A method of and an apparatus for generating a normalizing curve. |
摘要 |
<p>A normalizing curve (Crx) is generated by correcting a reference normalizing curve. The character of the normalized curve depends on dummy shadow and highlight points (A4, A3) as well as shadow and highlight points (A2, A1), which are determined as a function of the statistical distribution of densities on an original image. Color original image signals representative of the original image are converted through the normalizing curve to obtain converted color image signals in which a gray balance in the intermediate density region is corrected. <IMAGE></p> |
