  • Publication number: 20220256139
    Abstract: A method of operating an image sensing device includes applying control voltages to a pixel array in accordance with a test mode and performing an analog-to-digital conversion of a column line voltage to obtain one or more digital codes. The one or more digital codes are evaluated to detect an operating error associated with the column line and/or corresponding analog to digital converter. In response to an operating error, pixel values may be replaced or averaged with nearby pixel outputs not affected by the operating error.

  • Patent number: 9214083
    Abstract: Provided are an apparatus and method for controlling automatic opening of a vehicle's trunk through wireless communication between a fob key for the vehicle and a bumper LF antenna disposed in the rear of the vehicle. The apparatus controls the trunk so as to be automatically opened through communication with the bumper LF antenna on the basis of the position of the fob key and the number of receptions of an RF signal, when a fob key holder approaches the trunk for opening the trunk. Alternatively, a sensor module is attached near the trunk (particularly, a lower end center of a rear bumper) and determines whether there is the fob key, thereby allowing the trunk to be automatically opened when a sensing signal is inputted by simple movement.
