Want to know how big is the difference between a digital camera CCD size 1 1 7 and 1 2 3 inches? 10

Of course, 1 inch has a higher imaging accuracy than 1 inch. Regardless of whether the pixels of the two cameras are the same or not, the imaging accuracy of a camera with a large CCD size is high.

1 inch is inches, approx.

1 inch is inches, approx.

When buying a camera, it is more important to look at the CCD size than to see the number of pixels. When the pixel is not high, as long as the CCD size is large and the imaging is clear, the computer can be used to expand the interpolation to a large number of pixels. And the small CCD size shooting**, even if the pixels are enlarged, it is still not clear.

The Canon 980 is clearly better than the 870. It is recommended to buy the 980 model.

The larger the CCD size, the better the image, but depending on how many megapixels of 870 and 980 differ: 870 10 million pixels 28mm wide angle 4x light variation 980 14.7 million pixels of zoom (and not very clear).

For example, if you have too high pixels at home, it is useless (in fact, 8 million is enough at home) The camera with a wide angle shoots a larger field of view, for example, if you go to shoot a tower, you may not be able to shoot the spire without a wide angle, and you can shoot it with a wide angle. That's the benefit of wide angles. There are also many people who shoot more with friends at home, and 980 has some manual functions, if you have a foundation in this area, you can consider 980

I recommend you 870 for more home use.

The area of 1 is large, and the image quality is a little better than that of 1.

CCD size is very important for imaging quality and quality, it is one of the most important parameters, if the difference is not big, or choose a larger CCD.

In general, the larger the CCD size, the better the image quality.

The fidelity is not the same.

The sensor sizes you list here are all the sizes of common card machine sensors on the market today.

In general, the heavier the rain, the better.

Of these, 2 3 inches is the largest, and theoretically its imaging should be the best under all equal conditions.

This is followed by 1 inch, 1 inch, 1 inch, 1 inch.

DSLR cameras can be roughly divided into two categories according to the sensor size, one is full-frame and the other is half-frame.

EOS1D is not mentioned yet).

Under the same conditions, the larger the sensor size, the better the image quality.

That is, full-frame is better than half-frame (APS-C format).

However, full-frame cameras are currently only available in SLR cameras, and the current market price of a single body (excluding lenses) is not lower than 14,000 yuan.

For the same pixel, the larger the sensor, that is, the larger the area of a single pixel, the stronger its ability to receive optical signals, so the signal-to-noise ratio is improved, and the better the image quality obtained.

However, the size of the sensor is also directly proportional to its design and production cost.

The bigger, the better and the more expensive.

This is a historical problem, probably dating back to the twentieth century.

In the fifties and sixties, when electronic imaging technology was just beginning, the image sensor used in the early TV cameras was a vacuum tube, and the CCD and CMOS sensors that are common now had not yet been invented at that time There is a glass cover on the outside of the vacuum tube, and the outer diameter of the vacuum tube is to include the thickness of the glass Of course, the glass tube cannot be used for imaging, so the actual imaging area of the vacuum tube with an outer diameter of 1 inch is only about 16mm. So 16mm has become a conventional unit of measurement in the vertical electronic camera fiber spine photography industry Although the vacuum tube imaging technology is no longer used, this measurement method has been inherited So now the unit of inches mentioned in the digital imaging element cannot be calculated according to the industrial standard of 1 inch = , but 1 inch = 16mm.

Of course, the size of (1 2) is large, and the sensor size is large. CMOS has low power consumption, and the process has caught up with CCD.

CMOS refers to the manufacturing process of complementary MOS integrated circuits composed of complementary metal oxides (PMOS tubes and NMOS tubes), which is characterized by low power consumption. Since the gate circuit consisting of a pair of MOS in CMOS is either PMOS on, nmOS on, or both instantaneous, it is much more efficient than a linear triode (BJT), so the power consumption is very low.

CCD, English full name: charge-coupled device, Chinese full name: charge coupled element. It can be called a CCD image sensor. A CCD is a semiconductor device that converts optical images into digital signals.

The above information comes from Youdao.

The larger the area, the more light sensitivity, and the larger the size, the higher the resolution in the case of similar process grades.

Naturally, bigger is better.

The larger the sensor, the less dense the pixel distribution, the higher the signal-to-noise ratio, the less noise appears, and the clearer and purer the image in low light and high sensitivity.

You've listed the size of the sensor (diagonal length) for the card and telephoto cameras.

DSLRs don't have such a small sensor, and the smallest 4 3 system cameras also have 4 3 inches (the image circle diameter is 4 3 inches, and the diagonal of the sensor is shorter, about 22mm). At present, the mainstream is APS format and full-frame SLR, to this size, generally do not use inches as a unit, APS sensor is or, the full frame is 36*24mm.

As with any sensor, bigger is better. Of course, the bigger the cost, the higher the cost, and the more difficult it is to design the lens, the volume and weight of the lens will also increase, and the geometric progression will soar.

1 inch =, you can convert and compare it yourself.

The size of the SLR must be more than a dozen times more than a dozen such data, only the card machine will have a fraction. The larger the sensor size, the better the imaging. If it's a card machine, imaging at this size of 1 is definitely the best.

The bigger the sensor size, the better it must be 23 of the best.

CCD is a photosensitive component, which is a photoelectric sensor that converts optical signals into electrical signals and processes them into digital images at the back end.

The size you're talking about is for area array CCD chips.

The CCD sensor chip has a light-sensitive area, and the size of this light-sensitive area is measured in inches.

For example, 1 2 inches means that the length of the diagonal of the photosensitive area is inches. The same goes for 1 inch, the length of the diagonal.

The higher the value, the larger the CCD's sensitive area.

The larger the photosensitive area, the higher the resolution of the sensor, millions of pixels. As a result, the resolution of the ** will also be very high.

The larger the sensitive area, the larger the pixel size of a single dot. This increases the sensor's ability to influence in low-light conditions.

Category: Electronic Digital.

Analysis: The size of the CCD is actually the length of the diagonal line of the CCD.

At present, 4 million pixels or 5 million pixels of digital cameras generally use 1 inch, 1 inch and 1 inch size is the light receiving element (pixel) **body, receive the light through the lens and convert it into an electrical signal. In the case of the same number of pixels, the larger the CCD size, the larger the unit of pixels. In this way, more light can be collected per unit of pixel, so it can theoretically be said to be beneficial for improving image quality.

Of course, the quality of a digital camera is not just determined by the CCD. The performance of the lens and the circuits that form images through the electrical signals output from the CCD can also affect the image quality of the camera. The so-called "large size CCD high image quality" is incorrect.

For example, although 1-inch is smaller than 1-inch, digital cameras with 1-inch CCDs have not been criticized for poor picture quality.

Nowadays, pocket digital cameras are becoming smaller and lighter, and most of them use small 1-inch CCDs for design reasons.

By the way, the 1-inch "type" is sometimes written "inch", however, it is not the ordinary "1-inch" here. Due to the combination of the camera tube and display used on the camera before the CCD debut, it is customary to use a relatively special size. 1 inch is, 1 inch is about 9mm. The first hail.
