DRS (Dynamic Range Stretch) Function
DRS recognizes the average brightness of highlight and shadow
areas and then automatically adjusts the aperture and uses knee
control to suppress blocking in the shadow areas. In scenes with
mixed dark and light areas, DRS automatically provides a wider
dynamic range with minimal blown highlights and blocked shadows.
Two new color saving modes (Mode 1: Natural color, Mode 2: Vivid
color) for high-brightness effects and a depth (3 steps for
compression level) setting function have been added to improve
adjustment.
Maximum 4x Digital Zoom
Digital zoom electronically increases the magnification rate of the lens
by 2x, 3x or 4x. HD images retain their superior resolution even with
zooming, and — unlike when a lens extender is used — brightness is
not reduced.
* The digital processing effect is perceptible in the image when x3 or x4 zoom is used.
Seven Gamma Modes Including VariCam Film-Rec
The DSP circuit in the
AJ-HPX3100 has seven
selectable gamma modes. These
include Film-Rec and Video-Rec
gamma for movie production,
which are the same modes
incorporated in the VariCam.
• AJ-HPX3100 Gamma Modes
HD:
For HDTV
SD:
For SDTV (higher gain in dark areas)
FILMLIKE 1:
For film-like TV production. This reproduces gradation
in highlight areas more clearly.
FILMLIKE 2:
Smoother characteristics than FILMLIKE 1
FILMLIKE 3:
Smoother characteristics than even FILMLIKE 2
FILM-REC:
For film-style image captures, provides low contrast
and a wide dynamic range
VIDEO-REC:
For cinema production that is also suitable for video display
Scan Reverse Function for Film Lens Use
The AJ-HPX3100 scan reverse function cancels the image inversion
that occurs when Angenieux or Canon HD lens adaptors are used.
Scene Files and Lens Files
• Scene Files: Store specific camera settings. Four files with settings
can be stored in the camera unit, and eight files can be stored on an
SD/SDHC memory card. The files can be copied between the
camera’s memory and the SD/SDHC memory card.
• Lens Files: Store settings for interchangeable lenses. Eight files can
be stored in the camera unit, and 64 (8 x 8) files can be saved on an
SD/SDHC Memory Card.
Focus Assist Function
This function simplifies focusing
by displaying, in graph form, the
frequency distribution of the
incoming signal in the viewfinder
and LCD monitor.
5 User Buttons
The User buttons let you turn frequently used functions on or off with
a single touch. In addition to USER MAIN, USER 1 and USER 2, you
can change SHOT MARK and TEXT MEMO to other functions if
desired.
AWB with Wide Adjustment Range and
Advanced Functions
The auto white balance (AWB) function offers a wide color
temperature adjustment range of up to 15000 K. The two-value
memory/1-value preset enables quick switching. The color
temperature can be adjusted with the jog dial after the white balance
is set. A subject-following ATW (auto tracking white) function is also
provided.
Optional Color and Black-and-White Viewfinders
The optional AJ-CVF100G HD Color Viewfinder employs a 25.4 mm
(1 inch) 1,500,000-dot-equivalent (960 x 540 x 3 [RGB]) transmission-
type LCOS (Liquid Crystal On Silicon) to achieve high resolution, high
brightness and high response. It helps to reduce the possibility of
white balance adjustment errors and other errors in recording.
The optional AJ-HVF21KG 50.8 mm (2 inches) Black-and-White HD
Viewfinder can also be used.
Versatile Shooting Assist Functions
• Electronic Shutter with Half-Speed: The AJ-HPX3100 features
six shutter fixed speeds of up to 1/2000 sec., plus “half-speed”
(180 degree) and synchro-scan capability.
• Two optical filters, ND and CC, have four positions each. The
3200K, 4300K, 5600K and 6300K positions of the CC filter help to
express deeper colors.
• Mode Check: Displays a list of the camera settings on the
viewfinder and LCD monitor.
• Zebra: Select any two levels from among 0% to 109%, in 1% step.
• Y-GET: Measures brightness at the screen center and displays
precise numerical data.
• A 3 point locking viewfinder mount allows precise adjustment.
• The large Audio volumes (4ch) feature a push lock function.
• The Audio Input level adjustment (front) can be switched ON/OFF
and allocated to desired channels.
