| Title: |
Intensity Changing with Reduced Flicker for Digitally-Controlled Lighting |
| Abstract: |
A system for changing a light source intensity comprises a controller, an
input interface, and a memory. The input interface is configured to
receive a command intensity for a light source, wherein the light source
has a current intensity, and wherein an intensity of the light source is
ramped toward the command intensity from the current intensity
automatically. The controller is configured to determine a non-linear
curve for the intensity of the light source, wherein at least a portion
of the non-linear curve includes a beginning slope that is steeper than
an end slope and to cause a change of a light source intensity by ramping
over a time interval, wherein the light source intensity targets
conforming to the non-linear curve for the intensity of the light source.
The memory is coupled to the processor and configured to store an
intensity value.
