ABSTRACT:
The present invention relates to projection systems where multiple projectors are utilized to create respective complementary portions of a projected image. The present invention also relates to methods of calibrating and operating individual image projectors. According to one embodiment of the present invention, an attenuation map is generated for the projectors and pixel intensity values are established for the projectors by applying one or more intensity transfer functions to the attenuation maps. The intensity transfer functions are configured to at least partially account for the non-linear response of the output intensity of the projectors, as a function of an input intensity control signal applied to the projectors. Additional embodiments are disclosed and claimed.
