The setup and recording parameters that can be set via the On-Camera Controls are:
Operational Mode
This filed is used to select if the camera is to run in either Loop or Run/Stop Mode.
In the Loop Mode, the camera stores the recorded image data into the camera's DRAM buffer.
In this mode, the Phantom CineMag operates like any other Flash card, after a cine file is
recorded into the camera's DRAM frame buffer, you can manually save it into the CineMag
using the "Flash Memory" dialogue window which can be accessed in either the Setup and
Recording or ViewCine dialogue windows.
In Run/Stop Mode the image data is recorded, up to 450fps at HD resolution (2048 x 1080),
directly into the Phantom CineMag.
EI (Exposure Index)
An amount by which it is possible to over or underexpose a light sensitive material and, with
standard processing, still produce acceptable results. By referring to the exposure index in the
viewfinder and working in stops, you can fine tune your exposure.
PD (Pedestal)
Used to change the voltage level corresponding to black or to the maximum limit of black
peaks.
CR (Chroma)
Short for chrominance, is the attributes of a color, which include its hue (frequency) and
saturation (amount of black).
WB (White Balance)
This process is used to balance the active pixels of the image sensor to the overall color
temperature of the lighting. The user only needs to perform a white balance at the beginning of
the day or when a major change occurs in the lighting, such as going from indoors to
outdoors , or using a different setup with color gel on the lights.
BB (Black Balance)
This process is used to remove any inconsistencies between pixels that make up the active
pixel area of a camera's sensor. There are two common unwanted effects in all silicon sensors
that can seriously reduce the quality of the images recorded, they are:
Fixed Pattern Noise
Also known as spatial noise. It is the unwanted variation of the response of all pixels in
the image. It is expressed as an offset in volts or in Analog-to-Digital Conversion (ADC)
bits. It does not vary with time.
Photo Response Non-Uniformity
The fact that each individual photo diode or pixel has a different amplification factor or
gain. It is a different flavor of FPN (Fixed Pattern Noise).
Both unwanted sensor byproducts are corrected, electronically, when a black balance is
performed.
PA (Production Area)
The camera will highlight the production area specified by under exposing the area outside the
production area by 1-stop, and changing it to be monochrome. This production area can be
though as the area of the captured image that will be used in the final production.
