High Resolution 2.2-megapixel CCD (AJ-HPX3700)
For the AJ-HPX3700, Panasonic
developed a high-density
2.2-megapixel 2/3-inch CCD
that provides high-resolution
full-pixel (1920 x 1080) HD
images. The AJ-HPX3700
provides a choice of
progressive/interlace HD video
formats, supporting native 1080
23.98p/24p/25p/29.97p, as well
as 1080 50i and 1080 59.94i.
The camera offers a high F10
sensitivity at 2000 lux when operating in 1080i.
1-Megapixel Progressive CCD (AJ-HPX2700)
The AJ-HPX2700's 1-megapixel 2/3-inch progressive CCD
combines with a digital signal processing (DSP) circuit to output
high-quality 1080/720 HD images.*
1 In 720p mode, it provides
variable frame rate recording over the full 1 to 60 fps range.
The camera's high F10 sensitivity allows shooting in light as
low as 0.021 lx.*

*2: Shooting at F1.4 in variable frame rate mode at 1 fps, with +30dB gain up.
Chromatic Aberration Compensation (CAC)
This exclusive technology works between lens and camera, allowing
for a highly sophisticated algorithm to be deployed that
automatically compensates the registration error that is caused
mainly by lens chromatic aberration, and minimizes the neighboring
blur. By using a CAC-compatible zoom lens, the P2 VariCam Series
can obtain images similar to those captured with a prime lens.
14-Bit Digital Processing with 12-Axis Color Correction
We offer a 14-bit A/D conversion system along with the new high-
performance DSP circuit. The 12-axis color correction matrix lets
you make fine adjustments in specific color regions. Functions such
as skin detail let you further fine-tune the image.
Scan Reverse Function for Film Lens Use
The P2 VariCam Series can use an ultra prime lens and even an
anamorphic lens adapter that creates a 2.35:1 aspect image for
wide-screen cinematic shooting without cropping the image. Its
scan reverse function cancels the image inversion that occurs when
Angenieux's HD lens adaptor is used.
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 is
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.
Seven Gamma Modes Including VariCam Film-Rec
The DSP circuit in the P2 VariCam Series 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. When using HD SDI dual-link output with the AJ-HPX3700,
images recorded in Film-Rec gamma mode can be converted to
P-10Log gamma, or "live" P-10 Log content can be recorded to
external devices for high-end digital cinema production.
AJ-HPX3700/HPX2700 Gamma Modes
HD:
A video gamma curve for HDTV
SD: A video gamma curve for SDTV (higher gain in dark areas)
FILMLIKE 1: For FILMLIKE TV production. This reproduces gradation in
highlight areas more clearly than the HD gamma.
FILMLIKE 2: Smoother film-like characteristics than FILMLIKE 1
FILMLIKE 3: Smoother film-like characteristics than even FILMLIKE 2
FILM-REC: For film-style image capture, provides low contrast
wide dynamic range
VIDEO-REC: For cinema production that is also suitable for video display
