Method and apparatus for determining disparity
First Claim
1. A disparity determination method of a processing device, the method comprising:
- receiving first signals of an event from a first sensor disposed at a first location and second signals of the event from a second sensor disposed at a second location that is different than the first location;
extracting a movement direction of the event, based on at least one among the first signals and the second signals;
determining a disparity between the first sensor and the second sensor, based on the movement direction, a first difference between first times at which the event is sensed by corresponding first pixels in the first sensor, and a second difference between second times at which the event is sensed by corresponding second pixels in the first sensor and the second sensor;
generating depth information, based on the disparity; and
outputting the depth information.

Abstract
A disparity determination method and apparatus are provided. The disparity determination method includes receiving first signals of an event from a first sensor disposed at a first location and second signals of the event from a second sensor disposed at a second location that is different than the first location, and extracting a movement direction of the event, based on at least one among the first signals and the second signals. The disparity determination method further includes determining a disparity between the first sensor and the second sensor, based on the movement direction, a difference between times at which the event is sensed by corresponding pixels in the first sensor, and a difference between times at which the event is sensed by corresponding pixels in the first sensor and the second sensor.
