What do camera pixels mean?

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 to view web pages

An 800,000-pixel digital camera can take the picture

The length is 1024 and the height is 768 (resolution ) pictures (meaning that an 80-megapixel digital camera photo can fill the screen on your monitor.

A 3-megapixel digital camera can take photos

Length 2048 Height 1536 (resolution ratio) photos. You have to drag the scroll bar to browse various parts 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 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

< p>The photos taken by a 2-megapixel camera are generally larger in size (viewed on a monitor)

The photos taken by a 3-megapixel camera are generally larger in size (viewed on a monitor)

The photos taken by a 5-megapixel camera (viewed on a monitor) are extremely large

The photos taken by a 10-megapixel camera (viewed on a monitor) are extremely large

Meaning That's it

The maximum size (pixels) you can take with a 2-megapixel digital camera 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. It can be said that this picture is a 3-megapixel picture (this is called software interpolation)

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

For example, Fujifilm's camera Many of them are interpolated from 3 million 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 when buying a digital camera, you must check the photo quality of the camera you want to buy.

It is not feasible to just look at pixels blindly.

As long as the image is taken by an 800,000-pixel digital camera, there is software that can enlarge it to 10 million or 20 million. 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 performance we are talking about.

It does not mean that pictures with large pixels will be poor. Good but not rough, photo quality has little to do with pixels

Quality depends on

lens

CCD

and color management System

The output compression rate

etc.

What you see in the image processing software on your computer is displayed in pixels, such as on your screen When the resolution is 800*600, your picture will be larger than when it is 1024*768. This is the reason.

To display the actual size of the picture, there is an easy way to insert it into a Microsoft word document without shrinking the size. Because Word is WYSIWYG, the size of the picture can be compared with the horizontal and vertical rulers. In addition, the size of the A4 paper is known, and the relative size of the picture can also be known.

The third question, pixel, is actually a concept of area. The situation mentioned by the original poster seems to be a problem of deformation in theory. The solution can be solved by setting the aspect ratio of the screen resolution to adapt to this picture. For audio and video files, there seems to be a player that can automatically adjust the pixels of the file to fit the display, or cut the edges, or add black borders. Some pictures have different width and height resolutions

Then the pixel grid of this picture is rectangular

But the computer display seems to default to a square pixel grid

So this Will the picture be deformed when displayed on the computer?

Will not deform.

The resolution of the picture is the same, only the distribution of pixels is different, that is, there are more and less square pixels in a picture (larger and smaller resolution). You can enlarge the picture to see whether the pixels are deformed. See The deformed picture still shows the relationship between the distribution and position of the pixels.

Does the computer not display the true size of the picture at 100% scale, but the pixel size?

So if two pictures with the same actual size but different resolutions are printed out

Are they the same size?

Opposite! The printed sizes are the same, but the clarity is different.
