Cameras
The main camera module is a EDOF 3.2Mpix. The secondary camera is for video calls. Both cameras are
connected directly to the baseband, no hardware accelerator is used. Processing of the image is done by
phone processor using NIPS (Nokia Imaging Perfection System) algorithms.
The CCI-bus (Camera Command Interface) is an I2C-compatible interface that is used bidirectional to transfer
commands from BB to the camera and to get information of the camera register settings from the camera
to BB.
The CCP-bus (Compact Camera Port) is a unidirectional interface that is used to transfer the image data from
the camera to BB. It is a high speed differential interface. Both cameras are equipped with CCP class2 interface,
i.e. up to 650 Mbit/s. The device baseband supports CCP class0 (specified up to 208 MHz) and CCP2 (specified
up to 650 MHz). The main camera is connected to the CCP2 and the 2nd camera to the CCP class0 intferface.

Camera flash
The device has one flash LED located next to the camera on a separate small PWB.
The flash LED is controlled by the flash LED driver (D5900) that is located on the engine PWB. The flash PWB
is connected by two pogo-pins to the engine PWB.
