Code symbol reading system
A digital-imaging based system reads graphical indicia, including code symbols, on objects such as, but not limited to, code symbol menus by the user pointing his or her finger at the particular code symbol on the code symbol menu to be read, while digital images of the code symbol menu and the pointing finger are automatically captured, buffered and processed.
1. An indicia reading system, comprising:
an imaging subsystem for capturing images of a field of view; and
an image processor configured for:
determining if an elongated object is in a captured image;
if there is not an elongated object in the captured image:
determining if an indicia is in the captured image;
if there is an indicia in the captured image, determining if more than one indicia is in the captured image; and
if there is only one indicia in the captured image, processing the captured image to read the indicia;
if there is an elongated object in the captured image:
determining if there is more than one elongated object in the captured image; and
if there is only one elongated object in the captured image, detecting a region of interest to which the elongated object is pointing and processing the captured image to read indicia within the region of interest.
2. The indicia reading system of claim 1 , wherein the image processor is configured for, if there is only one elongated object in the captured image, detecting a region of interest to which the elongated object is pointing and processing the captured image to read indicia only within the region of interest.
