With this engine, its ability to reproduce colours naturally was improved. For this, the Advanced Proper Gamma III technology was enhanced to independently controlluminance andchrominance difference signals for more faithful reproduction of pale colours. Also, individual colours can be corrected without affecting the reproduction of other colours. Colour reproduction was fine-tuned so that they are not just correct but also appear pleasing to the human eye. As a result, human skin colours and the blue of the sky can be reproduced more faithfully.The Advanced Noise Filter III contributes to a high-quality reproduction of images through the reduction of noise by isolating the image and noise signals more accurately. It replaces the real space (real image) with a frequency space and extracts the signal component. It then smoothes out the signal components while preserving the edges.
To reproduce edges smoothly but still sharply, the Advanced Detail Reproduction technology detects edge direction and applies a Low Pass Filter (LPF) in the edge direction and a High Pass Filter (HPF) in the edges normal line direction. This way edges become smooth and false colours are eliminated.
The new engine also provides a speed improvement so 3fps image sequences are possible even with a 10 megapixel resolution.
