Image capturing systems are disclosed. In one aspect, an image capturing system includes an image capture device and at least two light-deflecting devices associated with the image capture device. The image capture device is capable of capturing different perspective views of objects in a scene. The at least two light-deflecting devices are positioned between the image capture device and the scene. The at least two light-deflecting devices are capable of being oriented in at least two different orientations to re-direct the path of light rays from the objects in the scene to the associated image capture device, enabling the capture of successive perspective views of the scene.

Image viewing systems are disclosed. In one aspect, an image viewing system includes a screen (108, 208, 302, 402, 502, 602, 808) and a projection system (304) that includes at least one video projector (310, 410, 510, 610, 810), and at least two mirrors (311, 411, 511, 611, 811) associated with each video projector (310, 410, 510, 610, 810). The projection system (304) projects different perspective views of images onto the screen (108, 208, 302, 402, 502, 602, 808). The at least two mirrors are oriented in at least two different orientations to redirect the path of light rays from the associated video projector (310, 410, 510, 610, 810) to the screen (108, 208, 302, 402, 502, 602, 808), enabling a viewer looking at the screen (108, 208, 302, 402, 502, 602, 808) to view successive views of each image.

A method and system for interfacing a digital device with an interactive display surface (IDS) is presented. The IDS detects the digital device when it is brought into proximity, and attempts to identify the device. The IDS communicates with the device, and displays interactive representations of information stored on the device.

A method for reducing view-dependent artifacts in a multi-projector system includes the steps of measuring, from multiple viewpoints, projection characteristics of an image projected by a multi-projector system, estimating view-dependent projection parameters that can reduce view-dependent artifacts, and computing rendering parameters for each projector so as to reduce the view-dependent artifacts.

A method for tone mapping a digital image comprised of a plurality of high bit depth intensity values in linear space is disclosed. First, a plurality of liner intensity values are mapped from the linear space to a non-linear space (402). Then a left and a right boundary interval value are determined in the linear space for each of the plurality of high bit depth intensity value (404). A dither pattern is then overlaid onto the plurality of high bit depth intensity values in linear space (406). For each one of the plurality of high bit depth intensity values in linear space, one of the boundary interval values is selected, based on the current high bit depth intensity value, the left and right boundary interval values for the current pixel, and the dither pattern value overlaid onto the current pixel (408). Each of the selected boundary interval values are mapped into a lower bit depth non-linear space (410). And then the mapped selected boundary interval values are stored onto a computer readable medium.
摘要:
A reference set of image features is determined from an electronic data file specifying a reference image in a reference coordinate space. Rendering information describing a physical rendering of the reference image is ascertained. Calibration-enabling data is derived from the reference set of the image features and the ascertained rendering information. The calibration-enabling data is provided to calibrate an imaging system. The calibration-enabling data may be stored. The imaging system may capture an image of the physical rendering of the reference image in relation to a capture coordinate space. An extracted set of image features may be extracted from the captured image. Respective ones of the image features in the reference and extracted sets may be matched. The imaging system may be calibrated based on matched ones of the image features and the rendering information.

A system for providing advertising content includes a public display; a database configured to store the advertising content; and a central processing element configured to dynamically interact with participants in an activity and present the advertising content in connection with information about the activity on the public display. A method of providing advertising content includes conducting an activity involving participants; receiving input regarding the participants engaged in the activity; and displaying advertising content from a database concurrently with information regarding the activity.

An image display system including an image generator configured to generate display information for at least four display primaries by applying distortion information to an input signal, where the distortion information configured to compensate for variations in human cone responses, and a display device including the at least four display primaries and configured to display a first image with the at least four display primaries using the display information such that distortion from the distortion information appears in a second image captured by an image capture device to include the first image and such that substantially all human observers do not see the distortion in the first image is provided.
摘要:
An apparatus and method for distributing representative images of a plurality of data objects within a database within a partitioned three-dimensional graphical environment is described. According to the apparatus and method an environment is divided into areas bounded by partitions, and groups of representative images are distributed and displayed upon these partitions. In general, distribution of the representative images is achieved by determining weight factors for each partition bounding a given area and determining weight factors for representative images that are to be displayed within the areas upon the partitions and then distributing the images dependent on the comparison of the image weight factors to partition weight factors.
