Abstract
As microdisplay systems have become more affordable for various applications, the need for larger field-of-view has become important, typically for near-to-eye (NTE) applications. However, for NTE applications, pincushion distortion and color aberration are difficult to avoid, due to the high magnification of the optics for the systems. In addition to optical distortion, various distortions such as perspective distortion may occur in combination. In this paper, we propose a novel architecture and algorithm for the real-time one-shot correction of compound distortion for practical use, without using traditional radial and tangential modeling. We confirmed the performance of our proposed scheme, which is implemented on an application-specific integrated circuit by testing with full high definition liquid crystal on silicon panels.
