Title: Method and device for generating latin square
Inventor: ITO TORU
IPC: G06F17/10
Filed: 2000-11-01
Abstract: PROBLEM TO BE SOLVED: To solve such problem that a 3rd party easily estimates a Latin square to be used since a conventional Latin square generating method uniquely determines a Latin square to be generated next. SOLUTION: An existent Latin square R' is set in an array 9 for Latin square storage and a symbol (m) as an element of the existent Latin square R' is moved to an array 17 for Latin square replacement to generate a new Latin square R". For example, when the existent Latin square R' is rotated by 90 deg. and moved to the array 19 for Latin square replacement, a symbol E11 of the array 9 is moved to E13 of the array 17 first, a symbol E12 to E23, a symbol E13 to E33, a symbol E21 to E23, and a symbol E33 to E31 to move the symbols at the respective positions of the array 9 to the array 17 for Latin square replacement thus completing the replacement by the rotation.

Filed: 2000-11-14
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for processing an image capable of satisfactorily color reproducing both a natural image and a CG image even when the natural image and the CG image are mixed in the input color image. SOLUTION: A inner and outer gamut judging unit 2 of a position information acquiring device 1 judges whether the input color image signal is out of an output gamut or not. If the signal is judged to be out of the output gamut, a distance information acquiring unit 3 calculates a distance from the surface of the output gamut to the input color image signal. A converter 4 updates an evaluation function according to the position information such as the distance or the like calculated by the unit 3, and converts the input color image signal into the image signal in the output gamut by using the updated evaluation function. For example, for the color having a large distance, the color contains many high chroma, and hence the function may be updated so as to preserve the chroma and may be converted.  When the output gamut is not compressed and output, the input color is preserved as it is, and satisfactorily reproduced.
