Assessment of monitor calibration for Internet imaging

Display color can be represented by a simple two-stage model, although the display performance is affected by aging, magnetic field sand various other factors. For optimum image rendering there should be a close match between the source and destination devices, in terms of primary chromaticities, white point, gamma, palette encoding and gamut mapping. Characterization procedures for displays include visual assessment, visual matching and measurement with a tricolorimeter or telespectroradiometer. Color may be communicated in images either by encoding the image directly in a standard color space, or by attaching a profile that allows the data values to be interpreted. Color correction of Internet images may be carried out on either the receiver side or on the server side. Evaluation of the effectiveness of color Internet image delivery should include repeatability and consistency of the display characterization procedure, color accuracy of the imagery and general usability considerations.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
