≥

Since both 16:9 and 4:3 aspect ratios are supported and
switching between interlace drive and progressive drive is
possible, the unit can handle a wider range of production
applications.
While progressive drive is used, the signals transferred to
and from the VTR unit are converted into interlace signals.

≥

The unit comes with a storage type gain increase function
that employs progressive drive.  This is a function that
makes it possible to achieve a higher sensitivity of up to 20
dB above the regular gain increase.

≥

The unit is equipped with a digital zoom employing function
that employs progressive drive.  This function is particularly
useful when zooming further in on a subject.

≥

The analog images are processed into digital data by a 12-
bit A/D converter with sampling frequencies of 18 MHz and
by operating the signal processor using the 36 MHz
frequency, it is possible to reproduce images which are
more finely detailed and achieve improvements in stability
and reliability.

≥

Serving as a paint function, this facility enables the colors
for 12 axes to be compensated for independently and is
very useful for creating finely detailed images.

<Note>
The unit is equipped with progressive drive, but due to the
characteristics of the CCD the upper left portion of the screen
may appear slightly brighter than normal when the
accumulative type gain increase function is used to boost the
gain.  In addition, when using progressive drive the video
signal’s dynamic range is approximately half what it would be
during interlace operation.

≥

This function enables one of three gamma types to be
selected.  Two of these types are like the ones used with
films.   This extends the range of image expressions yielded
in production.

≥

When the unit is used on its own, one set of user data and
four sets of scene file data can be registered.  Further, by
using an SD card or a Multimedia Card (optional accessory)
as the setup card, up to eight sets of setup data can be
stored.

<Note>
SD card and MultiMedia card used in this unit do not comply
with the SD standard.  Do not use cards formatted using this
unit with other camera-recorders.  Further, NTFS and
FAT32 formatted cards cannot be used with this unit.
The recommended size for SD cards is 8 MB or more and 4
MB or more for MultiMedia cards.

≥

At the front of the unit is a button for checking the
information concerning the markers on the viewfinder
screen.  This is useful for checking the picture angle, for
instance, during shooting.

≥

The unit supports the AJ-EC3P extension control unit.

≥

It is now possible to adjust the position where the unit is
optimally balanced for operation using a single-touch action.
This means that the operator can easily optimize the unit’s
balance when the lens, battery and other peripheral camera
devices have been installed on the unit.

The AJ-SDX900 is a video camera recorder that integrates a 3-CCD camera unit featuring a 2/3-inch on-chip lens that supports
progressive drive with a VTR unit that in turn supports the DVCPRO and DVCPRO50 formats.
The camera enables either interlace drive or progressive drive to be selected to make the product useful for a wider range of
applications in the field of production.
The unit is both compact and lightweight, and it has a minimal power consumption.  It features a high picture quality and
sensitivity, it has excellent mobility, and it effectively withstands dust, humidity and moisture.  With all these features
incorporated, it can be used even for electronic news gathering activities.
Both the camera and VTR units employ digital signal processing technology to achieve even higher levels of picture quality and
stability and also to produce a system that enables the data to be controlled on the setup card.
