US 2010/0248781 A1 · MOBILE TELECOMMUNICATIONS DEVICE WITH IMAGE SENSOR DIRECTED INTERNALLY AND EXTERNALLY

Abstract

The invention provides for a mobile telecommunications device that decodes tags of coded data printed on media present at points internal and external of the device. The device has an image sensor and a beam splitter for deflecting incoming light onto the image sensor. The device also includes a first infrared LED operatively directing light onto external media at the external point, with an infrared filter configured to receive light reflected from the external media onto the beam splitter. Also included is a second infrared LED operatively directing light onto media present in the internal pathway, with a mirror arrangement configured to direct light reflected from the internal media into the beam splitter.

Dependent claims

A mobile telecommunications device for sensing coded data on media placed internally or externally of the mobile telecommunications device, the device comprising:

an image sensor;
a beam splitter for deflecting light from an external point outside the device onto the image sensor, and deflecting light from an internal point within the device onto the image sensor;
a first infrared LED operatively directing light onto external media at the external point;
an infrared filter configured to receive light reflected from the external media onto the beam splitter;
a second infrared LED operatively directing light onto internal media present at the internal point;
and
a mirror arrangement configured to direct light reflected from the internal media into the beam splitter.
