Abstract
A Contact Image Sensor (CIS) module in combination with a Field-Programmer Gate Array (FPGA) of an image device cooperate to identify, track, and record media document images for media documents being tracked within a valuable media depository/dispenser.
Claims20
A method, comprising:
- determining, by a Field-Programmable Gate Array (FPGA), to initiate storage of scanlines of pixels received from an image sensor as portions of a document image for a document;
- and
- providing, by the FPGA, the scanlines from an onboard FPGA memory to an integrated microcontroller upon a request by the microcontroller.
A method, comprising:
- (i) detecting a startup condition for an image device integrated along a transport path of a valuable media depository/dispenser;
- (ii) taking a baseline value for pixels averaged in a scanline returned from a Contact Image Sensor (CIS) module for an image of a back of a track for the transport path;
- (iii) receiving, by an image circuit board, a start document detection command provided by a microcontroller of the image circuit board;
- (iv) determining, by the image circuit board, that a document is present on the track based on scanlines received from the CIS module and comparing an averaged value of least one of those scanlines against the baseline value;
- (v) recording, by the image circuit board, the scanlines and additional scanlines in onboard image circuit board memory as document scanlines representing a document image for the document;
- and
- (vi) transferring, by the image circuit board, the document scanlines from the onboard image circuit board memory when polled by the microcontroller.
4 more elements
An imaging device, comprising:
- at least one Contact Image Sensor (CIS) module;
- a microcontroller;
- and
- a Field-Programmable Gate Array (FPGA) interfaced to the at least one CIS module and the microcontroller;
- wherein the FPGA is configured to:
- i) initiate document detection upon a first instruction from the microcontroller, ii) detect a start of a document image for a document based on first scanlines of pixel values provided by the CIS module independent of any instruction from the microcontroller, iii) record the first scanlines and second scanlines provided by the CIS module as document scanlines for the document image in an onboard FPGA memory, and iv) provide the document scanlines from the onboard FPGA memory upon a request from the microcontroller.
