Abstract: A coding method for data compression of a power spectra of an optoelectronic component and a decoding method are disclosed. In an embodiment, a coding method includes providing a power spectrum, sampling the power spectrum at particular sampling wavelengths in order to provide a discrete source spectrum, indexing the discrete source spectrum in order to provide a source graph having discrete source values, producing an image graph having discrete image values by transforming the source graph from a source range into an image range with a discrete frequency transform, performing compression of the image graph, and digitizing the compressed image graph in order to produce compressed spectral data.

Abstract: An optoelectronic lighting device that illuminates a scene to be captured as an image includes a pixelated emitter including a plurality of light emitting pixels that illuminate a scene to be captured as an image, and a driving device configured to individually drive the pixels depending on at least one parameter to illuminate the scene to be recorded with a predetermined illuminance distribution.
