8K resolution - online puzzles

8K resolution, or 8K UHD, is the current highest ultra high definition television (UHDTV) resolution in digital television and digital cinematography. 8K refers to the horizontal resolution of 7,680 pixels, forming the total image dimensions of (7680×4320), otherwise known as 4320p.

8K UHD has two times the horizontal and vertical resolution of the 4K UHD with four times as many pixels overall, or sixteen times as many pixels as Full HD.

High-resolution displays such as 8K allow for each pixel to be indistinguishable to the human eye when viewed at a typical distance from the screen. 8K resolution can also be used for the purpose of creating enhanced lower resolution videos through a combination of cropping techniques and/or with downsampling techniques used in video and film editing. Resolutions such as 8K allows filmmakers to shoot in a high resolution with a wide lens or at a further distance, in the case of potentially dangerous subjects (such as in wildlife documentaries), by being able to zoom and crop digitally in post-production. The technique involves taking a portion of the original 8K image and cropping it to match a smaller resolution such as the current industry standard for high- definition televisions (4K, 1080p, and 720p ).

8K display resolution is the successor to 4K resolution. TV manufacturers pushed to make 4K a new standard by 2017. The feasibility of a fast transition to this new standard is questionable in view of the absence of broadcasting resources.

As of 2015, few cameras had the capability to shoot video in 8K, with NHK being one of the only companies to have created a small broadcasting camera with an 8K image sensor.
