Embodiment Construction
[0033] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0034] see figure 1 As shown, it is a schematic diagram of the distribution of the image sensor array used to implement the rotation angle detection method of the present invention. In this embodiment, the image sensor array is rectangular and is composed of image sensors R(00,00)... A 31*31 rectangular sensor array R composed of R(31, 31), of course, the size of the rectangular image sensor array R can be completely determined according to specific needs. In this way, the rectangular image sensor array can be used to obtain two frames of images of the external working surface or object surface (such as the working surface of an electronic device or a finger), respectively forming a reference frame and a sampling frame, and then performing a correlation operation through the sampling frame and the reference frame, Thereby obtain the motion vector o...
