1. A color calibration system comprising:
- a processor for receiving and transmitting data;
a single sensor, operatively coupled with said processor, includinga first multi-pixel area integrating sensor which detects raster-scanned emissive color energy and in response provides first color sampling data to the processor, anda second multi-pixel area integrating sensor which detects reflective color energy and in response provides second color sampling data to the processor; and
a color output device which is calibrated by the processor in response to data provided by at least one of the first and second sensors.

Abstract
A color calibration system comprises a processor for receiving and transmitting data. A first sensor coupled to the processor detects emissive color images for providing first color sampling data to the processor. A second sensor coupled to the processor detects reflective color images for providing second color sampling data to the processor. A color output device coupled to the processor is calibrated in response to data generated by at least one of the first and second sensors.

10. A method for calibrating a color imaging system comprising the steps of:
-
sampling color image data, using a sensor including both an emissive transducer and a reflective transducer, from an image source; selecting from between said emissive transducer and said reflective transducer based on the image source; storing said image data to a color space; transforming the color space to a device profile; and generating a calibrated image output as defined by the device profile. - View Dependent Claims (11, 12, 13)
