Latest Patents

One of his latest patents is a camera with a visual line position detection device and method. This innovative camera is designed to shorten the time required for auto-focus detection while allowing for more accurate selection of the focus detection point. It includes a focus detection device that outputs results from multiple distance measurements, enabling the camera to detect focus for one of these points. Additionally, a liquid crystal display device shows specified symbols overlapping the subject image at the corresponding positions of each point. A microprocessor processes the distance measurements and selects the focus detection point based on the photographer's visual line position, excluding points with an infinite focus distance.

Another notable patent is a camera with shake detection and display. This camera features a shake amount detection system that identifies the amount of camera shake. It also includes a drive system that adjusts the correction lens to counteract shake and a movement amount detection system that monitors the lens's movement. The lens MPU determines if the shake has been negated and outputs a warning signal if it has not. The camera MPU then activates a warning display system to alert the user.
