Abstract
An image capture and correction method includes steps of providing an image capture device, moving the image capture device along a specific direction to obtain an captured image and position information, performing a correction operation to the captured image, calculating to obtain a skewed angle according to the position information, setting a coordinate value of the captured image as a target value, calculating to obtain a correction value according to the target value and the skewed angle, replacing the target value with the correction value, and judging whether to continue the correction operation. Then, the correction operation is finished and the corrected captured image is stored. Therefore, the skew of the captured image is corrected, a more accurate correction value is obtained, and the advantages of precisely correcting the captured image are achieved.
