What is the difference between 720P, 960P, 1080P, 4K? In this article, I will try to explain some basic terminology about resolution, hoping to help our readers understand camera resolution better.
First, the resolution of the camera
Usually refers to horizontal resolution, unless "vertical" is specified. The indicator for evaluating the resolution of a camera is the horizontal resolution, and its unit is a line pair, that is, it can be divided intoThe number of black and white line pairs that can be identified. Commonly used black-and-white cameras generally have resolutions of 380-600, and color resolutions of 330-540. The larger the value, the clearer the image.
2. Pixels
Pixels are an expression of camera resolution.But first of all, we need to understand that the pixels of the camera are divided into: static pixels and dynamic pixels.If a standard-definition camera is rated at 3 million pixels, it should be noted that what is said here is still image element, and cannot be used for photography. You need to look at the second parameter, 500,000 dynamic pixels,
This is the number of pixels available for shooting.
3. Resolution and pixels
Resolution includes both horizontal and vertical directions, and is an index of clarityGenerally sharpness and pixels are consistent.
For example, SD, you can multiply 720 by 576, and you can see what the result is. and nominal
The dynamic pixel values are very close. Pixels represent the camera's shooting capability, while resolution is the camera's recording capability. The two should be that the dynamic pixel value is greater than the definition.
4. Resolution format
The NT SC standard of the TV is 720x480 with a refresh rate of 6 0Hz, and the PAL is
720x576 with a refresh rate of 50Hz. my country's TV broadcasting uses the PAL system.
1080P is two million pixels, and the resolution reaches 1920*1080
720P is one million pixels, and the resolution reaches 960*720/1280*720
D1: Resolution 704*576 (equivalent to 4C IF)
FULL D1 resolution 704X576, 720X576,
Half D1 resolution 720x2884CIF: resolution 704*576
2CIF: Resolution 704*288(HALFD1) CIF: Resolution 352*288
QCIF: is quarter (quarter times) resolution 176*144
VGA: Resolution is 640*480
QVGA is qua rter (quarter times) resolution 320*240

The dynamic pixel values are very close.
The pixel represents the shooting ability of the camera, while the resolution is the recording ability of the camera
force. The two should be that the dynamic pixel value is greater than the definition.
