Latest Patents
One of his latest patents is a "Moving picture display method and apparatus." This invention involves a method for displaying moving pictures with proper tone by adjusting the combination of subfields that make up a field of the moving picture. Each subfield has a different weight of luminance, and the motion vector indicating the direction and quantity of movement is detected from image data. New image data is generated to provide a tone equivalent to what the retina would receive when the image moves, ensuring a seamless viewing experience.

It features an optical image pickup device that illuminates the surface of the board, converting optical information into a grey level image. This image is then transformed into a bi-level image, separating the wiring pattern from the background. The bi-level image undergoes size adjustments to eliminate minor conductive portions or pinholes, preventing excessive detection during inspections.
