Abstract
In a system built from an imaging device and an output device, camera shake compensation is performed while processing load imposed on the imaging device is being lessened. An image processing system is built from a digital camera and a printer. Image data pertaining to a subject are recorded in a recording medium. Further, the amount of blurring of the digital camera is detected by means of a gyroscopic sensor, and PSF data are recorded in the recording medium. The printer is equipped with an image conversion section, a PSF conversion section, and an image restoration section, and a resolution of the image data and a resolution of the PSF data are converted, thereby restoring an original image.

Optical navigation apparatus with defocused image compensation function and compensation circuit thereof

TL;DR: In this paper, an optical navigation apparatus with defocused image compensation function and a compensation circuit was presented. But the compensation circuit is configured to transform the first image and a point spread function of the light source into a first conversion result and a second conversion result in frequency domain, respectively, and then transform a result multiplied by the first conversion results and a reciprocal of the second conversion results from frequency domain to time domain to generate a second image.
