Abstract: A method for adjusting the color reproduction of a color image composed of pixels provided in a plurality of color channels is based on generating a reference image from a combination of the color channels, whereby each spatial coordinate of the reference image is characterized by a reference image level. Channel averages of the color channel values of the pixels that correspond to each of at least two different valued reference image levels are generated. Specific channel averages are obtained corresponding to a near white point and a near black point from the channel averages. The specific channel averages are utilized on a pixel by pixel basis for the respective channels of the digital color image to produce a processed digital color image having improved color reproduction.

Abstract: The present invention relates to a low spatial frequency calibration arrangement for scanning systems. In the method and system of the present invention, calibration is performed to compensate for non-uniformities introduced when light scattering media is scanned. This calibration results in a non-uniformity mapping at each scanning pixel location.

Abstract: Rapid development of silver bromoiodide color negative photographic films and formation of high quality negative images suitable for scanning to produce display images of excellent quality is made possible by a novel developer solution composition and method of development. The solution is characterized by containing, in addition to the color developer compound and conventional photographic developer solution components, a water soluble pyrrolidone polymer, a high concentration of sulfite ion and a low concentration, or the absence of, bromide ion. In the novel method the developer composition contacts the exposed film at elevated temperature, e.g., 40 to 66° C., for a short development time, e.g., 20 to 90 seconds. The developed image has image quality suitable for scanning and digital manipulation to produce a digital record for forming a color display image of high quality.

The control tool includes a support element having a plurality of rows, each row having a plurality of visual density patches and representing a different process condition. At least one of the rows is used for monitoring a process condition being monitored and at least one of the other of the rows identifies an out-of-control process condition. The plurality of rows of visual density patches are designed to be correlated with a process control strip that has been processed in the photographic process to be monitored, the support element further having textual information identifying at least one process condition and describing the process condition that may need to be corrected in response to correlation of the control strip to the control tool.
