Abstract
Methods and apparatuses for color correction of color device for various operating conditions. In at least one embodiment of the present invention, operating under a current condition, a color correction operation that is derived from color correction operations defined for other conditions is performed on the color data. In another embodiment, a device profile for managing colors for a color device operating under one condition is interpolated from the device profiles for the color device operating under other conditions (e.g., based on the input received from a user interface according to the perception of the user or based on the measurement of a sensor). The interpolation can be based on the input received from a user interface according to the perception of the user or it can be based on the measurement of a sensor or a set of sensors. Various operating conditions for a color device (e.g., a scanner, a camera, a video camera, a printer, a display device such as a CRT monitor or an LCD display panel, a television set, or others) include chromaticity and illumination of ambient light, background color for a display device, characteristics of print media for a printer, humidity, temperature, pressure and ink level for an ink jet printer, the age of a light source for a scanner, and others.
