Abstract:
A method for estimating an effective luminance pattern representing a distribution of projected light in a display apparatus involves determining driving values for one or more light sources arranged to project light. The light sources are solid-state light sources such as light-emitting diodes in some embodiments. The method determines an effective luminance pattern for the projected light by determining contributions to the effective luminance pattern for different components of a point spread function and then combining the contributions of the components the effective luminance pattern to yield an estimated effective luminance pattern.
