Title:
PORTABLE ELECTRONIC DEVICE AND PROJECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/105502
Kind Code:
A1
Abstract:
The portable electronic device includes a chassis, an image projection unit provided in the chassis for projecting images, a distance detection unit which detects the distance from the image projection unit to the projection surface on which the images projected by the image projection unit are projected, and a processing unit which causes the image projection unit to project a projection image which includes at least a portion of a reference image. On the basis of the change in distance detected by the distance detection unit, the processing unit changes the ratio of the projected image to the entire reference image. By this means, an image can be magnified and displayed by a simple operation.
