Mobile phone What is a 4k camera?

What does 4k mean for mobile phone cameras?

K stands for thousands.

4k means that the camera pixel of this mobile phone has reached 40 million (generally omitted), so it should be a very good mobile phone.

A 4k camera refers to a camera whose recording picture resolution can reach the 4K standard, which is commonly referred to as an ultra-high definition video recording camera. In the generated video file, the maximum single-sided pixel can reach more than 4000 pixels. For example, the pmw-f5 and F55 used by Sony to shoot China on the Tip of the Tongue 2 have reached this level. Even now many mobile phones are advertising 4k, which is inaccurate. In the true sense, 4k refers to the image quality of the original image without enlargement, with the maximum pixel per inch.

What does a 4k camera mean?

Lead: The 4K camera adopts a brand-new hardware platform with higher performance and is equipped with 1200 Wan Chao high-definition image sensor, which has the characteristics of accurate and natural color reproduction and clean and delicate image quality. So what does a 4k camera mean? What's the quotation for a 4k camera? Let's take a look at it next.

What does a 4k camera mean?

A 4K camera refers to a resolution of 3840*2 160 and an aspect ratio of 16:9. Under this standard, CMOS progressive scanning can reach 2 160P. Compared with 2 million pixels, 4K HD network camera has higher vertical resolution, more accurate level of detail, clearer, cleaner and more immersive display effect, which can effectively meet the monitoring requirements of high-definition image quality and complex lighting places.

4K camera has many functions, such as region of interest coding, image stabilization, remote focusing and SDXC storage. Flexible code rate strategy also provides users with more code stream combinations, which are suitable for financial, telecommunications, government, schools, airports, factories, hotels, museums, traffic monitoring and other places that need high-definition image quality and complex lighting.

Regarding the application of 4K technology in the security field, some insiders said that although the 4K monitoring product line is still in its infancy, with the development of technology and user experience, it will definitely drive the development of other 4K related equipment and products in the security industry, such as matrices, controllers and hard disk video recorders. Therefore, the subsequent 4K monitoring products are likely to replace FHD monitoring as FHD monitoring replaces HD monitoring.

Obstacles to the Development of 4k Camera

The 4K camera is a system-wide project, and the matching lens must have a resolution of at least 8 million to give full play to the effect of the 4K camera. Network transmission bandwidth is higher: generally transmit 1080P high-definition code stream. As long as the bandwidth is 2M-4M, and the resolution of 4K is four times that of 1080P, the bandwidth of 6M-8M or even higher is required. Of course, the combination of 4K camera and H.265 coding will alleviate the transmission and storage pressure brought by the resolution improvement. Stronger back-end decoding ability: For back-end decoding equipment, processing 4K code stream requires stronger computing power.

Display devices with higher resolution: A display device must have at least 4K physical pixels in order to present 4K images without loss. Larger storage capacity: For storage devices, because the code rate of 4K code stream is larger, it needs larger storage capacity to store the code stream at the same time. Stronger intelligent processing capability: For the monitoring image with 4K resolution, there are more pixels in the image and more details are presented. For intelligent services based on video image processing, it provides more fidelity video processing images, and it also needs more computing power to deal with these richer details.
