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

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

Flash Band Compensation

In contrast with the CCD image sensor, which accumulates still images of
single frames that are exposed with identical timing, the MOS image sensor
uses a rolling shutter system that sequentially scans each line of pixels.
This enhances low power consumption and low light performance. But
because the exposure timing differs for each line, when an external flash is
used, it tends to produce images where the brightness is divided between
the top and bottom of the image. This is called the flash band effect.
The AG-HPX300 Series is equipped with highly accurate flash band
detection and compensation software* on the camera’s signal processing
LSI. By generating pairs of frames containing flash bands, and frames in
which a flash extends from the previous frame to the entire screen, and
then using the compensation process to adjust the level, the flash band
effect of MOS-based imagers is eliminated.

*This software is equipped on products shipped in or after July 2009. Users with products from
before that time can receive this by upgrading their software. Visit this website for more details:

3-Position Gain Selector / 24dB Gain-Up Function

There is a 3-position gain selector, with L, M and H settings. To each setting
you can assign a gain value from −3 dB to 12 dB, in 3

dB steps. There is

also a USER button –- just give it a quick touch to instantly boost the gain
by 24 dB.

Newly Developed 20 bit Digital Signal Processor

The AG-HPX300 incorporates a high-
performance 20 bit DSP that handles
image rendering processes such as
gamma and various detail
enhancement functions with
exceptional precision. Consuming
less power than conventional
processors, the new DSP contributes
to the AG-HPX300’s outstanding
environmental performance.

Scene File Dial

Set this 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. You can also store and load the settings to and from an SD Card.

• File Description

F2: FLUO.

*Selecting this file does not change the video recording format. If you want to switch between 24p
and 30p, you must do so as a separate procedure.

Slow, Synchro and High-Speed Shutter

The shutter speed can be set between 1/6 second on the slow end and
1/2000 second on the fast end. Used with the variable frame rate function,
this allows you to create a blurring effect or crystal-clear stop-motion of
sports action. The AG-HPX300 also features a synchro scan function for
capturing screen shots from a computer monitor.

Advanced Image Adjustments Built-In

• Matrix setting including a Cine-Like mode
• Adjustable H detail level, V detail level, detail coring and skin tone detail
• Adjustable chroma level, chroma phase, color temp and master pedestal
• Knee point settings: Auto, Low, Mid and High
• User files can be saved to an SD card and shared with other cameras.

User files are separate from Scene files.

• 4-position (off, 1/4 ND, 1/16 ND, 1/64 ND) optical neutral density filter
