Abstract

Official abstract text for this publication.

A portable projector includes a projector module for projecting image data, an infrared ray output unit which outputs an infrared ray to a projected image data area, a camera unit which photographs the projected image data area, a coordinate value calculator which calculates a coordinate value corresponding to each coordinate value of the photographed projected image data area, and a controller which determines whether there is a pen or a finger input in the projected image data area according to the calculated coordinate value and performing a control for updating the image data by using an input coordinate value corresponding to the input when there is input by the one of the pen and the finger.

First claim

Opening claim text (preview).

What is claimed is: 1. A portable projector comprising: a projector module for projecting image data; an infrared ray output unit which outputs an infrared ray to a projected image data area; an infrared ray camera which receives infrared light from the projected image data area; and a controller which determines whether there is a pen input or a finger input based on a value of the infrared light of each coordinate corresponding to the projected image data area.…
