This applet provides a tool for performing CIECAM02
color appearance model calculations.
In the forward mode, the stimulus tristimulus
values are entered into the X, Y and Z boxes. The
adopted white point is shown in the boxes Xw, Yw and Zw.
Standard or example white points can be selected using
the pull-down menu. In addition, if the 'custom' option
is selected the Xw, Yw and Zw become editable. The Yb
or luminance factor of the background can be set using
the Yb box. The luminance of the adapting field or
LA can be set using the LA box. The surround
can be set using another pull-down menu.
Finally, the mode of either forward or inverse can be
selected using the mode pull-down menu. Selecting forward
enables the X, Y and Z text boxes while
selecting inverse enables the J, C and h text boxes. The results
of the calculation, either forward or inverse, can be seen
once the 'Convert Color' has been pressed.
Dr. Mark D. Fairchild has also put together an Excel Spreadsheet with CIECAM02 included.
Billy Bigg has also put together some nifty CIECAM02 and spatial CIECAM02 pages.
Just in time for the holidays, CIECAM02 merchandise is now avialable.
