IPC: H04N9/68
Filed: 1988-01-19
Abstract: PURPOSE:To obtain the good improvement effect of a contour by executing sample-holding to the central position of the contour, improving a wave form and preventing time lag caused by the size of the wave form from being generated. CONSTITUTION:A luminance signal inputted from a terminal 1 is differentiated by a differentiating circuit 2 and a color difference signal (d) inputted from a terminal 17 is differentiated by a differentiating circuit 3. Then, they are inputted to a control signal generation circuit 4. In the circuit 4, a control signal (i) is obtained by adding them with the aid of an adder 9, differentiating them with the aid of a differentiating circuit 10 and wave-form-shaping them with the aid of a wave form shaping circuit 11 after full-wave-rectifying two input by full-wave rectifying circuits 7 and 8. Thus, when the luminance signal is changed, the information of the luminance signal is used and the control signal is generated by the change of the color difference signal when the luminance signal is not changed. Due to that, regardless of the size of the signal change, the sample-holding is executed to the center of the contour and the contour can be improved without generating a color spot.

Abstract: PURPOSE:To perform high-accuracy position detection by using a thin and long magnetic member whose sectional area perpendicular to the lengthwise direction is maximum at both ends, decreases to the center, and is maximum at the center part. CONSTITUTION:Pieces of magnetic flux 24 and 25 penetrate thin and long magnetic members 20 and 21 of a closed magnetic circuit 23 from the S poles of permanent magnets 3 and 4 to the N poles and leak magnetic flux 26 from the members 20 and 21 flow inside the circuit 23. The sectional area of the members 20 and 21 perpendicular to their lengthwise direction is maximum at both ends, decreases with the distance from the permanent magnets 3 and 4, and is minimum at the center part P1. The decrease in the sectional area accelerates the leak of the magnetic flux, which leaks effectively even at distance from the permanent magnets 3 and 4. Consequently, the linearity of a magnetic detector 6 which indicates the relation between the magnetic intensity of a magnetic field established with the leak magnetic flux nearby the inside surface 20a of the member 20 and respective lengthwise positions of the member 20 is improved. Then, the voltage output of the detector 6 is amplified 11, filtered 12, and A/D-converted 14, and the result is processed by a microprocessor 15, so that high-accuracy detection is possible.
