摘要： Switching is performed between a global shutter method and a local shutter method. A pixel control unit 30 performs local shutter and global shutter on a pixel. The image generation unit 40 generates a first frame, which is an image based on the first image signal, and a second frame, which is an image based on the second image signal. The self-position estimation unit 50 generates a surrounding map from the first frame. The object detection unit 60 detects a target object from the second frame and generates target object information.

摘要： Provided is a sensing system that includes a light emitting section, a predetermined number of pixels, a solid-state imaging element, and a counting section. In the solid-state imaging element, the light emitting section emits irradiation light in synchronization with a light emission control signal having a higher frequency than a vertical synchronization signal. Each of the predetermined number of pixels generates a pulse signal by photoelectric conversion and the counting section counts a number of pulse signals in synchronization with each of the light emission control signal and the vertical synchronization signal.
