Abstract: A judgment system, an electronic system, a judgment method, and a display method are provided. The judgment method includes: receiving an image by a feature acquisition module and obtaining a first key point coordinate, a second key point coordinate, and a size of a face box of a user by the feature acquisition module based on the image; and performing following steps by a judgment module: obtaining a judgment value based on an ordinate of the first key point coordinate, an ordinate of the second key point coordinate, and a size of the face box; and sending a rotation signal in response to that the judgment value satisfies a rotation condition.

Abstract: The present invention provides a detection circuit including a neural network module and a calculation circuit is disclosed. The neural network module is configured to receive an image to generate an output tensor, wherein the output tensor includes position information of a specific object and distance adjustment information. The calculation circuit is coupled to the neural network module, and is configured to calculate an initial distance between an image capture device and the specific object according to the position information of the specific object, and generate an estimated distance according to the initial distance and the distance adjustment information.
