摘要： A method for automatically selecting a scene mode applied in a photographic device is described. The method includes detecting an image to be captured; analyzing a principal feature of the image; comparing the principal feature with a feature standard of each scene mode according to a utilization rate ranging from high to low, so as to acquire a scene mode corresponding to the feature standard conforming to the principal feature; and adjusting current photographic parameters of the photographic device into photographic parameters corresponding to the acquired scene mode. By determining a comparison sequence according to utilization rate of each scene, the time for searching and comparing is reduced. Moreover, after each shooting, the utilization rate may be re-calculated according to the used scene mode, so as to quickly provide the scene mode required by a user.
