    摘要: The specification and drawings present a new method, system, apparatus and software product for constructing by an electronic device an image panorama from a plurality of images based on their visual quality. The same portion of a panoramic image scene is typically captured on multiple neighborhood video frames from which one can choose the best visual representation to be pasted into the panorama. Constructing the image panorama from the plurality of captured images can comprise the following steps: a) evaluating image quality of K consecutive frames out of the captured plurality of images using a predetermined criterion, b) selecting one image out of the evaluated K frames with the best image quality using a predetermined rule, and c) appending the selected frame to previously selected frames for constructing the image panorama. On-line and off-line implementations are possible.

    摘要: A method of improving image quality of a digital image is provided. In particular, the motion blur in an image taken in a long exposure time is reduced by dividing the exposure time into several shorter periods and capturing a series of images in those shorter periods. Among the images, one reference image is selected and the remaining images are registered in reference to the reference image by image warping, for example. After identifying the pixels in each of the remaining images and the corresponding pixels in the reference image, a weighting factor is assigned to each of the pixels in the remaining images based on the similarity in the pixel values between the remaining images and reference image. A weight average operation is carried out to sum the corresponding pixels in the reference and the remaining images to generate the final image.

    摘要: An improved system and method for capturing an image using a camera or a camera module. In the present invention, the number of image shots taken, as well as the integration time of each image shot, are controlled based upon knowledge about the existence or absence of camera motion. Whenever a motion is detected above a predetermined motion threshold, the integration phase of the current image shot ends, and the integration of the next image shot begins. The present invention therefore adapts to the actual camera motion during exposure. If there is no camera motion, a single, long exposed image shot is captured. If there is camera motion, the total exposure time is divided between multiple shots in accordance with the degree of camera motion.

    摘要: For applying a motion filter of a video stabilization system to a sequence of video frames, an estimate of a motion in the current video frame compared to a first video frame of the sequence of video frames is received. Based on the received motion estimate and on at least one state variable of the motion filter, a correction value for the motion in the current video frame is computed. The at least one state variable is updated in the computation. In case the computed correction value exceeds a system constraint of the video stabilization system, the at least one state variable is adjusted in accordance with an extent by which the system constraint is exceeded. The correction value is then recomputed based on the motion estimate and on the adjusted state variable.

    摘要: Methods and systems are provided for adjusting the contrast and intensity of digital images. Digital images may be processed by first creating a histogram that identifies the intensity of components of the digital image. A transformation function is then computed using the histogram. The transformation function can be used to adjust the intensity of a low light portion of the digital image and is applied to individual color components of the digital image. Finally, the contrast of a portion of the digital image other than the low light portion of the digital image is adjusted.
