Abstract
A digital camera module is provided, which comprises a lens module, a reflecting device and an optical receiver device. Wherein, the lens module and the optical receiver device are positioned at a same side of the reflecting device. The reflecting device can reflect the beam transferred by the lens module to the optical receiver device. Compared with the existing digital camera whose components are arranged only in straight line, the whole thickness of the digital camera module can reduced and the structure layout is flexible by adopting the utility model.
Description
[technical field]
The utility model is about a kind of numerical camera mould, especially about a kind of numerical camera mould that is used for mobile phone or PDA portable electron devices such as (personal digital assistants).
[background technology]
Recently, along with developing rapidly of the significantly improving of cpu performance, image processing techniques, electronic installations such as mobile phone, PDA (personal digital assistant) or computer have all had very high digital image processing power, and the image data transmission between it is also often carried out, and is also developed rapidly as the numerical camera mould of image-pickup device thereupon.Along with the trend of mobile phone, PDA electronic installation miniaturizations day by day such as (personal digital assistants), the integral thickness of numerical camera mould also needs to obtain simultaneously improvement.
Please refer to shown in Figure 1, existing numerical camera mould mainly comprises lens module 10 (as the non-spherical lens group), optical filter 20, optical pickup apparatus 40 (CMOS or CCD) and printed circuit board (PCB) 50, wherein, lens module 10 makes the light that arrives optical pickup apparatus 40 have higher light intensity in order to converge light.But optical filter 20 filterings are incident light partly, makes imaging effect preferable.The light signal that optical pickup apparatus 40 will pass optical filter 20 converts electric signal to, and printed circuit board (PCB) 50 is handled the electric signal that optical pickup apparatus 40 produces.Should existing numerical camera mould be simple orthoscopic light path design, the focal length place that optical pickup apparatus 40 is positioned at lens module 10 just can be the optimal imaging effect, and the camera module that makes this kind orthoscopic arrange is thicker, reduces for asking thickness, certainly will design especially and increases difficulty at module.
At the problems referred to above, be necessary to provide that a kind of integral body is thin, the more resilient numerical camera mould of structure arrangement.
[utility model content]
The purpose of this utility model is to provide that a kind of integral body is thin, the more resilient numerical camera mould of structure arrangement.
In order to realize the purpose of this utility model, the utility model provides a kind of numerical camera mould, comprise lens module, reflection unit and optical pickup apparatus, wherein, lens module and optical pickup apparatus are positioned at the homonymy of reflection unit, are incident to optical pickup apparatus through the light signal that the lens module transmits after the reflection unit reflection.
Each parts of comparing existing numerical camera mould are simple orthoscopic and arrange, the homonymy that the lens module of the utility model numerical camera mould and optical pickup apparatus are positioned at reflection unit is incident to optical pickup apparatus through the light signal that the lens module transmits after the reflection unit reflection.This kind numerical camera mould changes optical path direction by a reflection unit, thereby has shortened the distance between lens module and optical pickup apparatus, and the integral thickness of numerical camera mould is reduced; In addition,, elongate whole optical path length, and need not the lens module is designed especially, thereby reduce lens module design difficulty, and structure arrangement is more flexible by the reflex of reflection unit.
[description of drawings]
Fig. 1 is the structural representation of existing numerical camera mould.
Fig. 2 is the structural representation of the utility model numerical camera mould.
[embodiment]
Please refer to shown in Figure 2, the utility model numerical camera mould comprises non-spherical lens module 1, infrared cut-off light filtering films 2, reflection unit 3, optical pickup apparatus 4 (being CMO S sensor in present embodiment) and printed circuit board (PCB) 5, and wherein non-spherical lens module 1 is made up of some non-spherical lenses.Printed circuit board (PCB) 5 is positioned at optical pickup apparatus 4 tops, be electrically connected with optical pickup apparatus 4, and this printed circuit board (PCB) 5 and optical pickup apparatus 4 are placed side by side with non-spherical lens module 1, reflection unit 3 is positioned at the below of non-spherical lens module 1 and optical pickup apparatus 4, and it will be reflexed in the optical pickup apparatus 4 by the light that non-spherical lens module 1 penetrates.
During use, after the light of object scene converges through non-spherical lens module 1, be incident to infrared cut-off light filtering films 2, infrared cut-off light filtering films 2 can stop the infrared ray in the incident light to pass through, thereby it is avoid when normal photographing producing noise, thereby more accurate when guaranteeing the image color reduction because infrared ray disturbs.The light that passes infrared cut-off light filtering films 2 is incident upon first total reflection film, 321 backs of left surface 32 of reflection unit 3 by total reflection to the second total reflection film 331, after 331 total reflections of second total reflection film, transfer to optical pickup apparatus 4 again, through behind this two total reflection film, the optical path direction of incident ray changes 180 degree.Optical pickup apparatus 4 is converted to electric signal with the light signal that receives, and promptly obtains the digital image signal of object scene after printed circuit board (PCB) 5 is handled.
Be appreciated that, the reflection unit of the utility model numerical camera mould not only is confined to Dove prism, for the light that transmits from the lens module is reflexed to the optical pickup apparatus, also can adopt a plane mirror, or the reflection unit that other can reflection ray is realized.For making the camera module obtain the optimal imaging effect, can be mutually certain angle between lens module, optical pickup apparatus and the reflection unit.
