摘要： The present invention discloses a test method for image sharpness, which can instantly determine the sharpness of a captured image, wherein a captured image is firstly divided into multiple blocks with each block composed of multiple pixels; in each block of the captured image, the pixels having higher sharpnesses are selected, and the sharpnesses of those pixels are summed up to be the sharpness of the related block; the estimated sharpness of the captured image is also obtained similarly; and the estimated sharpness is compared with a threshold value to determine whether the captured image is sharp enough. Thereby, the present invention can test the sharpness of an image fast and correctly and inform the user of the status of the captured image and provide the user with corresponding suggestions.

摘要： A fast focusing method for a digital camera is applied in an auto focusing stage for judging whether the digital camera needs to be refocused. The fast focusing method includes recording a system time after a previous focusing (defined as a first time); capturing a system time before a current focusing (defined as a second time); performing a fuzziness detection procedure to acquire a focus value when a difference obtained by subtracting the first time from the second time is greater than a focusing time threshold; setting a focusing focal length range covering a reference focal length when the focus value is between a lower limit focusing threshold and an upper limit focusing threshold; capturing images at different focusing focal lengths respectively in the focusing focal length range; calculating a contrast value of each image; calculating a target focal length from the contrast values through a quadratic curve approximation method.

摘要： A continuous focusing method for a digital camera is described, which is applicable to determine whether the digital camera performs a focusing procedure or not when the digital camera switches from a first scene to a second scene in a live view stage. The continuous focusing method includes the following steps. A preview image of a second scene is obtained. A blur detection procedure is performed on the preview image, so as to acquire a corresponding focus value. It is determined whether the focus value exceeds a focusing threshold value or not; if not, a focusing procedure is performed; otherwise, if the focus value is greater than the focusing threshold value, the digital camera still maintains a current focusing focal length, which represents that a focusing focal length of the second scene is the same as that of the first scene.

摘要： An image processing method, applicable to a digital image device, includes the following steps. At least one original image of different brightness ranges is captured, and more images of different brightness ranges are generated from the original image by using an image post-processing technique.
