Abstract
There is provided a method for detecting a rotation angle of a remote controller(21) in a television system(30,40) in order to realize a detection for the rotation angle of the remote controller(21) with respect to the television(20), which extends an application prospect of the television system. The television system (30,40) includes a television (20) and a remote controller (21), and the method comprises: collecting(S101), by the remote controller (21), an image of preset infrared sensors on the television (20) and imaging the collected image to a preset plane as a standard image, in a case in which the remote controller(21) does not rotate with respect to the television(20); collecting(S102), by the remote controller(21), an image of the infrared sensors on the television(20) and imaging the collected image to the preset plane again, in a case in which the remote controller(21) rotates with respect to the television(20); and calculating(S103) a rotation angle in a case in which the remote controller(21) rotates with respect to a screen of the television(20) by comparing the image with the standard image. There is further provided a television system(30,40).
