AG-HPX255/HPX250
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.
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.
AG-HPX255/HPX250 Gamma Modes
HD NORM:
Suitable for standard HD recording.
LOW:
Works to flatten out a high contrast scene.
SD NORM:
Normal setting for SD.
HIGH:
Expands the tone of dark parts and makes a brighter image.
The contrast softens.
B.PRESS:
Makes the contrast sharper than LOW.
CINE-LIKE D: The Cine-Like mode shifted to prioritize dynamic range.
CINE-LIKE V:
The Cine-Like mode shifted to prioritize contrast.

Panasonic Website (http://pro-av.panasonic.net/).
Three Position Gain Selector plus 30dB Super Gain Function
There is a three position gain selector, with L, M and H settings. To each
setting you can assign a gain value from 0, +3, +6, +9, +12, +15 and
+18 dB. There is also a Super Gain such as +24 dB and +30 dB.
Scene File / User File
Set Scene dial for an instant set of shooting conditions. Six preset files
are provided, and you can change any of the six file names and their
settings as desired. One set can be stored internally in the AG-HPX255/
HPX250, and four sets on an SD Memory Card. One file with camera
setting values can also be stored internally, and four files on an SD
Memory Card.
Scene File Description
F1: —

* Selecting a scene file does not change the video recording format. If you want to switch to 25p, 24p
and 30p, you must do so as a separate procedure.
Five User Buttons
There are a total of five User buttons: User Main, User 1 to 3 on the top
