IPC: G06T7/40
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To eliminate an error in detection in a control system, etc., for an image position shift by performing inverse Fourier transformation by multiplying the real part of a Fourier component of correlation by a smaller positive number and making the peak of correlation due to fixed noise smaller than a peak showing a net position shift. SOLUTION: By the method for detecting the position shift between images by finding a correlation function between the two images from the product of Fourier transformation, the real part of a Fourier component of correlation is multiplied by a positive number which is smaller than 1 to perform inverse Fourier transformation, thereby making the peak of correlation due to fixed noise smaller than the peak representing the net position shift. When the images have a common detection system fixed background, only the peak of correlation by a background like that is made smaller than the peak representing the net position shift and then a control system for image position shift, etc., which uses a computer, etc., can eliminate an error in detection.

Title: Production of multilayer ceramic capacitor
Inventor: KANBE YOSHIKI
IPC: G01B17/00
Filed: 1993-06-28
Abstract: PURPOSE:To lower the fail rate when a laminate having inner electrodes is cut into raw chips by electrically detecting the inner electrode and determining the cutting position based on the detection. CONSTITUTION:The cutting position has been determined conventionally by detecting the level difference between the positions where an inner electrode 4 is present and not present at the time of press using an image sensor, for example. The conventional method has such disadvantages as the level difference can not be confirmed on the surface when the number of electrodes is low or the cutting position is shifted when the the interval of electrode is short and the central position of level difference can not be detected accurately. In the inventive method, the inner electrode of a laminate 2 is detected electrically using an eddy current type sensor 1 and thereby the cutting position can be detected accurately even if the level difference is not conspicuous on the surface of the laminate 2.
