摘要： An image extraction apparatus and flash control method for the same are provided. The method comprises taking a reference image, generates a first flash, and takes a first image. The first image is determined to be is overexposed or not. If the first image is not overexposed, a first flash parameter is set according to the first image. If so, a second flash is generated and a second image is taken. The second image is determined to be overexposed or not. If the second image is not overexposed, a second flash parameter is set according to the second image. If the second image is overexposed, a third flash parameter is set according to the reference image. Finally, a final flash is generated according to the first, second, or third flash parameter to obtain the desired image.

摘要： An autofocusing method is implemented in an image capture device comprising a lens and a sensor module. The relative positions of lens and the sensor module are adjusted for autofocusing based on a factor. First, the relative positions of the lens and the sensor module are adjusted based on a first unit of the factor to determine a plurality of states of the lens and the sensor module, where the lens renders clearer images on the sensor module. The states are utilized to estimate a best state achievable by focusing based on a second unit of the factor, where the lens renders a clearest image on the sensor module. The second unit is finer than the first unit. The lens or the sensor module is driven to the best state.

摘要： A method and a storage medium for auto exposure control are provided. A desired image is divided into a plurality of sample blocks, each includes red, green, and blue subpixels. A maximum exposure ratio and an average exposure ratio are obtained according to the maximum and average values of each red, green, and blue subpixel retrieved from each sample block and a predetermined desired maximum brightness and a predetermined desired average brightness. It is determined whether the maximum exposure ratio is smaller than the average exposure ratio. If it is, a strobe of the storage medium shines a flashlight based on the average exposure ratio, and, if it is not, the strobe shines a flashlight based on the maximum exposure ratio.
