Projector and method for adjusting projector

摘要

The projector includes alight source, a liquid crystal light valve that modulates first color component light based on a signal, a liquid crystal light valve that modulates second color component light from the light source based on a signal, a projection lens that projects a first image formed by the first color component light and a second image formed by the second color component light, an alignment image display control section that superimposes the first image and the second image on each other and projects the superimposed image to show position misregistration of the second image relative to the first image, an instruction input screen for shifting the second image as a whole, and an alignment adjustment section that determines correction information for correcting the position misregistration based on the shift instruction and corrects the signal based on the determined correction information.

主权项

1. A projector comprising:
a light source section that outputs light; a first light modulation section that modulates first color component light out of the light outputted from the light source section based on a first image signal; a second light modulation section that modulates second color component light out of the light outputted from the light source section based on a second image signal; a projection section that projects a first image corresponding to the light modulated by the first light modulation section and a second image corresponding to the light modulated by the second light modulation section; a display control section that superimposes the first image and the second image on each other and projects a superimposed image to show position misregistration of the second image relative to the first image; an accepting section that accepts shift instruction to shift the second image relative to the first image; and an alignment adjustment section that determines correction information for correcting the position misregistration based on the shift instruction accepted by the accepting section and corrects the second image signal based on the determined correction information, wherein the accepting section accepts the shift instruction via a first instruction input screen for shifting the second image as a whole and a second instruction input screen for shifting a predetermined portion of the second image.
