IMAGE PROJECTION SYSTEM AND SEMICONDUCTOR INTEGRATED CIRCUIT
First Claim
1. An image projection system that projects an image from its lens and projects the image onto a projection plane, and if resolutions in regions of the image projected onto the projection plane are not uniform among the respective regions, corrects each of the resolutions of the image in each region based on an inverse characteristic of an optical characteristic of the lens and projects the image onto the projection plane.

Abstract
An image projection system outputs an image from a lens and projects it onto a projection plane, and if resolution of the image projected onto the projection plane in each region is not uniform among respective regions, will correct resolutions of the respective regions of the image based on an inverse characteristic of the lens optical characteristic and will project the image onto the projection plane. Moreover, when the resolution of one region of the image falls lower than the resolutions of other regions by projecting the image onto the projection plane so that a shape of the image may not be distorted, the system projects an image whose resolution is deteriorated so that the resolutions of the other regions become substantially the same as the resolution of the one region.

5. A semiconductor integrated circuit for outputting an image whose resolution is deteriorated so that resolutions of other regions may become substantially the same as a resolution of one region when the resolution of the one region of the projected image falls lower than the resolutions of other regions by projecting the image onto a projection plane so that a shape of the image may not be distorted.

6. An image projection system, comprising:
-
a projection part for projecting a target image onto a projection plane; a photographing part for photographing the projection plane onto which the target image is projected; an analysis part for analyzing a photographed image that is an image obtained by photographing the projection plane; and a correction part for correcting the target image based on an analyzed result; wherein the analysis part divides the photographed image into a plurality of regions and calculates the resolution for every region when a difference in shape between the target image and the photographed image is within a predetermined range, wherein the correction part generates a first corrected image from the target image so that the resolutions among the regions may become uniform, and wherein the projection part projects the first corrected image onto the projection plane. - View Dependent Claims (7, 8, 9, 10)
