Abstract
A motion-detection system including a camera and a storage device is provided. The camera captures a color image and transmits the color image to a pre-processor. In a low-power mode, the pre-processor retrieves the luminance value of each pixel in the color image to generate a luminance image and performs resolution reduction on the luminance image to generate an input image. The motion-identifying device identifies a motion-object block within the input image and calculates the amount of movement of the motion-object block. When the amount of movement reaches an identification threshold, the motion-detection system enters a normal mode from the low-power mode. In the normal mode, when an object-identifying model determines that an object in the motion-object block is not a predefined object, the motion-detection system enters the low-power mode.
