Abstract
The disclosed embodiments relate to a system and method for compensating for spoke light in a video unit. More specifically, there is provided a method comprising measuring a first light level during a non-spoke time of a color wheel to generate a non-spoke light level; and setting a spoke light compensation value based on the measured non-spoke light level. There is also provided a video unit comprising a light source configured to generate a first light level during a non-spoke time of a color wheel, a photodiode assembly configured to measure the first light level to generate a non-spoke light level, and a processor configured to set a spoke light compensation value based on the non-spoke light level.

A method of compensating for spoke light levels, comprising:
- measuring a spoke light level during a spoke time of a color wheel;
- measuring a non-spoke light level during a non-spoke time of the color wheel;
- iteratively adjusting a least significant bit value corresponding to the non-spoke light level to an adjusted non-spoke least significant bit value such that the non-spoke light level matches the spoke light level;
- setting a spoke light compensation value based on the adjusted non-spoke least significant bit value;
- and
- utilizing the spoke light compensation value to produce subsequent non-spoke light levels.
A video unit, comprising:
- a light source assembly configured to generate a spoke light level during a spoke time of a color wheel and to generate a non-spoke light level during a non-spoke time of the color wheel;
- a photodiode assembly configured to measure the spoke and non-spoke light levels;
- and
- a processor configured to iteratively adjust a least significant bit value corresponding to the non-spoke light level to an adjusted non-spoke least significant bit value such that the non-spoke light level matches the spoke light level, set a spoke light compensation value based on the adjusted non-spoke least significant bit value, and utilize the spoke light compensation value to produce subsequent non-spoke light levels.
A video unit, comprising:
- a means for measuring a spoke light level during a spoke time of a color wheel;
- a means for measuring a non-spoke light level during a non-spoke time of the color wheel;
- a means for iteratively adjusting a least significant bit value corresponding to the non-spoke light level to an adjusted non-spoke least significant bit value such that the non-spoke light level matches the spoke light level;
- a means for setting a spoke light compensation value based on the adjusted non-spoke least significant bit value;
- and
- a means for utilizing the spoke light compensation value to produce subsequent non-spoke light levels.
