Latest Patents

One of his latest patents is a rangefinder apparatus designed to improve the accuracy of rangefinding in low-contrast environments. In this invention, if the sensor data initially received from an A/D converter includes low-contrast data, the sensor data storage part receives the data at least one additional time. It adds the additionally received sensor data to the initially received data and stores their sum. This process allows for correlation calculations and rangefinding calculations, enabling effective rangefinding for objects with low contrast. Additionally, the time required for A/D-converting the sensor data again is significantly shorter than the integration time needed for output signals of line sensors in low luminance conditions.

Another notable patent is a distance measuring apparatus that utilizes a passive autofocus (AF) sensor. In this invention, a distance measurement object is imaged by a pair of line sensors, generating sensor data that reflects the sensor images. A CPU processes this data to generate AF data, which indicates the contrast of the sensor images. This AF data is then used to calculate correlation values, allowing for accurate distance measurements. The design simplifies the circuit and significantly reduces the processing time for generating AF data, thereby shortening the overall distance measurement time.
