the transfer clock is transmitted from the display apparatus so as to synchronize the four video signals. In another mode, the transfer clock is so controlled as to enlarge a video signal which corresponds to an image for the 1/4 region of the reproducing signal and display the image on the entire part of the reproducing screen.

The horizontal synchronous signal and the vertical synchronous signal included in a composite synchronous signal which is output from one TV camera are separated from the composite synchronous signal. A plurality of TV cameras are controlled on the basis of the horizontal synchronous signal and the vertical synchronous signal so as to produce synchronized video signals from the plurality of TV cameras. These synchronized video signals are easy to compound. In the blanking period of the vertical synchronous signal, the rise period of the synchronous signal is 1/2 of the period of the vertical synchronous signal. Pulses are eliminated alternately in the blanking period by a half killer circuit including a counter and a decoder and having a simple structure, thereby generating a horizontal synchronous signal appropriate for driving the TV cameras. The counter composed of Johnson counters connected in multiple stages reduces the amount of current flowing to the counter, thereby eliminating the deleterious influence on the TV cameras.

In solid-state image sensing apparatus including a frame transfer type CCD 10 as a solid-state image sensing device, charges stored in a light receiving portion 11 are once discharged externally in each vertical scanning period. Thereafter, newly stored charges are read as signal charges in a storage portion 12 in a vertical blanking period. Timing to discharge the charges is then set in accordance with an exposure state of the CCD, so that an exposure period is shortened and expanded. The width of a single shortening and expansion of the exposure period is variable. Particularly, when the charge discharging timing enters in the vertical blanking period, and the exposure period becomes significantly short, the charge discharging timing is set in a unit of a shorter period than one horizontal period of an image signal. This enables a uniform ratio of variation of the exposure period and prevention of unnatural changes of luminance on a reproduced picture.

A first digital processor (13) generates luminance data Y and color difference data U, V, using image data D1. The processor (13) further generates separated luminance data Y1, Y2 by halving the luminance data Y, and generates a compound color difference data C by combining the color difference data U, V for output. An JPEG encoder 13 compresses the separated luminance data Y1, Y2 and the compound color difference data C to generate compressed luminance data y1, y2 and compressed color difference data c. A modulator 15 modulates the compressed luminance data y1, y2 and the compressed color difference data c to generate luminance modulated signals m1, m2 and color difference modulated signal mc. A recording/reproducing section 16 records the luminance modulated signals m1, m2 and the color difference modulated signal mc in parallel onto the first to third recording tracks of a magnetic tape (20).
摘要:
Solid image pickup elements are used in televison cameras, for example. A solid image pickup element is capable of receiving light and generating a picture signal corresponding to the light. For this purpose, the solid image pickup element has a picture area formed of photoelectric converters arranged in a two-dimensional matrix and generated information charges corresponding to light incident on the picture area. The information charges obtained at the picture area are transferred to and stored in the store area, vertical column by vertical column. At that time, the charges more than the number of the vertical photoelectric converters of the picture area are transferred to the store area. The transfer in the absence of the corresponding photoelectric converters is thereby performed so that the smear charges are stored in the store area. With this information of the smear charges being stored, the smear charges are eliminated from the information charges.
摘要:
A data transmission system having a plurality of stations and bus structure connected among the stations for sending an information data or an answer back data in a packet from one station to another station through the bus structure. Each station has a receiver which receives the packet and detects that the packet of information data is directed to the station by identifying the address data. If it is so detected that the packet is directed to this station, an acknowledge signal is produced. A carrier sensor is provided for producing a presence signal indicative of the presence of the packet on the bus structure. A counter starts to count time when the presence signal disappears, and produces first and second time-up signals after the lapse of first and second predetermined times, respectively, provided that the first predetermined time is shorter than the second predetermined time. A transmitter prepares the packet of answer back data in response to the receipt of the acknowledge signal and transmits the prepared answer back data after the counter has counted the first predetermined time and before the end of the second predetermined time.
