Abstract
A light-box for illuminating a printed image includes a light source having a plurality of light-emitting sections, a plurality of contrast information, and a programmable light source controller. The plurality of contrast information is determined according to the contents of the printed image, with each piece of contrast information corresponding to one contrast generated by the plurality of light-emitting sections. Thus, the programmable light source controller drives the plurality of light-emitting sections according to the plurality of contrast information in order to generate luminance variations within different durations.
Claims16
A method for controlling the light source of a light-box wherein the light-box provides illumination for a printed image and includes a light source having a plurality of light-emitting sections and a programmable light source controller, which method comprising:
- determining a plurality of contrast information according to the contents of the printed image, with each piece of contrast information corresponding to one contrast generated by the plurality of light-emitting sections;
- and
- driving the plurality of light-emitting sections according to the plurality of contrast information by the programmable light source controller in order to generate luminance variations within different durations.
A light-box for providing illumination for a printed image, comprising:
- a light source, installed behind the printed image and including a plurality of light-emitting sections;
- a plurality of contrast information, determined according to the contents of the printed image, with each piece of contrast information corresponding to one contrast generated by the plurality of light-emitting sections;
- and
- a programmable light source controller, driving the plurality of light-emitting sections according to the plurality of contrast information in order to generate luminance variations within different durations.
