Abstract: PURPOSE:To enable precise positioning by using appreciation function made by combining two indexes, i.e. correlation coefficient and difference in density of each picture element of two pictures and thereby enabling highly accurate correction of positional deviation between the two pictures. CONSTITUTION:Two pictures, a pair of positionally deviated pictures #1, #2 are divided into plural local areas P11, P12, P21...Q11, Q12, Q21... which are thought to be uniform in positional deviation through a local area dividing section, and correlation coefficient of nearby area is determined for each area. Then, rough position correction that repeats shifting in the plant of the picture to a position that makes the value maximum through a position correction object local area designating section and a rough position correcting section. Then, maximum value of variation of correlation coefficient in nearby area becomes less than previously given threshold value. At this point of time, highly accurate correction is made by repeating shifting in the direction to make the appreciation function made by combining density difference of two picture elements and correlation coefficient, and thereby precise positioning is performed.

Title: Optical data way
Inventor: INAO KIYOHARU
IPC: H04B10/29
Filed: 1984-01-30
Abstract: PURPOSE:To improve the reliability of an optical data highway by connecting a station to an optical connector having a variable coupling ratio to an optical transmission line, varying the coupling ratio of the connector with the control signal given from the station and setting the coupling ratio at 1 when the reception level is less than the fixed value at the station to perform the reproduction relaying. CONSTITUTION:An optical connector A2i having a variable coupling ratio is connected to an optical transmission line L2, and a station ST2i is connected to the connector A2i. The coupling ratio alpha of the connector A2i is controlled with a control signal Ci given from the station ST2i. Nodes ND21-26 are linked with the line L2, and the coupling ratio alpha os set at 1 in a transmission mode for transmission of signals. While the ratio alpha is set at 1 in a reception mode, and the receptiin level is set within a range 31 of receptionable signal levels at the station ST2i. When this reception level is reduced down to a rage 32 of reproduction signal levels, the ratio alpha is switched to 1 to perform the reproduction relaying. This reduces the transmission delay, the error factor and the attenuation amount between transmission and reception and therefore improves the reliability of an optical data highway.
