Abstract: A method is provided for analyzing motion of a subject. The method includes receiving multiple events from an event-based sensor, the events corresponding to a luminance change of the subject; calculating velocities of the events and directions of the events; generating a motion analysis table comprising an X axis classified into multiple velocity sections, a Y axis classified into multiple direction sections, and multiple cells representing frequencies of events corresponding to combinations of the velocity sections and the direction sections; and determining a motion of the subject based on the motion analysis table.

Abstract: A time of flight (TOF) camera device and a method of driving the same are provided. The TOF camera device includes a pulse generator configured to generate a pulse signal, and generate a first photo gate signal and a second photo gate signal; a light source configured to irradiate an object with light emitted in synchronization with the pulse signal; and an image sensor configured to receive light reflected from the object in synchronization with the first photo gate signal during a first frame, and receive light reflected from the object in synchronization with the second photo gate signal during a second frame. The pulse generator is further configured to modulate the pulse signal so as to use a frequency of the light as a single frequency.

Abstract: An iris recognition device, a mobile device having the same, and a method of biometric authentication using the same are provided. The iris recognition device includes: a light source unit configured to transmit a light signal to an iris; and a light source receiver configured to receive a reflected light signal of an image of the iris from the iris, and remove an offset of the reflected light signal, corresponding to noise in the iris image, using a plurality of reference signals having different phases.
