One or more characteristics of the first image are determined. One or more corrective processes are identified including red eye correction that can be beneficially applied to the first image according to the one or more characteristics. The one or more corrective processes are applied to the first image.

摘要： A method of combining image data from multiple frames to enhance one or more parameters of video image quality includes acquiring a first image at a first exposure duration, as well as acquiring a second image at a second exposure duration shorter than the first exposure duration and at a time just before, just after or overlapping in time with acquiring the first image, such that the first and second images include approximately a same first scene. In this way, the second image is relatively sharp and under-exposed, while the first image is relatively well-exposed and less sharp than the second image. Brightness and/or color information are extracted from the first image and applied to the second image to generate an enhanced version of the second image.
摘要翻译：一种组合来自多个帧的图像数据以增强视频图像质量的一个或多个参数的方法包括以第一曝光持续时间获取第一图像，以及以比第一曝光持续时间短的第二曝光持续时间获取第二图像，并且在获取第一图像之前，恰好在或之后重叠的时间，使得第一和第二图像包括大致相同的第一场景。以这种方式，第二图像相对较锋利且曝光不足，而第一图像相对曝光较好，并且不如第二图像那样锐利。从第一图像提取亮度和/或颜色信息并将其应用于第二图像以生成第二图像的增强版本。

摘要： A technique involves distinguishing between foreground and background regions of a digital image of a scene. First and second images are captured of nominally a same scene. The first image is a relatively high resolution image taken with the foreground more in focus than the background, while the second image is a relatively low resolution reference image taken with the background more in focus than the foreground. Regions of the captured images are assigned as foreground or background. In accordance with the assigning, one or more processed images are rendered based on the first image or the second image, or both.

摘要： A method automatically corrects dust artifact within image acquired by a system including a digital acquisition device including a lens assembly and a translucent lens cap. Multiple original digital images are acquired with the digital acquisition device. Probabilities that certain pixels correspond to dust artifact regions within the images are determined based at least in part on a comparison of suspected dust artifact regions within two or more of the images. Probable dust artifact regions are associated with extracted parameter values relating to the lens assembly when the images were acquired, A statistical dust map is formed including mapped dust regions based on the determining and associating. Pixels corresponding to correlated dust artifact regions are corrected within further digitally-acquired images based on the associated statistical dust map.

摘要： A method for red-eye detection in an acquired digital image acquiring one or more preview or other reference images without a flash. Any red regions that exist within the one or more reference images are determined. A main image is acquired with a flash of approximately a same scene as the one or more reference images. The main image is analyzed to determine any candidate red eye defect regions that exist within the main image. Any red regions determined to exist within the one or more reference images are compared with any candidate red eye defect regions determined to exist within the main image. Any candidate red eye defect regions within the main image corresponding to red regions determined also to exist within the one or more reference images are removed as candidate red eye defect regions.

摘要： A digital camera has an integral flash and stores and displays a digital image. Under certain conditions, a flash photograph taken with the camera may result in a red-eye phenomenon due to a reflection within an eye of a subject of the photograph. A digital apparatus has a red-eye filter which analyzes at least one partial face region identified within the digital image for the red-eye phenomenon and modifies the image to eliminate the red-eye phenomenon by changing the red area to black. The modification of the image is enabled when a photograph is taken under conditions indicative of the red-eye phenomenon. The modification is subject to anti-falsing analysis which further examines the area around the red-eye area for indicia of the eye of the subject. The detection and correction can be optimized for performance and quality by operating on subsample versions of the image when appropriate.
摘要翻译：数码相机具有整体闪光灯，并存储和显示数字图像。在某些条件下，用相机拍摄的闪光照片可能会由于照片中的对象的眼睛内的反射而导致红眼现象。数字设备具有红眼滤光器，其分析在数字图像中识别的至少一个部分面部区域用于红眼现象，并通过将红色区域改变为黑色来修改图像以消除红眼现象。当在指示红眼现象的条件下拍摄照片时，能够进行图像的修改。该修改受到反假冒分析的限制，该分析进一步检查红眼区域周围区域的标记对象的眼睛。通过在适当的情况下对图像的子样本版本进行操作，可以对性能和质量进行优化。
