Panasonic AG-HPX255 Bit Digital Signal Processor, Dynamic Range Stretch DRS, Five User Buttons

20 bit Digital Signal Processor

The AG-HPX255/HPX250 incorporate a high-performance 20 bit DSP that handles image rendering processes such as gamma and various detail enhancement functions with exceptional precision.

DSP Processor

Dynamic Range Stretch (DRS)

In scenes with mixed contrast, such as when panning from indoors to outdoors, the DRS function automatically suppresses blocked shadows and blown highlights. A gamma curve and knee slope are estimated to match the contrast of each pixel, and applied in real time. When dark, bright, and intermediate shades are all contained in the same scene, this produces excellent gradation for each shade and minimizes blocked shadows and blown highlights.

* The DRS function does not operate in 1080/24p, 1080/25p or 1080/30p mode.

Seven Mode Gamma for Richer Gradation

Drawing on technologies developed for the VariCam, Panasonic has equipped the AG-HPX255/HPX250 with advanced gamma functions that address seven different shooting scenarios, including two Cine-Like Gammas.
