The QOMO QView Digital Processing Presenter can display images in both XGA and SXGA resolution, so there's no compression when it's attached to a high resolution display. This document camera displays 3D objects, slides, negatives and books, plus you can record via USB connection to computer for playback at a later time. The switching scaler lets you toggle back and forth between computers, DVD players or other visual presenters without fussing with wires or cables. Motorized camera head, USB connectivity and RS232 control make it a great choice.
