Abstract

A bar code reading terminal can, in one embodiment, include a two-dimensional image sensor and an imaging assembly. The terminal can be configured, in response to receipt of a trigger signal, to buffer a set of frames and subject each frame of the set of frames to a decode attempt. The terminal can also be configured to convert the convert the captured set of video frames into a compressed video format, and transfer the resulting video file to a file server or to one or more playback devices, in response to a user interface action, or in response to difficult read condition having been detected. The terminal can also be configured to establish two-way video- and audio-communication with a remote video- and audio-streaming device. The video capturing and streaming operation of the terminal can be controlled remotely from a playback device via web interface.

First claim

The invention claimed is:

1. An imaging terminal comprising:
an image sensor;
a lens assembly for focusing an image onto the image sensor;
at least one wireless communication interface;
a memory;
instructions stored in the memory which upon execution are operative for:
capturing video frames using the image sensor;
attempting to decode frames of the captured video frames for decodable indicia;
transforming one or more of the captured video frames into a compressed video file format;
transmitting at least a portion of the compressed video file to an external computing device; and
receiving inputs from the external computing device via the wireless communication interface, wherein the received inputs are to remotely control the imaging terminal and the received inputs correspond to at least one of, a control command to switch on or switch off the capturing of the video and one of more values of parameters controlling the capturing of the video frames and the transforming of the captured video frames into the compressed video file format, wherein the parameters include at least one of brightness, saturation, and hue.

2. The imaging terminal of claim 1 , wherein the instructions stored in the memory which upon execution are operative for marking one or more captured video frames related to a failed attempt to read a decodable indicia.

3. The imaging terminal of claim 2 , wherein the instructions stored in the memory which upon execution are operative for displaying the marked one or more captured video frames to an operator.

4. The imaging terminal of claim 1 , wherein the instructions stored in the memory which upon execution are operative for, in response to a successful attempt to decode frames of the captured video frames for decodable indicia, transfer the decoded indicia data to another server system.

5. The imaging terminal of claim 1 , wherein the instructions stored in the memory which upon execution are operative for, in response to a successful attempt to decode frames of the captured video frames for decodable indicia, store the decoded indicia data in the memory.

6. The imaging terminal of claim 1 , wherein the instructions stored in the memory which upon execution are operative for, in response to a successful attempt to decode frames of the captured video frames for decodable indicia, display the decoded indicia data on a display of the imaging terminal.

7. The imaging terminal of claim 1 , wherein the instructions stored in the memory which upon execution are operative for, in response to a successful attempt to decode frames of the captured video frames for decodable indicia:
transfer the decoded indicia data to another server system;
store the decoded indicia data in the memory; and/or
display the decoded indicia data on a display of the imaging terminal.

8. An imaging terminal comprising:
an image sensor;
a lens assembly focusing an image onto the image sensor;
at least one wireless communication interface;
a memory;
instructions stored in the memory which upon execution are operative for:
capturing video frames using the image sensor;
attempting to decode frames of the captured video frames for decodable indicia;
transforming one or more of the captured video frames into a compressed video file format; and
transmitting via the wireless communication interface at least a portion of the compressed video file to one or more peer terminal devices; and

a graphical user interface (GUI) to provide a list of active peer terminals and a link quality indicative of signal strength associated with each of the active peer terminals;
wherein an operator of the imaging terminal for transmitting the portion of compressed video file selects one or more active peer terminals from the list based on the link quality associated with each of the active peer terminals.

9. The imaging terminal of claim 8 , wherein the instructions stored in the memory which upon execution are operative for marking one or more captured video frames related to a failed attempt to read a decodable indicia.

10. The imaging terminal of claim 9 , wherein the instructions stored in the memory which upon execution are operative for displaying the marked one or more captured video frames to an operator.

11. The imaging terminal of claim 8 , wherein the instructions stored in the memory which upon execution are operative for, in response to a successful attempt to decode frames of the captured video frames for decodable indicia, transfer the decoded indicia data to another server system.

12. The imaging terminal of claim 8 , wherein the instructions stored in the memory which upon execution are operative for, in response to a successful attempt to decode frames of the captured video frames for decodable indicia, store the decoded indicia data in the memory.

13. The imaging terminal of claim 8 , wherein the instructions stored in the memory which upon execution are operative for, in response to a successful attempt to decode frames of the captured video frames for decodable indicia, display the decoded indicia data on the graphical user interface.

14. The imaging terminal of claim 8 , wherein the instructions stored in the memory which upon execution are operative for, in response to a successful attempt to decode frames of the captured video frames for decodable indicia:
transfer the decoded indicia data to another server system;
store the decoded indicia data in the memory; and/or
display the decoded indicia data on the graphical user interface.

15. An imaging terminal comprising:
an image sensor;
a lens assembly focusing an image onto the image sensor;
at least one wireless communication interface;
a memory;
instructions stored in the memory which upon execution are operative for:
capturing video frames using the image sensor;
attempting to decode frames of said the captured video frames for decodable indicia; and
transforming one or more of the captured video frames into a compressed video file format; and

a graphical user interface (GUI) for uploading the compressed video file to a server, wherein the GUI provides an interface for receiving inputs related to at least one of a server name, an internet protocol (IP) address associated with a server, a file name, and a file description for the compressed video file, wherein the compressed video file is to be processed for determining a defect associated with the imaging terminal and wherein the processing includes determining if the imaging terminal was in motion while capturing the frames and an association of a saturation condition with the captured frames.

16. The imaging terminal of claim 15 , wherein the instructions stored in the memory which upon execution are operative for marking one or more captured video frames related to a failed attempt to read a decodable indicia.

17. The imaging terminal of claim 16 , wherein the instructions stored in the memory which upon execution are operative for displaying the marked one or more captured video frames to an operator.

18. The imaging terminal of claim 15 , wherein the instructions stored in the memory which upon execution are operative for, in response to a successful attempt to decode frames of the captured video frames for decodable indicia, transfer the decoded indicia data to another server system.

19. The imaging terminal of claim 15 , wherein the instructions stored in the memory which upon execution are operative for, in response to a successful attempt to decode frames of the captured video frames for decodable
