Camera correcting lens distortions?
"Matthias Heiler" wrote in message
... Hi group, Is there a camera that electronically corrects geometrical lens distortions (esp. Barrel)? For the fixed-lens digital cameras out there this should be not hard to implement. It also would manufacturers allow to use cheaper/lighter glass on their consumer products and still get decent image quality. On a similar note, does anybody know a decent lens-distortion correction software for Linux? It should be able to work on many images automatically, without manual intervention. Thanks, Matthias There may be software to correct lens imperfections: http://www.dpreview.com/news/0405/04...oopticspro.asp Mark |

... [] Not exactly in camera yet, but looks interesting: http://www.dpreview.com/news/0402/04...oopticspro.asp Bart Thanks for that pointer - they don't seem to include my Nikon 5700 as yet. What an awful Web site, though! New windows seem to open for every link clicked. It puts me right off! Cheers, David |

It would be cheaper to just build a better lens. Historically, prices for computer chips have declined _much_ faster than prices for lenses. In addition, once you have electronic Barrel correction your design space for lenses will change: You might be willing to trade slightly higher Barrel (which can be calculated away) for more sharpness or less CA (which is harder to correct ex post) or less weight. |

Probably a bit too complex for their program to work out! Or they reckon those with expensive cameras have the money to purchase their software! Cheers, David |

We were discussing the possibility of doing the correction in-camera, so that lenses could perhaps be made cheaper, smaller or less complex. The hardware-software trade-off. One stand-alone program designed for a limited range of DSLRs was pointed out as an example. Cheers, David |

Cheers, David Ah thanks, I don`t see why it can`t be added in the future to cameras own processing or it could just be calibrated at factory for ranges of lenses. regards, Zol. |
