ELECTRO-OPTIC APPARATUS AND CONTROL METHOD THEREOF

摘要

A projector includes a liquid crystal panel, an optical path shifting element which is capable of changing the optical path of light emitted from the liquid crystal panel, and an image processing unit. The optical path shifting element performs pixel shift such that light reaches different positions of a display screen in respective first to fourth unit periods acquired by dividing one frame into four parts. The image processing unit includes a conversion unit which converts a high resolution image signal into a low resolution image signal, and generates an output image signal by performing an overdrive process on the low resolution image signal according to a pixel shift state.

1. An electro-optic apparatus comprising:
an electro-optical panel in which a plurality of pixels are arranged; an optical path shifting element that is capable of changing an optical path of light which is emitted from the electro-optical panel; an optical path shifting element drive unit that drives the optical path shifting element such that, when one frame period of a high resolution image signal is divided into a plurality of unit periods which include a first unit period and a second unit period subsequent to the first unit period, and when it is assumed that a pixel shift state in which light emitted from a predetermined pixel of the electro-optical panel reaches a first position of a display screen is set to a first state and a pixel shift state in which light reaches a second position that is different from the first position of the display screen is set to a second state, the optical path shifting element enters the first state in the first unit period and enters the second state in the second unit period; and an image processing unit that converts the high resolution image signal into a low resolution image signal, and generates an output image signal which controls the plurality of pixels according to the low resolution image signal, wherein the image processing unit performs an overdrive process which compensates for response characteristics of the electro-optical panel according to the pixel shift state, and generates the output image signal.
