    Abstract: A method for assist in focal length detection is adapted to a digital camera having a flash. The method includes the following steps. First, the flash of the digital camera is actuated and an image having a face portion is captured. Afterwards, an exposure feature value of the face portion in the image is calculated. A focus range comparison table is looked up according to the exposure feature value to obtain an initial focus position. Then, a focus procedure is performed according to the initial focus position to obtain a target focal length. After the target focal length is obtained, a flash feature value of the image is further calculated, and a guide number (GN) and a diaphragm value are set according to the flash feature value.
