DSP with 14-Bit A/D Conversion and 19-Bit Processing
The digital signal processor
developed for the AG-HPX170
series’s 1080/60p video signals
uses 14-bit A/D conversion and
19-bit inner processing to
attain unprecedented accuracy.
While the camera does not
record 1080/60p, it is from this
capture that all other signals
are made. The DSP performs a
variety of adjustments,
including eight 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-HPX170 series with advanced gamma
functions that address eight different shooting scenarios and
enhance your creative abilities. This includes the Cine-Like
Gamma, which produces the characteristic warm tone of film
recordings.
AG-HPX170 series 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 contras 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
