Abstract
In the color imaging system, multiple rendering devices are provided at different nodes along a network. Each rendering device has a color measurement instrument for calibrating the color presented by the rendering device. A rendering device may represent a color display in which a member surrounds the outer periphery of the screen of the display and a color measuring instrument is coupled to the first member. The color measuring instrument includes a sensor spaced from the screen at an angle with respect to the screen for receiving light from an area of the screen. A rendering device may be a printer in which the measuring of color samples on a sheet rendered by the printer is provided by a sensor coupled to a transport mechanism which moves the sensor and sheet relative to each other, where the sensor provides light from the sample to a spectrograph. The color measuring instruments provide for non-contact measurements of color samples either displayed on a color display, or printed on a sheet, and are self-calibrating by the use of calibration references in the instrument.

42. A digital image processing system comprising:
-
a first sensor that captures at least one two-dimensional image of a scene in a plurality of channels to provide digital image data representative of said two-dimensional image; at least one video display for rendering said two-dimensional image in color and displaying a user interface enabling control of said system and expression of preferences for image processing, wherein said user interface provides a graphical representation of functions selectable by a user; a second sensor that enables a measurement of at least the level of ambient illumination, wherein said second sensor is integrated with an enclosure framing said at least one video display; one or more processors that execute one or more programs for controlling said first and second sensors, for utilizing said measurement of at least the level of ambient illumination in the control of rendering on said at least one video display, for storing said digital image data in a file, and for converting said digital image data in said plurality of channels into values for rendering on one or more rendering devices comprising said at least one video display; and an interface to an external computer system enabling transfer of at least said file, said file having a header enabling said external computer to process said digital image data in accordance with information accessible through said header. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)

57. A method of digital image processing comprising:
-
displaying, with the aid of a processor, menus on a color video display, said menus comprising graphical elements stored in memory and providing functions selectable by a user; capturing, responsive to user input, one or more two-dimensional images of a scene in a plurality of channels with a camera comprising a two-dimensional array of sensing elements; recording responses of a sensor that is receptive to visible illumination; calculating a measurement of at least the level of ambient illumination in the vicinity of said video display using said responses of said sensor, wherein said sensor is distinct from said two-dimensional array of sensing elements and is integrated with an enclosure framing at least said color video display; converting outputs of said sensing elements of said two-dimensional array into digital image data representative of said one or more two-dimensional images; storing said digital image data in a file, said file also having a header and fields of data providing information that enables interpretation of said digital image data by another system that receives said file through an interface; rendering, on said color video display, a representation of said two-dimensional image based upon said digital image data; and adjusting rendering upon said color video display responsive to said measurement of said at least the level of ambient illumination. - View Dependent Claims (58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71)
