8K resolution, or 8K UHD, is the current highest ultra high definition television (UHDTV) resolution in digital television, computer graphics 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.

4. 8K resolution, or 8K UHD, is the current highest
ultra high definition television (UHDTV) resolution
in digital television, Computer Graphics and
digital cinematography. 8K display resolution is
the successor to 4K resolution. This seminar
covers about 8k resolution and 8k camera
systems.
Introduction

5. What is resolution ?
+ The image on your computer screen is built up from thousands
or millions of pixels.
+ The screen creates the image you see by changing the colours of
these tiny square elements.
+ The screen resolution tells you how many pixels your screen can
display horizontally and vertically. It's written in the form 1024 x
768. In this example, the screen can show 1,024 pixels horizontally,
and 768 vertically.

6. What is pixel ?
In digital imaging, a pixel or picture element is the smallest
addressable element in an all points addressable display device.
So it is the smallest controllable element of a picture represented
on the screen. The address of a pixel corresponds to its physical
coordinates.

7. Pixel Density
PIXEL DENSITY-Number of pixels in certain space. Usually
measured in PPI.
PPI(Pixel Per Inch)-Number of pixel per inch.

8. Pixel Densities
1920 * 1080 pixels referred to as 2k.
4096 * 2160 pixels referred to as 4k.
7680 * 4320 pixels referred to as 8k.

9. IPHONE-
TOTAL PIXEL=700,000 PIXELS
PPI=326 PIXEL PER INCH
Comparison
HDTV-
TOTAL PIXELS=2,000,000 PIXELS
PPI=102 PIXEL PER INCH

10. Future of high resolution ?
Today's viewers watch a variety of video content on a
number of devices. With the proliferation of mobile
technologies, consumers continue to push the
boundaries for that content, specifically for video
quality. The recent introduction of 4K tablet computers
,an iMac computer with a 5K Retina display and Dell
Ultra Sharp 32 Ultra HD 8K monitor is an indication of
the interest in high-resolution images, even in smaller
screen environments.

14. + 8K resolution (7680 x 4320, 4320p), the successor of 4K resolution,
is now the highest UHDTV (ultra high definition) resolution in digital
resolution and film restoration/mastering and is 16 times detailed
than current 1080p resolution.
+ 4K is speculated to become a mainstream standard in resolutions
by 2017 and NHK plans to apply 8K to Japan TV broadcasting in
2020, especially in the 2020 Tokyo Olympics.

15. Cont…
+ 8K refers to the horizontal resolution of these formats,
which all are on the order of 8,000 pixels, forming the total
image dimensions (7680×4320).
+ 8K is a display resolution that may eventually be the
successor to 4K resolution.
+ 1080p is the current mainstream HD standard, with TV
manufacturers pushing for 4K to become a new standard by
2017,although the feasibility of such a fast transition as well
as the practical necessity of a new standard is questionable.

17. Cont…
+ One advantage of high-resolution displays such as 8K is to have
each pixel be indistinguishable from another to the human eye from a
much closer distance.
+ On an 8K screen sized 52 inches, this effect would be achieved in a
distance of 50.8 cm (20 inches) from the screen, and on a 92 in
screen at 91.44 cm (3 feet) away.
+ 8K FUHD has four times the horizontal and vertical resolution of the
1080p HDTV format, with sixteen times as many pixels overall. 8K
FUHD has four times the horizontal and vertical resolution of the
1080p HDTV format, with sixteen times as many pixels overall.

18. Cont…
+ Another practical purpose of this resolution is in
combination with a cropping technique used in film editing.
+ This allows filmmakers to film in a high resolution such as
8K, with a wide lens, or at a farther distance from a potentially
dangerous subject, intending to zoom and crop digitally in
post-production, a portion of the original image to match a
smaller resolution such as the current industry standard for
High-definition resolutions (1080p, 720p & 480p).

19. Cont…
+ Few video cameras have the capability to film in 8K, with NHK being
one of the only companies to have created a small broadcasting
camera with an 8K image sensor.
+ Sony and Red Digital Cinema Camera Company are both working to
bring larger 8K sensors in more of their cameras in the coming years.
+ Although 8K will not be a mainstream resolution anytime soon, a
major reason filmmakers are pushing for 8K cameras is to get better
4K footage.

20. Down Sampling
Through a process called down sampling, using
a higher resolution 8K image down sampled to
4K could create a sharper picture with richer
colours than a 4K camera would be able to
achieve on its own with a lower resolution
sensor.

21. VILLAIN
The First Indian Film Shoot In 8K Resolution Camera
This Film Uses ‘Red’ camera of ‘Weapon Helium 8K’ Series To Shoot The
Stylish Thriller.
This film will be down sample to 4k and 2k depending on theaters.

22. 8K Format
8K is a new resolution standard designed for digital cinema and computer
graphics. It has following advantages:
1. Higher image definition quality.
2. More detailed picture.
3. Better fast-action.
4. Larger projection surface visibility.
+ 8K format was named because it has 4000 pixels horizontal
resolution approximately.
+ Meanwhile, standard 1080p and 720p resolutions were named
because of its vertical resolution.

23. 8K Imaging system
+ Developed for use in next generation TV broadcasting systems.
+ Two methods of 8k camera systems :
a) Four Sensor Imaging Method .
b) Three 33-MPIXEL image sensors.

24. Four Sensor imaging Method
+ Meets the practical demands for the prototype camera systems.
+ To obtain high resolution and high quality pictures uses:
1.two image sensors for sensing green light .
2.one sensor for red light.
3.one for blue light.

25. Three 33-MPIXEL CMOS Image Sensor
+ Consumes relatively more power.
+ Has a high volume of signal processing devices.
+ Configuration is divided into the camera head and CCU(camera
control unit).
+ The camera head has:
1. image sensors.
2. head boards for driving the sensors.
3. a signal transmission interface for transmitting data to the CPU.

44. Conclusion
Display and resolution technologies are developing
day to day. The display technologies are now entering into
8k resolution technologies. This technology is more
advantageous in security systems and broadcasting.
More over the higher pixel density can be
use in biological and medical field. This advantages make
now 8k resolution more acceptable, but the cost is an
issue.
