Image capture method and image capture and synthesis method

摘要

An image capture method includes the following steps. Firstly, an image capturing device including a line image sensor and an optical mouse sensor is provided. Then, an image capturing resolution is provided. Then, the optical mouse sensor starts counting, and the image capturing device is moved along a specified direction. Then, a sampling target value along the specified direction is acquired. Then, the line image sensor acquires at least one temporary image. Then, each temporary image is correlated with a temporary target value according to a counting result of the optical mouse sensor. Then, an absolute value of each temporary target value minus the sampling target value is calculated, and the temporary image corresponding to the minimum absolute value is determined as a to-be-synthesized image. Consequently, the overall volume of the image capturing device is reduced, and the capturing performance is optimized.
