FEATURES
Excellent Picture Quality
Three-chip 2/3-inch Type
Power HAD EX CCDs
The DXC-D55/D55WS Series is equipped with
the field-proven three-chip 2/3-inch type Power
HAD EX CCDs, offering high horizontal
resolutions of 920* TV lines. These high-
performance CCDs also provide an excellent
sensitivity of F11 (at 2000 lx, 3200K), a
remarkable signal-to-noise ratio of 65 dB
(NTSC)/63 dB (PAL), and an extremely low
smear level of -145 dB (typical).

14-bit A/D Conversion
The Sony DXC-D55/D55WS incorporates a
high-quality14-bit A/D conversion circuit that
allows images captured by the Power HAD EX
CCDs to be processed with four times the
precision than 12-bit A/D converters. In
particular, this higher resolution reproduces the
contrast more faithfully in mid-to-dark-tone
areas of the picture. In addition, the 14-bit
accuracy helps to eliminate pre-knee signal
compression at highlight areas, and allows the
camera to clearly reproduce a high-luminance
subject.
Advanced Digital Signal Processing (ADSP)
A key indicator of quality in a DSP camera is
how many bits are used in its nonlinear
processes, such as gamma correction. The
DXC-D55/D55WS Series uses more than 30
bits, thus minimizing rounding errors and
maintaining the high-quality images captured
by the Power HAD EX CCDs. This advanced
digital signal processing (ADSP) also enables
highly sophisticated image controls, such as
knee saturation, adaptive highlight control, and
skin-tone detail controls.
