A method, system and devices are provided for unidirectional transfer of data from a sender device () to a receiver device (). At the sender device, respective parts of the data are encoded to generate respective 2D barcodes, and the 2D barcodes are sequentially displayed on a display (). At the receiver device, an image sensor () is used to capture the sequentially displayed 2D barcodes to obtain a series of captured images, and in each or a subset of the series of captured images, detect a position of a respective 2D barcode in the captured image, scan the 2D barcode at the identified position to obtain barcode data, and decode the barcode data to, together with the barcode data obtained from other captured images, obtain a received version of the transmitted data.

At the sender device, respective parts of the data are encoded to generate respective 2D barcodes, and the 2D barcodes are sequentially displayed on a display (). At the receiver device, an image sensor () is used to capture the sequentially displayedD barcodes to obtain a series of captured images, and in each or a subset of the series of captured images, detect a position of a respective 2D barcode in the captured image, scan the 2D barcode at the identified position to obtain barcode data, and decode the barcode data to, together with the barcode data obtained from other captured images, obtain a received version of the transmitted data.

Provided is a display device comprising a display panel having an array of display pixel elements for producing a display output; a viewer detecting system rendering data representing 1) the illumination intensity of a body part of the viewer and 2) another property of the body part; at least one illumination source for providing illumination of a body part of the viewer; and a processor configured to 1) process the data representing the illumination intensity of a body part of the viewer and 2) drive the at least one illumination source dependent on said illumination data to adapt the illumination intensity of a body part of the viewer.

System for illuminating a viewer of a display device

The invention relates to a method for reducing moire patterns on an autostereoscopic display, which display comprises an array of pixels, each having at least one sub-pixel corresponding to a main color, lined with a view altering layer, such as a lenticular lens stack or parallax barrier, and wherein the display further comprises an eye tracking system for determining the position of the eyes of a viewer relative to the display, which method comprises the steps of: &#x2014;moire pattern detection by repeating for each main color the steps of: +activating the sub-pixels of all pixels corresponding to the single main color; obtaining moire pattern data by observing the display from a plurality of viewing positions; determining from the obtained moire pattern data the frequency, phase, direction and amplitude of the moire pattern for each of the viewing positions and storing the determined values; &#x2014;controlling the pixels of the autostereoscopic display to display images, wherein the controlling comprises at least the steps of: determining the viewing position of the eyes of a viewer using the eye tracking system; rendering 3D images from image data, while correcting the 3D images by superimposing a compensation pattern for each main color, which pattern is generated based on the stored values and the determined viewing position to reduce the moire pattern for said viewing position.
