8. An optical reader comprising:
-
an imaging subsystem including an image sensor and an imaging optics assembly for focusing light on said image sensor; an illumination subsystem to project light emitting diode light for use in reading decodable indicia toward a target; a hand held housing in which the imaging subsystem and the illumination subsystem are disposed; wherein the optical reader is adapted for switching between a first setting in which said light for use in decoding decodable indicia projected by said illumination subsystem is of a first color and a second setting in which said light for use in decoding decodable indicia is of a second color, the second color being different than the first color; wherein the optical reader is adapted to process data obtained utilizing the image sensor for attempting to decode decodable bar code indicia; and a manually actuated trigger, wherein said attempting to decode is responsive to an actuation of said manually actuated trigger. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
