Abstract
In the present invention, RGB data outputted by a transmission side CRT monitor is converted by a profile P stored in a converter into XYZ data which is corrected in agreement with the viewing conditions on the transmitting side by having reference to detection signals from sensors S , S so that the data is outputted as L M S data. A viewing condition conversion circuit refers to detection signals from sensors S , S to correct the L M S data in agreement with the viewing conditions on the reception side to supply the resulting XYZ data to the converter . The converter refers to a profile P to convert the XYZ data into RGB data which is outputted to a CRT monitor . This equates color appearance of a picture on an input device on the transmission side to that of a picture on an output device on the reception side.
