CAMERA INTERFACE
OVERVIEW
This specification defines the interface of camera. The CAMERA INTERFACE in S3C6400X (Fully Interactive
Mobile Camera interface 3.0) supports ITU R BT-601/656 YCbCr 8-bit standard. Maximum input size is
4096x4096 pixels. The CAMERA INTERFACE in S3C6400X consists of several functions.
T_patternMux is
the
test pattern generator. Test pattern generation can be used to calibration of input sync signals as HREF and
VSYNC.
CatchCam
is the capturing ITU signal and window cut. Video sync signals and pixel clock polarity can be
inverted in the camera interface side by using register setting.
Two scalers
exist. The one is the preview scaler,
which is dedicated to generate smaller size image for preview. The other one is the codec scaler, which is
dedicated to generate codec useful image.
Two Channel MSDMA(Memory Scaling DMA)
can read the memory
data for each scaling path.
Two Output DMAs exist. The one is the Preview DMA. The other one is the Codec
DMA.
Two DMA are dedicated to the YCbCr 4:2:2, YCbCr 4:2:0 and RGB output. The CAMERA INTERFACE in
S3C6400X has
image rotator (90’ clockwise)
and
image effect
. These features are very useful in folder type
cellular phone.
