Validating the black point compensation standardization

摘要

Black point compensation is a widely used feature when using the relative colorimetric intent to transform images. This procedure was first implemented in Adobe Photoshop? in the late 1990's. This implementation is described in "Adobe Systems' Implementation of Black Point Compensation" dated 2006 and available on the Adobe website. The International Color Consortium (ICC) has recently created an updated description of this algorithm to allow black point compensation to be used in a consistent manner across applications and to provide a close match to results obtained in Photoshop with the Adobe color management module (CMM). The new document includes corrections that weren't addressed in the original Adobe paper. A number of tests have been conducted in order to check the suitability and conformance of the revised algorithm and description. In this paper, a summary of the test implementation and the checking done so far will be presented.
