Claim 17:
18. A motion recognition apparatus using a time of flight (ToF) sensor, comprising:
an image sensing device comprising a plurality of image sensor pixels responsive to light from an object to produce pixel output signals carrying image data representing captured images of the object and configured to generate first, second and third image data by operating the plurality of image sensor pixels according to first, second, and third operation modes, respectively;
an image processor in communication with the image sensing device and configured to generate a first depth image including first distance information indicating a distance between the image sensing device and the object, a second depth image including second distance information indicating a distance between the image sensing device and the object and an infrared image based on the first, second and third image data, respectively; and
an image analysis unit in communication with the image processor and configured to determine whether the first depth image satisfies a first mode transition condition and whether the second depth image satisfies a second mode transition condition, and determine a user input based on the infrared image.
