MARVIN-5MP
5 Megapixel Camera Interface
The 5 Megapixel Camera Interface DesignObject™ (MARVIN-5MP*) is a complete video
and still picture input unit which is targeted on SoCs with image capture capability as
used in mobile phones with integrated cameras. MARVIN-5MP contains image process-
ing, scaling and compression functions. The integrated image processing functions allow
simple CMOS sensors without any image preprocessing to be supported as well as sen-
sors with integrated YCbCr processing.

improvement
Scaling is used for downsizing the sensor data in
order to display an image on a connected LCD,
or for generating a YCbCr 4:2:0 data stream for
video compression. Output data is transmitted
via an AHB interface. All functional blocks can
be configured using an on-chip microprocessor
via an AHB slave interface.
data to be stored. Besides using the parallel cam-
era interface, camera sensors can be connected
through serial interfaces according to the MIPI
or SMIA standard. MARVIN-5MP can easily be
adapted to lower or higher image resolution, e.g.
for saving gate count or memory.
MARVIN-5MP represents a complete video and

The scalers can handle up- and downscaling as
well as format conversions of YCbCr formats.
True Digital Zoom is supported in a two step
approach, where the image in the first step is
written to system memory and in the second
step is read back from system memory and up-
scaled. All data is transmitted via the AHB mas-
ter interface into system memory. The memory
locations are programmable depending on the
still picture input unit. It contains image process-
ing (ISP), scaling and JPEG compression func-
tions. For displaying on LCD the
MARVIN-5MP also includes a function to con-
vert YCbCr back to display-ready RGB format.
In this case the input format has to be YCbCr
4:2:2. In addition, the display-ready RGB data
can be rotated in 90° steps.
*MARVIN-5MP was formerly part
of the sci-worx GmbH product
portfolio. Silicon Image acquired
sci-worx in January 2007.
