摘要：As smartphones rapidly improve and as their supply increases, not only high quality images but also creative and diverse functions are expected from the cameras mounted on smartphones. In this paper we propose a method of automatic photography shooting by recognizing common hand gestures used during photography shooting. From the image acquired from a smartphone camera, skin area is extracted based on the skin color data value from YCbCr color space in which characteristics of the color of the skin is well expressed. From the extracted skin area, labeling method is applied to analyze contour data, and then skin object is extracted. By using the location data of the fingers, hand area is extracted from the skin object. Then the hand gesture can be recognized by the camera which takes the photograph automatically. We were able to confirm through experiments that recognition speed was fast even under the low-end environment and that it is more effective than smartphone camera's timers.
