Abstract: Devices having a long-range imaging engine formed of two cameras having different resolution are disclosed herein. An example imaging engine includes a front-end, with the cameras, terminated in a communication interface for coupling to an external host processor that performs image processor. The front-end has a near field image sensor and a far field image sensor, and a normalization processor to receive the respective image data from the sensors and normalize that image data prior to sending to the host processor. Normalization includes adjusting an image size, aspect ratio, or pixel count complying with data rate constraints imposed by the communication interface or the host processor.

Abstract: Methods and apparatus for configuring reduced decode ranges for barcode scanners are disclosed. An example method includes determining a closest focus distance of a plurality of focus distances at which a barcode placed at a furthest limit of a reduced decode range can be successfully decoded; determining a furthest focus distance of the plurality of focus distances at which the barcode placed at a closest limit of the reduced decode range can be successfully decoded; determining a subset of the plurality of focus distances that consists of the closest focus distance, the furthest focus distance, and focus distances between the closest focus distance and the farthest focus distance; and configuring the barcode scanner to only use the subset of focus distances during subsequent attempts to decode barcodes.

Abstract: A system and method for processing an image of a document is disclosed. The method includes receiving at least one predetermined document parameter of the document. An image of the document is previewed on a display using a camera. The display provides a visual indication of a defect in the image based on the preview. A processor proposes a procedure to minimize the defect in the image. A user adjusts the camera in response to the proposal. The processor processes the image of the document.
