For the camera, it doesn t matter how many pixels weigh

The most important thing for the camera is the sensor, and the quality of the sensor is related to the quality of a ** or a **. At present, there are two kinds of sensors on the market, CCD and CMOS, and I personally think that CCD is better than CMOS, so let's talk about CCD to tell you about the role of pixels.

CCD image sensor. A CCD is a semiconductor device that converts optical images into digital signals. The tiny light-sensitive substance implanted in the CCD is called a pixel.

The more pixels a CCD contains, the higher the resolution of the picture it provides, and there are many indicators to measure the quality of CCD, including the number of pixels, CCD size [2], sensitivity, signal-to-noise ratio, etc., among which the number of pixels and CCD size are important indicators. The number of pixels refers to the number of sensors on the CCD. The image captured by the camera can be understood as consisting of many small dots, each of which is a pixel.

Obviously, the more pixels you have, the clearer the picture will be, and if the CCD doesn't have enough pixels, the sharpness of the captured image will be greatly affected, so theoretically, the more pixels the CCD has, the better. However, the increase in the number of CCD pixels will reduce the manufacturing cost and the yield rate, the key points: (and under the current TV standard, after the number of pixels increases to a certain number, the improvement effect of increasing the clarity of the shooting picture becomes not obvious, therefore, the number of pixels of about one million pixels is enough for general use.)

For example, you can only eat 2 bowls per meal, and then you are given 20 bowls of rice per meal, and the extra 18 bowls of rice are useless for you.

Here are some articles about your problem, you can see for yourself, it should help you with your confusion.

Pixels play a key role in the quality of the **.

A high-pixel camera also means that higher quality, sharper images can be taken, and the camera's pixels are the smallest units that make up an image.

In image recording, a single pixel represents a point of color, which means that each pixel can display a different color. Shooting with the same composition, a high-pixel camera can make the lens divided into several parts, so that each pixel can more accurately capture more realistic colors and clear content. The ** shot by the high-pixel camera can present a very high texture, and for the videographer, the high-quality work can win more praise.

And a high-pixel camera can bring higher sharpness to photography.

It is a great way to enhance the look and feel of photography. <>

The camera resolution usually refers to the output pixels of the camera, and the unit of resolution is dpi, which refers to the pixel value per inch of the printed matter. That is, the higher the value, the better the accuracy of the printout**. Different print types have different print resolution requirements.

At this time, if you need large-format, high-precision printing, then you need to need higher pixels. <>

Compared to low pixels, even if a portion of the pixel is cropped, the overall area is still higher than the low pixel. As a result, photos taken with high-resolution cameras have higher cropping flexibility than low-resolution images. This also means that even if you encounter an inappropriate composition in a high-pixel shot, you can also crop it with more advantages in the later stage, because cropping will sacrifice the pixel value.

High-resolution** provides more flexible cropping than low-resolution images, allowing you to retain higher-pixel images even if most of them have been cropped. The pixel is the smallest sensor unit in the camera photosensitive device, which is the basis of digital images, and high pixel value has always been the common development direction of camera manufacturers. Digital cameras.

The pixel value has also grown from the earliest 350,000 pixels to today's mainstream 30 million pixels. <>

I think it's important because the pixel level directly determines the final clarity of the photo.

I don't think it's really important, the most important thing in photography is the gimbal function, which can greatly improve the image clarity.

Mobile phone pixels can meet the needs of people in daily life photography, and now mobile phones are getting higher and higher, and can even replace cameras. It is very important in life.

This shows that pixels are not the only factor that determines a camera's performance, or even not.

There are many factors that determine the grade and quality of the SLR body, first of all, the sensor size (not the number of pixels), and then the workmanship of the body, viewfinder performance, metering and focusing module, in-camera processor performance, shutter speed, continuous shooting speed, etc.

For most shooting purposes, and even for many professional uses, 16 million pixels is actually sufficient.

The DSLR sensor has a large area, and improving the pixels can effectively improve the details of the picture, but at the same time, it will also bring the problem of declining high-sensitivity image quality, increasing the burden of data processing in the machine, and increasing the requirements for lens imaging quality.

If you just play with the mobile phone card machine, it doesn't matter if you think so, but since you are ready to start a DSLR, then you should abandon the superficial understanding of pixel determinism and enter a deeper understanding of digital photography.

The number of pixels is the number of photosensitive elements on the sensor of the photosensitive material of the digital camera.

In the early days, due to the limitations of sensor manufacturing technology, the number of pixels in the sensor was relatively low, and increasing the number of pixels would significantly improve the image quality, so high pixels were pursued at that time. With the gradual improvement of chip engraving technology, the number of pixels of the sensor is also gradually increasing, when the number of pixels of the APS-C format (about 24x16mm) sensor reaches more than 10 million, as long as it is not a large enlargement, increasing the number of pixels has no effect on improving the image quality - I can't see it.

Based on the above reasons, the number of pixels in the sensor of the APS-C format SLR released in the past two years has exceeded 16 million, and the number of pixels is no longer an important indicator to measure the quality of a DSLR camera.

Pixels do not determine the performance of SLR, and generally 10 million pixels are basically enough, unless you want to show a large **.

As long as the body performance of the SLR is focused and controlled, the image quality of the sensor of the same size is mainly determined by the lens, of course, it also has a certain relationship with the sensor, for example, the Nikon D3200 (24.16 million pixels) priced at 3,000 yuan and the Nikon D3 (12.1 million pixels) priced at 30,000 pieces are not of the same level.

10 million pixels for daily use is more than enough.

Pixel size is independent of quality. The pixel size is only related to the ** size. **Quality is determined by the sensor.

Generally, the image sensor of ordinary consumer-grade digital cameras is CCD, and the size is expressed as a reciprocal, and the larger the value, the better the image quality, for example, 1 inch is more delicate than 1 inch. DSLRs and professional cameras have much larger image sensors than conventional cameras, and the image sensors used are better than those of CCDs, resulting in better image quality.

For printing ordinary 6 inches**, 5 million pixels is more than enough, so 14 million pixels are enough for daily use.

The number of pixels corresponds to the ** quality definitely has an impact, but it includes both positive and negative effects.

Positive impact: The higher the pixels, the larger the image size that can be output, and the better the image detail performance, such as the Canon 5DII has more than 20 million pixels, and the details of shooting landscapes** are very good. However, this also requires the support of high-quality resolution lenses.

Negative effects: In the case of a certain sensor format (and the same sensor manufacturing process), the higher the pixel density, the smaller the lighting area of a single pixel, which will cause the signal-to-noise ratio of the sensor to be greatly reduced, which is manifested as an increase in high ISO noise. Boot in-camera noise reduction reduces noise, but it loses image detail.

In particular, small portable digital cameras generally use small-area CCD (less than 1 inch), and the highest pixel can reach 16 million, which is just a marketing method for manufacturers, and the negative impact is far greater than the positive impact. The most direct example is high-end digital cameras such as the Canon G12 and Panasonic LX5, which use a larger 1-inch CCD with only 10 million pixels, in order to increase the available ISO sensitivity and ensure a balance in image quality. The manufacturing process of the new back-illuminated CMOS sensor is improved, and the opening area of the pixel lens is large, which has a certain improvement in the signal-to-noise ratio.

To sum up, the average small digital camera, 10 million pixels is enough to output A4 paper size, and there is no need to pursue higher pixels. For a 14-million-pixel (1-inch CCD) machine, high ISO image quality has a greater negative impact, so it's best to check the detailed instructions, and if there is a binning pixel function in low light, it is more practical (such as shooting with 6 million or even 3 million pixels in low light).

The pixels of a digital camera directly affect the pixels, and the larger the pixels, the larger the size.

The quality of ** is not only related to pixels, but also designed to brightness, contrast, clarity, color accuracy, whether there are color edges, etc., which depends on the most important component in the cameraCCD card, a good 600W pixel may be ***** than a poor 1000W camera**. So don't just think about the pixels of the camera.

Therefore, just for general photography, 5 million pixels is sufficient.

The higher the pixels, the better and sharper the quality and the larger the itself.

If you magnify the **, you can see the gap.

14 million pixels is very good, enough to play by yourself.

After 2007, such a problem should not arise again.

1. Put the computer to look at the photo, how many times have you zoomed in to the original pixel to see it? Your monitor will only have a resolution of 2 million pixels at most.

2. To wash photos, will you take the photos taken by the card machine to wash 15-inch photos? 3,000,000 pixels is enough for you to wash your daily photos.

3. The higher the pixel, the better? For cameras with large sensors such as non-single electric and DSLR cameras, the higher the pixels, the more noise. Even if the 16 million pixels are compressed to 8 million pixels after shooting, it is not as good as directly shooting 8 million pixels.

Therefore, buy a camera now and put an end to the parameter of looking at pixels, especially home cameras. When the pixels of the home camera reach 8 million pixels, you can buy it. Don't be afraid to compare pixels in front of others, if someone asks you how many pixels you have, you can ask them "what is the sensor size".

Image quality is largely determined by sensor size.

No, it's just suitable, in fact, it depends on the size of the CCD. The digital cameras on the market are generally 12 million and 14 million, and there are no others, and there is basically no difference in the photo effect. Sometimes high pixels are not necessarily good, so when buying a camera, you can look at other parameters such as optical zoom instead of looking at pixels.

The pixel and CCD size should be matched, for example, the CCD of the two cameras is the same size, and the smaller the pixel, the better the image quality. So high-resolution phones are a joke.

Not absolutely. The finer the imaging is higher with a large number of pixels, but the most important thing is that the one that suits you is the best. If you can't do it, no matter how good the camera is, no matter how large the pixels are, you can't create a wonderful **.
