Same material, shadow shield are independent platy structures, and at this moment, shadow shield can be using the material different from lens mount.
The camera lens module that the present embodiment is provided, increased the shading being arranged between lens mount and cmos sensor chip
Plate, is kept off the light of the bonding wire reflection on cmos sensor chip outside cmos sensor image area using the light-blocking member,
It is resolved the photographic flashing function problem that bonding wire causes, improves the image quality of mobile terminal.
3rd embodiment
A kind of camera lens module is present embodiments provided, the camera lens module is applied to a mobile terminal, the composition portion of the module
Divide roughly the same with the part of camera lens module described in above-mentioned first embodiment, except for the difference that, in the present embodiment
Frame of the light-blocking member in closure or circulus, based on this, the camera lens module that the present embodiment is provided mainly has the characteristics that：
In the camera lens module, whole light-blocking member is arranged at the image area of cmos sensor and the weldering of cmos sensor chip
Between line, the zone of influence of the cmos sensor is isolated with bonding wire, the light-blocking member can be with lens group to cmos sensor core
The frame-shaped or loop configuration of the closure that the extended structure in piece direction is constituted, that is, light-blocking member can be one on lens mount
Part, meanwhile, the light-blocking member can also be an independent frame-shaped or loop configuration, by the structure is fixed on lens mount
On cmos sensor chip, as long as the bonding wire played between shielding cmos sensor chip and the substrate of camera lens module is reflected
Light.
The camera lens module that the present embodiment is provided, increased the shading being arranged between lens mount and cmos sensor chip
Part, using the light-blocking member by cmos sensor chip bonding wire reflection light gear cmos sensor image area it
Outward, it is resolved the photographic flashing function problem that bonding wire causes, improves the image quality of mobile terminal.
Fourth embodiment
A kind of camera lens is present embodiments provided, the camera lens can be used in mobile terminal/intelligent mobile terminal etc. and have bat
On the terminal device of camera shooting function, the camera lens can include the described any one into 3rd embodiment of above-mentioned first embodiment
Camera lens module, therefore, the camera lens can also have various different structures, due in above-mentioned each embodiment to various mirrors
Head mould group has been described in detail, therefore no longer this is repeated herein.
As the camera lens of the present embodiment increased the light-blocking member being arranged between lens mount and cmos sensor chip,
The light that bonding wire on cmos sensor chip can be reflected by the light-blocking member is kept off outside cmos sensor image area, it is to avoid
As the reflective impact of bonding wire is taken pictures quality, improve into compared with the camera lens of existing other mobile terminals to a certain extent
As quality.
5th embodiment
The present embodiment is on the basis of the various embodiments described above, there is provided a kind of terminal, and the terminal can be Portable movable
Terminal, or intelligent terminal, optionally, the terminal can include that above-mentioned first embodiment is any described in into 3rd embodiment
A kind of camera lens module of structure, or, the terminal can also include in above-mentioned fourth embodiment it is described can have it is various not
Isostructural camera lens, as the various possible implementation of above-mentioned first embodiment to 3rd embodiment camera lens module is entered
Detailed description is gone, therefore here is omitted.
As the terminal of the present embodiment employs the above-mentioned camera lens/or camera lens module of present invention design, increased and be arranged at
Light-blocking member between lens mount and cmos sensor chip, the light-blocking member can be by the bonding wires on cmos sensor chip
The light of reflection is kept off outside cmos sensor image area, it is to avoid as bonding wire reflective impact is taken pictures quality, with it is existing its
His mobile terminal is compared.
