Classification: CPC G  H | IPC G  H

Claim 0:
1. A method for recognizing a motion or gesture of an object, comprising:
operating an optical sensor device to capture light reflected from the object under illumination by light emitted toward the object;
generating, by comparing the emitted light to the reflected light, a depth image including distance information indicating a distance between the optical sensor device and the object;
generating, based on the light reflected from the object, an infrared image including infrared image information associated with the object; and
determining the motion of the object based on at least one of the depth image and the infrared image wherein the depth image includes a first depth image and a second depth image, and
wherein the generating of the depth image comprises:
generating the first depth image by operating image sensor pixels that capture the light reflected from the object, according to a first operation mode; and
generating the second depth image by operating the image sensor pixels according to a second operation mode, in a case where the first depth image satisfies a first mode transition condition associated with a recognition of an identity of the object.
