  • System and method for color space conversion
    Patent number: 5818613
    Abstract: A system and method for converting a color represented in a first color space to the color represented in a second color space uses a constant hue algorithm. The constant hue algorithm is used to compensate invalid colors in the second color space obtained as a result of the conversion. The constant hue algorithm determines a compensation factor that, in effect, blends the invalid color with pure grey until the invalid color becomes a valid color in the second color space. The compensation factor is optionally stored with the valid color in the second color space so that the original color in the first color space can be subsequently recovered.
