<p>PURPOSE:To print a picture with fidelity and tone of good quality, changing duty ratio depending on color for video signals given to a display element, then using a conventional less expensive color print paper. CONSTITUTION:A video signal illuminating fluorescent film of various colors is used as a pulse width signal with large duty ratio to a color with low sensitivity and that with small duty ratio to the color with high sensitivity corresponding to the sensitivity of color for a color sensing body. Thus, the time excited with an electron beam on the color sensing body or fluorescent film depends on each color, allowing to compensate the difference of the sensitivity by color effectively for the color sensing body.</p> |
