Short-distance shooting system and close shooting module thereof

Abstract

The invention discloses a short-distance shooting system and a close shooting module thereof. The closes shooting module is arranged corresponding to an image capturing module in an electronic device to capture an object module, and is characterized by comprising a liquid state lens module and a control unit which is electrically connected with the liquid state lens unit. The control unit receives a signal from the image capturing module, and controls the focal length of the liquid state lens unit according to the signal.

Description

technical field [0001] The invention relates to an image capturing system, especially a close-up shooting system and a close-up shooting module thereof. Background technique [0002] With the advancement of technology, today's electronic devices, such as smart phones, tablet computers, etc., have more and more functions. In addition to making calls with mobile devices, users can also use them to capture images. In addition, with the development of trends, portable electronic devices are becoming thinner and lighter and easier to carry. Therefore, consumers are more and more inclined to use electronic devices to capture images. [0003] However, most common electronic devices use passive autofocus, and the electronic devices still only have a predetermined depth of field, so they are only suitable for shooting general scenes. When observing the fine structures on the surface of objects at close range, it is easy to fail due to insufficient magnification. Capture close-up im...
