3. Basic Operation and Features
The Unibrain cameras employ a progressive scan CCD sensor which provides different features for each model.
Basic functions and features are similar, while each camera has its own specific function support. The cameras-
fully support the IIDC V1.31 specification with regards to registers, video format, mode of operation and control.

setting of the camera and control them using the status control register. Adjust the brightness if the appropriate
gradation cannot be obtained due to blurring of black portions of the image. The parameters of Brightness are
changed inside the camera. For brightness, the parameters are shifted by the black level.
