Abstract
The present disclosure generally pertains to a time-of-flight imaging circuitry configured to: obtain first image data from an image sensor, the first image data being indicative of a scene, which is illuminated with spotted light; determine a first image feature in the first image data; obtain second image data from the image sensor, the second image data being indicative of the scene; determine second image feature in the second image data; estimate a motion of the second image feature with respect to the first image feature; and merge the first and the second image data based on the estimated motion.
Claims22
Imaging circuitry configured to:
- obtain first image data from an image sensor, the first image data being indicative of a scene;
- determine a first image feature in the first image data, the first image feature having a first depth;
- obtain second image data from the image sensor, the second image data being indicative of the scene;
- determine a second image feature in the second image data;
- estimate a motion of the second image feature with respect to the first image feature;
- validate the estimated motion by comparing the first depth with a second depth of the second image feature that is determined based on the estimated motion;
- and
- merge the first and the second image data conditioned on the estimated motion being validated as accurate based on the comparison.
