Description of the Invention: [Technical Field] The present invention relates to an autofocus method, and more particularly to an autofocus method suitable for a phase and adjusting the focal length by a global positioning system (GPS) And its related systems. [Prior Art] The advancement of technology and technology, including camera cameras such as conventional cameras and digital cameras, is constantly being introduced. In addition to catering to the design trend of miniaturization and diversification of the body, the optical, mechanical and electronic components of the camera have been improved to make the captured images clearer and more detailed, in order to enhance their practical functions. The designer continues to think about the subject. Although the image recording media of conventional cameras and digital cameras are completely different from the related signal processing methods, the optical construction and control are similar. Among them, the autofocus function that is obtained by adjusting the focal length of the lens to obtain a clear face is the basic function that a camera should normally have today. Here is a brief description of the autofocus method currently used in cameras. Jing refers to the first A diagram, which is a schematic diagram of the image capturing of a target 2 by the camera 1 using the autofocus method of the prior art. As shown in Fig. A, when the camera 1 is used to capture the object 2, first, the person must aim the camera 1 at the target 2. Secondly, when the camera i is photographed: • When pressed, the camera 1 emits a light R toward the target 2. When the light R is incident on the surface of the object 2, it is reflected back to the camera 1. Thereafter, the camera 1 can determine the relative distance between the camera 1 and the object 2 by analyzing the light intensity or round trip time of the light R, and then adjust the focal length of the lens to capture the image of the object 2.正 5 200819893 The heart is in real life, the choice between the athletes on the field and the march: the target of moving. When using a conventional technique to capture a moving six or two X _ focus is inaccurate and the image is unclear, the situation is quite unsatisfactory ~ X 〇 Qing tea read the first B map, which is a conventional technique using the first-A graph The camera i of the autofocus method is a schematic diagram of the appearance of the moving object 2. As shown in Fig. B, when the target 2 is in position ^, the camera 1 completes the focus procedure of the target 2. However, immediately after the image capturing process, the target 2 is displaced from position 1 to another position Ρ 2 ° because the relative distance between the camera 1 and the target 2 changes, causing the camera 1 to target the object with an incorrect focal length. 2 Image capture is performed, resulting in unclear images. When we capture valuable images that cannot be reproduced, the phenomenon of unclear images is a major deficiency of this technology. In view of the shortcomings of the prior art, the inventor of the present invention proposed that the wood wood is adjusted by the position data of the Global Positioning System (GPS) to avoid the target of the prior art. The movement, which causes the lack of focus inaccuracy. SUMMARY OF THE INVENTION One object of the present invention is to provide an autofocus method and system that calculates a camera and a target by detecting location data detected by a Global Positioning System (GPS) module of a target. The relative distance of the object is precisely the focus of the moving target. Another object of the present invention is to provide an autofocus method and system for calculating a relative distance between a camera and a specific target by receiving position data detected by a global positioning system module of a plurality of targets. Accurately target one of a plurality of moving targets to a specific target of 200819893. Entering a target;; 7Γ/pair; ^ ‘the face is used for a camera. First, the step of receiving the target of the '=^7 focus method is the latitude and longitude of the first object in the global positioning system.

Further, the steps of the invention are moved. The latitude and longitude of the object in the full axis, ° then 'depending on the specific entanglement: then, according to the phase; the distance group = Ming ==:, the lens mode step of adjusting the camera. The invention of the lens of the i-cam camera is aimed at the specific object. The invention further discloses an automatic focusing process for the target object. The automatic pair = for - camera tracking module and an arithmetic / control module; = include - target object tracking module set 200819893 standard: to detect the location of the target information, and wireless fortunate Do not show the location of the target of δ hai. The camera includes a one-touch device. The system is set in the device receiving module. The target position receives the Μ== group wireless connection for receiving the target object and the target object. The relative distance is further determined by :: ::,:: The camera extracts the image of the target at the focal length.

The system is suitable for the camera target tracking module and the one, the 糸, 糸, and the 模组 获 module are respectively set in the material pull group. The target object is tracked to output the position data of the # target in the current tH/subline mode. ί2 and the target tracking module are wirelessly located in the position of the target. The control module is cautious, and is divided. Determining the position of a specific target, the relative distance of the specific target according to the location of the specific target, and then extracting and synchronizing the image of the specific target with the focal length. To make the camera positionable The position of the system, the position of the m standard includes the overview of the target in the global = and the detailed description of the following steps to explain the other purposes and advantages of the invention taken in order to achieve the intended purpose 200819893 will be in the follow-up Description [Embodiment] / Hundred, please read the second A picture, which is a schematic view of the first embodiment of the automatic pairing system of the present invention.
