Title: Magnetic recording circuit
Inventor: EGUCHI TAKEO
IPC: G11B5/09
Filed: 1979-04-10
Abstract: PURPOSE:To improve characteristics with simple constitution by supplying an input signal to a differential current changeover circuit, by supplying its output to both terminals of a winding, and by connecting a power supply to the middle point of the winding to drive a head by a current flowing the winding. CONSTITUTION:Transistors 11 and 12 are of differential type and constitute a switching circuit. Once a binary signal to be recorded is supplied between input terminals 1a and 1b, transistors 11 and 12 are alternately turned ON or OFF, As the result of turning transistor 11 or 12 ON, current is flowed backward through winding 40 to invert the magnetization direction of magnetic gap 44, recording a signal on a magnetic tape. The current flowing through winding 40 is determined by a current flowing through transistor 13 and even if the signal supplied between input terminals 1a and 1b would be rounded slightly, a correct signal is reproduced as far as switch points of transistors 11 and 12 are unchanged. Thus, characteristics can be improved with the simple constitution.

IPC: H04N19/59
Filed: 1994-03-15
Abstract: PURPOSE:To perform nearly horizontal interpolation and to reduce misdecision making even when an image has a high horizontal spatial frequency by detecting the horizontal spatial frequency at the periphery of an aimed pixel and selecting one of plural interpolation direction determination steps on the basis of the detected spatial frequency. CONSTITUTION:A spatial frequency detecting means 3 detects the horizontal spatial frequency at the periphery of the aimed pixel and outputs spatial frequency information 9. An interpolation-directional composing means 4 puts a 1st interpolation direction signal 7 suitable for a high horizontal spatial frequency and a 2nd interpolation direction signal 8 suitable for a low horizontal spatial frequency together by using spatial frequency information 9. An interpolation pixel generating means 5 generates an interpolation pixel signal 11 from an image signal 6 by using the obtained interpolation direction composite signal 10. Consequently, an interpolation line is determined by selecting the interpolation direction determination step adaptively to the horizontal spatial frequency at the periphery of the aimed pixel, so while an interpolation miss at the time of the high spatial frequency is reduced, the nearly horizontal interpolation is enabled.
