Abstract: A method includes obtaining a first image, determining a first target curve of a first region occupied by the first image, where an area of the first region is equal to an area of the first image, determining a target object on the first image, moving the first image to obtain a second image, where a second target curve of a second region in which the target object on the second image is located is close to or overlaps the first target curve, and the second region is an external polygon of the target object, and cropping out an image part that is of the second image and that is moved out of the first region.

Abstract: An impedance matching circuit includes a driver circuit, a calibration circuit, a digital logic circuit, a receiving circuit and a first resistor. An output of the driver circuit is connected to the receiving circuit, and an output of the calibration circuit is connected to the first resistor. The calibration circuit is configured to cooperate with the driver circuit to perform calibration according to the impedance values of the first resistor and the receiving circuit to determine a plurality of calibration parameters obtained at different output level values. The digital logic circuit is configured to receive the plurality of calibration parameters and determine a respective target calibration parameter of each of the at least one transistor slice in the driver circuit. The driver circuit is configured to receive the target calibration parameter, and perform impedance adjustment on the at least one transistor slice according to the target calibration parameter.
