1.1 Technology
The camera head uses three 2/3-inch CCD sensors. It is available with DPM, FT, IT or
ITW type sensors. A range of adapters can be connected to the head making a flexible
camera system that is equally at home in the studio or out on location in an OB
environment.
1.1.1 Frame Transfer DPM sensor
The Frame Transfer CCD DPM sensor offers superior performance and can handle
highlights of up to 600%. The 2/3-inch sensors have a high dynamic range and high
linear sensitivity over all camera lens apertures. Frame Transfer technology ensures that
there is no lag nor smear. The Frame Transfer DPM sensor uses Dynamic Pixel
Management which allows the format of the sensors to be switched between 4:3 and
16:9 aspect ratios at the touch of a switch without loss of horizontal or vertical
resolution. The 1000 pixels per line in both formats ensures that there is no loss in the
horizontal viewing angle but also ensures high resolution in the red, green and blue
channels.
