FRONT PROJECTION TYPE VIDEO DISPLAY APPARATUS, PROJECTION IMAGE CORRECTING METHOD, AND PROJECTION IMAGE CORRECTING PROGRAM

摘要

PROBLEM TO BE SOLVED: To effectively correct blur of a projection video shown on a screen, for example, in low illumination surrounding, without increasing the size and cost of the configuration.;SOLUTION: The projector 11 includes: a liquid crystal panel that displays a projection base image shown on the screen; and a projecting optical system that projects the projection base image, displayed on the liquid crystal panel, onto the screen. An acceleration sensor 16 and a gyroscope sensor 17 detect physical vibration applied to a personal digital assistant incorporating a program 11. A CPU 10 exerts control such that a projection base image is formed around a main image, to which a frame image (i.e., a black or gray frame image in a dark environment) is added according to surroundings for the projection on the screen, and the projection base image is moved on the liquid crystal panel in a direction in which vibration is offset.;COPYRIGHT: (C)2010,JPO&INPIT
