Abstract: The present invention is to provide a game ball using a rubber ball, configured to comprise: a rubber ball; a cotton flannel fabric fixated and attached to the surface of the rubber ball; a first taping formed by winding an insulation tape on the surface of the fabric in the length and width directions; a foam resin material fixated and attached to the surface of the first taping; a second taping formed by winding an insulation tape on the surface of the foam resin material in the length and width directions. The present invention provides a game ball formed as the fabric, the first taping, the foam resin material, the second taping, an artificial leather are sequentially formed on the surface of the rubber ball. Therefore, the surface strength of the rubber ball is increased due to the taping, and the touch feeling of the ball is smooth due to reduced elasticity. Since the ball is lightweight and has low elasticity, a force is well transferred to the ball, and the ball can thus fly far. Thus, elderly people, children, and especially female students, who have a lack of power and techniques, are suitable to enjoy playing a game such as soccer. In addition, satisfaction for a game is high because the ball can fly far with barefoot without soccer shoes. As more passes and shoots are performed to make more goals because the ball is lightly moved, the game can be easy and fun. Moreover, the amount of exercise is increased compared to existing balls, and an injury caused by a ball during a game can be prevented.

Abstract: The present invention relates to a method for detecting a signal in a TOF camera. In an embodiment of the present invention, the TOF camera receives reflectedion light which is reflected in synchronization with a flicker timing of a light source in which pixels are flickered at high frequency in a time-sharing manner and which emit light, or receives reflectedion light which is reflected with a difference in phases different from the flicker timing, outputs multiple signals corresponding to the quantity of the received light, and measures the a distance of a subject position corresponding to the pixels on the basis thereof. The TOF camera calculates the sum of two or more signals selected from the multiple signals, compares the sum with a threshold value, and determines whether the receivedption signals of the pixels are saturated. When the sum is larger than the threshold value, it is possible to output data that distance information of the subject position corresponding to the pixels is not valid. In addition, the threshold value may be determined by the phase difference from the flicker timing when the selected two or more signals and the reflectioned light are received. Accordingly, in the TOF camera, it is possible to accurately determine whether the receivedption signals are saturated.
