Title:
- Quality-preserving image downsizing

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.
