[0014] [First Embodiment]

[0015] First, see figure 1 As shown, figure 1 It is a block diagram of a simple module of a focusing system S according to an embodiment of the present invention. The first embodiment of the present invention provides a focusing system S, which includes an auxiliary lens module 1, a control module 2, and a main lens module 3. For example, the focusing system S provided by the present invention can be installed in an electronic device Online, such as smart phones, tablet computers, etc.

[0016] Then, like figure 1 As shown, the auxiliary lens module 1 may include an image capturing unit 11 and a liquid lens unit 12, and the image capturing unit 11 and the liquid lens unit 12 are electrically connected to each other. The control module 2 can be electrically connected to the auxiliary lens module 1 and the main lens module 3 so that the control module 2 controls the auxiliary lens module 1 and the main lens module 3. In addition, the liquid lens unit 12 ...

[0024] [Second Embodiment]

[0025] First, see figure 2 And at the same time figure 1 As shown, figure 2 It is a schematic diagram of the step flow of the focusing method according to the second embodiment of the present invention. The second embodiment of the present invention provides a focusing method to quickly perform focusing. As shown in step S100, the focal length of a liquid lens unit 12 in an auxiliary lens module 1 is adjusted to perform a focusing distance scan of the auxiliary lens module 1, wherein the auxiliary lens module 1 has a plurality of focusing sections, The liquid lens unit 12 performs focusing distance scanning on a plurality of the focusing sections. For example, the liquid lens unit 12 can be controlled by a control module 2 to adjust the focus distance from far to near or from near to far. In addition, in other embodiments, the method of adjusting the focal length of the liquid lens unit 12 may also be a single focal length modulation, a continuous...

Abstract

The invention discloses a focus system and a focus method. The focus method comprises the steps of adjusting focal distance of a liquid state lens unit in an auxiliary lens module, thereby scanning the focus distance of the auxiliary lens module, wherein the auxiliary lens module is equipped with multiple focus sections, and the liquid state lens unit carries out focus distance scanning on the multiple focus sections; analyzing the image information of the multiple focus sections, thereby obtaining the focus section with the optimum image definition; transmitting the information of the focus section with the optimum image definition to a master lens module; and carrying out automatic focus in the focus section with the optimum image definition by the master lens module according to the information of the focus section with the optimum image definition. The invention also provides a focus system.

Description

technical field [0001] The invention relates to a focusing system and a focusing method, in particular to a focusing system and a focusing method capable of fast focusing. Background technique [0002] With the advancement of technology, today's portable 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. [0003] Common portable electronic devices mostly adopt passive auto-focus and have only one lens. In addition, with the development of the trend, the image pixels of portable electronic devices are getting higher and higher. Generally speaking, the frame rate (Frame Rate) of portable electronic devices with 8 to 10 million pixels, or even 20 million pixels. About 25 ~ 30FPS or so. However, because the pixels are too high, the amount of data is too large, and the speed of data access is too slow, making it impossible to quickly capture ...
