Apparatus and method for encoding a picture regarding a region of interest

The apparatus according to claim to 1, configured for encoding the sample array into a data stream to be decoded by a virtual reality device.

A method for encoding a sample array which signals a spatially sampled representation of a picture, wherein the method comprises

• spectrally decomposing the sample array to obtain a decomposed representation, the decomposed representation comprising a plurality of coefficients, each of which is attributed to one of a plurality of spectral components of the decomposed representation and to one of a plurality of spatial components of the sample array,
• obtaining, from the plurality of coefficients, a subset of coefficients which are, according to the spatial components to which the coefficients are attributed, located outside of a predetermined region spatially defined within the sample array,
• attenuating the coefficients of the subset of coefficients, wherein an extent of an attenuation of a coefficient of the subset of coefficients depends on the spatial component to which the coefficient is attributed.
