• Mobile applications

requiring a mega-

5 Megapixel Camera Interface

or video input

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

• Image scaling of

main and self

picture

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.

on-the-fly

MARVIN-5MP represents a complete video and

still picture input unit. It contains image process-

ing (ISP), scaling and JPEG compression func-

tions. For displaying on LCD the

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

*MARVIN-5MP was formerly part

of the sci-worx GmbH product

portfolio. Silicon Image acquired

sci-worx in January 2007.

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.
