Abstract: Method and arrangement for encoding a video signal, wherein a selection (39) is made between the generation of a motion-compensated encoded video signal (I, B, P) and the generation of a higher-resolution picture (IH). The creation of the higher-resolution picture (IH) relies on estimating motion in a series of subsequent pictures (f1,2,3, . . . ) of lower resolution. The higher-resolution picture (IH) is interpolated (38) from these pictures (f1,2,3, . . . ). In a preferred embodiment of the invention, previously determined regions of interest (S(ROI)) are selected (36) from the video signal. The pictures relating to these regions of interest (f1,2,3, . . . ) occupy less memory (33) than entire pictures as picked up by an image sensor (2). A conventional picture memory (33) is sufficient to store the series of pictures (f1,2,3, . . . ) that relates to a certain region of interest. Motion estimation (31) is performed on these pictures and their motion vectors (m) are stored in a vector memory (37).

Abstract: The invention provides a parallel data processing device having an array of parallel processing elements (LPA1 . . . 320) for processing a signal to obtain parallel streams of data, and means (TSMM1 . . . 80) for shuffling the parallel streams of data in a block-wise manner. The data shuffling means (TSMM1 . . . 80) have an array of addressable switch memory matrices (TSMM1 . . . 80) which are each coupled to a predetermined number of processing elements (LPA1 . . . 320). The array of switch memory matrices (TSMM1 . . . 80) solves data flow limitations of highly parallel linear array processors as well as intermediate storage requirements of image processing algorithms. In a camera system the parallel data processing device is combined with a sensor array (S).

Abstract: In a motion vector processing method, a motion vector (MV) is generated (MV-EVAL, MV-MEM) for a given picture part (I) based on a selection of a motion vector out of a predetermined set of motion vectors to obtain a selected motion vector, and the given picture part (I) is supplied (EOC) together with a selection indication (SI) of the selected motion vector. In an image signal decoder, motion data are obtained from the selection indication (SI), and an output picture part is generated based on the given picture part (I) and the motion data.
