Patent ID: 7781990

Claim:
An illumination brightness and color control system, for adjusting the illumination brightness of each of point light sources according to a target brightness and color value, comprising: a timing sampling controller, for generating a plurality of control timings for driving each of corresponding ones of the point light sources, wherein each control timing is different; a light source driver, for generating a driving current in response to each control timing, so as to drive the corresponding point light source, so that the point light sources emit light at different times; a broadband light source monitor, for sensing and sampling the point light source that emits light at a specific time for a luminous intensity signal value in response to a sampling timing; a computing unit, for determining a corrected current value according to a difference between the target brightness and color value and the luminous intensity signal value; and a current adjuster, for adjusting the driving current generated by the light source driver according to the corrected current value.
