METHOD FOR ENHANCING IMAGE QUALITY WHILE ZOOMING INTO PICTURES

摘要

ABSTRACT The various embodiments of the present invention disclose a method for enhancing image quality while zooming into pictures using a Region of Interest (ROI) based residue extraction technique, wherein the residue is stored as a part of the original image metadata and enhance the image quality for higher zoom ratios while viewing pictures in gallery by utilizing the residue to generate a super resolved image. The method herein comprising receiving a request to zoom into the captured image, determining zoom levels for each Region of Interest (ROI) in the captured image, calculating a super resolved ROI at desired zoom level using multiple captured images, calculating the ROI based residual data between super-resolved and captured image at different zoom levels, compressing and storing the residual data at one point in time, decompressing and restoring data for reconstructing super- resolved image at another point in time and displaying an enhanced captured image.
