CONFIGURATION OF PROFILE TO COMPENSATE NONLINEARITY OF IMAGE ACQUISITION

摘要

PROBLEM TO BE SOLVED: To provide a chart and a method to use the chart enhancing a drawn digital color image. SOLUTION: The chart color patches, and each color patch includes information to attain mapping of a digitized color image from image data captured by various means in order to configure a profile that is used by revision of a tone scale and a color of the digital image. the number of the color patches is 24 or more and the number is selected to compensate the nonlinearity characteristic of image acquisition.
