Deblurring (iDeb)

Imatrics Deblurring (iDeb), on which Imatrics holds an international patent [1], efficiently sharpens blurred images. Blurring in digital images may be due to a number of causes:

• Out of focus.
• Movement.
• The propagation medium (normally the atmosphere).
• Imperfections in the optics.

Examples and applications: 

• Simplification of optical systems: iDeb makes it possible to reduce costs in designing and manufacturing the optics of capture devices while maintaining or even enhancing final image quality.

• Enhancement of images shot with imperfect optics.

• Enhancement of out-of-focus shots taken with an infrared camera.
