State-Of-The-Art Picture Quality - Sony HDC-25 Series Technical Information

Technical Information: Sony HD System Cameras

2.2. State-of-the-Art Picture Quality

Although, the new HDC-series is based on its predecessor, the famous HDC-1500R-
series, it features 3 newly developed core technology elements which finally deliver a
drastically improved picture quality compared to the HDC-1500R-series:
 Newly developed 2/3"-POWER-HAD-FX CCD sensors
 16-bit A/D-converters
 Newly developed DSP (Digital Signal Processing)
2.2.1. Newly developed POWER-HAD-FX CCD sensors
The newly developed 2/3"-POWER HAD FX CCD sensor is based on the latest IT-CCD
design and is Sony´s 3
Starting from 2005, when POWER HAD FX sensors were used in the HDC-1500-series
for the first time, these sensor types were used in a variety of HD system cameras so
that the user may expect a perfect colour-matching when using various Sony HD
system cameras types together.
Picture 2 shows the development of the POWER HAD FX sensor technology
Improvements were made in the design of the sensor, thus increasing the V-smear
specification, the Depth of Modulation (DoM) and giving a better overall SNR
performance (Signal-to-Noise Ratio) while keeping the high level of standard
sensitivity (F=11@2000lx/1080i mode).
HDC-25xx Series features a digital noise reducer function (NS = Noise Surpression).
This function is available only for HDC-25xx series and is adjustable from RCP and
MSU. Thus, noise level in the picture can be decreased from -60dB (basic
specification w/o NS function) to -64dB (NS set to 100%). The function is individually
adjustable in 10 steps (from NS: Off to NS: 100%).
