2.2.2. 16-bit A/D-Converters
Further key elements to improve the overall performance of the new HDC-series are
the new high-resolution 16-Bit A/D-converters.
Compared to the 14-Bit A/D-converter technology of the predecessor HDC-1500R, it
means a 4x higher resolution of the gamma curve, resulting in a better lowlight and
highlight handling, providing a wider dynamic range and giving a more natural colour
reproduction.
At the same time, Signal-to-Noise (SNR) performance could be improved by keeping
the sensitivity on the high level of the HDC-1500R-series (i.e.: F=11 @ 2000lx / 0dB
gain, 89.9%-Reflectance, 3200K, 1080/50i format).
Due to the new construction of the A/D-converters, power consumption of the
converter could be reduced (less heat, less power consumption of the entire system).
2.2.3. Newly developed DSP (Digital Signal Processing)
The last key element to increase the overall performance of the new HDC-series was
the development of the new DSP, which now includes 3 new ASICs.
The new DSP works with a very high accuracy and allows the integration of new key-
features as described in chapter 2.5.
2.2.4. Summary: State-of-the-Art Performance
Based on the improved POWER-HAD-FX CCD sensors, the newly developed 16-bit
A/D-converters and the new DSP, the new HDC-2500-series features an enhanced
performance and unrivalled picture quality which finds issue in the basic
specifications:
