What parameters are related to the camera for the sharpness of the photo?

Mainly, I think there are three aspects:

1. The size of CCD or CMOS, theoretically, the larger the size, the better the imaging effect, and the SLR camera is because the size of CCD or CMOS is close to the film size of the traditional optical camera, so the effect is good.

2. The production process of the lens, the lens generally has a better process than those traditional optical camera manufacturers, especially the German Leica and Carl Zeiss and so on. Mainly some light transmittance and reflectivity and so on.

3. The sensor of the camera is also more critical, and the good effect obtained through the lens and optical sensor does not mean that it is good to stay on the memory card at the end, but it should be stored on the memory card through the perfect processing circuit of the camera.

Lens, Shutter, Aperture **, White Balance!

Key factors affecting the quality of digital ** (hardware part):

1. The size of the CCD area.

Why is the quality of ordinary home digital cameras far inferior to the quality of DSLRs--- is that the CCD area of DSLRs is much larger than that of home cameras. The more light information is received, the clearer it will be.

Generally, the CCD area of ordinary household machines generally has inches and so on. Under the same conditions, a 1-area CCD is of course better than a 1-inch imaging***.

2. The diameter and quality of the lens.

The world's famous brand lenses are highly respected because of the high production quality and good imaging.

The diameter of the lens is large, and the luminous flux is naturally larger than that of the lens with a small diameter, and the amount of luminous flux determines the amount of light information received by the image sensor.

The lenses of home card machines are generally smaller in diameter than those of home portable machines. Therefore, the best quality of the card machine is generally not as good as that of the portable machine of the same grade.

If you have high requirements for image quality, unless you pay more attention to the fashion and thinness of the card machine, you should choose a portable machine.

As far as the digital camera itself is concerned, how well it is imaged depends on three aspects:

1. Optical properties of the lens;

2. The area size and color depth of the image sensor;

3. The level of image processor technology.

**The imaging must be done with the help of the pixels on the sensor, but the clarity is not directly proportional to the height of the pixels. Proportional to the number of pixels is the size of the printing size, the higher the pixel can print, the larger the size of the print. If it's just on a computer**, 10 million pixels are basically the same as 1 million pixels, because the display resolution of the display is only about 800,000 pixels.

Image clarity refers to the clarity of the details and their boundaries on the image.

Sharpness definition. Sharpness, sometimes called "sharpness", is an indicator of the clarity of the image plane and the sharpness of the edges of the image. If you turn the sharpness up, the details on the image plane will also have higher contrast and look sharper.

For example, in the case of high sharpness, not only the wrinkles and spots on the face are clearer, but also the bulging or concave muscles of the face can be vividly expressed. In the other case, where the vertical dark or black lines are abrupt, or where the black and white image is abrupt, in the case of higher sharpness, the edges of the lines or black and white images are abrupt, and the overall picture appears clearer. So, increasing sharpness, in fact, is improving clarity, which is the good side that people need.

However, it's not always better to turn sharpness higher. If you turn the sharpness too high, you will see white lines bordered on either side of the black line, and the image will look distorted and harsh. If this happens on a block image, the image will appear severely distorted and unsightly.

For example, if this happens in a small image of a face, there will be white trim not only on the edges of the face, but also on the black and shadowed areas such as hairline, eyebrows, eye sockets, nose, and lips, which will look unpleasant. It can be seen that although too high sharpness improves the clarity, it will distort the shape, which is also not a good thing. Therefore, in order to obtain a relatively clear and realistic image, the sharpness should be adjusted appropriately.

The main factors that determine the clarity are:

1The quality, size, and pixels of the camera's sensor.

2. The resolution of the lens (that is, the quality of the lens).

3. The distance of the shooting distance.

4. Accuracy of focusing.

5** Format and size of storage.

6. Good light.

7 Accurate**.

The phenomenon you are talking about is only one factor that affects the clarity.

And it's not the most important factor, so it's normal for that to happen, for example: playing with a DSLR pixel 600.

Its file size is set to 2M

The sharpness of the ** shot to achieve the above 2---7 conditions is definitely better than a card player with 10 million pixels.

in 3M file size.

Shoot much sharper under the same conditions (except for lens resolution), why?

Because of the SLR machine.

The size and quality of the sensor.

And the resolution of the lens is much better than that of the card machine.

Problem description: I want to ask: In addition to the pixels of the mobile phone camera, the clarity of mobile phone photography is also related to what factors? Can a high-pixel mobile phone shoot the same quality as a digital camera?

Analysis: In addition to the relationship with the lens, it is also related to the screen of your mobile phone, if your lens is very good, but the screen is very rubbish, it looks like the photo is very blurry or something, in fact, sometimes** or the photo is good! Also, if you use a 500W pixel, autofocus, white balance, and anti-shake mobile phone, it won't lose to two or three million digital cameras!

Generally speaking, the current K790 is very good! You use to wash 3,5 inches**, you can't tell which one is taken by a mobile phone, and the other is taken by a digital camera!

Aside from the quality of the lens and the quality of the photographic technique.

For digital cameras, the reason for determining the clarity of a photo is the number of pixels of the sensor and the effective size of the sensor. The latter is all the more important. For example, the more high-end the camera, the larger the sensor size, the best or worse and the camera grade from good to bad, medium format camera, full-frame SLR, half-frame SLR, professional portable (1, consumer camera (1, mobile phone camera.

Digital cameras have developed to this day, the number of pixels is no longer a problem, at most it is a sensational concept, for example, the pixels of card machines are generally 1400W or 1600W, while quasi-professional portable computers are in the early 1000W, and its sensor has a larger size. The so-called layman looks at the liveliness, what he sees is how many pixels, and the insider's look at the doorway, he understands that digital is more important.

Good luck.

Camera vibration caused by hand shake. The shutter speed is too low, resulting in the moving object being shot not being frozen.

**Whether it is appropriate or not, too dark or too bright will not be clear. Focus is not accurate, and the outside of focus is generally blurry at wide apertures.

The number of pixels only determines how far ** can be enlarged without distortion.

Pixels are just hardware, and they will only shoot well if they can be used.

Pixels are one of the factors that determine the clarity of a photo... There are also the number of acquisition points and the degree of lens analysis, but the pixels are the main factor.

I don't understand, I don't know anything, I'm misleading newcomers here. If the shot is not clear, then there are several possibilities, one, the camera vibration caused by hand shake. Second, the shutter speed is too low, resulting in the shooting of moving objects cannot be frozen.

Third, whether it is appropriate, too dark or too bright will not be clear. Fourth, the focus is not accurate, and the part outside the focus is generally blurry under a wide aperture. That's about it, what is certain is that the number of pixels only determines how much you can enlarge this ** without distortion.

A million pixels and 10 million pixels are basically indistinguishable in the palm of your hand. Once you understand the basics of photography, let's answer others. Otherwise, everyone will think so, wouldn't the three of them become tigers.

The clarity of a photo is mainly determined by the lens, pixels, and sensitivity. The better the quality of the lens, the higher the pixels, and the lower the sensitivity, the clearer it will be.

In the case of film, the sharpness is determined by the size of the photosensitive particles (silver salt grains), and in terms of sensitivity, 25 has the highest definition and 800 has the lowest.

In the case of digital**, the sharpness is determined by the density of the sensor, which can also be said to be determined by the pixels.

1. How many pixels are in the digital camera.

2. The area size of the digital camera imaging device.

3. Image processing chip.

On digital cameras, there are many factors that can affect sharpness.

Image sensor size. In simple terms, it is equivalent to the size of a baseplate. Why is the DSLR camera clearer than the phone?

The image sensor of mobile phones is generally 1, which is about half the size of an adult man's thumb nail. When taking a photo, the light in the current scene is focused on the image sensor, and the larger the sensor, the more detail is retained, and the less detail is compressed. When zoomed in, the larger the sensor, the larger the image-sensitive sensor.

For example, the ** of ordinary card cameras is generally magnified to a maximum of 15 inches, and more than 15 inches** will appear unclear, and blurred points can be seen. Some SLR mirrorless mirrors can be magnified to more than 80 inches, full frame, and the image sensor is 36x24mm, which can be magnified even more. Of course, the highest image quality should be set in the camera.

For aero-optical equipment such as the Hubble telescope, the image sensor must be above 8m and 10m, so that the Great Wall can be photographed clearly at high altitude.

On the basis of the same image sensor, the sharpness of the corresponding lens should be looked at first. That is, the ability of the lens to resolve the current scene. In the same scene, the sharpness of most prime lenses is higher than that of zoom lenses, because there are fewer lens groups inside the prime lens, and less light is lost.

The higher the sharpness, the more detail you can see. This already falls under the category of interchangeable-lens cameras.

Third, it depends on whether there is special optical equipment. For example, the D800 D800E, RX1 RX1R, which are hot on the market. The special feature of these two product lines is that the effect of adding a low-pass filter and removing a low-pass filter or removing a low-pass filter are respectively.

The disadvantage of removing the low-pass filter is that moiré and false colors are not avoided, and the advantage is that higher sharpness can be obtained. Because the principle of the low-pass filter is similar to smearing the details of the picture, removing moiré and false colors. Cameras with the low-pass filter removed are mainly for landscape photography, which can achieve higher sharpness and retain more detail in **.

The low-pass filter is used to prepare for scenes such as humanities (moiré patterns are easy to produce due to repetitive stripes such as clothing).

Finally, look at the processor of the camera itself. At present, mainstream digital cameras have an independent processing unit, just like the CPU of a computer, to deal with the problem of image quality and clarity such as noise generated during the shooting process.

Basically, these are the main factors. If you have any further questions, please ask. Hope it helps, thank you

**Clarity -

It has to do with the effective pixels of the lens itself.

It has to do with ambient light.

It depends on the focus position and shutter speed (whether it shakes when pressed).

Whether the lens is clean or not.

And then there is something to do with looking at the ** display haha.

The first is the sharpness of each sensor, the DSLR's image processor, the focus area, and the shutter speed when shooting.

pixels, and then it should be static and clearer, and the professional ones don't know.

pixels as well as sharpness.

It is related to time, depth of field, etc.
