## Abstract

A method of operating a bar code scanning system adapted for assembling information bearing indicia (IBI) information from partial scans of IBI data which may comprise some undecodable characters, the method comprising the steps of: converting light reflected from a target into output signals representative thereof utilizing an image sensor; illuminating the target utilizing an illumination source; directing light from the target to the image sensor array utilizing receive optics; determining if information contained in IBI within the target derived from the output signals is not decodable; transmitting an image of the IBI to a host processor if the IBI is not decoded; and housing the processor, image sensor, receive optics, illumination source and display in a common housing for hand held operation.

## Claims

### Claim 1

A method of operating a bar code scanning system adapted for assembling information bearing indicia (IBI) information from partial scans of IBI data which may comprise some undecodable characters, the method comprising the steps of:
converting light reflected from a target into output signals representative thereof utilizing an image sensor;
illuminating the target utilizing an illumination source;
directing light from the target to the image sensor array utilizing receive optics;
determining if at least a portion of the information contained in the IBI within the target derived from the output signals is not decodable;
transmitting an image of the IBI and any decoded IBI information to a host device if any portion of the IBI is not decoded; and
housing a processor, the image sensor, the receive optics, the illumination source and a display in a common housing for hand held operation.

### Claim 2 (depends on 1)

A method according to claim 1, further comprising displaying the image of the IBI with the host device.

### Claim 3 (depends on 1)

A method according to claim 1, wherein the transmitting step occurs only after a predetermined number of determining step attempts.

### Claim 4 (depends on 1)

A method according to claim 1, further comprising storing the IBI image in a host device for further processing.

### Claim 5 (depends on 1)

A method according to claim 1, further comprising storing the IBI image in a host device for further processing and sending the IBI image to a third party supplier.

### Claim 6

A bar code scanning system adapted for assembling information bearing indicia (IBI) information from partial scans of IBI data which may comprise some undecodable characters, comprising:
an image sensor for converting light reflected from a target into output signals representative thereof;
an illumination source for illuminating the target;
receive optics for directing light from the target to the image sensor;
a processor for determining if any portion of the information contained in the IBI within the target derived from the output signals is not decodable, and transmitting an image of the IBI and any decoded IBI information to a host device if any portion of the IBI is not decoded; and
a housing for housing the processor, image sensor, receive optics, illumination source and a display in a common housing for hand held operation.

### Claim 7 (depends on 6)

A bar code scanning system according to claim 6, further comprising displaying the IBI image with a host device.

### Claim 8 (depends on 6)

A bar code scanning system according to claim 6, wherein the IBI image is transmitted only after a predetermined number of unsuccessful decoding attempts.

### Claim 9 (depends on 6)

A bar code scanning system according to claim 6, further comprising storing the IBI image in a host device for further processing.

### Claim 10 (depends on 6)

A bar code scanning system according to claim 6, further comprising-sending the IBI image to a third party supplier.
