Sony patents system using event cameras to track attention points
Sony describes a device that combines a standard sensor with an event-based camera to identify where a user is looking or focusing. The event camera only sends data when light changes at a pixel, allowing the system to pinpoint specific 'attention points' in real-time with less data than traditional video.
In the filing’s own words
Provided is an information processing device including a detection section that detects an attention point in a detection target on the basis of an output of a first sensor and an event signal generated with temporal correlation with time for specifying the output of the first sensor among event signals generated by a second sensor including an event-based sensor for asynchronously generating event signals when detecting a change in the intensity of light incident on each pixel.
What exactly they claim (claim 1)
1. An information processing device comprising: at least one memory having computer program code stored therein; and at least one processor coupled to the memory, that upon execution of the program code, configured to: detect an attention point in a detection target on a basis of an output signal of a first sensor and one or more event signals, wherein the one or more event signals are generated in temporal correlation with the output signal of the first sensor, wherein the one or more event signals are among a plurality of event signals generated by a second sensor, and wherein the second sensor comprising an event-based sensor that is configured to asynchronously generate event signals upon detecting a change in intensity of incident light for each pixel.
