The estimation circuit has N columns and M rows of computation elements (S), each determining an error function between two values. A memory with N by M cells holds values representing the block in which movement is to be estimated. Another N by M memory holds values representing a block in a reference window. The two memories are connected to the associated computation element (S). The values of the error function for each of the columns are accumulated simultaneously in M adders (Add). A set of N by M buffers (B) are connected in series and a band of the reference window propagates itself column by column in the resulting network. The output of each buffer is connected to the input of an error function computation element (S). |
