Method and system for prediction of gamma characteristics for a display

摘要

A method and system for gamma adjustment for average power level dependency displays includes applying gamma controlled functions over a range of values at a plurality of average power levels (APLs) for a display. The gamma controlled functions include coefficients for reconstruction of the gamma controlled functions. Upon a change to an APL, interpolation is performed between the coefficients to predict a new gamma controlled function for the new APL.

1. A method comprising:
measuring gamma characteristics for a plurality of average power levels of a display to determine respective gamma controlled functions based on respective gamma curves derived from measured gamma characteristics; determining respective basis vectors and coefficients for the gamma controlled functions of the plurality of average power levels; and during operation of the display, in response to a different average power level, interpolating between coefficients associated with known average power levels to determine a respective coefficient and gamma controlled function for the different average power level.
