Image stitching from multiple line scanners

A system comprising:

• a supply including a media to be scanned;
• a take-up to store the media after being scanned;
• a scanner, located between the supply and the take-up including a first line scan sensor having a first field of view and a second line scan sensor having a second field of view to scan the media while the media progresses from the supply to the take-up;
• a processor;
• and
• a memory storing instructions which, when executed by the processor, cause the processor to perform operations including:
• selecting, at a plurality of times while progressing the media from the supply to the take-up, a corresponding plurality of overlap areas on the media between a first field of view of a first line scan sensor that reads a first data stream from the media and a second field of view of a second line scan sensor that reads a second data stream;
• calculating, at each time in the plurality of times, a difference measure between the first data stream and second data stream in a current overlap area of the plurality of overlap areas for a current time of the plurality of times;
• adjusting, based on the difference measure for the current time, a size or position of the overlap area for use at a subsequent time of the plurality of times as the media progresses such that the current overlap area has a first number of pixels and a subsequent overlap area corresponding to the overlap area for the subsequent time has a second number of pixels, wherein adjusting the size of the overlap area is performed in response to one or both of the first line scan sensor and the second line scan sensor moving over time;
• and
• blending the first data stream and the second data stream at the current time at the current overlap area.
