On color temperatures

There is various degree of white color. One of the methods of representing degree of white color is color temperatures. White color of low color temperature is reddish white, and that of high color temperature is bluish white. In this projector, the color temperatures are set by varying each gain and bias of R (red), G (green), and B (blue) signal.

To make the color temperature higher:

Set the value of B-gain (or B-bias) larger, and the value of R-gain (or R-bias) smaller. To make the color temperature lower:

Set the value of R-gain (or R-bias) larger, and the value of B-gain (or B-bias) smaller.

One method of adjusting color temperatures is to make use of person’s skin color. Project a large still picture of human face on the screen, and adjust the color tone of the face so that it may look favorable (generally, it may look healthy).

Åú Generally, the gains are used to adjust bright pictures, and the biases are used to adjust dark pictures. Åú Using the biases is effective in adjusting color of monotone pictures. (It is especially effective for adjusting dark to intermediate portions.) For example, when the green is relatively strong, decrease the value of R-bias, or increase the values of both B-bias and R-bias evenly. Also, when the projected images are bluish, decrease the value of B-bias, and when they are reddish, decrease the value of R-bias. In this way, favorable picture quality can be obtained.
