摘要： PURPOSE:To greatly reduce the scale of a circuit, by realizing the use of a large-capacity frame memory by means of a buffer memory which stores the coded memories of a horizontal video period. CONSTITUTION:Both the horizontal and vertical periods of a color TV picture signal of a single system are divided for example into 4 parts respectively to display a picture. An A/D converter 35, etc. encodes the TV input signal into a digital signal, and buffer memories 84-87 are divided into 4 parts in terms of the time axis for the 1H period of the coded signal to be stored. The contents of these 4 memories are written in paralled into 4X4 frame memories 69-76 and then read out in parallel from these frame memories. The read-out coded signals of 4X4 systems is subjected to D/A conversions 45-47, and the analog signals are applied to a TV picture receiver.

摘要： PURPOSE:To combine the contents of the fields received a double scan and to reduce the image distortion, by converting a video signal and a signal obtained by a 1-field delay to the video signal into the double frequency signals and extracting the signals alternately and with every horizontal scan out of both signals. CONSTITUTION:An input signal S is applied to an A/D converter 2 and a synchronous separating circuit 28, and the video signal given from the converter 2 and the signal obtained by delaying the video signal by a field through a 1V delaying circuit 9 are converted into double frequency signals through double scanning frequency converting circuits 7 and 8 to be added together by an adder 11. The output of the adder 11 is applied to a D/A converter 18, an H/2 delaying circuit 10 and an adder 11 respectively. The outputs of the circuit 10 and the adder 12 are applied to contacts A and B of a switch 17, and the output of the switch 17 is applied to a converter 18. The switch 17 is switched by the synchronous signal separated through the circuit 28 and a discrimination signal ID produced by a field discriminating circuit 29, and a double frequency signal 2fC given from a PLL circuit 30 is applied to the circuit 10. Then a double scanning signal of combination of fields is delivered through the converter 18.

摘要： PURPOSE:To make the number of scanning lines double to improve resolution, by controlling the variable delay means, which delays the video signal, by the horizontal deflection means which is operated synchronously with the double of the horizontal synchronizing signal. CONSTITUTION:The input video signal is applied to horizontal oscillating circuit 3, which oscillates at period H/2, through synchronizing separating circuit 1 to control oscillation. Field detecting circuit 11 detects an even field and flows a current to the deflection coil during this period by current switch 12 to improve interlace. Variable delay line control circuit 13 which is operated by pulses synchronized with the color subcarrier controls variable delay line 14 where the video signal is input, and the video signal has the time base compressed. This signal is reconstituted to a video signal by analogue switch 15 to drive Braun tube 21. Consequently, the video signal of the 1H period is compressed to output the signal twice, so that resolution can be improved.

摘要： PURPOSE:To increase the scandensity and then the resolution by providing several units of electron guns within the Braun tube and giving the simultaneous scanning with the relative positions kept the electron beams radiated from these electron guns and with variation of the beam direction. CONSTITUTION:Two electron guns 11a and 11b are stored within the Braun tube, and the electron beams radiated from these guns are deflected via deflecting coil 12 to reach fluorescent screen 13. As a result, two spots can be displayed simultaneously on screen 13 by the radiated two beams. That is, the spot loci are produced as shown by the solid and dotted lines in the figure. Thus th resolution can be increased without using the high-speed video amplifer, the large-power deflecting device and others.

摘要： PROBLEM TO BE SOLVED: To enable an optimum display state to be maintained at all times by correcting the display state of an image to a state of an initial regulating time. SOLUTION: Initial reference data relating to a beam trajectory is held in a memory unit 53, and an amount of change of the beam trajectory from an initial regulating state is obtained by comparing the held initial reference data with data relating to the beam trajectory detected by an index electrode. A correction quantity calculator 51 calculates an amount of correction for returning a display screen to the initial regulating state based on the obtained amount of change of the beam trajectory. An input signal processing unit 54 and a deflection control unit 55 control the beam trajectory and the input signal based on the amount of correction so that the display screen approaches the state of the initial regulating stage. Thus, image distortion is corrected to the state of the initial regulating time, and the optimum display state can be always maintained. COPYRIGHT: (C)2004,JPO
