AE Automatic Exposure, Electronic Shutter Functions

AE (Automatic Exposure)

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.

AE Level

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

AE Speed

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

AE Area

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

Multi

Mid

Slit

Large

Spot

Manual

Electronic Shutter Functions

Variable speeds

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.

Clear Scan™ Function

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.

CCD IRIS Function

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.

Other Features

Bayonet mount

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.

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.

GAIN (0 dB)

GAIN (18 dB)

HYPER GAIN

Color Shading compensation

Allows for verification of color on a microscope.

RGB, component,

Y/C and composite video outputs

RS-232C controllable

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 ideal for capturing still images.

White Balance modes

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

Extended Genlock

(VBS Genlock and HD/VD in/out)

Allows for synchronization of signals with frame grabber boards.

Synchronization capabilities (Strobe function, WEN output)

Realizes full vertical resolution of fast moving objects.

DXC-990P, DXC-990 specifications

The Sony DXC-990 and DXC-990P are high-definition broadcast cameras known for their exceptional image quality and reliable performance in professional video production environments. Launched in the late 1990s, these cameras quickly became popular in both broadcast and industrial applications due to their robust build and versatile capabilities.

At the heart of the DXC-990 series is its advanced imaging technology, featuring three 2/3-inch IT CCDs (Interline Transfer Charge-Coupled Devices). This configuration allows for superior color reproduction and enhanced light sensitivity, which is crucial for capturing high-quality images in various lighting conditions. The camera's resolution reaches up to 720x486 pixels, enabling it to deliver sharp and vibrant images that meet the demands of professional broadcasters.

One of the standout features of the DXC-990 and DXC-990P is their dynamic range and low noise operation. The cameras are designed to minimize electronic noise, providing clear images with excellent contrast, even in challenging lighting scenarios. This characteristic is instrumental for live events and other fast-paced productions where maintaining image quality is essential.

The DXC-990 also incorporates advanced signal processing capabilities, including digital signal processing (DSP). This technology ensures that images are not only sharp but also render accurate colors with minimal distortion. The camera's built-in color correction options allow operators to tailor the image output to meet specific production requirements, enhancing the creative possibilities for filmmakers and broadcasters.

Another significant advantage of the DXC-990 series is its modular design. This flexibility allows users to interconnect different accessories, such as lenses and viewfinders, making it a versatile choice for various shooting styles and environments. The DXC-990P model, in particular, was designed for portable applications with a lightweight configuration, making it ideal for ENG (Electronic News Gathering) purposes.

Moreover, the cameras support a range of output formats, including analog and digital, ensuring compatibility with various broadcasting systems. The ability to switch between formats adds to the overall utility of the DXC-990 and DXC-990P in a variety of production settings.

Overall, the Sony DXC-990 and DXC-990P are exemplary models that combine high-performance imaging, robust construction, and versatile features, making them suitable for professional video production across different sectors.
