 High Sensitivity and Signal-to-Noise
Ratio Characteristics |
|
Responding to the desires for Type 1/4 1.43M effective
pixel (SXGA resolution) high-sensitivity
CMOS image sensors for industrial
applications, Sony has now developed the
IMX076LQZ/CQZ devices that are based on
a 2.8 µm diagonal pixel.
In particular, these devices achieve the high
sensitivity required for industrial applications
through improvements to the pixel process
technology and design of pixel conditions
and layout optimized for the 2.8 µm diagonal
pixel.
Furthermore, these devices minimize both
random and fixed pattern noise and assure a
high saturation signal level. Peripheral circuits were also designed to reduce noise, support
low supply voltage operation, and to achieve
a low signal-to-noise ratio and an expanded
dynamic range.
As a result of these improvements, Sony was
able to acquire, in a Type 1/4 small-pixel
(2.8 µm diagonal) image sensor, sensitivity
and signal-to-noise ratio characteristics
equivalent to the Sony's existing Type 1/3
1.39M-effective pixel CMOS image sensors.
These new image sensors provide high picture
quality even in low ambient light levels
and allow imaging with a higher gain. (See

| Extensive Set of Drive Modes,
Including HD |
|
In addition to all-pixel scan mode, the
IMX076LQZ/CQZ also support 720p HD
mode, window cropping mode, and other
drive modes. These devices also provide
switching between 10 and 12-bit A/D
conversion modes, in particular providing
30 frame/s imaging in 12-bit A/D conversion
mode and 30 and 60 frame/s imaging in 10-bit
A/D conversion mode. Furthermore, they
provide 120 frame/s imaging in VGA size
window cropping mode.
These image sensors also provide a wide
range of other functions to support industrial
applications. |
Serial Output Interface
|
|
In addition to the CMOS parallel output
interface provided by existing products, these
devices also provide a low-voltage 1 or 2-port LVDS serial output function that users can
select according to their usage conditions. |
Easy-to-Mount LCC Package
|
|
The IMX076LQZ/CQZ are provided in
a reduced-pin-count 50-pin LCC package
that only has pins around its periphery. This
package contributes to reduced burden on
our customers' mounting processes and
furthermore supports high-temperature
reflow soldering with a peak temperature
of 240 °C. |
Lineup
|
|
In addition to the long exit pupil distance
IMX076LQZ, Sony has also at the same
time developed the short exit pupil distance
IMX076CQZ. The IMX076CQZ is appropriate
for use in modules and other applications that
use a wide lens, thus allowing customers to
choose a product that matches their needs. |
