<p>PROBLEM TO BE SOLVED: To provide a solid focusing method and a solid focusing system.SOLUTION: A solid focusing method is provided in which a focus point of a camera module is adjusted so that the camera module is focused at a predetermined position. The method provides a cone which contains a top part. A first image is formed by roughly aligning the top part of the cone with an optical axis of the camera module, with the top part of the cone being away from the camera module, and adjusting the focus point of the camera module, related to the first image. It is included that a part of the image of the cone is clear, the camera module calculates a position of the focus point when the first image is formed, based on the first image, and the focus point of the camera module after formation of the first image is adjusted.</p> |
