IPC: H04N1/41
Filed: 1978-12-26
Abstract: PURPOSE: To secure the high-efficiency coding for the gradation picture by giving the run-length coding to the white part for the first line and then deciding the coordinates for the changing point picture element in the subsequent lines based on the changing point of the preceding line for combination with the gradation code to give the coding.  
     CONSTITUTION: Distance RLl 1  of the first changing point picture element on process line L 2  is counted, and then RLl 1 ' is decided to first changing point Q 1  on preceding line L 1 . Using the smaller one of those two distance RLl 1  and RLl 1 ' as the reference picture element, l 1  is decided to carry out the coding through the prescribed code table. In case l 1 ' is selected, the coding is given in the constitution of the RL code featuring a', kind b' of the relative address, density code c' and l 1 ' each. In this case, the kind of the relative address of a' is decided by 10, 11 and 1 in case Q 1  is preceding to R 1 , is next to R 1  and they are identical to each other respectively. For the selection between l 1  and l 1 ', it starts at the white in case 0 comes first, the selection of l 1  is decided in case 0 comes subsequently, the l 1 ' is decided in the case of 1 and 1 respectively.

Filed: 1989-06-26
Abstract: PURPOSE:To attain a high speed arithmetic operation and to eliminate the deterioration of the approximation accuracy by securing a constitution where a coefficient matrix decomposing circuit divides a rectangular parallelepiped into 8 similar rectangular parallelepipeds and accordingly decomposing a coefficient matrix into the upper and lower triangular matrices to invert an approximate matrix with the forward/backward substitution. CONSTITUTION:A coefficient matrix decomposing circuit 1 uses a coefficient matrix and a coefficient vector of the simultaneous linear equations obtained by a discrete approximation to a partial differential equation as the input data and decomposes a coefficient matrix into the approximate matrices which are easily inverted. At the same time, the circuit 1 decomposes the coefficient matrix into plural upper and lower triangular matrices corresponding to 8 similar partial rectangular parallelepiped lattices and approximates with the products of these triangular matrices. Then the matrices obtained by inverting the approximate matrices produced by the circuit 1 are multiplied by the vector data received from a repetitive calculation circuit 3 and outputted to this circuit 3 by a forward/backward substitution circuit 2. The circuit 2 applies the forward/backward substitution to the vector data received from the circuit 3 via the upper and lower triangular matrices to invert the approximate matrices. As a result, the high speed parallel calculations are attained with use of plural vector type arithmetic circuits and the approximation accuracy is never deteriorated.
