Circuit for the estimation of movement in a detected picture

Abstract

Abstract In a circuit arrangement for the estimation of movement in a detected picture, video signals arising from the detection being written into at least one picture memory and then subjected to a block-by-block data-reducing encoding and in each case, for the purpose of estimating movement, in each case one block of a picture is compared with comparison blocks in a search field of a preceding picture, a first intermediate memory is provided for the block to be compared in each case and at least a second intermediate memory is provided for the corresponding search field of the preceding picture. The second intermediate memory consists of two read-write memories, in each case data from the picture memory being written into the one and data being read out from the respective other one. <IMAGE>
