000, Sharp released its first phone with lens J-SH04.
However, Sharp J-SH04's lens with only 110,000 pixels has a very average quality in photography and has not caused any trouble.
But no one expected that in the following 20 years, the mobile phone image changed drastically.
There are about three directions for inverting mobile phone images in recent years.
The first one is the heap lens number .
The reasons for early manufacturers to multi-photograph were different.
Some want to improve the quality of night scene shooting through color + black and white lens solutions; some want to assist with secondary shooting to simulate more amazing blur effect; some want to divide the work of lenses in different focal segments to meet the shooting needs from far to near.
Finally, the idea of multifocal lenses has become the mainstream solution for current imaging flagships.

The second direction is volume pixel .
For a long time, talking about mobile phone images is inseparable from pixels.
ranges from 48 million, 64 million, to 100 million pixels and 200 million pixels.
It is said that the higher the pixels, the clearer the shot is.
But simply pursuing high pixels will bring obvious "side effects" of hin. The higher the pixel of
, the smaller the area of a single pixel, the smaller the amount of light entering will also decrease, and the dark light imaging will be discounted.
is like cutting a cake. The more portions you cut, the less the amount of a single portion.
Image source network
And, high pixel shooting means that the mobile phone processor needs to process more data.
left default mode, right high pixel mode
flagship phone is fine. If it is a mid-to-low-end mobile phone with slightly weak performance, take a picture and load it for a long time.
Tsk, everyone who has experienced it knows the sourness and pleasure.
In order to solve this situation, manufacturers have developed pixel all-in-one technology.
Sony Quad Byer array
That is, during daily shooting, several adjacent pixels are used to form one, and the default output of 12 million or 16 million photos. Is this
considered a repeated jump?
is obvious, "pixel theory" is gradually not working.
So, how can you take good photos?
That has to mention the current direction of "volume" - large-size sensor .
There is a saying in the photography circle, "The bottom is bigger and the other is crushed to death."
shooting has three main elements: Beauty, Beauty, Beauty ISO (Sensitivity) , exposure time, aperture.
If a small-size sensor wants to obtain the same imaging quality as the big bottom, it requires lower ISO, longer exposure time and larger aperture.
Most people take photos with their mobile phones to take photos as they open. You ask everyone to take photos without moving them for a few seconds before they can take a photo. Who can stand it?
And the benefits of the bottom are far more than saving exposure time.
The larger sensor area means that it can have a larger amount of light input.
Get enough light information in a shorter time to achieve faster capture speed and better night scene imaging.
After all, sometimes when shooting, it is important to be "fast, accurate and ruthless".
In addition, the broadsole can also achieve better depth of field effects, which is what everyone often calls "blurry".
requires algorithm cutting simulation compared to small bottoms, and the depth of field effect achieved at the hardware level is obviously more realistic and natural.
APS-C camera depth effect
Although everyone understands the advantages of large bottom, due to the size of the body, the mobile phone sensor has always had a threshold that cannot be crossed.
That is one-inch sensor .
one inch is an introductory frame in consumer-grade cameras and is also a choice for many newbies when buying cameras.
Like the popular Sony Black Card, it is the representative of the one-inch camera.
Even if the mobile phone is supported by various image algorithms, it is difficult to fight against a one-inch camera.
1 1. In the past two years, more and more mobile phones have tried to cross the threshold and launch mobile phones equipped with one-inch main cameras.
But many manufacturers will quietly move their knife.
You should not make the focal length too wide, which will affect the shooting experience; or you should cut off the OIS optical anti-shake to reduce the weight burden of the body.
This approach is understandable, but it is not perfect enough.
can truly bring the "one-inch bottom" in mobile images to the proper level, and at present, vivo still needs to be counted.
Last month, vivo officially launched the vivo X90 series.
As the leading image flagship of the Blue Factory, the vivo X90 series has sufficient image configuration.
The most eye-catching one-inch super-large bottom main camera on vivo X90 Pro/Pro+.
Compared with the GNV main camera of the previous generation X80 Pro, the IMX989 used by vivo this time is 77% larger in terms of photosensitive area and the photosensitive ability is also improved by 43%.
As mentioned earlier, vivo X90 Pro+ can achieve a "sharp milky" depth of field blur with the advantages of the big bottom.
next door iPhone 14 Pro Although it has also been upgraded in this generation of sensor size (1/1.3 inch) .
But in front of a one-inch super large bottom, the gap is still very obvious.

In addition, in the night scene, vivo X90 Pro+ obtains more light information with the assistance of a super large bottom.
Press the shutter, "splash", and soon, the film came out.

As for models with smaller sensor size, they have to stand and wait for a long time before the film is released.
And we can clearly see that the night scene imaging using a one-inch super large bottom is purer.

In contrast, after long exposure and post-synthesis of iPhone 14 Pro Max, there are obvious sharpening marks in the film.
is like a good dish, with half a pack of MSG.

And it is obvious that vivo X90 Pro+ is also much better than iPhone 14 Pro in terms of ability to deal with complex light at night.

From a series of sample comparisons, the advantages of the broad bottom are obvious. What is the one-inch strength of
vivo?
Of course, the vivo X90 series is not the first model to eat the "one-inch super large bottom" crab.
But why is the one-inch of the vivo X90 series strong enough?
What we cannot ignore here is the killer weapon of X90 Pro/Pro+ - the maximum f/1.75 large aperture.
The advantages of large aperture are actually similar to those of the big bottom, both to increase the amount of light input and obtain better depth of field effect.
The double buff with super large bottom and large aperture allows the main camera of vivo X90 Pro/Pro+ to quickly produce films in a shorter time.
After all, if there is half a second of exposure time, it is likely that the picture will be missed.
In order to achieve the largest aperture in this industry, vivo has spent a lot of effort.
vivo X90 Pro/Pro+ The lens structure of 1G (glass) +7P (plastic) is used on the main camera module.
The glass lens is an ultra-low dispersion high-transparency glass lens.
This thing has been unveiled on the X70 series, which can effectively reduce dispersion and solve problems such as purple edge and false colors in high contrast scenarios.
In order to stuff these lenses into such a small image module, vivo adopts the solution to stack AOA lenses.
Under the AOA dynamic optical calibration process, the problem of reduction in clarity caused by lens thickness error and lens eccentricity error is accurately adjusted, effectively achieving the high-quality optical effect of X90 Pro/Pro+.
The last technology to achieve large aperture is the brand new Zeiss T* coating.
imaging quality guarantee - the new generation of Zeiss T* coated
After the light enters the lens, it will reflect. This is the cause of ghosting and glare when taking pictures.
This time, the vivo X90 series uses the new "ALC sub-wavelength bionic structure coating" on a one-inch super large bottom.
Compared with the previous generation of ALD technology, ALC technology directly lowers the reflectivity of light 42.8%.
What's more ruthless is that the X90 Pro+ has ALC coating on all 7 plastic lenses.
Next door iPhone 14 Pro Max has only one piece of ALD coating, I can only say that you can work harder.
In addition, vivo X90 Pro+ continues several excellent technologies from previous generations, including SWC ultra-low reflective coating, double low reverse AR coating, and IRCF pigment spin coating.
SWC coating is based on the principle of bionics , which can fully suppress reflected light and reduce the reflectivity to a minimum of 0.1%.
IRCF Pig coating can solve the adhesion problem of pigment and blue glass.
, a lot of coating technologies, are all to reduce the glare and ghost problems that are prone to occur when shooting on mobile phones.

All-round calculation Optical
What is mentioned above are the hardware advantages of the X90 series in imaging.
is just awesome. In today's mobile image field, powerful hardware alone is not enough to take high-quality images.
What I want to talk about below is vivo's "soft power" in the image. The imaging system of the
vivo X90 series includes four major sections: optical perception system, ultra-clear image quality engine, computing power acceleration engine, and Zhencai restore engine.
Ultra-clear image quality engine calculates multi-frame images to repair defects during shooting in an AI way.
This technology is particularly useful for telephoto shooting and can improve the resolution of the focal range above 5X.
computing power acceleration engine accelerates the computer power during shooting by integrating and accelerating the self-developed image chip and processor.
To achieve this technology, it is inseparable from the new self-developed chip V2. The chip
not only greatly improves AI capabilities, but also directly stuffs AI computing into it.
Sports capture has always been the weakness of many mobile phones.
has a one-inch big bottom that is far beyond the industry level and a self-developed chip V2. Coupled with vivo's latest high-speed capture technology, the X90 Pro+ finally adopts a 30ms ultra-low latency strategy.
Many difficult-to-capture moments can be clearly captured by X90 Pro+.
Camera
As for Zhencai Restore Engine, it is responsible for optimizing the color and tone of imaging.
For example, intelligent AWB and intelligent white plus black subtraction can improve the accuracy of white balance and the accuracy of black and white exposure through AI training.
It is not difficult to find that the vivo X90 series has indeed put a lot of effort into the image.
Whether it is optical hardware or imaging algorithms, they are currently top-level standards in the industry.
In the increasingly rolling mobile phone image field, some people pay more attention to hardware, believing that only piles of materials can produce good results;
Some people pay more attention to software, believing that as long as the algorithm is top-notch, small bottom can also be used to shoot blockbusters.
But the facts prove that only by grasping both soft and hard is the key to making a good movie. Although the "one-inch super large bottom" equipped in the
vivo X90 series is a simple word, but behind it is several years of technical accumulation.
As the super big cup, vivo X90 Pro+ is indeed strong in the image.
says it is the current flagship ceiling of the image, right?
