Abstract: Embodiments of the disclosure disclose an intelligent picture frame, and a method for switching an image acquisition device in the intelligent picture frame. In this solution, there are a plurality of presentation states of the intelligent picture frame, where a plurality of image acquisition devices for finding a view in the respective presentation states are arranged on frame edges of the intelligent picture frame. An image acquisition device for finding a view is arranged separately on a frame edge of the intelligent picture frame in each presentation state, and when the intelligent picture frame in use transitions to whichever presentation state, switching can be made to the corresponding image acquisition device, so that there is a dedicated image acquisition device to find a view for the intelligent picture frame in whichever presentation state.

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).

Abstract translation: 提供了一种用于检测电视系统（30,40）中的遥控器（21）的旋转角度的方法，以便实现对于遥控器（21）相对于电视机（20）的旋转角度的检测 ），这扩展了电视系统的应用前景。 电视系统（30,40）包括电视机（20）和遥控器（21），该方法包括：通过遥控器（21）收集（S101）在电视机上的预置的红外线传感器的图像 在遥控器（21）相对于电视机（20）不旋转的情况下，将收集的图像成像为预设平面作为标准图像; 在遥控器（21）中，在遥控器（21）相对于遥控器（21）旋转的情况下，通过遥控器（21）收集（20）上的红外传感器的图像并将收集的图像再次成像到预设平面 到电视（20）; 以及通过将图像与标准图像进行比较来计算（S103）在遥控器（21）相对于电视机（20）的屏幕旋转的情况下的旋转角度。 还提供一种电视系统（30,40）。
