摘要： A method of processing an image comprises traversing each pixel of the image in a single pass over the image; applying an inverting function to each pixel; applying a recursive filter to each inverted pixel value, the filter having parameters which are derived from previously traversed pixel values of the image; and combining the pixel value with the filter parameter for the pixel to provide a pixel value for a processed image.

摘要： An image processing apparatus is arranged to process a first relatively underexposed and sharp image of a scene, and a second relatively well exposed and blurred image, nominally of the same scene, the first and second images being derived from respective image sources. The apparatus provides a portion of the relatively first underexposed image as an input signal to an adaptive filter; and a corresponding portion of the second relatively well exposed image as a desired signal to the adaptive filter. The adaptive filter produces an output signal from the input signal and the desired signal; and an image generator constructs a first filtered image from the output signal, relatively less blurred than the second image.

摘要： An estimated total camera motion between temporally proximate image frames is computed. A desired component of the estimated total camera motion is determined including distinguishing an undesired component of the estimated total camera motion, and including characterizing vector values of motion between the image frames. A counter is incremented for each pixel group having a summed luminance that is greater than a threshold. A counter may be decremented for pixels that are under a second threshold, or a zero bit may be applied to pixels below a single threshold. The threshold or thresholds is/are determined based on a dynamic luminance range of the sequence. The desired camera motion is computed including representing the vector values based on final values of counts for the image frames. A corrected image sequence is generated including the desired component of the estimated total camera motion, and excluding the undesired component.

摘要： A digital camera includes an optical system, a main image sensor and a camera motion sensor for estimating relative camera-object motion during image capture. A processor estimates camera motion based on information obtained by the camera motion photo-sensor while the camera is exposed to an image of a scene. The processor reduces or removes a motion blur effect from the main image permitting a processed version of the main image to be thereafter rendered.

摘要： A method of combining image data from multiple frames to enhance one or more parameters of digital image quality, e.g., video or still images, 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数字图像质量的一个或多个参数（例如，视频或静止图像）的方法包括以第一曝光持续时间获取第一图像，以及以第二曝光持续时间获取第二图像短于第一曝光持续时间，并且在获取第一图像时在刚刚之前，恰好在或重叠之后的时间，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。
