Abstract: Blurring is simulated in post-processing for captured images. A 3D image is received from a 3D camera, and depth information in the 3D image is used to determine the relative distances of objects in the image. One object is chosen as the subject of the image, and an additional object in the image is identified. Image blur is applied to the identified additional object based on the distance between the 3D camera and the subject object, the distance between the subject object and the additional object, and a virtual focal length and virtual f-number.

Abstract: In a motion detection device that detects motion from two frames of a video signal, a pattern matching detector determines pattern similarity between pixel blocks centered on a pixel of interest in the two frames to detect pattern motion. An edge detector detects edge presence and direction in a vicinity of the pixel of interest. A frame difference detector generates a smoothed frame difference signal for the pixel of interest. The smoothing is carried out within appropriate extents selected according to the detected pattern motion and edge direction. A motion information corrector generates motion information for the pixel of interest from the frame difference signal. Appropriate selection of the smoothing extent reduces motion detection mistakes. The motion information is useful in motion adaptive video signal processing.

Abstract: Described are embodiments of methods of obtaining three-dimensional (3D) surface data of an object scene such as an intra-oral cavity. For example, measured surfaces may include the enamel surface of teeth, the dentin substructure of teeth, gum tissue and various dental structures. The methods can also be applied in medical applications and other applications in which 3D measurement data are acquired with maneuverable 3D measurement devices. In certain embodiments, the measurement device is positioned and translated to enable 3D data to be acquired for a backbone 3D data set. Subsequent controlled motion of the measurement device enables additional 3D data to be acquired and accurately joined to the backbone 3D data set.

Abstract: A compressive imaging system modulates an incident light stream and senses the modulated light stream to obtain compressive measurements. The measurements are algorithmically processed to reconstruct a sequence of images. The image sequence is displayed. The system receives user input (through a user interface) representing a user command to set or change one or more visual performance factors such as image quality and frame rate. The system immediately adjusts the visual performance factors by adjusting one or more underlying system parameters/algorithms. Thus, the visual consequences of any inputs to the user interface become immediately apparent in the displayed sequence of images. The user may therefore intuitively learn how to operate the user interface simply by making trial inputs and observing their effects in the displayed image sequence. The user interface may include one or more mechanical input devices and/or one or more graphical user interface (GUI) elements.

Abstract: In one aspect, the invention provides an imaging system including an optical system adapted to receive light from a field of view and direct the received light to two image planes. A fixed image detector is optically coupled to one of the image planes to detect at least a portion of the received light and generate image data corresponding to at least a portion of the field of view. A movable (e.g., rotatable) image detector is optically coupled to the other image plane to sample the received light at different locations thereof to generate another set of image data at a higher resolution than the image data obtained by the fixed detector. The system can include a processor for receiving the two sets of image data to generate two images of the field of view.

Abstract: In an electronic endoscope system, a changed-area detector detects a changed area from an image captured by an endoscope, the changed area having different features from other area of the captured image. A mask data produce produces mask data based on the detected changed area, the mask data allocating an image processing parameter to each pixel of the captured image such that the changed area is processed in a different way from the other area. An image processor processes the captured image according to the mask data. Thus, an image area corresponding to an artificial object like a surgical tool may be detected as the changed area and excluded from unnecessary image processing.

Abstract: The present invention relates to an apparatus and method for correcting synchronization errors, which involve correcting synchronization errors occurring between video signals and audio signals when multiple videos are combined. The apparatus and method of the present invention involve: storing synchronization errors between an initial video signal and an initial audio signal of each video to be combined when combining different pieces of video content; and combining multiple pieces of video content such that the initial synchronization error which is set to synchronize existing video signals with existing audio signals can be maintained when combining multiple pieces of video content. The apparatus and method of the present invention enable the drawbacks of conventional techniques, i.e. that video signals and audio signals are uniformly combined, errors are corrected, and thus the video signals and the audio signals are unsynchronized which results in unnatural video, to be overcome.

Abstract: Sampled data is packaged in checkerboard format for encoding and decoding. The sampled data may be quincunx sampled multi-image video data (e.g., 3D video or a multi-program stream), and the data may also be divided into sub-images of each image which are then multiplexed, or interleaved, in frames of a video stream to be encoded and then decoded using a standardized video encoder. A system for viewing may utilize a standard video decoder and a formatting device that de-interleaves the decoded sub-images of each frame reformats the images for a display device. A 3D video may be encoded using a most advantageous interleaving format such that a preferred quality and compression ratio is reached. In one embodiment, the invention includes a display device that accepts data in multiple formats.
