Image capture device with projected display

A scanned beam image capture device, comprising:

• a visible light source;
• a beam director aligned to receive a beam of light from the visible light source and direct it in a scan pattern across a field of view;
• a detector aligned to receive light reflected from the field of view;
• a decoder containing first computer instructions for decoding a two-dimensional symbol represented by patterns of light received by the detector;
• and
• a display controller coupled to the decoder and containing second computer instructions for modulating the visible light source to produce a variable displayed pattern of light on the field of view;
• wherein the variable displayed pattern of light includes a finder pattern.
