摘要： Disclosed is a technology related to a video surveillance system using a camera capable of a pan-tilt-zoom operation. The video surveillance system includes a pan-tilt-zoom camera for photographing a surveillance region, and a display device for outputting an image of the pan-tilt-zoom camera. The pan-tilt-zoom camera provides a fisheye image representing an entire surveillance region onto a first region of the display device, calculates driving parameters of the pan-tilt-zoom camera on the basis of location information of a portion selected from the fisheye image, moves the pan-tilt-zoom camera to a location of the selected portion according to the driving parameters, and provides a monitoring image of the selected portion photographed by the pan-tilt-zoom camera onto a second region of the display device. According to the present invention, the pan-tilt-zoom camera is allowed to be intuitively and rapidly controlled using the fisheye image and to rapidly generate a fisheye image.

摘要： A fisheye image transformation algorithm based on virtual spheres is provided, comprising: defining a real camera coordinate system O-XYZ and a virtual camera coordinate system O2-X2Y2Z2, wherein a small virtual sphere centered at O with a radius of 1 and a large virtual sphere centered at O2 with a radius of n are defined, the small sphere is internally tangent to the large sphere; transforming a fisheye image to 3D unit vectors in the real camera coordinate system, transforming the 3D unit vectors between the real camera coordinate system and the virtual camera coordinate system according to a relative position between two spheres, and conducting conventional projection of the 3D unit vectors in the virtual camera coordinate system to generate the transformed image; and reducing the line curvature of the transformed image to a certain degree by adjusting the HFOV angle or the VFOV angle of the virtual camera.

摘要： Foveated rendering for rendering an image uses a ray tracing technique to process graphics data for a region of interest of the image, and a rasterisation technique is used to process graphics data for other regions of the image. A rendered image can be formed using the processed graphics data for the region of interest of the image and the processed graphics data for the other regions of the image. The region of interest may correspond to a foveal region of the image. Ray tracing naturally provides high detail and photo-realistic rendering, which human vision is particularly sensitive to in the foveal region; whereas rasterisation techniques are suited for providing temporal smoothing and anti-aliasing in a simple manner, and is therefore suited for use in the regions of the image that a user will see in the periphery of their vision.

摘要： Methods and apparatus for multi-encoder processing of high resolution content. In one embodiment, the method includes capturing high resolution imaging content; splitting up the captured high resolution imaging content into respective portions; feeding the split up portions to respective imaging encoders; packing encoded content from the respective imaging encoders into an A/V container; and storing and/or transmitting the A/V container. In another embodiment, the method includes retrieving and/or receiving an A/V container; splitting up the retrieved and/or received A/V container into respective portions; feeding the split up portions to respective imaging decoders; stitching the decoded imaging portions into a common imaging portion; and storing and/or displaying at least a portion of the common imaging portion.

摘要： A method for automatically generating, in real-time, for display on a display, a simplified network layout from an initial network layout including one or more lines each connecting a plurality of nodes. Graph information is provided indicating vertices representing geographic positions of the nodes and edges representing connections between the nodes. The nodes are repositioned to optimize an objective function based on readability of the simplified network layout. Nodes and edges are discretized using interpolation to align a plurality of the nodes and connect the aligned nodes using simplified k-linear segments, where k-linear segments are parallel to one of k equidistant orientations whose angles are multiples of 180/k degrees, with k larger or equal to two. The simplified network layout is provided for a display.

摘要： A method for processing an image is provided, in which a circular omnidirectional image is received. The circular omnidirectional image is displayed on a display. A first rectangular image representing a first part of the circular omnidirectional image is generated in response to a first user input received via the display on the circular omnidirectional image. The first rectangular image is superimposed on the circular omnidirectional image.

摘要： A method for processing an image is provided in which an omnidirectional image is received. The omnidirectional image is displayed on a display. Two panoramic images are generated based on the omnidirectional image by correcting distortion of the omnidirectional image. The two panoramic images are displayed on the display in response to a user input. Both of the two panoramic images are scrolled in response to a user input conducted on one of the two panoramic images displayed on the display.

摘要： An imaging apparatus that starts connecting processing at a synthesizing position in an early stage is provided. The imaging apparatus includes: a first imaging element that images a first imaging range, a second imaging element that images a second imaging range of which one part overlaps with the first imaging range, and a synthesizing unit that synthesizes an image corresponding to an imaging range wider than the first imaging range or the second imaging range, based on pixel data groups output by the first imaging element and the second imaging element, wherein the first imaging element and the second imaging element output pixel data corresponding to a position at which the first imaging range and the second imaging range overlap each other, to a synthesizing unit prior to other pixel data.
