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

F1: —

F2: FLUO.

Indoor shooting under fluorescent lights

F3: SPARK

Emphasis on high detail in subjects at receptions,

dinners 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 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
