摘要： A system and method of obtaining a reconstructed digital image of an image that is projected, displayed, or printed on a surface by capturing a single digital image of the surface is described. According to the system and method, at least three illumination marks are projected onto the surface. The illumination marks have a particular detectable characteristic. An image capture device captures a single image of the surface including the illumination marks to obtain captured image data. The location and the pixel values corresponding to the illumination marks are detected dependent on the particular characteristic of the illumination mark pixels in the captured image data. The locations of the illumination marks are then used to correct for distortion of the image and surface in the captured image data to generate an undistorted digital image of the image on the surface. The illumination mark pixel values are replaced within undistorted digital image with estimated pixel values that are determined using neighboring non-illumination mark pixel values.

摘要： Using a joint video and still image pipeline technology, a network (230) may be deployed through the Internet so that a user (322) may be deployed through the Internet so that a user (322) may acquire a remote high resolution photograph (110) using a low resolution video (120) streamed from a remote camera (240) as a view-finder. The remote camera (240) may enable the user (322) to exercise control from a remote device (220, 222) through the network (230) or other communication channels. A network server may store the video (120) and the high resolution photograph (110), and either sends the video (120) and the high resolution photograph (110) to the user (322) upon payment or posts the video (120) and the high resolution photograph (110) on a web page.

摘要： A digital stereo camera (10) using a single sensor array (20) to take both left and right images for stereo (three-dimensional) image capture. In one embodiment, a micro-lens array (16) is used to focus, at a first instant in time, light ("left light") from a left lens system (12) onto a sensor array (20) for left image capture. Then, the micro-lens array (16) is moved to focus light ("right light") from a right lens system (14) onto the sensor array (20) for right image capture. In another embodiment, a portion of the left light (the portion having a first polarized direction) and a portion of the right light (the portion having a second polarized direction) are directed to a sensor array (52); the second polarized direction being orthogonal to the first polarized direction. To capture the left image, a polarization filter (56) is used to allow the left light (having the first polarized direction) to pass toward the sensor array (52) while preventing the right light (having the second polarized direction) from reaching the sensor array (52). To capture the right image, polarization direction of the polarization filter (58) is switched to allow only the right light (having the second polarized direction) to reach the sensor array (52).
