Method for identifying false alarm of optical motion sensor and optical motion sensor

The invention discloses a method for identifying false alarm of an optical motion sensor and the optical motion sensor, and the method comprises the steps: receiving pixel values of a test set of pixel units selected from a plurality of pixel units, and enabling the number of pixels of the test set to be smaller than the number of the plurality of pixel units; and performing background adjustment operation according to the pixel values of the test set. According to the invention, false motion/alarm of the sensor circuit can be sensed or detected more accurately. 本发明公开了一种识别光学运动传感器的虚假警报的方法以及光学运动传感器，该方法包括：接收从多个像素单元中选择的像素单元的一测试集的像素值，并且所述测试集的像素的数量小于所述多个像素单元的数量；以及根据所述测试集的所述像素值进行背景调整操作。本发明能够更准确地感知或检测其传感器电路的虚假运动/警报。
