ENCODER FOR ENCODING, AND DECODER FOR DECODING, A 2-DIMENSIONAL DIGITAL IMAGE REPRESENTATION INTO A DATA STREAM USING APPLYING ADDITIONAL INFORMATION TO A DIFFERENT COEFFICIENT

An encoder for at least partially encoding a digital image representation into a data stream is shown. The encoder may comprise a processor for encoding groups of coefficients representing spatial components of the digital image representation. Furthermore, the processor may form the data stream usi...

Zusammenfassung:An encoder for at least partially encoding a digital image representation into a data stream is shown. The encoder may comprise a processor for encoding groups of coefficients representing spatial components of the digital image representation. Furthermore, the processor may form the data stream using the encoded groups of coefficients wherein, if a coefficient is zero, the processor is configured to omit a respective sign information from encoding and to apply, for each omitted reference sign, additional information to a different coefficient.
