Patent number: 10739135Abstract: A distance measuring apparatus includes a light source, a light source controller, a light receiver including pixels arranged two-dimensionally, an exposure controller, and a signal processor. The light receiver outputs, to the signal processor, a signal corresponding to the amount of electric charge accumulated in the accumulator. The signal processor determines that the interference is present when at least one of (i) a ratio between signal levels of the same pixel included in the pixels, the signal levels representing respective amounts of electric charge in respective exposure periods and (ii) a ratio between signal levels of the first and second pixels exceeds a predetermined threshold with respect to a determination criterion that is based on a difference between a period in which a read gate of the first pixel is open and a period in which a read gate of the second pixel is open.Type: GrantFiled: January 12, 2018Date of Patent: August 11, 2020Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Seiji Nakamura, Keiichi Mori
