designators include:
MagInit
Indicates the Phantom CineMag has been detected either during camera power-up, or when
a Phantom CineMag has been inserted onto the camera.
MagScan
Indicates that the Phantom CineMag is running through it power-up, self-diagnostics
routines.
MagReady
Indicates that the Phantom CineMag has passed its power-up, self-diagnostics routines.
MagErase
Indicates that the Phantom CineMag has been instructed to erase its contents, and is
performing the erasure procedure.
Number of Takes
This field indicates the number of takes or cine files, (movies), recorded to the Phantom CineMag.
As takes are recorded the Number of Takes field increments.
Memory Usage
This field indicates the amount of bytes used to store recorded frames. As takes are recorded the
Memory Usage field increments.
Memory Size
This field indicates the total number of bytes, or the memory size, of the Phantom CineMag.
Resolution
This field indicates the active pixel area, (Width x Height), of the sensor defined by the user.
Sample Rate
This field specifies the rate the Phantom camera will capture or record image data, (frames), into
the camera's memory.
Shutter Angle
This field shows the current, user defined, Shutter Angle or exposure setting of the camera.
Memory Buffer Graphical Representation
The graphical representation of the camera's memory buffer, which acts as a memory gauge will
display a Recording to Memory Location Indicator, (an up-arrow), that will scroll backwards from
the trigger point, (T), indicating that the memory buffer is in the process of being filled the moment
the camera has been placed into the LIVE WTR mode.
When the indicator reaches the beginning of the line the camera's memory buffer is full. This
does not mean that the camera stops recording since the camera utilizes a scrolling buffer
technique to fill the buffer. What this means is that the camera writes the captured image data or
frame into the first available memory location, the second frame into the second available
memory location, and so on until all available memory locations have been written into with image
data or frames. Once all the memory locations have been written into the next frame that is
captured will overwrite the image data that is presently stored in that first memory location, the
next frame overwrites the next location and so on. This process of overwriting memory locations
will continue until a trigger signal has been detected by the camera and any user defined post
trigger frame requirements have been recorded. It is only at this point the camera will stop
overwriting the captured images or frame stored in the memory buffer.
