摘要： PURPOSE:To obtain excellent correction effect by using a signal just after and just before the start so as to replace a signal changing at a contour part with them. CONSTITUTION:A video signal input A inputted from an analog input terminal 10 is differentiated by a differentiating circuit 2 and a waveform B is obtained by taking the absolute value of the differentiated signal. Moreover, a waveform C is obtained by differentiating the waveform B by a differentiating circuit 4. The waveform C has a positive value from the change start point of the signal till the middle of the contour (before the displacement) among the video contour of the video image and has a negative value from the middle till the end point of the change (after the displacement). The signal is compared with a prescribed threshold level shown in dotted lines in the waveform C. The waveform C is detected by a waveform shaping circuit S to obtain detection signal waveforms D, E and when the positive value is discriminated from the contour part by using the waveform D and the negative waveform E, the position of the contour and the width are coded and the result is recorded in a memory 6 together with a video signal from a delay circuit 12 as contour detection information. Thus, color blurring and fog are improved.

摘要： PURPOSE:To attain contour correction and time axis conversion at the same time by using a means generating a clock synchronously with an external video signal coupling with an input video signal synchronizingly so as to convert a time axis and detecting the contour information of an input video signal so as to change locally the period of a write or a readout clock. CONSTITUTION:A voltage controlling the oscillating frequency of a voltage controlled oscillator(VCO) 7 is a voltage resulting from the addition of a voltage in response to a change in an input signal to an output voltage of a phase comparator circuit 8 and a clock with a different period from that of a readout clock is obtained locally as a frequency of the write clock. Then a control voltage superimposed with an AC voltage reflecting its contour component is fed to the VCO 7 resulting that the period of a generated clock is changed at the contour part. Thus, the data interval of the contour part is subjected to time compression at the write and the contour correction effect making the waveform of the contour part steep is obtained and since the write read of the memory are implemented by the clock synchronously with the time fluctuation of the input signal without having any time fluctuation, the time axis is corrected at the same time.

摘要： PURPOSE:To improve picture quality and to facilitate the combination with other devices by mounting three optical heads on one carriage and recording or reproducing signals of R, G and B or three kinds of component signals obtained from them corresponding to respective heads. CONSTITUTION:A television camera 31 outputs component signals 32a-32c of R, B and G and a composite synchronizing signal 32d, which is added by addition stages 34a-34c after band control is performed by LPFs 33a-33c; and FM signals are obtained by FM modulation stages 18a-18c and applied to optical heads 2a-2c and they are modulated by a semiconductor laser and recorded. When reproduction is performed, FM signals are extracted by HPFs 23a-23c from optical head outputs 4a-4c and demodulated by FM demodulation stages 24a-24c to obtain playback signals 35a-35c. Consequently, a recorded FM signal has no chrominance signal at the low frequency side, so the band of the LPF 35a, etc., set widely correspondingly and a playback signal of this picture quality is obtained without dot disturbance nor cross color.

摘要： PURPOSE:To ensure the stable servo control, by obtaining the maximum distortion of a disk from a current flowing to an actuator of a pickup, then setting the gain and the frequency characteristics of a servo system so as to remain the obtained maximum distortion within the residual allowance value. CONSTITUTION:The relative position between a disk and a pickup is detected 1 and amplified 2, and phase compensations 3-3'' are carried out via analog switches 13-13'' to drive 4 an actuator 5. The output of a variable frequency oscillator 7 is multiplied 8 by the current flowing to the actuator 5 and detected by a resistance 15. The output of this multiplication is filtered 9 and wave- detected 10 and supplied to a CPU16 after an A/D conversion 11'. The frequency of the oscillator 7 is counted 12 digitally and supplied to the CPU16. The CPU16 obtains the maximum distortion of the disk from each of above-mentioned inputs and then controls the amplifier 2 and phase compensators 3-3'' only when the maximum distortion exceeds the threshold value. This ensures the stable servo control.

摘要： PURPOSE:To attain detection even for the dropout exsisting in a range from a sink chip to a white peak, by detecting the difference signal between the video signal preceding by a scan period and the present video signal. CONSTITUTION:An input FM signal 1 is demodulated through an FM demodulating circuit 7 and applied to a low pass filter 8. The output passed through the filter 8 is applied directly to a minus input terminal of a differential amplifier 11, and at the same time the output is applied to a plus input terminal via a minus horizontal scan period delaying circuit 10. The output 12 of the amplifier 11 is shaped by a pulse shaping circuit 5 to obtain a dropout detection pulse 6. The degree of correlation is high between the demodulated video signal and the video signal preceding by a scan period, and both video signals have substantially an equal waveform excepting for the dropout period. When a dropout arises, the amplifier 11 delivers the positive pulse, and this positive pulse is shaped to obtain a dropout detection pulse.
