LCOS projector having signal correction processing based on projection lens distortion

摘要

A projector is provided with: an input line memory which holds an input image signal corresponding to one line; an image processor which generates an intermediate image signal correction-processed according to distortion of a projection lens, using the input image signal transferred from the input line memory; an output line memory which holds the intermediate image signal corresponding to one line; and an LCOS which guides light radiated from a light source to the projection lens in accordance with the intermediate image signal. The image processor is provided with an input supplementation buffer which stores the input image signals of a plurality of lines, an input data buffer which stores input image signals required to generate the intermediate image signal corresponding to one line, and a number-of-supplementary-lines calculator which calculates the number of supplementary lines of the input image signals.
