Abstract
Method and arrangement for encoding a video signal, wherein a selection ( ) is made between the generation of a motion-compensated encoded video signal (I, B, P) and the generation of a higher-resolution picture (I ). The creation of the higher-resolution picture (I ) relies on estimating motion in a series of subsequent pictures (f . . . ) of lower resolution. The higher-resolution picture (I ) is interpolated ( ) from these pictures (f . . . ). In a preferred embodiment of the invention, previously determined regions of interest (S(ROI)) are selected ( ) from the video signal. The pictures relating to these regions of interest (f . . . ) occupy less memory ( ) than entire pictures as picked up by an image sensor ( ). A conventional picture memory ( ) is sufficient to store the series of pictures (f . . . ) that relates to a certain region of interest. Motion estimation ( ) is performed on these pictures and their motion vectors (m) are stored in a vector memory ( ). The higher-resolution pictures (I ) are interpolated ( ) from the stored pictures (f . . . ) and their motion vectors (m). The invention is applicable for sensor ( )-encoder ( ) integration, for example in a camera system ( ).
