<p>PURPOSE:To prevent the difference of hue between an original picture informa tion and restored picture information from getting large even when an original entry number does not coincide with a restored entry number by utilizing a table in which the difference of hue between the adjacent entry numbers is small as a color look-up table(CLUT). CONSTITUTION:The entry number is inputted in an entry number changing means 1 to change the entry number. The respective entry numbers are arranged as points according to corresponding RGB values in a three-dimensional space where RGB are taken as a base, and the arrangement of the respective points whose path is the shortest of the paths which return to an origin 0 by way of all the points from the origin is obtained to change the numbers so as to ascend in this arranged order. By such constitution, the restored hue does not differ so much even when the entry numbers are a little changed in order at a succeeding image processing stage.</p> |
