Camera interpolation, why and what is it? What is camera interpolation on an Android smartphone? What does interpolation camera mean?

P2P camera- IP camera containing software, which allows you to identify it and connect to the camera remotely by a unique number (ID number) without using a static IP address or functions such as DDNS and UPnPct. P2P cameras were designed to make it easier for ordinary non-specialist users to set up remote camera access.

How P2P Camera Works

When a p2p camera is connected to the Internet (via a router or 3G connection), the camera automatically sends a request to a remote server that identifies the camera by its unique ID number. To access the camera and view the video, the user needs to install on the device (computer or mobile devices) a special application from the developer of the IP camera. AT this application the user enters the camera ID (or takes a photo of the camera's QR code so as not to enter the code manually), and then can view the video from the camera online, view the video archive from the SD card, control the PTZ device and use other functions. The server in this case acts as an intermediary connecting the IP camera and the user's device directly.

Why P2P technology is needed

This technology is designed to make installation of the IP camera as easy as possible for the end user. Without this technology, in order to remotely access the camera, the user needs to connect a static IP address or have special skills. In the case of P2P cameras, a typical user spends no more than 10 minutes installing the camera and setting up remote viewing.

Applications for P2P Cameras

P2P cameras allow you to get a complete video surveillance system with remote access from anywhere in the world and easy to install for little money. The main areas of application for P2P cameras:

• surveillance of a country house and / or plot
• home security surveillance
• pet surveillance
• small business security and point of sale surveillance
• patient monitoring
• use in state and municipal institutions, etc.

P2P camera companies

The world leader in the production of P2P cameras is Cisco.

What does "5.0MP interpolation" and "8.0MP interpolation" mean?

In description Smartphone DOOGEE X5 discovered an interesting and, at the same time, incomprehensible moment:
Dual cameras: 2.0MP (5.0MP interpolation) front camera; 5.0MP (8.0MP interpolation) Rear camera with flash and auto focus.

What does "5.0MP interpolation" and "8.0MP interpolation" mean?
Really how many megapixel cameras - 2 and 5 megapixel or 5 and 8 megapixel?

living creature

It means "FUCKING" ... shitty cameras are passed off as high-quality ones ... 2MP camera programmatically produces a 5MP image ... they try to sell you a fake ... original DVRs do not use interpolation ...

Vladssto

This means that the camera physically has a real resolution of, say, 5MP, and the smartphone has software that pushes neighboring pixels and draws between them another pixel in color, something in between the neighboring ones, and the output is already a photo with a resolution of 8MP.
This does not particularly affect the quality, just a photo with a higher resolution can be zoomed in more, view the details

The smartphone has an 8 MPix camera. What does interpolation up to 13 MPix mean?

Sergey 5

Up to 13 MPix - it can be 8 MPix real, like yours. Or 5 MPix real ones. The camera software interpolates the graphic product of the camera up to 13 MPix without enhancing the images, but electronically enlarging it. Simply speaking, like a magnifying glass or binoculars. The quality doesn't change.

This means that the camera can take a picture up to 8 MPIX, but it can programmatically increase pictures up to 12 MPIX. So it programmatically increases, but the image does not become better, the image will still be exactly 8 MPIX. This is purely a trick of the manufacturer and such smartphones are more expensive.

Consumer

To explain in a simple way, when creating a photo, the smart processor adds its own pixels to the active pixels of the matrix, as it were, it calculates the picture and draws it up to a size of 13 MP .. At the output, we have a matrix of 8 and a photo with a resolution of 13 MP. The quality doesn't improve much.

Violet a

Camera interpolation is a trick of the manufacturer, so they artificially inflate the price of a smartphone.

If you have an 8 MPIX camera, then it can take a corresponding picture, interpolation does not improve the quality of the photo, it simply increases the size of the photo to 13 megapixels.

The USSR

Megapixel interpolation is a kind of software smearing of a picture. Real pixels are moved apart, and additional ones are inserted between them, with the color of the average value from the colors moved apart. Nonsense, useless self-deception. The quality does not improve.

Mastermiha

On Chinese smartphones this is now used all the time, it’s just that a 13mp camera sensor costs much more than an 8mp one, which is why they put it on 8mp, but the camera application stretches the resulting image, as a result, the quality of these 13mp will be noticeably worse if you look at the original resolution.

In my opinion, this function is generally useless, since 8mp is quite enough for a smartphone, in principle, 3mp is enough for me, the main thing is that the camera itself is of high quality.

Azamatik

Good day.

This means that your smartphone will stretch the photo/image taken with the 8 MPix camera to 13 MPix. And this is done by the fact that real pixels are moved apart and additional ones are inserted.

But, if we compare the quality of the image / photo taken at 13 MP and 8 MP with interpolation up to 13, then the quality of the second will be noticeably worse.

Doubloon

This means that in your cell, as there were 8 MPIX, they remain the same - no more and no less, and everything else is a marketing ploy, a scientific fooling of the people in order to sell goods at a higher price and no more. This function worthless, when interpolating the quality of the photo is lost.

Moreljuba

This concept implies that the camera of your device will still take photos at 8 MPIX, but now it is possible to programmatically increase it to 13 MPIX. At the same time, the quality does not become better. It's just that the space between the pixels is clogged, that's all.

Interpolation is a way of finding intermediate values

If all this is translated into a more human language, applicable to your question, then the following will turn out:

• the software can process (enlarge, stretch)) files up to 13 MPIX.

Marlena

The fact is that the real camera in such phones is 8 megapixels. But with the help of internal programs, the image is stretched to 13 megapixels. In fact, it does not reach the real 13 megapixels.

Camera interpolation is an artificial increase in image resolution. It is the image, not the size of the matrix. That is, this is special software, thanks to which an image with a resolution of 8 megapixels is interpolated to 13 megapixels or more (or less). In an analogy, camera interpolation is like a magnifying glass or binoculars. These devices enlarge the image, but do not make it better or more detailed. So if interpolation is indicated in the characteristics of the phone, then the actual resolution of the camera may be lower than the declared one. It's not bad or good, it just is.

Interpolation was invented to increase the size of the image, nothing more. Now this is a ploy by marketers and manufacturers who are trying to sell the product. They use large numbers to indicate the resolution of the phone's camera on the advertising poster and position it as an advantage or something good. Not only does the resolution itself not affect the quality of the photos, but it can also be interpolated.

Literally 3-4 years ago, many manufacturers were chasing the number of megapixels and different ways tried to cram them into their smartphones with as many sensors as possible. This is how smartphones with cameras with a resolution of 5, 8, 12, 15, 21 megapixels appeared. At the same time, they could take pictures like the cheapest soap dishes, but buyers, having seen the sticker "18 MP camera", immediately wanted to buy such a phone. With the advent of interpolation, it has become easier to sell such smartphones due to the possibility of artificially adding megapixels to the camera. Of course, the quality of the photo began to improve over time, but definitely not due to resolution or interpolation, but due to natural progress in terms of sensor and software development.

What is camera interpolation in a phone technically, because all the text above described only the main idea?

With the help of special software, new pixels are "drawn" on the image. For example, to enlarge an image by 2 times, a new line is added after each line of image pixels. Each pixel in this new row is filled with a color. The fill color is calculated by a special algorithm. The very first way is to fill the new line with the colors that the nearest pixels have. The result of such processing will be terrible, but such a method requires a minimum of computational operations.

The most commonly used method is another. That is, new rows of pixels are added to the original image. Each pixel is filled with a color, which, in turn, is calculated as the average of neighboring pixels. This method gives the best results, but requires more computational operations. Good, modern mobile processors are fast, and in practice the user does not notice how the program edits the image, trying to artificially increase its size. smartphone camera interpolation There are many advanced interpolation methods and algorithms that are constantly being improved: the transition boundaries between colors are improved, the lines become more accurate and clear. It doesn't matter how all these algorithms are built. The very idea of ​​camera interpolation is banal and is unlikely to take root in the near future. With interpolation, it is not possible to make an image more detailed, add new details, or improve it in any other way. Only in films does a small blurry picture become clear after applying a couple of filters. In practice, this cannot be.

The built-in camera is not the last thing when choosing a smartphone. For many, this parameter is important, so when looking for a new smartphone, many people look at how many megapixels are declared in the camera. At the same time, knowledgeable people know that it's not about them. So let's look at what you need to pay attention to when choosing a smartphone with a good camera.

How the smartphone will shoot depends on which camera module is installed in it. It looks like in the photo (the modules of the front and main cameras look about the same). It is easily placed in the case of a smartphone and, as a rule, is attached with a cable. This method makes it easy to replace in case of breakage.

The monopoly in the market is Sony. It is her cameras, in the vast majority, that are used in smartphones. OmniVision and Samsung are also in production.

The manufacturer of the smartphone is also important. In fact, a lot depends on the brand, and a self-respecting company will equip its device with a really good camera. But let's see what determines the quality of shooting a smartphone point by point.

CPU

Are you surprised? It is the processor that will start processing the image when it receives data from the photomatrix. No matter how high-quality the matrix is, a weak processor will not be able to process and convert the information that it receives from it. This applies not only to video recording in high resolution and fast frames per second, but also creating high-resolution images.

Of course, the more frames per second changes, the greater the load on the processor.

Among people who understand phones, or who think that they understand, there is an opinion that smartphones with American Qualcomm processors shoot better than smartphones with Taiwanese MediaTek processors. I will not deny or confirm this. Well, the fact that there are no smartphones with excellent cameras on low-performance Chinese Spreadtrum processors, as of 2016, is already a fact.

Number of megapixels

The picture consists of pixels (dots) that are formed by the photomatrix during shooting. Of course, the more pixels, the better the image should be, the higher its clarity. In cameras, this parameter is indicated as megapixels.

Megapixels (Mp, Mpx, Mpix) - an indicator of the resolution of photos and videos (number of pixels). One megapixel is one million pixels.

Take, for example, the Fly IQ4516 Tornado Slim smartphone. It takes photos at a maximum resolution of 3264x2448 pixels (3264 color dots in width and 2448 in height). Multiply 3264 pixels by 2448 pixels, we get 7,990,272 pixels. The number is large, so it is translated into Mega. That is, the number 7,990,272 pixels is approximately 8 million pixels, that is, 8 megapixels.

In theory, more squeaks means a clearer photo. But don't forget about noise, worse shooting in low light, etc.

Interpolation

Unfortunately, many Chinese smartphone manufacturers do not disdain software increase in resolution. This is called interpolation. When the camera can take a picture at a maximum resolution of 8 megapixels, and it is programmatically increased to 13 megapixels. Of course, this does not improve the quality. How not to be deceived in such a case? Search the Internet for information about which camera module is used in the smartphone. The characteristics of the module indicate in what resolution it shoots. If you did not find information about the module, there is already a reason to be wary. Sometimes it can be honestly stated in the specifications of a smartphone that the camera is interpolated, for example, from 13 MP to 16 MP.

Software

Do not underestimate the software that processes a digital image and presents it to us in the final form as we see it on the screen. It detects colors, eliminates noise, provides image stabilization (when the smartphone in your hand twitches when shooting), etc. Not to mention the various shooting modes.

Camera matrix

The type of matrix (CCD or CMOS) and its size are important. It is she who captures the image and transfers it to the processor for processing. The resolution of the camera depends on the matrix.

Aperture (aperture)

When choosing a smartphone with a good camera, you should pay attention to this parameter. Roughly speaking, it indicates how much light the matrix receives through the optics of the module. The bigger, the better. Less set, more noise. Aperture is denoted by the letter F followed by a slash (/). After the slash and the aperture value is indicated, and the smaller it is, the better. As an example, it is indicated as follows: F / 2.2, F / 1.9. Often listed in technical specifications smartphone.

A camera with an f/1.9 aperture will perform better in low light than a camera with an aperture of f/2.2, since it will let more light into the sensor. But stabilization is also important, both software and optical.

Optical stabilization

Smartphones are rarely equipped with optical stabilization. As a rule, these are expensive devices with an advanced camera. Such a device can be called a camera phone.

Shooting with a smartphone is carried out with a movable arm and so that the image is not blurry, optical stabilization is applied. Maybe hybrid stabilization (software + optical). Optical stabilization is especially important at slow shutter speeds, when, due to insufficient lighting, a picture can be taken for 1-3 seconds in a special mode.

Flash

The flash can be LED and xenon. The latter will provide much better photos in low light. There is a dual LED flash. Rarely, but there may be two: LED and xenon. This is the best option. Implemented in the Samsung M8910 Pixon12 camera phone.

As you can see, how the smartphone will shoot depends on many parameters. So when choosing, in the characteristics you should pay attention to the name of the module, aperture, and the presence of optical stabilization. Your best bet is to look for reviews of a specific phone on the Internet, where you can see sample shots, as well as the author's opinion about the camera.
