Engineering:TruePic
TruePic is the name Olympus has given its image processing engine, based on the Panasonic MN103 architecture. The second version was named TruePic Turbo. In 2007 Olympus began to equip its digital cameras, both compact and D-SLRs with the then latest version, TruePic III.[1]
TruePic III
With this engine its ability to reproduce colours naturally was improved. For this, the Advanced Proper Gamma III technology was enhanced to independently control luminance and chrominance 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 smooths 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.
This engine also provides a speed improvement so 3 FPS image sequences are possible even with a 10-megapixel resolution.
Newer TruePic versions
The TruePic III+ is an improvement of the previous engine use in E450 DSLR, E620 and E30 (if not wrong, but use in E450 is confirmed).
The TruePic V engine is used in the Olympus Pen E-P1, E-P2, E-PL1 and XZ-1.[2] Advantages include faster processing time and nicer colour.
The TruePic V+ engine is used in the Olympus E-5.[3]
The TruePic VI engine is used in the Olympus Pen E-P3, E-PL3, E-PM1, TG-1, XZ-2, OM-D E-M5 and E-PL5.
The TruePic VII engine is used in the Olympus Pen E-PL7, E-PL8, OM-D E-M1, OM-D E-M10, OM-D E-M10 Mark II, OM-D E-M5 Mark II, PEN-F, Stylus SH-2, and Air A01.
The TruePic VIII engine is used in the Olympus OM-D E-M1 Mark II, E-M10 Mark III, E-M10 Mark IV,Pen E-PL9, E-M1X and OM-D E-M5 Mark III. The TruePic VIII Image Processor uses a dual quad core system with four CPU cores and four image processing cores that achieve image processing speeds approximately 3.5 times faster than the TruePic VII Processor.[4] The E-M1X uses two TruePic VIII processors for more processing power. This processing power is used for image stabilization in combination with Hand Held High Resolution shooting, and for AI subject recognition.
The TruePic IX engine is used in the Olympus OM-D E-M1 Mark III.
