Intensity changing with reduced flicker for digitally-controlled lighting

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...

More Information
Summary: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.
