This gesture recognition device for recognizing a gesture represented by the hand of an imaging target person, on the basis of an image obtained by imaging the imaging target person using a digital camera having an imaging zone modification mechanism for modifying an imaging zone, is provided with at least one processor, wherein, if the position of the face of the imaging target person in the image is offset from a predefined set position, the processor controls the operation of the imaging zone modification mechanism to cause the digital camera to image a proper facial position image with the position of the face at the set position, and determines whether the detected hand is the right hand or the left hand on the basis of the positional relationship between the position of the hand detected from the proper facial position image, and the set position.
