Abstract: An imaging device includes a varifocal lens and an imaging sensor which outputs a signal corresponding to light. The imaging sensor includes a photoelectric conversion unit which converts light into an electric charge, electric charge reading regions, transfer control electrodes, a gate control circuit which sequentially applies control signals to the transfer control electrodes to correspond to the position of the focal point of the varifocal lens, and a reading circuit which outputs a signal corresponding to the amount of the electric charge transferred to the electric charge reading regions. The gate control circuit repeats an operation of outputting each of the control signals when the position of the focal point is located in the focal ranges during a frame period.
Abstract: A system for capturing aerial images, the system comprising at least one camera unit, the camera unit comprising at least one overview camera, a plurality of detail cameras, and a frame for holding the cameras, each detail camera having a longer focal length than the at least one overview camera, each detail camera mounted at a different angle laterally so that the fields of view of the detail cameras overlap to form an extended lateral field of view.

Abstract: The present invention calibrates interior orientation parameters (IOP) and exterior orientation parameters (EOP). With the calibrated IOPs and EOPs, a remotely controlled camera can quickly obtains corresponding IOPs and EOPs no matter on panning, tilting or zooming. Thus, the remotely controlled camera obtains accuracies on imaging and measuring and obtains wide applications.

Abstract: An imaging system includes an offset focal array including a plurality of photosensitive elements disposed at different focal lengths from at least one lens to output an image simulating an orthogonal view of an oblique coverage area. In further embodiments, the photosensitive elements are arranged in layers positioned substantially equal to the focal lengths of one or more focusing lenses.
Abstract: A digital data searching apparatus is provided with a data storage for storing digital data and first and second attribute data representing conditions on which the respective digital data were created; a first classifying device for classifying the digital data into i sets based on the first attribute data; a second classifying device for classifying the digital data into j sets based on the second attribute data; a first selecting device for selecting one set from the i sets upon receiving an input from outside; a second selecting device for selecting one set from the j sets upon receiving an input from outside; an extracting device for calculating a product set of the set selected by the first selecting device and the set selected by the second selecting device, and a display controller for displaying the digital data included in the product set on a display device. Digital data satisfying a specified condition can be efficiently searched from a plurality of digital data.
Abstract: Portable virtual reality is disclosed. A digital camera captures an input video stream comprising video frames that carry information about a surrounding environment limited by a field of view of the camera. The input video stream is processed by a handheld computer coupled to the camera. Parameters that define a rendered scene of a virtual environment are adjusted based upon motion parameters extracted from the input video stream by the handheld computer during the processing.
