Embodiment 1

[0025] Please refer to figure 1 It is an illustrative intent for the camera module of the embodiment of the present invention. Such as figure 1 As shown, the camera module has a common optical axis 100 including: the first variable focus optical lens 10 and the second inclusive optical lens 11, the first roll of focus optical lens 10 focusing and The focal length of the second variable focus optical lens 11 can be adjusted, and the first varying optical lens 10 and the second varying focus optical lens 11 are stationary on the common optical axis 100 of the camera module. The first variable focus optical lens 10 is located on one side close to the object, the second variable focus optical lens 11 located on the end image surface, and the first inclusive optical lens 10 and the second inclusible optical The photocopy of the lens 11 has passed the common optical axis 100; the first variable focus optical lens 10 and the light rays of the second variable focus optical lens 11 have fi...

Embodiment 2

[0065] The main difference between the second embodiment of the present embodiment is, in the present embodiment, the first varylax optically lens is a self-zoom transmissive, and the second variable focus optical lens is a self-zoom mirror.

[0066] Specifically, such as Figure 8 Disted, and can be combined with reference Figures 1 to 7 The camera module comprises: the first variable focus optical lens 10 and the second inclination optical lens 11, the focal length of the first inclined optimal lens 10 and the focal length of the second variable focus optical lens 11 can be adjusted. The first inclined optimistic lens 10 and the second variable focus optical lens 11 are stationary on the common optical axis 100 of the camera module, and the first variable focus optical lens 10 is located on one side of the object. The second variable focus optical lens 11 is located on the end of the final imaging surface, and the core of the first inclined optimistic lens 10 and the second varia...

Embodiment 3

[0077] The main difference of the first embodiment and the first embodiment is that in the present embodiment, the first variable focus optical lens is a self-zoom mirror, and the second variable focus optical lens is a self-zoom transmission mirror.

[0078] Specifically, such as Figure 9 Disted, and can be combined with reference Figure 1 to 8 The camera module comprises: the first variable focus optical lens 10 and the second inclination optical lens 11, the focal length of the first inclined optimal lens 10 and the focal length of the second variable focus optical lens 11 can be adjusted. The first inclined optimistic lens 10 and the second variable focus optical lens 11 are stationary on the common optical axis 100 of the camera module, and the first variable focus optical lens 10 is located on one side of the object. The second variable focus optical lens 11 is located on the end of the final imaging surface, and the core of the first inclined optimistic lens 10 and the seco...

Abstract

The invention provides a camera module and an imaging method, and the camera module comprises a first variable-focus optical lens and a second variable-focus optical lens, and the focal lengths of the first variable-focus optical lens and the second variable-focus optical lens can be adjusted. Zooming and focusing of the camera module can be realized by adjusting the focal length of the first variable-focus optical lens and the focal length of the second variable-focus optical lens. Therefore, the distance between the lenses does not need to be adjusted to realize zooming and focusing of the camera module, so that the camera module can be miniaturized.

Description

Technical field [0001] The present invention relates to the field of optical imaging, and more particularly to a camera module and an imaging method. Background technique [0002] For the traditional zoom imaging system, optical zoom is realized by changing the relative position of the associated lens in the lens group, in general, the lens group is overall, and the lens group is overall in the case where the lens group is generally shortened, and the space is required to be large. Realize the continuous change of the same lens from telephoto to wide angle. To this end, it is subject to a small space such as a terminal such as a mobile phone. The current mobile phone is mainly achieved by two tube telephoto and wide-angle shots, but the focal length cannot be changed continuously, or the "marke" structure is used. But take up a large number of mobile phone interior spaces. On the other hand, terminal modules such as traditional mobile phones are through the integral axial motion ...
