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.
High-intergrity 14-bit A/D Conversion
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.
