摘要： An image sensing module includes an image sensor and a sensing controller. The image sensor captures an image with a first frequency. The sensing controller determines whether the image sensor has detected an object according to the image. When the sensing controller determines that the image sensor has detected an object, the sensing controller switches the image sensor to capture the image with a second frequency for the image sensor to continuously detect the location of the object. By setting the first frequency higher than the second frequency, the image-sensing module detects the object in real time and the power consumption of the image-sensing module continuously detecting the location of the object is saved as well.
