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.
