  • Patent number: 11997402
    Abstract: Provided is a vehicular image capturing system capable of further improving characteristics such as a reduction in power consumption. The system includes: an event detection unit, installed in a vehicle, that outputs an event signal in accordance with an amount of change in an intensity of received light from a predetermined light receiving range; an image capturing unit, installed in the vehicle, that performs image capturing, the image capturing being an operation of generating and accumulating a charge in accordance with an intensity of received light from a predetermined image capturing range that at least partially overlaps with the predetermined light receiving range, and generating image information in accordance with an accumulation amount of the charge; and a control unit that outputs, to the image capturing unit, a control signal according to the event signal.

  • Patent number: 11770625
    Abstract: The present technology relates to a data processing device and a data processing method capable of suppressing power consumption. A vehicle information acquisition unit acquires vehicle information that can be acquired by a vehicle, and a control unit controls, according to the vehicle information, a frame rate of frame data generated on the basis of event data representing the occurrence of an event that occurs in an accumulation time from a start of frame generation to an end of frame generation and is a change in an electrical signal of a pixel that generates the electrical signal by performing photoelectric conversion. A data processing unit generates the frame data of the frame rate controlled by the control unit. In the present technology, the present technology can be applied to, for example, a case where frame data is generated from event data output by a dynamic vision sensor (DVS).

  • Publication number: 20220400213
    Abstract: An object recognition system of the disclosure includes: a light source emitting dot light having a predetermined pattern to an object; an event detection sensor receiving the dot light having the predetermined pattern reflected by the object and detecting the fact that a change in luminance of a pixel has exceeded a predetermined threshold as an event; and a signal processor removing information other than event information originated from the dot light emitted from the light source and having the predetermined pattern among event information detected by the event detection sensor.
