ABSTRACT:
A method for performing video motion estimation in video encoding, in which a video signal consists of frames comprising blocks. In the method a combined comparison value is calculated between a current video block of a frame to be encoded and at least one other video block of another frame. The current video block of the frame to be encoded comprises a set of first data values, and the at least one other video block of another frame comprises a set of second data values. Data value pairs are formed of data values from the set of first data values and equal number of corresponding data values from the set of second data values. The combined comparison value is formed by defining comparison values, each of which is defined by using data values of one data value pair of the data value pairs. Further, at least one threshold value is defined, and it is determined whether the process for defining the combined comparison value can be terminated.
