Gesture recognition module and gesture recognition method

A gesture recognition module, for recognizing a gesture of a user, the gesture recognition module comprising:

• a detecting unit, for capturing at least one hand image of a hand of the user, so as to sequentially acquire a first coordinate and a second coordinate;
• a computing unit coupled to the detecting unit, the computing unit for defining a first zone and a second zone according to the first coordinate and the second coordinate, respectively, and calculating a first area and a second area according to the first zone and the second zone;
• and
• a determining unit coupled to the detecting unit and the computing unit, the determining unit for recognizing the gesture according to the first coordinate, the second coordinate, the first area and the second area
• wherein after the computing unit acquires a minimum depth coordinate among a plurality of pixel areas in the first zone as a hand start depth coordinate, the computing unit adds the hand start depth coordinate and a depth for acquiring a hand end depth coordinate and accumulates a plurality of pixel areas between the hand start depth coordinate and the hand end depth coordinate for generating the first area.
