High Dynamic Range Image Formation and Motion De-blurring in CMOS Image Sensor


Stanford Reference:

01-018


Abstract

Blurring due to object or camera motion during image capture can cause substantial degradation in image quality. The previously developed image blur restoration methods have limited applicability and their computational burden can be quite substantial. A method of simultaneously constructing a high dynamic range image and performing motion blur restoration during image captures using CMOS image sensor is invented. Our method operates completely locally and recursively, requiring the storage of only a constant number of values per pixel. These modest computational and storage requirements make it feasible to integrate all needed memory and processing with the image senor on a single CMOS chip.

Applications


  • Imaging
  • Digital cameras

Advantages


  • New image processing techniques used to identify blur and restore the image.
  • Can simultaneously form a high dynamic range image and reduce or eliminate motion blur.
  • Modest computational and storage requirements make it feasible to integrate all the processing and memory needed with the image sensor on the same CMOS chip
