Dynamic Range Stretch (Drs); 7-Mode Gamma For Richer Gradation; Ag-Hpx171 Gamma Modes; Advanced Image Adjustments Built-In - Panasonic P2HD AG-HPX171 Manual

DSP with 14 Bit A/D Conversion and 19 Bit Processing
The digital signal processor
developed for the
AG-HPX171's video signals
uses 14 bit A/D conversion and
19 bit inner processing to attain
unprecedented accuracy.
The DSP performs a variety of
adjustments, including seven
types of gamma settings, for
each of the R, G and B
channels. It also converts the
signals to HD or SD format. With a performance equivalent to the
processors used in many higher-end HD cameras, this DSP
delivers beautiful images in all video formats.

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 is 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 images that result are enhanced by a
visually wide dynamic range.

7-Mode Gamma for Richer Gradation

Drawing on technologies developed for the VariCam, Panasonic
has equipped the AG-HPX171 with advanced gamma functions
that address seven different shooting scenarios and enhance
your creative abilities. This includes the Cine-Like Gamma, which
produces the characteristic warm tone of film recordings.
HD NORM Mode

AG-HPX171 Gamma Modes

HD NORM: Suitable for HD recording
LOW: Works to flatten out a high contrast scene
SD NORM: Normal setting for SD
(this was available in the DVX100 series)
HIGH: Provides more contrast and color gradation
B.PRESS: Provides more contrast and blacks in low contrast scenes
CINE-LIKE D: The Cine-Like mode shifted to prioritize dynamic range
CINE-LIKE V: The Cine-Like mode shifted to prioritize contrast
