he Sony DXC-990/990P is

a 1/2 type DSP 3-CCD

color video camera which

incorporates 

ExwaveHAD™ technology – 

a new Sony technology that

greatly improves camera

sensitivity (F11 at 2000 lx) 

while reducing smear.  

The DXC-990/990P not only

inherits all of the advanced

functions of its predecessor,

the DXC-950/950P, but also

includes improved technology

and innovative features for

versatile operation in the same

body size.  Allowing use of a

high quality Bayonet mount

lens, and providing a

resolution of 850 TV lines and

high S/N ratio,

the DXC-990/990P is ideal for

applications such as

microscopy, industrial

inspection and remote camera

systems where picture

accuracy and detail are

important.  Incorporating new

10-bit DSP technology,

a user friendly on-screen

menu allows for simple control

of various features including a

DynaLatitude™ function,

Partial Enhance, and a wide

selection of Automatic

Exposure (AE) modes.

The DXC-990/990P incorporates newly developed 1/2 type IT (Interline Transfer)
ExwaveHAD technology. Inheriting the unique sensing technology of 
the DXC-950/950P, the DXC-990/990P attains a high sensitivity of F11 at 2000 lx
while the improved HAD sensor structure drastically reduces smear level. This
permits images of the highest quality to be captured in difficult lighting
conditions. With the high packing density of these CCD image sensors and their
accurate spacial offsetting, a remarkably high horizontal resolution of 850 TV
lines is achieved. The combination of ExwaveHAD technology, improved
electronic circuitry and advanced video processing results in a high
signal-to-noise ratio of 63 dB (NTSC) and 62 dB (PAL).

Adjusts the sharpness of the object outline with minimal noise.
This feature also enables horizontal detail frequency control.

Provides sophisticated electronic adjustment for accurate color reproduction by
adjusting color saturation and hue.

Allows a particular color to be selected, and its hue, saturation and detail
altered. In addition, the detail produced by the high resolution of the camera can
be softened or emphasized in certain parts of the image by the Partial Enhance
function.

(This includes CCD, PRISM and Optical Filter Data)

AE automatically controls the level of brightness by varying the exposure times.
This is done by combining the CCD IRIS

®

function, AGC (Automatic Gain Control),

and Auto Iris function of the lens. The DXC-990/990P is equipped with a
number of convenient AE modes.

Adjusts the standard brightness level by up to + / - 0.5 F-stop in a lens iris.

Selectable AE conversion speed to suit applications under varying lighting
conditions.

A variable speed electronic shutter is built into the CCD imager, making it
possible to capture blur-free, clear images of high speed moving objects.
The DXC-990/990P features 11 different shutter speeds (OFF to 1/100,000),
including flickerless mode.

The DXC-990/990P is equipped with a bayonet mount so it can
adapt various kinds of high quality, professional lenses. The strong
points of bayonet mount lenses include higher sensitivity and lower
color shading compared with C-mount lenses. A hot-shoe
connection is also provided to eliminate the need for a lens-to-
camera interconnecting cable, providing easy remote control of
zoom, focus and iris functions.

Allows for synchronization of signals with frame grabber boards.

Realizes full vertical resolution of fast moving objects.

Scene Files: The preset files are set to accommodate four different
situations (Standard/Microscope/Full Auto/Strobe). Copying the
settings between two files is also possible (File A/B).
User Files: Allows user to set two custom parameters in the menu
for instant recall.

High sensitivity mode used for shooting objects in very low light
conditions.

Allows for verification of color on a microscope.

Easy control and operation of the camera by an external computer is
possible.

The DXC-990/990P has the ability to switch between Field or Frame
CCD integration modes. Field integration is effective for capturing
moving objects, while Frame integration is ideal for capturing still
images.

AWB, ATW-Normal/Wide, MANU, Preset 3200K/5600K

The Clear Scan feature eliminates the horizontal bands that appear across the
screen when shooting a computer display. This is achieved by matching the
camera shutter speed with the display scanning frequency.

When the level of incoming light exceeds the auto iris adjustment range, the
CCD IRIS function automatically reduces the exposure in a range equivalent to
10 F-stops.

AE Area is a light metering system that includes six different modes.

The on-screen menu feature allows for quick and easy picture adjustments
while viewing the image. All camera control functions are accessible from
the side panel of the camera or through the optional RM-C950.

By adjusting the knee, a knee point and knee slope are set so that the
highlighted areas of the picture can be clearly reproduced.
High/Normal/Low switchable

The DXC-990/990P incorporates a new Sony 10-bit DSP technology.
DSP enables a variety of enhancement features and increases picture reliability
that cannot be achieved with analog signal processing.
The DXC-990/990P features several DSP functions for powerful picture controls.

Automatically adjusts contrast corresponding to the brightest signal level of the
entire image. Clear images can be captured if both bright and dark areas exist
within the image.

Avoids hue factor distortion that can occur when subjects are very bright. DCC+
also automatically adjusts the knee point according to the contrast of the image.

Black stretch/compress enhances the gradation of the dark area by
stretching or compressing the range of the image.
