Title: Color image processing method
Inventor: YANO TAKANORI
IPC: G03G15/01
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To realize efficient color reproduction with high fidelity by defining in advance a representative point of a color value on a gamut boundary in the case that part of color image information lies outside of the gamut (color reproduction area) and determining a compression destination through the use of the representative point. SOLUTION: First, a color value is entered with respect to each pixel. Color space conversion processing that converts the entered color value into a color coordinate on an isochromatic space is conducted. Furthermore, whether the color information is within the gamut or at its outside is discriminated. When the information is decided as being inside the gamut, no special processing is conducted. However when the information lies outside of the gamut, the information is defined by a set of color values (representative points) on a gamut boundary surface, and a range of the representative points as the retrieval object is limited in the boundary surface. The color value of the gamut compression destination is calculated by using the representative points and converted into a coordinate in a color space of an output destination, and image outputting is executed.

Title: Magnetic head
Inventor: GOTO SATORU
IPC: G11B5/265
Filed: 1986-08-09
Abstract: PURPOSE:To form symmetrical recording magnetization by supplying recording currents asymmetrically to recording coils divided into two parts and compensating the asymmetry of the recording magnetization by the interference of an erasing magnetic flux with recording magnetic fluxes. CONSTITUTION:Since a current supplying circuit 20 supplies the recording currents asymmetrically to the coils 7, 8, the magnetic energies generated by the coils 7, 8 are different from each other. The recording magnetic flux A' in the same direction as the direction of the erasing magnetic flux E, therefrom, decreases and the recording magnetic flux B' in the direction different therefrom increases. Since the erasing magnetic flux E in the specified direction by an erasing head 2 exists at this time, the magnetic flux A' increases and the magnetic flux B' decreases if the magnetic flux E interferes with the magnetic fluxes A', B'. The interference of the magnetic flux E is thereby eventually cancelled so that the magnetic fluxes A', B' are equal to each other in the directions different from each other. The asymmetry of the recording magnetization is compensated by the interference of the erasing magnetic flux with the recording magnetic fluxes in the above-mentioned manner; therefore, the symmetrical magnetization is obtd.

Abstract: PURPOSE: To prevent the occurrence of distortion by providing a switching means to reduce the noise of an input signal independently of the level. CONSTITUTION: When a reception signal in the high level is inputted to an input terminal 12, changeover switches 114 and 120 are connected to contacts 114a and 120a respectively to apply the automatic gain control to a first variable attenuation means 14, and the input signal is attenuated; and then, distortion doesn't occur when it is inputted to a first amplification means 28. The output of this means 28 passes a second variable attenuation means 34 having a maximum extent of attenuation and is supplied to an output terminal 42 by a low- distortion and high-output high frequency amplifier 36. The output signal of the terminal 42 has a fixed level set by a variable resistor 84.  When a reception signal in the low level is inputted, switches 114 and 120 are connected to contacts 114c and 120a respectively, and a minimum extent of attenuation is given to the means 14, and the automatic gain control is applied to the means 34. Thus, the input signal is not attenuated by the means 14 and passes the means 28 and is subjected to automatic gain control by the means 34 and is amplified by the means 36 and is outputted through an output terminal 42. Consequently, the noise figure is satisfactory.
