This study introduces a new model for angular motion blur, accounting for space-variant effects. The novel angular-motion-dependent point spread function (PSF) differs significantly from traditional fixed PSFs in imaging systems.

Area of Science:

  • Optics and Image Processing
  • Computational Imaging

Background:

  • Traditional image processing models assume a fixed optics point spread function (PSF) for motion blur.
  • This assumption is insufficient for angular motion, which introduces space-variant aberrations, defocus, and blur.

Purpose of the Study:

  • To develop a novel model for image degradation under angular motion conditions.
  • To formulate a space-variant point spread function (PSF) that accurately represents angular motion effects.

Main Methods:

  • Developed a model incorporating angle-dependent optics PSF and motion PSF as a weighting function.
  • Formulated a combined space-variant PSF for angular motion.
  • Proposed and evaluated an efficient approximation for the model.

Main Results:

  • The new angular-motion-dependent PSF shows significant differences compared to traditional fixed PSFs.
  • The proposed model effectively captures space-variant effects in angular motion imaging.
  • The approximation simplifies the model while maintaining accuracy.

Conclusions:

  • The conventional fixed PSF model is inadequate for angular motion blur.
  • The proposed space-variant PSF model provides a more accurate representation of image degradation.
  • The efficient approximation offers a practical solution for complex angular motion scenarios.
