Abstract
Official abstract text for this publication.
An electronic apparatus includes: a projection unit that projects a projection-target original image onto a projection surface; an imaging unit that captures an image of the projection surface onto which an image is projected by the projection unit; and a control unit that analyzes the photographic image of the projection surface captured by the imaging unit and adjusts a correction quantity representing an extent to which the projection-target original image is to be corrected based upon analysis results.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electronic apparatus, comprising: a projection unit that projects a test image and a projection-target original image onto a projection surface; an imaging unit that captures a photographic image of the projection surface onto which the test image is projected by the projection unit; a reflectance calculating unit that calculates a reflectance of the projection surface based upon the photographic image of the projection surface captured by the i…
