    Abstract: A mobile computing device is provided having more than one imaging engine, a nd preferably, two imagining engines. Switching circuitry is provided for switching between the two imaging engines. Each imaging engine is optimized for use in specific applications and includes different specifications from the other imaging engine. Preferably, one imaging engine is optimized to provide higher resolution images than the other imaging engine, and one imaging engine is optimized to focus an object located 7.50 to 12.50 cm from the mobile computing device (near-to-mid range imaging), while the other imaging engine is optimized to focus an object located from 12.50 cm to infinity from the mobile computing device (mid-to-far range imaging). One imaging engine preferably includes a color image sensor, while the other imaging engine includes a black and white image sensor.

    Abstract: A bioptics bar code reader has first (1) and second (2) windows disposed at an angle to each other, a first imager (3) for the first window (1) and a second imager (4) for the second window (2) and first and second optics for directing light from a bar code in a reading area between the windows to the first and second imagers. The two imagers each obtain an image of the bar code in the reading area.
