摘要： A pump-up circuit includes a first capacitor C1 connected to the power supply Vcc via a first change-over switch SW1 to the reference potential point or a second capacitor C2. The second capacitor C2 is charged by the voltage control circuit 45 under the control of the pump-up voltage control signal so that the capacitors C1 and C2 are charged respectively during the scanning period.

摘要： In the horizontal output circuit, a horizontal output transistor is coupled at the base with a drive pulse signal having negative peaks recurring at the horizontal periods of a television signal from a horizontal drive circuit. The emitter-collector path of the transistor is connected in parallel with a series circuit, a damper diode, and a resonant capacitor. The series circuit includes a horizontal deflecting coil and an S-distortion correcting capacitor. The collector of the transistor is connected through a flyback transformer to a DC power source. A parallel circuit is connected between the emitter of the transistor and a reference potential point. The parallel circuit is made up of a capacitor and a diode. The diodes are connected in a back-to-back manner. A series circuit including a choke coil and a capacitor is connected across the capacitor. A modulating source is connected across the capacitor of the smoothing circuit. The modulating source is controlled by a signal derived from a vertical output stage of the television receiver. The capacitor of the parallel circuit is discharged under control of the modulating source, so that the discharge current from the capacitor parabolically varies at the vertical scanning periods. The pincushion distortion is corrected through the parabolic variation of the horizontal deflecting current.

摘要： When the power key on the remote controller 12 is pressed, the electromagnetic wave is sent from the remote controller 12 to the main unit 100 of the electric device and the switch circuit 23 or 43 as the first switching means is turned on. Upon turning on of the first switching means by the power key operation, the power starts to be supplied from the second power supply 22 or 41 serving as the stand-by power supply circuit to the load circuit required for stand-by operation such as the microcomputer 24 and the light receiver 10. After that, corresponding to the first infrared signal sent from the remote controller 12, the relay 3 as the second switching means is turned on so that the commercial AC power source 1 is supplied to the main power supply circuit 2 in the main unit 100 of the electric device and the load circuit for the ordinary operation in the main unit 100 (main circuit of the device) start operation. The power is supplied from the second power supply 22 or 41 serving as the stand-by power supply circuit to the load circuit required for stand-by operation only for a short period from the start of the stand-by status after the power key operation to the ordinary operation status, and the power supply amount for the second power supply 22 or 41 serving as the stand-by power supply circuit can be only a little. When any power supply other than the commercial AC power source 1 such as a solar battery 221 is used as the second power supply, the stand-by power of the electric device in stand-by status can be reduced to zero.

摘要： A current resonance power supply circuit resonates the primary winding L61 of the switching transformer 64 and the current resonance capacitor C2I by turning on and off the switching elements 61 and 62 and obtains high frequency output from the secondary winding L62 of the switching transformer 64 according to such resonance. With a capacitor whose capacity increases as the operation frequency of the switching elements 61 and 62 decreases used as the capacitor C2I above, the out-of-resonance phenomenon hardly occurs upon a sharp drop of the AC power voltage or a quick increase of the load.

摘要： After analog-to-digital conversion, a luminance signal 103 and a chrominance signal 109 are stored in a line memory circuit 128. Such stored signals are read out of said line memory circuit, using a read clock 124 obtained by parabolically modulating a read frequency with both the horizontal period and the vertical period. The read-out digital signal is again converted into an analog luminance signal 132 and analog color difference signals 135, 136 by digital-to-analog conversion. By this procedure, inner pincushion distortion or inner barrel distortion is corrected. Since such distortion is corrected by modulating an image signal itself by digital processing, no circuit drift due to the conventional analog correction occurs and no analog circuit design such as troublesome setting of parts constants is required.
摘要翻译：在模数转换之后，亮度信号103和色度信号109被存储在行存储器电路128中。使用通过抛物线调制读取频率获得的读时钟124从所述行存储器电路中读出这样存储的信号具有水平周期和垂直周期。读出的数字信号通过数模转换再次转换为模拟亮度信号132和模拟色差信号135,136。通过该过程，校正内枕形失真或内筒失真。由于通过数字处理调制图像信号本身来校正这种失真，所以不会发生由于常规模拟校正引起的电路漂移，并且不需要模拟电路设计，例如部件常数的麻烦的设置。
