Electronic device with an array of daisy chained image sensors and associated methods

摘要

An electronic device includes an array of daisy chained image sensors, with each image sensor including a pixel array. A host is coupled to an image sensor at an end of the array and is configured to insert identification codes. The identification codes include embedded data values to thereby indicate specific parts of the image data, and a set of identification codes comprising a first identification code to identify a start of a data stream and a second identification code to identify an end of the data stream.

1. A document scanner comprising:
a plurality of image sensors arranged in side-by-side relation and configured to sense an image of a document positioned adjacent thereto, each of said plurality of image sensors comprising a pixel array; said plurality of image sensors coupled together in a daisy chained arrangement and configured to operate so that a downstream image sensor appends image data to image data from an upstream image sensor; a host coupled to the daisy chain arrangement and configured to insert identification codes to indicate specific parts of the image data, wherein the identification codes comprise at least one of
a first identification code to identify a start of a data stream and a second identification code to identify an end of the data stream, andat least one further set of identification codes to identify a start and an end of the data streams associated with each image sensor.
