2M-Pixel CMOS Camera Module with Autofocus Function for Mobile Equipment
MCB770
Based on Sony’s experience introducing 1.3M-pixel CCD camera modules
to the marketplace, Sony has embarked on efforts to respond to
customer desires for increased pixel counts, improved functionality,
reduced power consumption, and further miniaturization and lower
mounting heights in CCD camera modules.
The MCB770 introduced here is a new product that responds to these
desires with newly-developed technologies such as a 2M-pixel CMOS
sensor and an AF function that can handle a wide range of camera to
subject distances.
This product adopts many ideas from the dedicated digital still camera,
which has acquired wide support in the image creation areas, to
achieve a balanced and rich set of image expression capabilities. |

High-Performance Lens with
Wide Distance Range AF
Function |
|
The MCB770 includes an AF system for
the first time in a Sony camera module
product. This AF system focuses over a
wide range of distances from 10 cm, a distance
selected specifically for imaging QR
codes, to infinity.
It also includes a focus
point prediction function to improve focusing
performance. In addition to an AF
control system that takes advantage of
Sony’s experience in dedicated digital still
cameras, it also adopts a linear method.
This made it possible to create a miniature
low-power AF system optimal for a
camera module. The MCB770 also supports
manual focus.
Sony achieved low TV distortion and high
resolution performance by combining a
lens design optimized in conjunction with
the sensor structure with a 3-element,
3-group glass lens. |

High Picture Quality CMOS
Sensor for Mobile Equipment |
|
The MCB770 includes the IMX011CQ*
diagonal 5.97 mm (Type 1/3.0) 2.13M
total pixels primary color progressive scan
CMOS sensor that was designed at the
same time as the MCB770. This device
was designed for use in mobile equipment
and achieves the high-speed progressive
scan of all pixels at 15 frames/s and the
same high picture quality as CCD sensors.
While it goes without saying that this device
uses Sony’s know-how developed
over many years of CCD development as
a foundation, this device also features further
optimization of the pixel layout and
on-chip microlenses.

Newly-Developed DSP for
Natural Image Rendition and
High-Generality Interface |
|
The MCB770 provides three formats: draft
mode, which is intended for preview moving
picture, uncompressed capture mode
for moving picture recording, and JPEG
capture mode for still images.
The
MCB770 supports flexible end product
design by providing a variety of image
sizes in each of these modes.
The MCB770 provides rich image expression
that will not betray our customers’
hopes for image creation.
The AE and
AWB algorithms implemented in the
newly-developed DSP are based on concepts
from dedicated digital still cameras
and take into account the functional
balance required in a camera module.
The
MCB770 thus provides imaging performance
in difficult conditions that is
equivalent to that of dedicated digital still
cameras.
Furthermore, the MCB770 provides
a scene selection function that can
set optimal condition for the camera module
simply by selecting a scene mode that
matches the scene being imaged. |

This newly-developed camera
module was made possible by the
persistence of each of the persons
in charge of the various components;
the lens, sensor, DSP,
mechanism, mounting, image
quality, and plant. Our idea was to
provide more freedom and more
fun to users, we wanted our users
to experience the pleasure of being
able to photograph the things
around them freely and easily. We
are committed to continuing to
develop products to the best of
our ability. |
