Background

The full-screen technology and the full-screen mobile phone are mainstream development trends of modern smart phones at present, and the full-screen technology is a wider definition of ultra-high screen occupation than mobile phone design in the display industry. The front of an ideal full-screen mobile phone is basically completely covered by a screen, but the actual situation is difficult to achieve. The main reasons are: the front of the mobile phone generally needs to be provided with a receiver, a light sensor, a distance sensor, a front camera and other components, particularly the front camera, and along with the increase of the pixel requirement of a user, the size of the mobile phone is difficult to reduce under the prior art, so that solutions such as a bang screen, a water drop screen, a hole digging screen and a lifting camera appear, the solutions do not effectively reduce the diameter of the camera, and the solutions such as the bang screen, the water drop screen and the hole digging screen have to adopt a special-shaped display screen, which brings inconvenience to the user; the screen lifting scheme can cause the problems of difficult waterproof design, low reliability and the like of the mobile phone. In summary, how to effectively reduce the size of the front camera is a technical problem that needs to be solved by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

Fig. 2 is a comparison between the present invention and the prior art.

FIG. 3 is a comparison of CMOS structures.

In the figure: the camera comprises a 1-green lens module, a 2-red lens module, a 3-blue lens module, a 4-light sensing module, a 5-non-display area, a 6-mobile phone middle frame, a 7-camera, a 9-green pixel filter, a 10-blue pixel filter and a 11-red pixel filter.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, embodiment 1 shows a front camera suitable for a full-screen mobile phone, which includes a plurality of independent primary color filter lens modules, the plurality of primary color filter lens modules are all installed inside a non-display area 5 on a middle frame 6 of the mobile phone, and the plurality of primary color filter lens modules are horizontally disposed.

As shown in fig. 1, taking three CMOS chips as an example, 1 is a green lens module: the primary color filter is the lens module that green CMOS corresponds, 2 is red lens module: the primary color filter is a lens module corresponding to the red CMOS, and 3 is a blue lens module: the primary color filter is a lens module corresponding to a blue CMOS, each lens module comprises a focusing module and an anti-shake module, wherein the focusing module is used for ensuring the sharpness of the imaging of the lens on the CMOS, the anti-shake module is used for ensuring the stability of the imaging of the lens on the CMOS, the focusing and anti-shake modules can adjust the corresponding imaging areas according to the positions of different lenses and the distance between a shot object and the lens on the premise of having basic functions, and the imaging of the shot object on the corresponding CMOS through three groups of lenses can be kept consistent through the adjustment functions of the focusing module and the anti-shake module, so that the imaging areas of all the lenses are kept the same as much as possible; the photodiodes on each CMOS chip convert the light signals of each primary color into analog signals, and the analog signals are converted into digital signals by the analog-to-digital converter on the chip and sent to the processor. The processor firstly aligns pixels after receiving data transmitted by different CMOS, namely pixels in the same area in each CMOS sensor correspond to the imaging of the same shot object; then, according to the primary color information of each pixel, generating a picture of the real color of the shot object; 5 is the positive non-display area of cell-phone, and 6 is the cell-phone center, and can know through the contrast chart of fig. 2, the utility model discloses a mode greatly reduced of reduction leading camera size the area in cell-phone non-display area has increased the screen and has accounted for the ratio.

Fig. 3 is a CMOS structure diagram, the left side in the diagram is a schematic diagram of a conventional bayer filter with four pixels, wherein 9, 10, 11 represent green, blue, red pixel filters respectively, and it can be known from the diagram that each pixel of the conventional CMOS only samples one color information, so that other color information needs to be predicted by interpolation, which affects the imaging quality, and the utility model (shown in the right side in the diagram) will collect three primary color information of each pixel at the same time, so under the same imaging quality and pixel quantity, the CMOS size of the utility model is far smaller than that of the conventional CMOS, which can better solve the problem that the front camera occupies the space of the screen. In addition, the same CMOS only adopts the primary color filter of one color, so that the manufacturing process is simplified, and the yield of the CMOS is improved.

In embodiment 2, on the basis of embodiment 1, the non-display area 5 is further provided with a light sensing module 4, which can add a light sensing adjustment function.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
