What are the pixels and resolution of a digital camera?

The so-called "pixels" of a digital camera refer to the "resolution" of pictures that can be seen on our computer monitors, and that's what it means.

What is the resolution? It is the display size on your computer. For example, you usually use 800X600 or 1024X768 when viewing web pages.

An 800,000-pixel digital camera can take a picture with a length of 1024 and a height of 768 (resolution) (meaning 80 Vientiane digital camera photos can fill the screen on your monitor.

A 3-megapixel digital camera can take photos with a length of 2048 and a height of 1536. You have to drag the scroll bar to browse. Each part of the image

The size of 4 million to 5 million is even larger

Pixels refer to the size of the picture (it has nothing to do with the photo quality)

Pixels - Resolution = picture size (don’t think that pixels and resolution are image sharpness)

If you still don’t understand, just read below

The size of the photos taken by a 2-megapixel camera is generally large ( Viewed on the monitor)

The photo taken by the 3-megapixel camera is larger (viewed on the monitor)

The photo taken by the 5-megapixel camera (viewed on the monitor) It’s huge

The photos taken by the 10-megapixel camera (viewed on the monitor) are huge

That’s what it means~

You use a The maximum size (pixels) that a 2-megapixel digital camera can take is a photo with a length of 1600 and a height of 1200. After transferring it to the computer, use software to enlarge the image to 2048X1536. You can also say that this picture is a 3-megapixel picture (this means It’s called software interpolation)

There are many cameras that say (this is what it means to interpolate from 1 million to 2 million)

For example, many Fuji cameras use 3 million to interpolate to 6 million

In fact, the quality of the enlarged image is not as good as the original image, and it has no practical significance.

Then you will understand what pixels are!

So it is necessary to buy a digital camera. You need to check the photo quality of the camera you want to buy.

It is not feasible to just look at the pixels blindly.

As long as the image is taken by an 80-megapixel digital camera, With software, you can enlarge to 10 million images... 20 million images... But when you look at the enlarged picture, you will feel... dizzy

Pixels = image How good is the quality? How about taking a look at the photos of the digital camera you want to buy? For example, two 4-megapixel digital cameras of different brands, in the same location and with the same light. (Under the same photographic conditions) their image quality is different.

That is the detail expression ability we are discussing.

It does not mean that pictures with large pixels will be good and not rough. Photo quality has little to do with pixels.

The quality depends on the lens CCD and the compression rate of the color management system output. Wait
