| Title: |
Intensity Changing With Reduced Flicker for Digitally-Controlled Lighting |
| Abstract: |
Changing light source intensity is disclosed. A command intensity is
received for a light source, wherein the light source has a current
intensity, and wherein a starting intensity is equal to the current
intensity when the command is received. A sequence of at least three
steps in intensity for the light source is determined, wherein each step
of the sequence is used to change the light source intensity from the
starting intensity toward the command intensity, and wherein each of the
at least three steps of the sequence are progressively smaller. A light
source intensity change is caused, wherein the sequence of the at least
three steps in intensity for the light source are added each in turn to
the current intensity with a time interval occurring between each of the
at least three steps of the sequence.
