The IMX032CQR captures high-resolution,
high picture quality 9.29M-pixel still images
at 30 frame/s. It also supports both high-definition
and high-speed video imaging and
thus can capture a wide range of images, from
everyday scenes to brief instants too short for
the eye to see. Furthermore, it can capture all
these images with superb picture quality. It
provides a wide variety of readout modes to
implement these imaging operations. |

 High-Speed Performance: 9.29M
Pixels at 30 Frame/s |
|
The IMX032CQR adopts column-parallel
A/D conversion to achieve high-speed
performance. Also, the high-speed output
interface transmits 12-bit serial data at the
high speed of 480 Mbps and can output 8 pixels worth of data at the same time.
These techniques allow the IMX032CQR to
read out 9.29M-pixel images at 30 frame/s,
8.30M-pixel images at 40 frame/s, and, if
truly high speeds are desired, 100K-pixel
images at 1000 frame/s. |
| Sensor Unit Pixel Achieves both
Higher Pixel Counts and Higher
Picture Quality |
|
To achieve an even higher pixel count,
Sony developed a 1.75 μm unit pixel CMOS
sensor. When reducing the size of the pixel,
we introduced several condensing efficiency
improving technologies and achieved a
sensitivity of 2300e- (typical).
Sony introduced new process technologies
that reduce noise. These technologies
suppress both random noise and fixed pattern
noise and the sensor captures high signal-to-noise ratio images. The analog CDS and
digital CDS circuits built into each column
are another feature of column-parallel A/D
conversion. The reduction of pixel noise and
the differences between individual analog
circuits is another indispensable element for
achieving high picture quality. The adoption
of these technologies made it possible to
achieve signal-to-noise ratios as good or
better than those of CCD with the same unit
pixel size. (See figure 1.) |
A Variety of Readout Modes to
Respond to a Variety of Needs
|
|
The IMX032CQR allows the user to select
from a variety of drive modes to match the
actual usage, such as high-resolution still,
high-definition video, or high-speed video imaging. (See table 3.)
The IMX032CQR allows either 9.29M pixels
or 8.30M pixels to be selected as the readout
area. In addition to a mode that supports
12-bit data output at 20 frame/s for both the
9.29M-pixel and 8.30M-pixel resolutions,
there is also a mode that allows continuous
imaging at 30 frame/s with 10-bit data output.
The IMX032CQR also provides a horizontal
and vertical 2/2-line addition readout mode
that supports 1440 × 1080 high-definition
recording.
Additionally, the IMX032CQR also provides
modes that are mainly designed to support
high-speed imaging. It achieves 240 frame/s
in vertical 2/7 elimination mode and up to
1000 frame/s in vertical 2/15 elimination
mode. Thus the IMX032CQR can isolate
instants that previously could not be
captured.
Sony hopes that you will be able to
experience a new photographic world made
possible by Sony high-speed CMOS sensors,
which achieve both superb picture quality
and high-speed performance at the same
time. |

What sort of things would you photograph
if there were a digital camera that were
capable of both high-resolution and high-speed
imaging? I’d like to photograph
my daughter, who is constantly moving
around with her small baby steps. I hope
that you will create a high-resolution/high-speed camera that never misses a
photographic opportunity. |
