Megapixel Class 1.28M-Pixel Diagonal 5.6 mm (Type 1/3.2)
Primary Color Progressive Scan CMOS Sensor for Cellular Phones
IMX006FQ
As the use of camera cellular phones becomes more widespread, the
shift to megapixel class camera cellular phones is accelerating.
Sony has now developed the IMX006FQ diagonal 5.6 mm (Type 1/3.2)
1.28M-effective pixel primary color progressive scan CMOS sensor.
At the same time as including a 10-bit A/D converter and achieving a 15
frames/s frame rate when reading out 1.28M-pixel images, that is, providing
the functionality and speed typical of CMOS sensors, the
IMX006FQ also incorporates Sony’s high picture quality technologies
developed for CCD, and thus achieves picture quality equal
or better than that of CCD. |

The IMX006FQ is a diagonal 5.6 mm
(Type 1/3.2) 1.28M-effective pixel
CMOS sensor that was developed
for use in cellular phone camera modules.
By adopting the Sony’s unique device structure to
provide pixel miniaturization and higher
picture quality, two issues that are
problematic in CMOS sensors,
Sony achieved miniaturization and improved
picture quality equivalent to those
of progressive scan CCD.
Furthermore, since CMOS sensors
have no smear, the IMX006FQ acquires
bright and clear images. Table 1 lists the
IMX006FQ device structure and table 2
lists its imaging characteristics. |

Improved Picture Quality |
|
In the IMX006FQ, Sony achieved sensitivity
that is no way inferior to that of CCD
by optimizing the on-chip
microlenses and photodiodes. (See photo-graph
1.) |
|
Built-in A/D Converter |
|
The IMX006FQ integrates a 10-bit A/D
converter, sensor control circuits, and other
circuits on the same chip. At the same time
as significantly reducing the number of
external components, integrating the A/D
converter on the same chip obviates the
need for analog signal processing that
requires fine adjustments and thus achieves
excellent picture quality. |
|
Low Power Consumption |
|
Despite providing 1.28M pixels at a 15
frames/s frame rate, the IMX006FQ
achieves the low power of under 80 mW. |
|
Module |
|
Sony provides the IU006 lens module,
which combines a lens with the
IMX006FQ. By combining a lens optimal
for the IMX006FQ, the IU006 achieves a
miniature form factor, high resolution, and
low shading. |
|
Increased Pixel Counts |
|
To achieve even higher pixel counts, Sony
is now developing the IMX011CQ CMOS
sensor with 2.07M effective pixels
and the IU011 lens module. |

We developed this sensor with the
hope that it would allow people to capture memorable moments with
their cellular phones and other portable electronic equipment that
adopts this sensor. Since it would be unfortunate to harm these
important memories, we put a lot of effort into picture quality, and
created a sensor that is in no way inferior to CCD. I hope that
this device will represent the start
of the CMOS sensor age. |
