Latest Patents

Lindsay's latest patents include a "Focusing and screen calibration method for display screen coupled to a video camera." This innovative method allows for the calibration of a display screen that is not visible during the process. It involves generating a reference signal to display an image, capturing that image with a video camera, and converting it into digital signals. These signals represent the brightness of pixels in a matrix, which are then analyzed to generate a graphic representation of physical parameters on a separate display screen. This process enables precise adjustments to focus, intensity, and rotation controls.

Another notable patent is the "Method and apparatus for finding objects within a visual display." This invention features a signal processing circuit that allows a computer to quickly scan memory for stored signals representing a video image. By utilizing a flag generator responsive to a lit pixel detector, the system can efficiently identify rows with lit pixels, eliminating the need for a full memory scan. This innovation significantly enhances the speed and efficiency of object detection in visual displays.
