Abstract: A stylus and a control method are provided. The stylus includes: a device body and a touch part. The touch part is arranged at at least one end of the device body. The stylus further includes a first electrode arranged at one end of the touch part far away from the device body, a second electrode and a third electrode arranged on the touch part, and a control circuit arranged on the device body. The control circuit is electrically connected to each of the first electrode, the second electrode, and the third electrode. The second electrode and the third electrode may increase the size of the electrode and ensure efficiency of data transmission between the stylus and a touch device. In addition, the included angle information is detected by using any one of the second electrode or the third electrode.

Abstract: This disclosure provides a parameter obtaining method and a terminal device, and relates to the field of communications technologies, to resolve a problem that calibration of a distance sensor is relatively complex. The method includes: obtaining a preview image of a target object in a shooting preview screen; obtaining a first measurement value of a distance sensor when a degree of coincidence between the preview image and a calibration area in the shooting preview screen exceeds a threshold; and obtaining a calibration offset corresponding to the target object based on the first measurement value and the calibration distance.
