There has always been debate about whether CCD or CMOS is better. After all, CCD will be eliminated. But why does Leica camera S2P still use CCD?

Domestic online information is basically all about the advantages of CCD, and even one shortcoming can be found. This is too weird

Speaking of CMOS, everyone knows Sony and Howe , Samsung and other manufacturers

But don’t forget that Sony and Panasonic were originally CCD manufacturers

If CCD beats CMOS, then why did Sony switch to the CMOS camp? With Sony's "character" of not sparing any cost, if CCD is better than CMOS in all aspects, Sony will definitely focus on CCD

CCDセンサーと Compare the advantages of CMOS CMOS

CMOS CMOS performance CMOS CCD CMOS CMOS special featuresみを発向しています. Today's CMOS センサーは, and outside れたフレームレートの高さ, excellent れた picture quality, sensitivity の高 さを実appears できるようになっているのです.

CMOS technology and CCD technology are better than べて, さまざまなillumination is でのパフォーマンス, consumer electricity, スピード, 価格の面においてもOutstanding しています. Examples of parts 検CHECK のスループットの大なUPや, カメラおよびシステムコストの大などを, picture quality を犠生にすることなくすべて実appears できます.

Comparison of CMOS and CCD - Detailed examination of technology

CMOS used to be the most efficient one, and the change efficiency was high in the past.にdissolution されています. オンボードマイクロレンズアレイを is equipped with するなどの IMPROVED により, today's CMOS センサーではCCD センサーと equivalent or above Sensitivity is the same as it is now.

Structurally speaking, the CMOS sensor is very high-quality. Sensitivity is high, the latest technology is high-speed, the technology is high-speed, and the technology is high-speed. このResults, 1 second part number checking, のincrease and clarification of traffic violation images, におけるパフォーマンスがUPしています for each purpose. また, CMOS センサーは多くの occasion フルウェルキャパシティー (saturated capacity) が优れています. フルウェルキャパシティーは1 pixel あたりに containment できる maximum number of electrons であり, フルウェルキャパシティーと sensitivityの比によって, センサーが干できるダイナミックレンジが选まります. つまり, CCD high-sensitivity high-sensitivity である high-sensitivity に対し, CMOS high-sensitivity つまりの difference をカバーし, CCD センサー のダイナミックレンジを実现します. IMX174 camera made by Sony, CCD camera, the last chapter of the camera is a good example of CMOS camera.

A few years ago, the environment was low and the illumination was low. The CCD was suitable for the environment.されていました. しかし Recent CMOS センサーのimage quality は大きくUP しており、CMOS センサーは illuminance がlow いcondition にもsuitable するようになっています.

The illumination is very good and the situation is very good. CMOS is still in good condition. When the CCD camera is exposed excessively, the remainder of the electronic camera is connected to the camera. これによって, the very に明るい in the picture is written in the style and the darkness is written in the style のsquare in the imageます. After the abnormal situation is revealed, the CCD charge is transferred, and the CCD image is drawn, the light is generated, and the situation is generated. この白飞びは「スミア」と火ばれます. Close to the automatic car, the night camera, the camera, the camera, the camera, the camera, the camera, the camera, and the camera. いずれのphenomenonもCMOSセンサーでは発生しません.

Sony company's "Pregius", ON Semiconductor company's "PYTHON", CMOSIS company's "CMV" are equipped with ace モデルのように, the latest CMOS センサー is equipped with カメラには, グローバルシャッター Function equipped with され ています. これにより、ローリングシャッターカメラにおいて発生することのあるアーティファクトがなくなります.

In March 2015, Sony Corporation ceased production of all CCD cameras. これにより, CCD にbased づくtechnology の additional opening 発は间 もなくEnd し, future CMOS にbased づくものにSETきchange えられます.

CMOS technology is completely based on CCD technology.

CMOS センサーは, high-speed motion and high resolution をpreparation, ノイズ performance もimprovement されています. ?

…… …… …… ……?

Sony is not a fool, how could it choose CMOS when CMOS is weaker than CCD

As for Sony’s I don’t know if this point of view is correct, but I know that CMOS is currently the mainstream in the market and CCD basically has no market

…………………………?

Once Many people are indeed not optimistic about CMOS. They once had such a view

CCD

charge coupled device strategy. The original CCD camera was released in Taiwan in 1970 and the CCD camera was released in 1986 (1 million pixels or more).とでPhotographyにも広がりました. CMOS is the default signal, the electronic signal signal is the angle of the signal, the amplifier is the amplifier, and the signal is the signal.

Purpose:

Animation

Small カメラ

メリット: The picture quality is good, the quality is low, and the miniaturization is possible

p>

デメリット：CMOS よりもバッテリーをconsuming する

CMOS

complementary metal-oxide semiconductor. イメージセンサーではありますが, CMOS は実は Semiconductor のなんです. Semiconductor technology, PC technology.

CCD amplifier, CMOS amplifier, CMOS amplifier, CMOS amplifier, CMOS amplifierルに组み込まれています. そのためセンサーのpart of it makes うといったこともpossible, ニコンのカメラに equipped with されている「クロップphotography」はCMOSだから実appearsしています. One glance at the レフのような大きなセンサーで使われています.

メリット：Safety, manufacturing, simplicity, consumption, consumption

デメリット: multi-purpose, miniaturization, difficulty

But today, Human beings have never had the ability to "predict the future". Human beings' predictions about the future are always waiting to be overturned. Only tomorrow will know what tomorrow will bring. The only thing we are doing today is to "gamble" with huge amounts of money. To "bet on a future"

... ... ... ... ...?

Have CMOS achieved miniaturization today? In the future, it will be used in more fields such as automobiles and industrial robots. All use CMOS. As for the question that no matter how advanced the CMOS technology is, CMOS will only get bigger and bigger. The answer now is "NO"

CCD claims to be able to achieve miniaturization, but the reality is that its size is larger Large

As for the noise problem, it may be a problem with CMOS or CCD, but it is more likely to be a problem with the "imaging algorithm". Since there is no conclusion, it is obviously untenable to use this to prove that CCD is better than CMOS. ?

CMOS is cheaper than CCD? I really don’t know this, but I know that the cost of Sony CMOS is about 4 times that of Samsung

So, will the future be dominated by CMOS? How do you know about this problem? I only know that today is the world of CMOS

CMOS is easy to make, is this really the case? The silicon-on-insulator process is currently only known to Sony, and many large manufacturers will give up on CMOS even if they can design CPUs. In fact, the only one that can really do CMOS well is Sony LSI. This is definitely a technical job, Haowei, Samsung and other manufacturers have simply given up

Industrial Internet of Things, autonomous driving, closed-circuit television, unmanned aircraft, medical equipment, industrial robots, etc. all use CMOS. Is the scanning and animation of CMOS poor?

Many manufacturers made the wrong bet back then. They bet on "CCD", which destined them to become losers and even end the sensor business.

In the past, many fields were dominated by CCD, especially in the 20th century. CCD is the only one, but today many fields have been transformed into CMOS, especially the huge emerging fields

The biggest misfortune in the discussion of CCD and CMOS is that the advantages of CCD were once predicted It has gradually become its shortcoming, and the shortcomings of predicting CMOS have basically disappeared. Such huge prediction errors are the root cause of "trap" many manufacturers

A few years ago, many people were optimistic about it CCD, as a result, CCD seemed to disappear out of thin air after 2016, and no one even mentioned the market size of CCD today

Stephane Curral said: "I believe that CMOS will completely replace CCD in the future.

CMOS currently occupies about 70% to 80% of the market share. As CMOS continues to develop and has very obvious cost advantages, it can be said that its future is very bright. Therefore, I think the CCD market will be completely replaced by CMOS in the future, but CCD may still retain a small, very professional and specific application market.

”

…………………………?

Although I can’t see through the future, if I have to compare, I am still optimistic about CMOS (agree with Sony’s point of view), and I don’t believe in CCD even more Comprehensively criticize the "ghost" of CMOS

What do you think? Do you think the future belongs to CMOS or CCD?
