and cameras with 8K resolution have also been developed. Since digital cinema
services have started, the development of 4K cameras for digital cinema is pro-
gressing. For example, RED (RED Digital Cinema Camera Company) is manufac-
turing a 4K camera called RED ONE which is equipped with a CMOS sensor of
12 Mpixel and has the resolution of 4520x2540. DALSA Origin with 4096x2048
resolution (8 million pixels) has been developed by DALSA and the camera is
characterized with 16 bit/pixel of high gradation. On the other hand, Octavision
with 3840x2160 resolution (8 million pixels) has been developed by Olympus. A
CMOS 4K camera which has a frame rate of 60fps with the resolution of
3840x2160 has been announced by Victor. Furthermore, an 8K video camera with
7680x4320 resolution (33 million pixels) captured by a high speed CMOS sensor,
60fps and 12 bit/pixel has been also announced by the Japan Broadcasting Corpo-
ration (NHK).

5.2 Display
Flat panel TVs such as LCD and PDP have been progressing with larger screen
and higher resolution. These TVs corresponded to the spread of digital contents
including digital broadcasting. A screen size of the 40 inches has become popular
and support for full HD resolution which can display images from television
broadcasting is becoming typical.
