A METHOD FOR LOCAL IN-CAMERA IMAGE PROCESSING

摘要

The main object of the present invention is to provide a method for local in-camera image processing based on user controlled selective regions-of-interest (ROI). The present invention applies itself to the rapidly growing consumer digital camera segment. When a user clicks an image, many times unwanted artifacts dominate the objects of interest in a frame e.g. halo of a light in the background attracting more visual attention than the actual object of interest in the foreground. This unwanted effect might be eliminated, either automatically or by user"s discretion, using the current approach. The invention would work with devices having both, a digital camera and a touch screen interface. When a user is taking a picture he may use the touch screen to interactively manipulate the image locally, in-camera before actually taking the picture. Alternatively, the image may be processed with a saliency detector, which would identify the regions in the image likely to be visually important, and then the image may be processed incamera before taking the picture to enhance the important regions relative to the not so important ones. Thus the present invention provides a method for local in-camera image processing, characterized by the steps of: identifying regions-of-interest (ROI) in the image; processing for localized enhancement of the ROI portions by manipulating the image locally in-camera; and taking with the help of the camera a picture with the enhanced ROI.
