Title: Vector encoding system for image data
Inventor: WATANABE HIDEYUKI
IPC: H04N19/196
Filed: 1987-01-08
Abstract: PURPOSE:To reduce the time required for vector encoding vector data by comparing a vector of a block to be processed with a vector of a block whose encoding is finished to select the succeeding processing thereby encoding the vector. CONSTITUTION:A difference between a vector Xi of a block to be processed inputted by a difference discrimination device 1 and a just preceding vector Xi-1 whose processing is finished is obtained and an index of the vector Xx-i is outputted as a code when the difference is within a prescribed threshold value. A standard data vector made in advance and an index corresponding to the vector of each standard data are stored in a data set section 6, which is connected to a matching processing circuit 5. When the matching processing circuit 5 is started by a start signal outputted from the matching start circuit 4, the standard data vector and its index are read sequentially from the data set section 6 to apply matching processing to the vector Xi inputted from a shift register R1.
