Latest Patents

One of Nishimura's latest patents is an image recognition device. This device receives video signals representing an object to be recognized from a video camera. It converts the video signals to a two-valued input pattern and compares the input pattern with a standard pattern to recognize the object. The recognition device includes an auxiliary computing unit that carries out a predetermined auxiliary computation during a horizontal scan period of the video camera, based on the state of the input pattern. Additionally, a main computation unit performs a main computation during a vertical return scan blanking period of the video camera, utilizing the results from the auxiliary computation unit. Finally, a recognition unit identifies the input pattern concerning the standard pattern based on the main computation unit's results.

Another notable patent is a method of and apparatus for measuring the moving velocity of a linear object. This method involves illuminating the linear object with a flat laser beam that has a width larger than the amplitude of vibration. The linear object moves in the direction of its length while vibrating perpendicular to that direction. The scattered light from the linear object is received by a photoelectric conversion device through a finite-sized elliptic or slit aperture. The d.c. component of a speckle signal from the photoelectric conversion device is cut off, and the number of zero-crossings per second of the resulting signal is counted. This count value is then converted into a signal representing the longitudinal moving velocity of the linear object.
