ABSTRACT
The image quality of a digital viewfinder is considerably lower than that of a through-the-lens optical system. While the sensor may be capable of capturing 10 or 20 megapixels, the screen of the viewfinder is typically constrained to resolutions under 1 megapixel. The limited resolution makes it impossible to discern all the small details of the captured image. Small blurs and noise that are present in the full-size image can render the image unusable for certain tasks, yet these artifacts may be too small to be discernible in the downsampled version shown on the camera viewfinder.

High-quality image deblurring with panchromatic pixels
Image deblurring has been a very challenging problem in recent decades. In this article, we propose a high-quality image deblurring method with a novel image prior based on a new imaging system. The imaging system has a newly designed sensor pattern ...
Disparity-preserving image rectangularization for stereoscopic panorama
AbstractThis study aims at generating a long strip stereoscopic panorama with a rectangular boundary from a stereoscopic video. The issues arising from this goal are how to automatically select appropriate frames to reduce geometric distortion in image ...
High-quality non-blind image deconvolution with adaptive regularization
Non-blind image deconvolution is a process that obtains a sharp latent image from a blurred image when a point spread function (PSF) is known. However, ringing and noise amplification are inevitable artifacts in image deconvolution since perfect PSF ...
