Abstract
A reader for reading optical information is described which includes a housing for supporting a photosensitive array associated with an optical string adapted to focus optical information on the array. Also provided are array and optical string controls for controlling the array and optical string such that the output of selected images on the array may be processed via pattern recognition. Images on the array may be displayed and highlighted on a display. In this fashion a user is assisted in recognizing images of optical information incident on the array to facilitate aiming of the reader.
Claims52
An apparatus for reading two-dimensional optical information, comprising:
- (a) a housing having an opening;
- (b) a photosensitive array mounted within said housing for capturing two-dimensional optical information;
- (c) an optical system associated with said array and said housing opening of said housing for focusing said optical information on said array;
- (d) a control for controlling said array and optical system;
- (e) a memory for storing output from said array;
- (f) an electrical power supply for providing power for the operation of said apparatus;
- and
- (g) a display for displaying an image of said optical information captured by said array.
A process for reading two-dimensional optical information, comprising:
- (a) directing a reader at optical information to be read wherein said reader includes:
- 1) a housing having an opening;
- 2) a photosensitive array mounted within said housing for capturing two-dimensional optical information;
- 3) an optical system associated with said array and said opening of said housing for focusing said optical information on said array;
- 4) a control for controlling said array and optical system;
- 5) a memory for storing output from said array;
- 6) an electrical power supply for providing power for the operation of said apparatus;
- 7) a decoder for decoding optical information;
- and
- 8) a display for displaying an image of said optical information captured by said array;
- (b) displaying said image on said display;
- and
- (c) aiming said reader at an optical information set to be read at least partially with the aid of said image on said display.
An apparatus for reading optical information, comprising:
- a photosensitive system for capturing optical information without requiring the apparatus to make contact with that optical information;
- an optical system associated with said photosensitive system for focusing said optical information on said photosensitive system;
- a power supply for providing power for the operation of said apparatus;
- a display coupled with said photosensitive system for displaying an image of said optical information captured by said photosensitive system;
- and
- a portable, hand-held housing supporting said photosensitive system, said optical system, said power supply and said display.
A process for reading optical information, comprising:
- manually directing a reader at optical information to be read, wherein said reader includes:
- a photosensitive system for capturing optical information;
- an optical system associated with said photosensitive system for focusing said optical information on said photosensitive system;
- a decoder for decoding optical information;
- and a display coupled with said photosensitive system for displaying an image of said optical information captured by said photosensitive system;
- displaying an image of said optical information on said display;
- and
- aiming said reader at an optical information set to be read at least partially with the aid of said image on said display.
