This study introduces a hybrid camera that measures its own motion during image capture. This allows for effective deblurring of motion-blurred images, outperforming existing methods with minimal resources.

Area of Science:

  • Computer Vision
  • Image Processing
  • Optical Engineering

Background:

  • Motion blur significantly degrades image quality, posing a challenge for image restoration.
  • Existing solutions include blind restoration, optical stabilization, and specialized sensors, each with limitations.

Purpose of the Study:

  • To develop a novel hybrid camera system capable of measuring its own motion during image integration.
  • To leverage acquired motion data for accurate motion deblurring.

Main Methods:

  • Exploiting the spatial-temporal resolution trade-off to design a hybrid camera.
  • Measuring camera motion during image integration to compute the point spread function (PSF).
  • Utilizing the computed PSF to deblur motion-blurred images.
