APPARATUS AND METHOD FOR PRODUCING VARIABLE INTENSITY OF LIGHT |
摘要 |
<p>A lighting control arrangement controls the user interface lighting in a portable electronic device. An output of the lighting control arrangement selectively provides lighting intensity commands to a lighting controller. Each of the lighting intensity commands indicates one of certain basic lighting intensity levels. A level selector repeatedly changes, at a frequency that is higher than an integration frequency of a human visual system, the lighting intensity command to be provided at said output.</p> |
