Abstract: Provided is an electronic device including an event-driven vision sensor including a sensor array having a sensor that generates an event signal when detecting a change in the intensity of incident light, an IMU whose positional relation with the vision sensor is known and which measures at least one physical quantity, and an additional information generating section that generates additional information related to the event signal or an output value of the IMU by associating flow information detected on the basis of the event signal with a flow pattern associated in advance with the at least one physical quantity or an estimated value based on the at least one physical quantity.

Abstract: An image processing device includes a region identifying section that identifies a first region in which a first motion occurs in a subject in an image captured by synchronous scanning, and a second region in which a second motion different from the first motion occurs in the subject or in which the subject is not substantially moving, on the basis of an event signal generated in response to a change in intensity of light in one or a plurality of pixels of the image, and an image processing section that executes image processing different between the first region and the second region on the first region and the second region, in the image.

Abstract: Provided is an information processing device including a light source control section that changes intensity of light of a light source which irradiates eyes of a user, a reception section that receives, from an event driven vision sensor including a sensor which generates an event signal when detecting a change in intensity of a light to be incident thereon, the event signal indicating a position and a time of the change in intensity of the light reflected by the eyes of the user, and a visual line detection section that identifies the light source corresponding to the event signal on the basis of a relative positional relation among the eyes of the user, the light source, and the vision sensor, and of the event signal generated at the same time that control is carried out by the light source control section, to detect a visual line of the user.
