    摘要: An image to be interpolated is subdivided into a number of image blocks and a motion estimation technique is implemented to provide at least one initial motion vector for each of the image blocks. A modified motion vector is generated for each image block based on the initial motion vectors assigned to the individual image blocks. At least one additional image block is determined through which the motion vector assigned to the given image block passes at least partially, and the modified motion vector is generated as a function of the initial motion vector that is assigned to this at least one additional image block.

    摘要: A method for encoding first and second data words, which may represent differential data values (e.g., luminance and chrominance difference data values), onto an encoded data word includes determining a first approximation value, to which a first code word is assigned, for a first data value, and determining a second approximation value, to which a second code word is assigned, for a second data value; mapping the first and second code words onto first and second data segments, respectively, of the encoded data word; determining a first difference value between the first data value and the first approximation value and determining a second difference value between the second data value and the second approximation value; and at least partial mapping of a first difference data word representing the first difference value and/or a second difference data word representing the second difference value onto at least one additional data segment of the encoded data word. The first and second data values are represented by first and second data words, respectively, each containing a number of data bits. The first approximation value is formed in that a position is determined for the highest relevant data bit for the value of the first data word and the power of two is formed for this bit position. The second approximation value is formed in that a position is determined for the highest relevant data bit for the value of the second data word and the power of two is formed for this bit position. Each data bit position of the first data word is assigned at least one first code word that is individual to this bit position, and each data bit position of the second data word is assigned at least one second code word that is individual to this bit position. Each bit position of the first data word is assigned a first sequence number and each bit position of the second data word is assigned a second sequence number.
