Display element with RGB diodes adapted for overlaids by another display during optical sensing by camera, RGB diode for use in said display element and method of processing picture.

摘要

The imaging element (1) has RGB LEDs (2) regularly spaced on the outer surface, whereby stable monochromatic optical radiation sources with wavelengths above 680 nm are equally oriented between RGB LEDs (2) or next to RGB LEDs (2). The source of stable monochromatic optical radiation can be an infrared LED (3). The RGB LED display element (1) displays a static and / or dynamic image observable on the spot, the image being adapted to be overlayed by another image in its optical scanning and subsequent processing. Another image area is identified by a monochrome illuminated area that is invisible to the human eye but identified by the camera sensor. In a preferred embodiment, an RGB LED diode (2) is used which also has an infrared emitter embedded in its housing. The display element (1) is preferably used in television transmissions where the on-site advertisement is replaced by an advertisement suitable for different audiences, for example based on territorial, linguistic or interest principle.
