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.

• File Description

F1: —

F2: FLUO.

Indoor shooting under fluorescent lights

F3: SPARK

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 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.
