* "Exmor R" is a trademark of Sony Corporation.
The "Exmor R" is a Sony's CMOS image
sensor with significantly enhanced imaging
characteristics including sensitivity and low
noise by changing fundamental structure of
"Exmor" pixel adopted column-parallel A/D
converter to back-illuminated type.

 Vast Improvement in Picture Quality |
|
Compared to the current products, a Type
1/2.3 back-illuminated image sensor, the
IMX144CQJ is a Type 1/1.7 back-illuminated
image sensor that provides higher sensitivity,
higher dynamic range and lower noise.
Larger pixel size for improved sensor
characteristics and full use of Sony's unique
fine pixel processing technology mean that the
new image sensor has 1.3 times the sensitivity and 1.9 times the saturation signal level of
the current Sony product, IMX078CQK
(1.55 µm unit pixel, Type 1/2.3, approx.
12.40M-effective pixels, see the New Products
section in CX-NEWS, Volume 63). (See table
2.) Dark signal characteristics equivalent
to the current Sony products ensure high
picture quality from dark to bright areas. (See
photograph 1.)
This image sensor possesses characteristics
ideal for high-quality compact digital still
cameras and camcorders where high picture
quality is essential.

| Greater Optical Design Freedom |
|
Larger pixel size combined with better
light collecting characteristics have vastly
increased incident light angle characteristics
(see figure 1) and yielded more favorable
f-number dependence over the current Type
1/2.3 back-illuminated image sensors.
Thanks to these improvements, the new image
sensor offers greater optical design freedom
and can cope with brighter lenses and high
power zoom lenses. |
| 4K and Many Other Shooting Modes |
|
Sony's unique high-speed scanning
technology has allowed us to build a variety
of drive modes. (See table 3.) The Type 1/1.9,
approx. 9.03M-pixel (approx. 17:9) sensor
enables high-definition and high-speed
video recording of 4K 60 frame/s makes this consumer image sensor capable of the nextgeneration
4K format. Also, the image sensor
comes not only with full HD at 60 frame/s
(mode 1) but is capable of slow-motion
shooting with HD at 240 frame/s (mode 4)
and has plenty of other video functions. |
| High Speed and Low Power
Consumption |
|
While the image sensor ensures high picture
quality and high speed, the structure of the
column-parallel A/D conversion circuit was
reconfigured to reduce power consumption
by about 34% compared to the current Sony
products. (Mode 1: full HD 60 frame/s mode,
see table 2.)
In addition to increasing the number of
images that can be shot, these achievements
have added value by greater versatility and
low-power design. |

In the general trend towards ever higher
pixel counts and fine pixel processing,
our goal behind the development of
the IMX144CQJ was to also design in
"excellent picture quality in a compact
size." Large pixel size and taking cutting-edge
back-illuminated and fine pixel
processing technology to the next level
have significantly improved picture quality.
We strongly recommend that you
look into Sony's high-speed and high-sensitivity
imaging technologies for your
next camera. |
