  • Publication number: 20100157070
    Abstract: Real-time image stabilization using computationally efficient corner detection and correspondence is provided. The real-time image stabilization performs a scene learning process on a first frame of an input video to obtain reference features and a detection threshold value. The presence of jitter is determined in a current frame of the input video by comparing features of the current frame against the reference features using the detection threshold value. If the current frame is found to be unstable, corner points are obtained from the current frame. The obtained corner points are matched against reference corner points of the reference features. If the number of matched corner points is not less than a match point threshold value, the current frame is modeled using random sample consensus. The current frame is corrected to compensate for the jitter based on the results of the modeling.

  • Patent number: 7697034
    Abstract: When a blurring correction is performed when shooting a moving image, a digital camera performs blurring correction on the picked up frames and successively records the frames. Then, when generating a moving image file, the digital camera records information stating that the blurring correction has been performed in the header of the file, thereby preventing the blurring correction from being performed again when the moving image is played back. In addition, in the case that only the blurring detection is performed when shooting the moving image, the digital camera detects the blurring in the frame, correlates the detected blurring amount in the frame with the frame, and successively records the blurring amounts. Then, when generating the moving image file, the digital camera records information stating that the blurring detection has been performed in the header of the file.

    Abstract: A video camera includes an image sensor which repeatedly outputs an object scene image produced on an imaging surface by an exposure operation of a focal-plane electronic shutter system in a raster scanning manner. A post-processing circuit extracts a partial object scene image belonging to an extraction area, out of the object scene image outputted from the image sensor. A moving image based on the extracted partial object scene image is displayed on an LCD monitor by an LCD driver. A motion detecting circuit detects motion of the imaging surface in a direction orthogonal to an optical axis. A position of the extraction area is changed by a CPU so that the motion detected by the motion detecting circuit is compensated. The CPU also changes a shape of the extraction area so that a focal plane distortion is restrained, based on the motion detected by the motion detecting circuit.

    Abstract: A method for estimating egomotion of a camera mounted on a vehicle that uses infra-red images is disclosed, comprising the steps of (a) receiving a pair of frames from a plurality of frames from the camera, the first frame being assigned to a previous frame and an anchor frame and the second frame being assigned to a current frame; (b) extracting features from the previous frame and the current frame; (c) finding correspondances between extracted features from the previous frame and the current frame; and (d) estimating the relative pose of the camera by minimizing reprojection errors from the correspondences to the anchor frame.

  • Patent number: 7576780
    Abstract: A signal processor 12 acquires a second signal obtained by detecting a first signal, as a signal of the real world, having a first dimension. The second signal is of a second dimension lower than the first dimension and has distortion relative to the first signal. The signal processor 12 performs signal processing which is based on the second signal to generate a third signal alleviated in distortion as compared to the second signal.

  • Publication number: 20090185041
    Abstract: Provided are an apparatus and method of obtaining a high-quality image by efficiently processing an image obtained at low-light levels. The image obtaining apparatus comprises a sensor which detects a pixel array value by using a color filter including color pixels for obtaining a color image and a reference pixel for obtaining a reference image used for hand-trembling function estimation; an exposure controller which controls exposure times of the color pixels and the reference pixel; and an image generator which generates a long-exposure color image signal and a short-exposure reference image signal from the detected pixel array value, the long-exposure color image signal and the short-exposure reference image signal being aligned with each other. Accordingly, accurate estimation of the hand-trembling function is possible, thereby enabling the high-quality color image restoration.

  • Patent number: 7564482
    Abstract: An image capturing device is adapted to capture an object image and to generate an image data. Each of a plurality of image capturers is adapted to perform an image capturing of a part of the object image and to generate a partial image data which constitutes a part of the image data based on the part of the object image. Each of the image capturers has an optical axis. A detector is operable to detect movement of each of the image capturers in a direction perpendicular to the optical axis during the image capturing and to generate movement data based on the detected movement, for each of the image capturers. A processor is operable to correct the partial image data so as to compensate the movement during the image capturing based on the movement data.

    Abstract: A system for detecting movement of a camera having a variable optical element (2). The system comprises a beam splitter (7) for capturing a part of the light traversing the lens and for splitting into at least a pair of light beams (8, 10). For each of the light beams the system comprises a light sensor (9, 11). Each sensor is provided with a grating (9g, 11g) in the light path for each of the light sensors. The gratings of the sensors have substantially the same pitch, but are positioned with a shift (S) that in respect of the light beam impinging on said sensor differ. The system further comprising a comparator (5) for comparing time shifted signals from the light sensors.

  • Patent number: 7558405
    Abstract: 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.

  • Publication number: 20090147090
    Abstract: There is provided an image processing device that enables acquisition of a superior image even when camera movement arose. A digital camera has an angular velocity sensor for detecting amounts of camera movement arising during photographing. A control parameter computation section computes, from a result of detection performed by the angular velocity sensor, an edge enhancement coefficient by means of which a decrease arises in a degree of enhancement in a band where the signal component of the original image obtained in an ideal no-camera-movement, noiseless state has decreased for reasons of the camera movement. Moreover, there is also computed a quantization table by means of which an increase arises in a quantization value in a band where the signal component of the original image has decreased.
