1. A process for capturing and decoding bar-code information in real time from a continuously displayed image video signal, comprising the steps of:
- aiming an imaging apparatus at a target of interest, said target having at least one of optically readable and bar coded information contained thereupon;
continually displaying a real time image of said target from said imaging apparatus;
selectively capturing and storing an instantaneous image of said target into the memory of a computer;
determining if bar-coded information is present in said stored image;
decoding bar-code information if bar-code readable information is contained on said instantaneous stored image while maintaining the display of said real-time image; and
outputting the decoded bar-coded information.

Abstract
A process allows an image capturing apparatus to be integrated with a personal computer to continuously display a video image of the imaging apparatus. Upon proper input by a user, or automatically after a timed interval, a snapshot of the video image is captured. An autodiscrimination process of the captured video image automatically decodes any bar-coded information present in the captured image and outputs the information.

14. A process for capturing and decoding bar-coded information in real time from a continuously displayed video signal of a target of interest, said process comprising the steps of:
-
aiming an imaging apparatus at a target of interest; continually displaying a real time image of said target obtained from said imaging apparatus; selectively capturing an instantaneous displayed image of said target and storing said image into computer memory; determining if bar-coded information is present in said captured and stored image; decoding all bar-coded information present in said captured and stored image while continually displaying said real time image of said target; and outputting the decoded bar-code information onto said real time displayed image. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. Apparatus for capturing and decoding bar-coded information from a target of interest comprising:
-
imaging means for imaging a target of interest, said target having at least one of optically readable and bar-coded information contained therein; processing means for processing an imaged target; display means for continually displaying a real-time image of said target from said imaging and processing means; image capture means for selectively capturing at least one image displayed by said display means; scanning means for scanning said at least one captured image and for determining the presence of bar-coded information in the field of view of said at least one captured image; decoding means for decoding any bar-coded information detected by said scanning means; and output means for outputting the decoded bar-coded information to said display means. - View Dependent Claims (23, 24, 25)
