摘要： An assisting focusing method is applicable in an image capture device having an auto focusing (AF) procedure. The AF procedure has a preset sampling interval. The assisting focusing method includes the following steps. An image for focusing is captured. A face parameter of a face block in the image for focusing is calculated. According to the face parameter, a parameter-to-focus conversion table is looked up to acquire a focusing section. According to the focusing section and a face sampling interval, the AF procedure is performed to acquire a target focus. The face sampling interval is smaller than the preset sampling interval.

摘要： A focus method and a photographic device using the method are disclosed. The photographic device comprises a zoom lens, an image analyzing module, a focus distance providing module and a processing module. The zoom lens is used for capturing image information of a plurality of positions; the image analyzing module is used for analyzing contrast values of the image information of the plurality of positions; the focus distance providing module is used for providing a non-equivalent and a constant focus distance interval for capturing the image information of the plurality of positions; and the processing module is electrically connected with the zoom lens, the image analyzing module, and the focus distance providing module. Whereby, the photographic device acquires the image information of the plurality of positions by the non-equivalent focus distance interval and acquires a coarse focus position, and acquires an accurate focus position by the constant focus distance according to the coarse focus position.

摘要： A fast focusing method for a digital camera is applied in the digital camera to judge whether a focusing focal length of the digital camera needs to be adjusted in an auto focusing stage. The fast focusing method includes capturing a target image at a reference focal length; performing a blur detection procedure on the target image to acquire a focus value; setting a focusing focal length range covering the reference focal length when the focus value is between a lower limit focusing threshold and an upper limit focusing threshold; capturing corresponding comparison images at different focusing focal lengths respectively in the focusing focal length range; calculating a contrast value of each comparison image; and calculating the contrast values and a target focal length through a quadratic curve approximation method, and adjusting lenses of the digital camera to the set target focal length to perform shooting.
