选择性切换画面更新率;SELECTIVE FRAME RATE SWITCHING

摘要

一种切换滑鼠的画面更新率的方法，包含：设定分别对应该滑鼠所运作的复数个画面更新率的复数个加速度临界；将该滑鼠运作于该复数个画面更新率中之一第一画面更新率；根据该滑鼠以该第一画面更新率运作时所撷取之第一画面，与该第一画面之后，以该第一画面更新率运作时所撷取之第二画面之间的差值，判断该滑鼠之速度；根据该第一画面之速度、该第二画面之速度以及该第一画面更新率，判断该第一画面以及该第二画面之间的加速度；将该加速度与该复数个加速度临界比较；直接将该滑鼠的画面更新率切换至对应于所判断之加速度临界之画面更新率。; operating the mouse at a first frame rate of the plurality of frame rates; determining a velocity of the mouse according to a difference between a first frame captured by the mouse at the first frame rate and a second frame following the first frame captured by the mouse at the first frame rate; determining an acceleration of the mouse between the first captured frame and second captured frame according to the velocity of the first frame, the velocity of the second frame, and the frame rate; comparing the acceleration with the plurality of thresholds; and directly switching the frame rate of the mouse to a frame rate which corresponds to the determined threshold.
