MICRO-SACCADIC ACTUATION FOR AN EVENT CAMERA
First Claim
Patent Images
1. An event-based imaging device, comprising:
- an event-based sensor including a pixel array; and
an optical pathway modulator to move, via a micro-saccadic movement, one or more components of an optical pathway to shift incident light on the pixel array to cause a change in light intensity on the pixel in at least one pixel of the pixel array,wherein the optical pathway includes the event-based sensor.

Abstract
Methods, apparatus, systems and articles of manufacture are disclosed relating to micro-saccadic actuation for an event camera. An example event-based imaging device includes a sensor including a pixel array and an optical pathway modulator to move, via a micro-saccadic movement, one or more components of an optical pathway including the sensor to shift incident light on the pixel array to cause a change in light intensity on the pixel in at least one pixel of the pixel array.

15. An edge detection method, comprising:
-
moving a component of an optical pathway in a first direction via a first micro-saccadic movement to displace incident light on a dynamic vision sensor pixel array in the optical pathway; sensing a change in light intensity on the pixel, via the dynamic vision sensor pixel array, responsive to the first micro-saccadic movement of the component of the optical pathway in the first direction; and outputting the change in light intensity on the pixel in correlation with a time of occurrence of the change in light intensity on the pixel. - View Dependent Claims (16, 17, 18)

19. A non-transitory machine readable medium comprising executable instructions that, when executed, cause at least one processor to at least:
-
move a component of an optical pathway in a first direction via a first micro-saccadic movement to displace incident light on a dynamic vision sensor pixel array in the optical pathway; and sense a first change in light intensity on the pixel, via the dynamic vision sensor pixel array, responsive to the first micro-saccadic movement of the component of the optical pathway in the first direction; and output the first change in light intensity on the pixel in correlation with a time of occurrence of the first change in light intensity on the pixel. - View Dependent Claims (20)
