DxO Optics Engine — 3rd generation
At the very heart of DxO Optics Pro, the award-winning DxO Optics Engine uses unique hardware modeling to automatically eliminate optical defects.
Based on sophisticated models of camera and lens performance, DxO Optics Engine automatically removes:
• lens distortion
• vignetting
• lens softness
• chromatic aberration
and with input from the user, can also apply perspective corrections (keystoning, horizons).
To implement DxO’s unique Optical corrections on a particular combination of camera and lens, thousands of scientifically set-up pictures are taken by our lab team, and then processed to produce a mathematical model of imaging performance. DxO Optics Engine then uses this model – called a DxO Correction Module – to reverse imaging defects and improve image quality.
• All relevant shooting parameters (focal length, focus distance, aperture, ISO, resolution, etc.) are automatically taken into account
• Complex problems such as lens astigmatism, complex distortion (mixed barrel & pincushion), etc. are resolved
• Corrections are performed on an individual pixel level because different points in the image are subject to different optical aberrations
• DxO Optics Engine includes specific technology to avoid increasing image noise when performing corrections
DxO Optics Engine – now in its third generation – is a core component of DxO Optics Pro that is responsible for solving geometrical and optical problems in digital images.
The first generation of the DxO Optics Engine eliminated any type of geometric distortion (barrel / pincushion or mixed) to yield that holy grail of lens designers — a rectilinear image.(1)
The second generation offered MaxImage that allowed the user to retain the largest possible image after distortion correction.
The third generation, available since DxO Optics Pro version 4, builds upon this solid foundation to introduce revolutionary new features to widen your choice of lenses and provide unmatched control over image geometry:
• Unique, simple to use, semi-automatic correction of volume anamorphosis
• Sliders and image overlay for rapid keystoning correction – acts like a shift lens
• Easy image rotation to correct for tilted horizons and straighten verticals
• Circular fisheye distortion removal to “defish” these extreme lenses
With all these improvements, DxO Optics Pro v5 now offers an unrivalled set of image geometry controls, thus fully justifying DxO Optics Pro’s leading position in automatic image enhancement.
(1) This means that what were originally straight lines in the real world remain straight lines in the DxO corrected image. For a long time, designers have been obliged to make constant trade-offs when designing lenses.
