|
The Image Sensor Controller (ISC) device provides the video input capabilities for the
|
||
|
|
Atmel/Microchip AT91 SAMA family of devices.
|
||
|
|
|
||
|
|
The ISC has a single parallel input that supports RAW Bayer, RGB or YUV video,
|
||
|
|
with both external synchronization and BT.656 synchronization for the latter.
