Latest Patents

Fujihara's latest patents include a sophisticated pattern discriminator. This device receives scanning data obtained by raster scanning objects within predefined window regions using a photoelectric converter. It converts the scanned data into pixel binary data by employing a threshold value that is dependent on the scanning position and window region. The pattern discriminator evaluates the binary data according to predetermined criteria to produce an output signal indicative of the evaluation. Additionally, a memory component stores data representing the window regions in a compressed format, indicating the coordinates of the beginning and ending points of each window region on each scanning line, along with the corresponding threshold values for each segment.

Another aspect of his pattern discriminator involves obtaining data that specifies the shapes of desired window regions approximated by polygons. This is achieved by specifying the apexes of the polygons, while a programmed CPU computes the coordinates of each pixel along the lines connecting adjacent apexes. The memory also stores the apex and coordinate data that defines the starting and ending points of each window region. Furthermore, polygonal masks within each window and sub-mask polygonal window regions can be defined similarly. A shifting detector and position corrector are also integrated to detect any positional shifts of the scanned object in relation to a previously scanned reference object, allowing for adjustments in the defined window regions.
