Patent number: 10375299Abstract: In an imaging device, a difference calculation unit calculates a differential signal between charge signals that have been accumulated and are held by first and charge holding units with different timings. A multiple sampling unit performs multiple sampling processing on the differential signal, and an analog digital conversion unit converts a signal that has undergone multiple sampling processing to a digital signal. That is, multiple sampling processing is performed on a differential signal with a higher sparsity than that of an image signal.Type: GrantFiled: September 20, 2018Date of Patent: August 6, 2019Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Satoshi Sato, Takeo Azuma, Hiroyuki Motoyama, Jun Ozawa

Publication number: 20190064829Abstract: A control device includes an electronic control unit executes steering control for avoiding a collision with an object that has a possibility of colliding with a host vehicle. The electronic control unit sets a timing when the host vehicle is predicted to pass the object as an end timing of the steering control when the steering control is performed. The electronic control unit determines whether or not a deviation possibility is present when the electronic control unit assumes that the steering control ends at the end timing. The deviation possibility is a possibility of the host vehicle deviating from a current traveling lane accompanying an end of the steering control. The electronic control unit performs reduction processing that reduces the deviation possibility when the electronic control unit determines that the deviation possibility is present.Type: ApplicationFiled: July 17, 2018Publication date: February 28, 2019Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Jun OZAWA, Minami SATO, Shinichi NAGATA, Hiroshi IZUMI
