A motion detector responsive to the magnetic field signal and to a threshold signal is configured to generate a detector output signal having edges occurring in response to a comparison of the magnetic field signal and the threshold signal. A speed detector responsive to the detector output signal...
The position of a threshold where the extracted low-frequency component data is smaller is determined as the position of the threshold for a next gradation. The process of determining the position of the threshold is a process in a real space, and can determine the position of the threshold ...

A threshold matrix generating method includes: generating q(x, y, g) in which the number of dots in an initial dot pattern is varied; calculating an error matrix (ERR(x, y, g)) of q(x, y, g); calculating AVE(a, b) representing the uniformity of the number of dots in discrete ...
Disclosed is a threshold matrix generating device including a basic dot pattern generating unit for obtaining a basic dot pattern by carrying out a filter process by a convolution filter to an initial dot pattern in which dots are arbitrarily arranged, by obtaining a dot density of the dots ...
