DXC-D50 Series Digital Video Camera

Since the first models, the Sony DXC-series of production video
cameras have been widely accepted for use in a number of
professional video-acquisition applications because of their superb
picture quality and operational performance.

The DXC-D50/D50WS is the next-generation in the DXC-series of
cameras, designed for even greater picture quality and operational
convenience. These cameras are offered in two different versions:
the DXC-D50 4:3 model and DXC-D50WS 16:9/4:3-switchable
model. Both feature the new high-performance Power HAD™ EX
CCD sensor and precise 12-bit A/D conversion built into a highly
sophisticated LSI. The result is superior picture quality, high
sensitivity, plus low noise and smear characteristics over previous
models. A variety of automatic functions have also been included,
allowing easy and convenient operation in any shooting scenario.

Another important aspect of Sony DXC-D50/D50WS cameras is
their excellent system versatility. Two types of camera control units
are available; the CCU-D50, for multi-core CCU operation, and the
CCU-TX7, for Triax CCU operation. The new RCP-D50/D51
Remote Controllers can also be used with either system.

With a host of sophisticated features, the DXC-D50/D50WS
provides an ideal solution for small studio operations at an
affordable price.

*In this brochure, the DXC-D50 refers to both DXC-D50 for NTSC and DXC-D50P for PAL,

while the DXC-D50WS refers to both DXC-D50WS for NTSC and DXC-D50WSP for PAL.

New Power HAD EX CCDs

The DXC-D50/D50WS camera is equipped with three newly
developed 2/3-inch type Power HAD EX CCDs,

each with a high
density of 1 million/490 K effective (NTSC) or 1.2 million/570 K
effective pixels and offering high horizontal resolutions of 920* TV
lines.

A high sensitivity of F11 (at 2000 lx, 3200 K), an excellent S/N
ratio of 65 dB (NTSC)/63 dB (PAL), and an FIT-like vertical low
smear level of -140 dB (typical) are achieved.

12-bit A/D Conversion

The Sony DXC-D50/D50WS incorporates a high-integrity 12-bit A/D
LSI, so that the high-quality images captured by the Power HAD EX
CCDs are processed with greater precision than conventional 10-bit
A/D LSIs. In particular, this higher bit resolution allows the contrast
to be reproduced more faithfully in mid-tone areas of the picture.

Advanced Digital Signal Processing (DSP)

Another key to quality in a DSP camera is how many bits are used in
its nonlinear processes, such as gamma correction.
The DXC-D50/D50WS camera uses more than 30 bits, minimizing
round-off errors to maintain the CCD's high quality. The DSP LSI of
the DXC-D50/D050WS also enables highly sophisticated image
controls, such as Knee Saturation, and Adaptive Highlight Control
functions.

Natural Color Reproduction with
"Knee Saturation Control"

Traditionally, shooting very bright portions of an object

(such as key light reflections from a person's forehead)

can reduce color saturation and change the hue in

highlight areas.

The DXC-D50/D50WS cameras adopt a Knee

Saturation Control function in which this 'washed-out'

effect on saturation and hue change is reduced to a

minimum, and far more natural color reproduction in

highlight areas is achieved.

Adaptive Highlight Control

In conventional cameras, only a single

knee-point/slope is available for contrast control

over highlights. The DXC-D50/DXC-D50WS

camera, however, provides multiple

knee-points/slopes for superior overexposure

control. The camera analyzes the highlight

areas of a scene and automatically sets and

optimizes multiple knee points/slopes

accordingly. This allows the reproduction of extremely

difficult images (such as an interior scene that includes

a brightly sunlit window) with much more overexposure

latitude. This function applies only to input video levels

in excess of the knee point - the middle and low

luminance parts of the video signal are unaffected by

this control.

Low Key Saturation

With traditional cameras, low-light areas can be

subject to reduced saturation, resulting in the color in

these areas being "washed-out". The Low Key

Saturation function on the DXC-D50 Series helps

eliminate this problem by optimizing the amplification

of color saturation at low light levels, providing more

natural color reproduction.

Cross-Color Suppression

Separating the luminance and chrominance

components of a composite signal can be a difficult

task, even with the most advanced comb-filtering

techniques. In order to keep cross color and cross

luminance to a minimum, the DXC-D50 Series virtually

eliminates frequency components that may result in

such artifacts being generated prior to the signal

output. These frequency components are virtually

eliminated from the Y/R-Y/B-Y signals within the

camera head through sophisticated digital three-line

(NTSC)/five-line (PAL) comb filtering, resulting in a

great reduction of the cross color and dot crawl

normally seen on picture monitors fed with a

composite video signal.

Skin-Tone Detail Control

The Skin-Tone Detail function on the

DXC-D50/D50WS allows softer detail correction to be

applied in the facial area, while maintaining the

sharpness of other parts of the picture.

The Skin-Tone Detail area can be selected simply and

quickly using the Area-Detect Cursor in the viewfinder

screen. The color range for the Skin-Tone Detail (and

skin detail level) can also be selected manually using

the viewfinder menu system.
