What is the difference between pixels and resolution, and what is the difference between pixels and

Resolution, which refers to the number of pixels contained in a unit length, is usually measured in pixels inches (ppi). For a screen with a resolution of 1024 768, that is, each horizontal line contains 1024 pixels, with a total of 768 lines, that is, the number of scanned columns is 1024 columns, and the number of rows is 768. Resolution is not only related to the display size, but also affected by factors such as CRT point spacing, bandwidth, etc.

Among them, it is closely related to the refresh rate, strictly speaking, only when the refresh rate is "flicker-free refresh rate", the highest resolution that the display can achieve, that is, the highest resolution of the display.

Pixel definition: A pixel refers to the basic coding of the basic primary pigment and its grayscale. It is composed of the letters of the words "picture" and "element", which is a unit used to calculate the digital image, just like the photographic photograph, the digital image also has a continuous shade of tone, if we zoom in on the image several times, we will find that these continuous tones are actually composed of many small square dots with similar colors, and these small square dots are the smallest unit of the image "pixel".

This smallest graphic unit can display what is usually a single dot of color on the screen. The higher the pixel, the richer the color palette and the more realistic the color is.

A pixel is the absolute number of points that make up an image on a display or display surface. [The pixel unit is px (pixel), which is not an absolute size, but a basic imaging unit, and the size of a unit is not the same on different devices.] The smaller the cell size, the more detailed the image.

If the same cell size, the more cells there are, the larger the image size. ]

Resolution is the number of pixels per unit length of a single sheet or display. [Resolution is the number of pixels per unit size, commonly used in DPI (dots per inch, commonly used in the printing industry) or PPI (pixels per inch, commonly used in display devices).] The higher the resolution, the more detailed the image.

Simply understood, the number of pixels imaging units, the resolution density.

For example, if a ** is composed of 100 100 image points, then the number of pixels of this ** is 10,000. However, if the side of this image is 1 inch long, then its resolution is 100 point inches, which is 100 dpi. If the side length of this ** is 2 inches, then the resolution of this ** is 50dpi.

The higher the resolution, the more detailed the display.

The ** resolution produced by early 300,000-pixel digital cameras was 640x480 = 307,200 300,000 pixels.

The pixel is equal to the resolution multiplied by the size, the higher the pixel is, the smaller the size, the higher the resolution, and the higher the resolution of the image, the clearer it looks.

Resolution and pixels are two different concepts, but they have a certain connection and correlation.

Pixel, or px, is the smallest dot on the screen. The size of a pixel is "variable", also known as "relative length". For digital**, each dot is called a pixel. A ** is composed of 300,000 color dots, and the pixel of this ** is 30W.

Usually it is said how many pixels the camera has, this pixel is how many sensors there are in the camera, a camera with 100w sensors is a 100w pixel camera, a camera with 4000w sensors is 4000w pixels, and so on.

Resolution = pixel value on the x-axis of the screen * pixel value on the y-axis. If the screen is 1024 768, that is, there are 1024 pixels in the horizontal direction and 768 pixels in the vertical direction.

1. Pixel refers to the number of points (indicating how many points ** is made of), and resolution refers to the density of pixels (it is the number of pixels in the unit size, generally expressed by the number of points per inch - dpi).

**Actual size is determined by pixels. A pixel is very large, and if the resolution is set to be large, the printed ** may not be large (but it is clear). Conversely, if you set the resolution to a very small resolution, the print may be large (but not sharp).

2. Resolution refers to the pixel value per unit length, which is related to the printing quality, and the general dimension used is ppi; The total pixel refers to the sample accuracy of **, which is related to the printable size, and is usually expressed in the way of "length and width", and the product is usually called the total pixel. Due to the different aspect ratios of **, the same total pixel can have multiple specifications.

The larger the pixels, the higher the resolution, the clearer the size, and the larger the output.

Resolution: The resolution determines how detailed the bitmap image is. In general, the higher the resolution of the image, the more pixels it contains, the sharper the image, and the better the quality of the print.

At the same time, it also increases the storage space taken up by the files. There is a direct relationship between resolution and pixels of an image.

Pixel: Pixels are the most important metric to measure a digital camera. Pixels refer to the resolution of a digital camera.

It is determined by the number of photosensitive elements on the photosensor in the camera, and one photosensitive element corresponds to one pixel. So the larger the pixels, the more photosensitive elements there are, and the higher the corresponding cost. The larger the pixels, the larger the resolution and the larger the printable size.

The higher the resolution, the higher the pixels, and if we magnify a computer image taken with a digital camera several times, we will find that the image is actually made up of many small square dots of similar color, which are the smallest units of the image, called pixels. The higher the pixels, the clearer the image, the more expressive the colors, and the more realistic the colors of the subject.

<> resolution refers to the number of pixels per unit area (per inch) and is usually measured in dpi (dots per inch). Generally speaking, the higher the pixel of the image for the same size image, the higher the resolution. A resolution of 150 to 200 dpi is sufficient for home use**, but for print or magazine use, at least 300 dpi is required.

Pixels and resolution can be said to be hard indicators of high digital quality and high definition. Only when the pixels are high enough can digital** show excellent clarity, depth and detail.

In practice, the principle is to divide the number of pixels on one side by 100 to get the output format in centimeters. For example, a 16 cm 12 cm 2 million pixel (1600 1200) image can provide very good quality for professional printing, but if you want to print a professional A4 size **, you need at least 12 million pixel resolution.

Pixels refer to the number of dots in a cell (how many dots a sheet consists of), while resolution refers to the density of pixels in a pixel (pixels per unit size, usually expressed as dots per inch - dpi). **The actual size is determined by pixels. If you shoot a lot of pixels, if you set the resolution to a lot of pixels, then the print won't be very big.

To put it simply, what we usually call pixels, is the number of photoelectric sensing elements on CCD CMOS, an image sensor through light sensitivity, photoelectric signal conversion, AD conversion and other steps, in the output of the ** to form a point, if we magnify the image several times, we will find that these continuous tones are actually composed of many small square points with similar colors, these small square points are the smallest unit of the image "pixel" (pixel). Pixels are divided into CCD pixels and effective pixels, and most of the digital cameras on the market today are marked with CCD pixels rather than effective pixels.

Pixels are the unit of resolution, if the width of a ** is 1280 pixels, and the height is 720 pixels, then its resolution is 1280x720, and the ratio is 16:9.

For example, the resolution of a ** is 1280x720, then the ratio of this ** is 1280:720 for approximation, that is, 16:9.

For example, the resolution of a ** is 800x600, then the ratio of this ** is 800:600 for approximation, that is, 4:3.

1. The units are different.

This is the resolution of the image set in Photoshop. This affects the printing effect of the image. Centimeters are metric units, inches are imperial units, and 1 inch = centimeter. 72 pixels inches = pixels centimeters.

2. The concept of use is different.

In the use of the real model, it is formulated according to the size unit used by the user. It doesn't make a difference when you don't need to print it. The more pixels per unit, the better the printing results, provided that the printer or printing machine can support a large resolution.

Pixels and resolution are two important concepts in digital images, and they play different roles in image quality and size.

Pixels areThe smallest unit that makes up an image, which records the details of the image, including the cracks such as color, brightness, and location. An image is made up of many pixels, and the higher the pixels, the better the source mask quality and clarity of the image. For example:

10000 pixels.

And the resolution isThe number of pixels rendered horizontally and vertically on the image。It reflects the level of detail of an image and is an important indicator of image quality. The higher the resolution, the better the quality of the image, but it also increases the file size of the image and the size of the printout.

For example: 1920*1080

In short, the pixels determine the imageThe level of detail is rich, and the resolution decidesThe sharpness of the image in both horizontal and vertical directions.

Hello, pixels and resolution are two inseparable important concepts, the way they are combined determines the amount of data in the image, the same size of the image, the higher the resolution, the more pixels it contains.

A one-inch square image contains 5,184 pixels at a resolution of 72 and 90,000 pixels at a resolution of 300. A high-resolution image contains more pixels than a lower-resolution image, so the pixels will be smaller and the density of pixels will be higher.

For example, most web pages commonly used in the production of ** resolution is 72, that is, each inch of pixels is 72, 1 inch is equal to centimeters, then through conversion, it can be concluded that each centimeter is equal to 28 pixels; Another example is the length of 15x15 cm, which is equal to the length of 420*420 pixels.

For example, in an 8-bit image, the maximum unsigned number is 255, so this is the white value. In a color image, each pixel can be represented by its hue, saturation, and brightness, but is usually represented by red, green, and blue intensity.
