The image capturing device includes a zoom lens and captures an image frame with a focus length. The memory unit previously saves a lookup table of depths versus sharpness associated with at least one the focus length of the zoom lens. The processing unit is configured to calculate a current sharpness value of at least one object image in the image frame and to obtain a current depth of the object image according to the lookup table."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gesture recognition system and gesture recognition method based on sharpness values","description":"A gesture recognition system includes an image capturing device, a memory unit and a processing unit.
