I believe many friends have heard the word 4K camera and know that the camera they use supports 4K photography. I want to ask you a question. Do you know that 4K is a multi megapixel camera? If not, I suggest you read this article
The standard of 4K is different. If the 4K of "UHDTV standard" is used for conversion, the pixel of 4K camera is up to 8.2844 million; If it is the "Academy 4K standard", its pixels are up to 9739600 (about equal to); If it is the "Full Aperture 4K standard", its pixels are up to 12.7447 million (about equal to). Therefore, if you want to judge whether a 4K camera is a megapixel, it depends on what the 4K standard is.
How to determine the 4K standard?
There is no uniform 4K standard in the industry, but based on different brands and hardware manufacturers, devices or images with a horizontal resolution close to, equal to or greater than 4096 pixels are called 4K in the industry, such as several standards mentioned above, such as 3656, 3840, 4096 (horizontal pixel value), etc. Taking the display as an example, the size of the display can be divided into width and height. As long as the wide display conforms to the pixel value mentioned above, it can be determined that the display conforms to a certain 4K standard, as well as the camera. The video or picture horizontal pixels generated by shooting or taking pictures are close to, equal to or more than 4096, which belongs to 4K.
No matter which standard 4K camera is used, its pixel difference is not as big as expected. As long as the camera is marked with 4K, its resolution will generally be between 8 million and 13 million, depending on which standard the camera is used.
