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： An image capturing apparatus and an image correction method thereof are provided. The image capturing apparatus comprises an image capturing module, a sensing module, a storage module, and a processing module. The image capturing module captures an image. The sensing module senses an included angle between the image capturing apparatus and a horizontal plane. The storage module stores a rotation compensation data table containing a plurality of offset angles and a plurality of rotation compensation values for pixels corresponding to each offset angle. According to a difference value between the angle and a preset angle, the processing module finds out the appropriate rotation compensation values in the rotation compensation data table for rotating and correcting the image. A calibrated image is then generated, and the calibrated image matches the image captured by the image capturing device at the preset angle.
