Abstract: A method and an apparatus of constructing a chess playing model are disclosed, method includes: acquiring a video image of each chess player; determining a two-dimensional position information for a first expression characterization point in the video image and a marking information for a facial structure characterization point in the first expression characterization point; determining a rotation information for each chess player in a specified direction; reconstructing a three-dimensional reference face model of each chess player so as to generate a three-dimensional target face model of the chess player; reconstructing a three-dimensional target chess player model of the chess player; reconstructing a three-dimensional target chess game model; and reconstructing a three-dimensional target chess playing model.

Abstract: A controller includes an input/output circuit and a reference voltage generating circuit. The input/output circuit includes a plurality of receiving circuits. Each receiving circuit receives and processes one data bit and generates an output bit accordingly. The reference voltage generating circuit is coupled to the input/output circuit and includes a plurality of circuit units for providing a plurality of reference voltages. One of the circuit units is coupled to one of the receiving circuits to provide a reference voltage to the corresponding receiving circuit and the receiving circuit processes the data bit according to the received reference voltage.

Abstract: A data reception chip coupled to an external memory including a first input-output pin configured to output first data and including a comparison module and a voltage generation module is provided. The comparison module is coupled to the first input-output pin to receive the first data and to compare the first data with a first reference voltage to identify the value of the first data. The voltage generation module is configured to generate the first reference voltage. The voltage generation module includes a first resistor and a second resistor. The second resistor is connected to the first resistor in series. The first and second resistors divide a first operation voltage to generate the first reference voltage.
