Patent
Combining data from multiple image sensors
TL;DR: In this article, a method of combining data from multiple sensors is disclosed, which includes receiving lines of image data at an image processor having an input for a single camera, each line of the image data includes first-line data from a first image captured by a first camera and second-lines from a second image capturing by a second camera.

TL;DR: In this article, the authors describe a front-end for producing improved quality images of barcodes without requiring significant interaction with a user via a complicated user interface, using a combination of identified edges and low intensity regions within the image.
Patent
Barcode detection based on morphological operations
TL;DR: In this article, the image processor may identify regions of the image that exhibit a high concentration of edges and low optical intensity co-instantaneously as potential barcodes using a number of morphological operations.
Patent
Parallel image processing using multiple processors
TL;DR: In this article, an electronic device for parallel image processing using multiple processors is described, which includes multiple image sensors for providing image data and includes multiple processors for processing segmented image data to produce processed segmented data.
Patent
Multi-wire single-ended push-pull link with data symbol transition based clocking
TL;DR: In this paper, the authors describe a system, methods and apparatus that facilitate transmission of data over a multi-wire data communications link, particularly between two devices within an electronic apparatus.
