The Sony DXC-990/990P is a 1/2 type DSP 3-CCD Colour video camera which incorporates ExwaveHAD™ technology – a new Sony technology that greatly improves camera sensitivity (F11 at 2000 lx) while reducing smear.
With high picture quality and so many functions, the DXC-990/990P is the ideal choice for a variety of applications
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.
Superior Picture Quality – ExwaveHAD CCDs
The DXC-990/990P incorporates 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 pictures 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 combinationof ExwaveHAD technology, improved electronic circuitry and advanced video processing results in an excellent signalto-noise ratio of 63 dB (NTSC) and 62 dB (PAL)
Picture Contrast 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.
DCC + (Dynamic Contrast Control Plus)
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.
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 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.
DSP (Digital Signal Processing)
The DXC-990/990P incorporates 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 has several DSP functions for powerful picture controls.
Picture Enhancement Controls
Adjusts the sharpness of the object outline with minimal noise. This feature also enables horizontal detail frequency control.
Provides sophisticated electronic adjustment for accurate colour reproduction by adjusting colour saturation and hue.
Allows a particular colour 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.
AE (Automatic Exposure)
AE automatically controls the level of brightness by varying the exposure times. This is done by combining the CCD IRIS function, AG C (Automatic Gain Control), and Auto Iris function of the lens. The DXC-990/P is equipped with a number of convenient AE modes.
Adjusts the standard brightness level by up to +/- one F-stop in a lens iris.
Selectable AE (Auto Exposure) conversion speed to suit applications under varying lighting conditions.
AE Area is a light metering system that includes six different modes.
Electronic Shutter Functions
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/P features 10 different shutter speeds (OFF to 1/100,000), including flickerless mode.
Long term exposure
The shutter speed can be manually selected from 1 to 255 frames (field mode) or 2 to 256 frames (frame mode) in oneframe steps or from 0.1 to 8.0 seconds.
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.
The DXC-990/990P is designed to accept high quality bayonet mount lenses so that it can adapt various kinds of professional lenses. The strong points of bayonet mount lenses include higher sensitivity and lower colour 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 function.
Scene Files and User Files
• 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.
Hyper Gain (+30 dB)
High sensitivity mode used for shooting objects in very low light conditions.
Colour Shading compensation
Allows for verification of colour on microscope.
RGB, component, Y/C and composite
Easy control and operation of the camera by an external computer is possible.
Field or Frame integration mode
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 good for capturing a still image.
