  • Patent number: 7330411
    Abstract: The present invention aims at providing an inexpensive optical information storing device that produces reduced cross talk. An optical information storing device has a cyclic data output circuit 14—1 that outputs cyclic data in which values are repeated every 5 bytes, and an EXOR circuit 14—2 that calculates the exclusive-OR (EXOR) of recording data input thereto via a buffer 14—5 and the cyclic data and inputs the calculation result to an RLL modulation circuit 14—3 as data to be recorded.

  • Publication number: 20080007784
    Abstract: There is disclosed technology of a color conversion definition for converting coordinate points in a color reproduction area of a printer into coordinate points in a color reproduction area of a print. This technology makes it possible to increase the degree of freedom of designation for K-plate restraint conditions of print, and also permit to widely take the color reproduction area within the range of ink total amount limitation. The vertex of K is established to be points (C, M, Y, K)=(CSH, MSH, YSH, KSH) in which K-plate restraint conditions are designated. There is created a virtual device profile tracing the color reproduction area of a print on not only edge lines coupling W with C, M and Y, and edge lines coupling K with R, G and B, but also diagonals edge lines coupling W with R, G and B, and diagonals edge lines coupling K with C, M and Y.

  • Publication number: 20070296988
    Abstract: A color reproduction range excellent in a printing step on an L*a*b* color space is extracted using a B2A1 profile and an A2B1 profile in this order, a dummy RGB gamut for a virtual device obtained by tracing the color reproduction range is created, and, using the dummy RGB gamut, gamut conversion for converting a gamut of a printer as an RGB device into a dummy RGB gamut is performed.

  • Publication number: 20070236762
    Abstract: Trimming is automatically performed on an image by inferring a person and a background in which the photographer of the image has interest. Facial images FP1 and FP2 are detected in a whole image P, and the vertical direction of the whole image P is judged based the facial images FP1 and FP2. Further, processing is performed using the information about the vertical direction to discriminate whether the composition of the whole image P is portrait-mode composition or landscape-mode composition. If it is judged that the facial image FPl is positioned on the lower side of the whole image, and if a composition discrimination unit discriminates that the composition of the whole image P is landscape-mode composition, trimming is automatically performed using a trimming frame TG10 that has portrait-mode composition.

  • Publication number: 20050206929
    Abstract: There is disclosed a color conversion definition creating method of creating a color conversion definition for converting coordinate points in a color reproduction area of a printer into coordinate points in a color reproduction area of a print. A profile of a virtual device, which has a color reproduction area tracing the color reproduction area for printing, is created. Created is a first color conversion definition for converting coordinate points in the color reproduction area of the printer in the first RGB color space into coordinate points in the color reproduction area of the virtual device in a second RGB color space depending on the virtual device. Created is a second color conversion definition for converting coordinate points in the color reproduction area of the virtual device in the second RGB color space into coordinate points in the color reproduction area for printing in the CMYK color space.

  • Publication number: 20050206926
    Abstract: In a color conversion definition process, first, a profile of a virtual device having a color reproduction range that well simulates a color reproduction range of a printing system is produced. A first color conversion is then defined so as to convert a coordinate point in a color reproduction range of a printer expressed in a first RGB color space to a coordinate point in the color reproduction range of the virtual device expressed in a second RGB color space dependent on the virtual device. A second color conversion is then defined so as to convert a coordinate point in the color reproduction range of the virtual device expressed in the second RGB color space to a coordinate point in the color reproduction range of the printing system expressed in the CMYK color space. The resultant coordinate point represents a color very similar to a color represented by the printing system.

  • Patent number: 6026068
    Abstract: A constant linear velocity control (CLV control) for controlling a spindle motor so as to set a linear velocity in a track circumferential direction to be constant and a constant angular velocity control (CAV control) for controlling the spindle motor so as to set a rotation of a medium to be constant are switched and controlled for a change in position in the radial direction of the medium of a pickup in accordance with a detection result of the medium loaded. In the switching control, selection information of the CLV control and the CAV control is previously registered in accordance with the kind of medium and the CLV control or the CAV control is selected in accordance with the corresponding selection information obtained from the detection result of the medium.

  • Patent number: 5689147
    Abstract: A brushless motor comprising a stator core having a plurality of tooth portions disposed peripherally at intervals, coils wound in a required manner on a plurality of tooth portions, an annular rotor magnet disposed in opposition to the stator core and having N poles and S poles alternately disposed, and a position detecting sensor for detecting the rotating angular position of the rotor magnet. The stator core is formed by laminating an anisotropic steel sheet in which the easily magnetizable axis of the crystal is in a specific direction.
