On-chip column A/D conversion with dual NR
Thousands of parallel analog/digital converters in the sensor convert light to
digital signals with utmost precision and speed. Before and after conversion, the
sensor cancels noise to ensure exceptionally clean 14-bit signal output at all ISO
settings. By performing analog/digital conversion and dual noise reduction on
the chip itself before image processing, the a99 produces images of exceptional
quality and clarity.
Multi-segment optical low-pass filter
Unlike conventional optical low-pass filters that degrade image
resolution when suppressing moiré, Sony’s new multi-segment
optical low-pass filter effectively maintains high-resolution detail.
This achievement was made possible by proprietary multi-segment
technology from Sony’s professional broadcasting equipment that
subtly controls the distribution of image points.
