Description

Electronic device and its photography module

The present disclosure relates to a photographic module, and more particularly to a photographic module having a plurality of lens units.

Traditional 3D photography/stereo photography is performed by using a specific distance, parallelism, and the same rotation/tilt angle (ie, the same optical axis direction) between the two lenses, and the captured image is displayed in a special display. A technique in which devices (for example, 3D glasses) are respectively conducted to the left and right eyes of a person to obtain a stereoscopic effect.

In general, when the relative distance between the two lenses increases, because the images captured by the two lenses are greatly different, the back-end system takes more time to process the image, and the ideal image is not obtained. quality. Conversely, when the relative distance between the two lenses is reduced, the more similar the images will be captured by the two lenses, the less time will be spent focusing between the different images, and the clearer images will be obtained. However, for a camera module with a dual lens, excessively reducing the spacing between the two lenses will cause the two lenses to malfunction due to magnetic interference (for example, the anti-shake function is disabled). Therefore, how to maintain the ideal spacing between the two lenses without causing design failure is one of the problems that the industry needs to solve.

In view of the above-mentioned problems of the prior art, it is an object of the present invention to provide a photographic module having at least two image capture assemblies. The image capture component operates normally at appropriate intervals and has the ability to quickly synthesize 3D images/stereoscopic images to solve the problems of conventional 3D photography/stereo photography modules.

According to some embodiments of the present disclosure, the photographic module is adapted to receive and sense light rays passing through a plurality of light introduction holes. The photography module includes a plurality of image capturing components. The image capturing components are respectively configured to receive and sense light passing through one of the light introducing holes, and respectively comprise a lens unit and a photosensitive element. The image capturing unit includes a first image capturing component and a second image capturing component, and the photosensitive element of the first image capturing component is located on a plane and the photosensitive component of the second image capturing component is located. The planes are not parallel.

Moreover, in an embodiment, the photosensitive elements of the first and second image capturing assemblies are disposed to face in opposite directions and on opposite sides of the light introducing holes.

For convenience of description, in the embodiment of FIGS. 9-11, the image capturing component 20 located on the left side of FIG. 10 is referred to as a first image capturing component, and the image capturing component 20 located on the right side of FIG. 10 is referred to as a Two image capture components. And, located at the left of Figure 10 The side light guiding component 40b is referred to as a first image capturing component, and the light guiding component 40b located on the right side of FIG. 10 is referred to as a second image capturing component.

The second side edges 412b of the first and second light guiding assemblies 40b are connected to each other. The first and second image capturing assemblies 20 are respectively adjacent to the second side 411b of the two bases 41b and disposed on the base 41b. In some embodiments, the first and second light guiding components 40b can be respectively activated, and the camera module 10c can simultaneously capture images by using the first and second image capturing components 20, and perform 2D photography or 3D photography/stereoscopic photography.

As shown in FIG. 11, in some embodiments, the optical axes O1 of the first and second image capturing assemblies 20 are co-located on the same straight line. Moreover, the plane of the photosensitive element 24 of the first image capturing component 20 is parallel to the plane of the photosensitive element 24 of the second image capturing component 20.

In some embodiments, the distance D4 between the magnetic component 271 of the first image capturing component 20 and the magnetic component 271 of the second image capturing component 20 is greater than the light corresponding to the first and second image capturing components 20 respectively. The distance D1 between the holes 511c and 512c is introduced. In this way, when the anti-vibration electromagnetic control unit 25 of the first image capturing unit 20 is normally operated, the spacing between the two light-introducing holes 511c and 512c can be further reduced, thereby improving the photography module 10c in 3D photography/ Image quality and image processing speed for stereo photography. At the same time, the photographic module 10c can selectively perform 3D photographic/stereoscopic photography using a plurality of light-introducing holes on the first surface 51c of the casing 5c, or can be performed by using a plurality of light-introducing holes on the second surface 52c of the casing 5c. 3D photography / stereo photography.

Figure 12 is a graph showing the degree of interference of the anti-vibration electromagnetic control unit of the embodiment of the present disclosure with the electromagnetic control unit of another image capturing unit at different operating positions, wherein the vertical axis shows the degree of interference of the anti-vibration electromagnetic control unit 25. The calculation method is the ratio (A/B) of the interference force (A) of the electromagnetic control unit of the other image capturing component to the anti-vibration electromagnetic control unit 25 relative to the force (B) of the anti-vibration electromagnetic control unit 25 itself. Observing this chart, it can be understood that in the case where the displacement distance of the anti-vibration electromagnetic control unit 25 is less than 120 um, the degree of interference of the anti-vibration electromagnetic control unit 25 by the magnetic elements of the other image capturing assembly is less than 5%. Therefore, the anti-vibration electromagnetic control unit 25 can operate normally within a certain degree of offset.

The photographic module of the present disclosure provides a non-magnetic material between the magnetic elements of the different image capturing components, and effectively prevents the anti-vibration electromagnetic control unit from being able to operate normally due to magnetic interference without increasing the pitch of the light-introducing holes. In this way, the exposure time of the photographic module in generating 3D photography/stereo photography can be extended to enhance the image quality of taking pictures in the dark. In addition, the light for generating 3D photography/stereoscopic imaging is incident into the photographic module through a plurality of light-introducing holes that are separated by a relatively small distance, so that the image quality and image processing of the photographic module in 3D photography/stereo photography Speed can be improved.
