Abstract

A system (fig. 1) is to capture an image or scene and output image data in a device independent color space format for further processing, printing or display. An image sensor (110) along with storage memory (140) and a processor (120) is capable of storing calibration data and converting image data from a color space to a reference color space. A device profile defines a characteristic response of an image capture device. Input image data is converted into a device independent color space format based upon the device profile data.
