            Analysis of anti human design mobile phone camera protruding why

            In fact, mobile phone camera manufacturers do not want to take a prominent design, they are forced to do so.
            Since the popularity of mobile phone photography, which means that, in order to meet market demand, the camera factory must make the camera thin to do.
            The main part that determines the imaging effect of mobile phone camera is not only lens, sensor, but also DSP. DSP is also called the digital signal processing chip, network camera brain effect is equivalent to the computer CPU, its main function is through a series of complex mathematical algorithms, to optimize the processing of digital image signal from the CMOS sensor, and the processed signal to the display, is the core network equipment camera.

            High pixel camera because of the size of DSP upgrade process, as has been done in the 14 years, from 16M (16 million pixels) camera motor, to this year's 16M AF (16 million AF) motor and 16M FF camera module can be seen in two years time, the mold has been "reduced".

            But when it comes to thinning, because of the limitations of optical structures, the higher the pixels, the more lenses, the thicker the module. Currently on the market most of the mobile phone 5P or 6P lens, such as millet 3 using a 5P lens (4 layers of plastic lenses +1 blue glass lenses), and some mobile phone uses 6P camera more advanced (5 layer plastic lens +1 blue glass lenses), theoretically, 6P lens imaging is more real.

            It can be said that in order to pursue better imaging effect and thinner body thickness, the camera protruding is inevitable. We can say that the camera bulge is the product of compromise between performance and appearance

            The history of focal length changes of iPhone (picture from quote)


            As you can see from the figure above, the actual focal length and the focal length of iPhone are getting smaller and smaller. In order to broaden the field of view, this means that Apple will evolve from the original standard lens to a convex wide-angle lens.
            This can not help but raise a question, why HUAWEI P10 can do the camera does not protrude it?
            The answer is: because of innovation.
            1. innovative camera architecture solutions
            In the previous product, camera module is plastic support wall is fixed on the front of the shell, the supporting wall thickness in 0.4mm, from the beginning of the HUAWEI P8 series, manufacturers will consider using the supporting wall will affect the whole thickness. Two schemes of industry generally use the local mobile phone to keep slim, keep the camera camera protruding; or flat, and the thickness of the whole sacrifice.
            But HUAWEI P8 did not compromise, in order to reduce the 0.4mm, P8 in the camera architecture program made bold innovation.
            (1) remove the plastic support wall of the front shell, and put the camera module directly on the Cover Lens.
            (2) in order to ensure the strength of the front shell, the thickness of the side ribs around the camera is emphasized.
            (3) in order to further reduce the lateral impact of the camera, a two color injection shock absorber is used to protect the camera.
            2. ultra thin camera module scheme
            HUAWEI uses high cost high strength ceramic as substrate to realize Cavity process. The process is to dig the groove on the ceramic substrate, so that the contact point of the chip is sinking, so as to reduce the chip height of the CMOS chip about 0.15mm, which is the common substrate can not do.
            At the same time, HUAWEI adopted the module design scheme of lens convex body, lower body height of OIS motor, save the space available to the layout structure to make the internal structure more compact, the slimmer.
