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 1080/25p, 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 lowers power consumption and enables high-speed drive, 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-HPX370 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.

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-HPX370 series
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-HPX370
series 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.

*Selecting this 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.
Slow, Synchro and High-Speed Shutter
The shutter speed can be set between 1/6.25 second on the slow end in
50Hz mode (1/6 second in 59.94Hz mode) 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-HPX370 series also features a synchro scan function for capturing
screen shots from a computer monitor.
