Japan Broadcasting Corporation (NHK) has developed a large 133Mpixel CMOS image sensor capable of processing the millions of pixels required for each of the red (R), blue (B), green (G) colors of 8K video, in a single and compact element.

A single Super Hi-Vision (8K SHV) video frame consists of approximately 33 million pixels. The first 8K video cameras used three 33 MPixel image sensors in order to process the Red (R), Blue (B) and Green (G) color information, making the cameras more bulky.

NHK's new 133 Mpixel CMOS (15,360 x 8,640 pixels) is capable of processing the RGB information itself, allowing for the development of smaller, single-chip 8K cameras.

The new CMOS is capable of shooting 8K video a 60 FPS. Its light receiving surface is 43.2mm (diagonal), equivalent to 35mm full-frame.

I can see it now! We will get our new GH5 in 1016. It shoots 8k at 60fps. There are no 8k external recorders available. Everybody is asking: What can we do with our 8k footage? Answer: downrez to 1080 P24 Uuugh!

It has become clear that Japan is planning to launch an 8K SHV test broadcast and then promptly restructure the UHD service. Apple has also announced that they will release the ‘iMac 8K’ with a super-high resolution display later this year. Korea is also preparing to offer an 8K service demonstration at the 2018 Pyeongchang Winter Olympics. LG Display displayed a new beacon of the 8K era by revealing their 98-inch 8K Color Prime Ultra HDTV at CES 2015.

According to IHS, shipments of 8K (7680 by 4320 pixels) TVs are expected to increase from 2,700 shipped worldwide in 2015 to 911,000 in 2019.

Huh.

Innolux will begin mass producing 8K TV panels by the second quarter of 2016, according to company remarks at Touch Taiwan 2015.

The company displayed new 8K 65-inch TV panels at the Touch Taiwan exhibition running from August 26-28 in Taipei. The company said such technology in addition to 75-, 85- and 100-inch TV displays will go into mass production in second-quarter 2016.

Log reached 8K :-)

Sharp is expected to release 8K monitors aimed at the B2B segment in Japan by the end of October 2015 as part of its first step in commercializing the technology, according to Japan media.

Japan is moving toward 8K resolution as a national standard by 2020 and makers estimate that 8K could reach a penetration of 30% by 2018 in the TV segment. Pushing 8K monitors into the market would be a first step for gaining visibility in the 8K segment, and Sharp has already begun to see orders from major outlets such as NHK Television Network, the reports said.

The company's 8K monitors sized 85-inch will come equipped with IGZO display technology and be priced initially at around US$12,500-13,300. Sharp will first promote the technology in the medical segment, art museums and broadcasting units.

Japan Display Inc. ("JDI") has announced the development of the world's first 17.3-inch high resolution (7,680(W) x RGB x 4,320(H) pixels), fast response (frame rate 120Hz) liquid crystal display (LCD) module, the same size as the standard monitor commonly used for the video image production.

The LCD module, based on low temperature poly-silicon (LTPS) technology with true 8K pixels (RGB stripe arrangement), realizes high definition (510ppi) images, and the 120Hz frame rate enables smooth playback of moving image. By providing wide viewing angle, high contrast and little color shift, the advantages of IPS technology enable reproduction of life-like 8K image with a sense of depth in image quality.

It seems that lens resolution will be an issue for the 8k video. In the lenstip website they do measurements about lens resolution in line pairs per milimeter (lp/mm) and also with resolution charts.

The average resolution for a full frame lens is around 45-50lp/mm and a great m43 lens is around 77-82lp/mm. The resolution charts shows the lenses at around 2000 - 2600 lines resolution maximum in still photos. Using a full frame lens in m43 sensor is worse because the sensor magnify the center area so the lp/mm will be half compared to same lens in a FF camera, a focal reducer can help a lot.

So the still lenses can work good up to 4k resolution, sometimes lower resolution than 4k video, and maybe for 8k video there will be the need of new special lenses, high price.

Considering that the indie people can buy only low price lenses, so work with 8k video will not make sense. 4k video is the maximum resolution for our photo/still lenses, no matter they are m43, aps-c or ff lenses.

Example: the 12-35 lens at f4 is around 77lp/mm in the image center, the GH4 sensor in 4k is 8.1mm height, doing the maths this lens will resolve around 1250 lines in GH4 4k video.

The new full frame Sigma Art 20mm 1.4 can do around 47lp/mm, so it will resolve around 770 lines in GH4 4k video. With a focal reducer this can increase to around 1080 lines. Most good Full Frame lenses are around a 50lp/mm maximum, and this is stoped down to f5.6

In a full frame camera, considering the sensor 36 x 20,25mm, this same sigma lens can resolve around 1900 lines.

The RGB bayer pattern decreases the camera resolution a little bit, around 1,33x less than the pixel count, so a 2160p video will deliver a maximum 1620 lines. The GH2 is 1080p and is around 810 lines.

Lens resolution is a good reason for Panasonic release new cameras with the multi aspect sensor, a bigger sensor can use more image area form the lens and record higher resolution, more lp/mm. The GH4 sensor is 8.1mm height, 1250 lines with the 12-35 lens. The multiaspect sensor with 3840x2160 pixels for video would be 10,09mm height, and could record 1560 lines from the same lens.

All these maths shows that 4k video is the sweet spot resolution for a video camera and for the lenses we can buy, and all these maths are in image center, in corners the lenses resolution is worst.

Panasonic will once again develop image sensors after freezing such operations for the last few years, aiming for applications including 8K ultrahigh-definition technology.

Image sensors turn light into electronic signals, and are used in digital cameras, smartphones and other devices. CMOS (complementary metal-oxide semiconductor) sensors are a well-known type. Panasonic will spend around 10 billion yen ($80.8 million) to develop next-generation image sensors, with plans to release them in fiscal 2018.
