Patent ID: 7637430

Claim:
A bar code reader comprising: an image sensor; a control circuit in communication with said image sensor and controlling said image sensor to include first and second frame exposure periods, said first and second frame exposure periods being overlapping such that said second frame exposure period commences prior to a time that said first frame exposure period terminates; at least one illumination light source for use in projecting an illumination pattern; at least one aiming light source for use in projecting an aiming pattern, wherein said control circuit in at least one operating mode coordinates control of said at least one aiming light source so that said at least one aiming light source is turned ON during said first frame exposure period while being selectively turned OFF during a portion of said first frame exposure period at which time pixels of said image sensor corresponding to said aiming pattern are being exposed, wherein said control circuit further in said at least one operating mode coordinates control of said at least one aiming light source so that said at least one aiming light source is turned ON during said second frame exposure period while being selectively turned OFF during a portion of said second frame exposure period at which time pixels of said image sensor corresponding to said aiming pattern are being exposed.
