The High-Quality DSP Matches Image Processing and Quality to match Each Shooting Situation

20 bit Digital Signal Processor

The AG-HPX250 incorporates 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.

DRS OFF

7-Mode Gamma for Richer Gradation

Drawing on technologies developed for the VariCam, Panasonic has

equipped the AG-HPX250 with advanced gamma functions that address

seven different shooting scenarios, including two Cine-Like Gammas.

Rapid Response with Agile Shooting Assist Functions

Focus Assist Functions

Press the Focus Assist button and the center section of the screen

expands in size, making it easier to determine if the focus is correct.

Also, the Focus Bar that visually indicates the focus level can be

displayed on the screen.

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-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: —

Standard settings

F2: FLUO.

Indoor shooting under fluorescent lights

F3: SPARK

Highlighting subjects at receptions, events etc.

F4: B-STR

Enhanced gradations of luminance in low light scenes

F5: CINE V

Cine-Like setting shifted to prioritize contrast*

F6: CINE D

Cine-Like setting shifted to prioritize dynamic range*

* 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.
