20160119561 | METHOD AND APPARATUS FOR HANDLING A DEFECT OBJECT IN AN IMAGE - A method and an apparatus for handling a defect object in an image. A light field information retrieving unit retrieves a light field capture of the image. A view generator generates a center view and two or more side views from the light field capture. A defect determining unit then determines a defect object in the image through a comparison of the center view and the two or more side views. | 04-28-2016 |
20160134812 | IMAGE STABILIZATION TECHNIQUES FOR VIDEO SURVEILLANCE SYSTEMS - A behavioral recognition system may include both a computer vision engine and a machine learning engine configured to observe and learn patterns of behavior in video data. Certain embodiments may provide image stabilization of a video stream obtained from a camera. An image stabilization module in the behavioral recognition system obtains a reference image from the video stream. The image stabilization module identifies alignment regions within the reference image based on the regions of the image that are dense with features. Upon determining that the tracked features of a current image is out of alignment with the reference image, the image stabilization module uses the most feature dense alignment region to estimate an affine transformation matrix to apply to the entire current image to warp the image into proper alignment. | 05-12-2016 |
20160150157 | AUTO CALIBRATION METHOD AND OIS CAMERA USING THE SAME - An auto calibration method and an optical image stabilizer (OIS) camera using the same are provided. The auto calibration method includes removing a DC offset of a gyroscope. A vibrator signal applied by operating a vibrator, and an actual measurement value of the gyroscope is obtained using the applied vibrator signal. A first gain value for compensating for sensitivity of the gyroscope is calculated using the vibrator signal and the actual measurement value of the gyroscope, and an actuator is operated. A displacement of a pixel actually moving on an image is moved under an operation of the actuator. A second gain value for controlling a sensitivity variation of the actuator is calculated based on the displacement of the actually moving pixel. Accordingly, it is possible to reduce processing time and to ensure high performance. | 05-26-2016 |
20160165100 | IMAGE PICKUP APPARATUS AND PROCESSING METHOD FOR RESULT OF IMAGE PICKUP - The present invention is applied to an image pickup apparatus for which, for example, a CMOS solid-state image pickup element is used. One screen image is divided into a plurality of blocks, and a motion is detected for each of the blocks to control the exposure time of the block. | 06-09-2016 |
