Resolution explains, what is called resolution

The precision of the screen imageResolution refers to the precision of the screen image and indicates how many pixels the display can display.

Because the dots, lines, and surfaces on the screen are made up of pixels, the more pixels a display can display, the more detailed the picture will be, and the more information can be displayed in the same screen area, so resolution is one of the most important performance indicators.

Resolution determines how detailed a bitmap image is, and in general, the higher the resolution of an image, the more pixels it contains, the sharper the image, and the better the quality of the print.

Resolution (resalution) is the precision of the screen image, which refers to the number of dots that the display can display. Since the dots, lines, and surfaces on the screen are composed of points, the more dots the display can display, the more detailed the picture will be, and the more information can be displayed in the same screen area, so resolution is one of the most important performance indicators. Think of the image as a large chessboard, and the resolution is expressed as the number of intersections of all the meridian and latitude lines.

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 the point distance of the picture tube and the bandwidth, among which, it is closely related to the refresh rate.

According to the number of horizontal and vertical pixels, it can be divided into: 320 200, 640 480, 800 600, 1024 768, 1280 1024, 1600 1200 and so on. Generally speaking, the recommended resolution is 1024 768 for a 17-inch CRT monitor and 1280 1024 for a 19-inch CRT monitor.

For CRT displays, the more and larger the resolution it supports, the wider its range of applications, and the higher it will be.

60 inches and 37, if the resolution is 1366*768, the pixels are the same, the difference is the point distance, that is, the distance between each pixel size, 60 and 37, if the same text file is displayed, the most intuitive, 60 words are much larger than 37.

The LCD display (general screen) of 17 and 19 is 1280*1024

The word 19 is much larger and looks more comfortable, and the word 17 is much smaller.

Screen Resolution: The resolution at which the screen is displayed.

Resolution refers to the precision of the screen image and indicates how many pixels the display can display. Because the dots, lines and surfaces on the screen are composed of pixels, the more pixels the display can display, the more detailed the picture, and the more information sources can be displayed in the same screen area, so resolution is one of the most important performance indicators.

Hail resolution determines how fine the bitmap image details are, and 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.

Resolution, also known as resolution and resolution, is a parameter that measures the amount of data in a bitmap image. It is usually expressed as pixels per inch (ppi) and dots per inch (dpi).

Resolution can be subdivided into display resolution, image resolution, print resolution, and scan resolution, among others.

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.

1. PPI: Image resolution refers to the amount of information stored in an image. There are several ways to measure this resolution, typically measured in pixels per inch (ppi).

2. PPD (pixels per degree): angular resolution or spatial resolution, which refers to the number of pixels filled in the field of view angle on average per 1° angle.

3. SPI: Scanning resolution refers to the resolution set before scanning an image, which affects the quality and performance of the generated image file, and determines the way the image will be displayed or printed.

4. LPI: Screen resolution, also known as screen frequency (is a printing term), refers to the number of network cables per inch of the screen used for printing images (that is, the number of network cables hanging on the screen), which is expressed in (LPI).

5. DPI: Device resolution, also known as output resolution, refers to the number of points that can be generated per inch on various output devices, such as the resolution of monitors, inkjet printers, laser printers, and plotters.

6. Bit resolution: The bit resolution of the image, also known as bit depth, is used to measure the number of bits of information stored in each pixel. This resolution determines the likelihood of how many color levels can be labeled.

Common colors are 8-bit, 16-bit, 24-bit, or 32-bit colors. Sometimes we also refer to bit resolution as color depth.

Resolution is the display resolution vs. the image resolution.

Resolution, also known as resolution and resolution, can be subdivided into display resolution, image resolution, printing resolution and scanning resolution. Resolution determines how detailed a bitmap image is. In general, the higher the resolution of the image, the more pixels it contains, the clearer the image, and the better the quality of the lead scrambling brush.

At the same time, it also increases the storage space taken up by the files.

The units that describe resolution are: DPI (dots per inch), LPI (lines per inch), PPI (pixels per inch), and PPD (pixels per degree). But only LPI is a scale that describes optical resolution.

Although DPI and PPI are also units in the category of resolution, they have different meanings than LPI. Moreover, LPI and DPI cannot be converted, and can only be estimated empirically.

Evaluation of resolution

1. It is only suitable for large aberration systems. The resolution of an optical system is directly related to its aberration size, i.e., aberration can reduce the resolution of an optical system, but in small aberration optical systems (e.g., telescopic systems, microscopic objectives), the actual resolution is almost exclusively related to the relative aperture (diffraction phenomenon) of the system, and is very little affected by aberrations. In large aberration optical systems (such as photographic objectives and projection objectives), resolution is related to the aberration of the system, and resolution is often used as the imaging quality index of the system.

2. There is a difference between it and reality. Since the discrimination plate used for resolution detection is black and white stripes, this is very different from the brightness background of the actual object; In addition, the resolution of the same optical system is measured by using the same discrimination plate, and the results are different depending on the lighting conditions and the receiver.

3. It has a pseudo-discrimination phenomenon. When the resolution is detected by the control phase objective, when a certain group of stripes of the discrimination plate can no longer be distinguished, but a denser group of stripes can be distinguished, which is caused by the contrast inversion.
