Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a conversion method between color spaces wherein when a color component become definite after color-space conversion, the color component is stored in a cache. SOLUTION: When a component become indefinite after conversion, a value stored in a cache is used instead of using an arbitrary default value. An obtained color edit system agrees with the expectation of a user and is "robust" in a viewpoint that it protect the user from unexpected problems occurring from using the arbitrary value for the indefinite color component.
