20080259203 | Systems And Methods For Identifying Camera Sensors - Systems and methods for identifying camera sensors are disclosed. In an exemplary implementation, a method for identifying camera sensors may include exposing a plurality of camera sensors at a time T1, each of the plurality of camera sensors having an array of pixels, and storing the location of unique pixels within the array of pixels for each of the camera sensors exposed at time T1 in a data structure. The method may also include exposing one of the plurality of camera sensors at time T2, and comparing the unique pixels within the array of pixels for the one camera sensor exposed at time T2 with locations of unique pixels of each of the camera sensors exposed at time T1. The one camera sensor may be identified based on the comparing step. | 10-23-2008 |
20110025878 | Determining the Illuminant in a Captured Scene - A method for determining an illuminant in a scene includes, applying, to sampled outputs of a sensor array used to capture the scene, a plurality of color-correction profiles, wherein each color-correction profile corresponds to a particular illuminant, thereby forming a plurality of color-corrected sampled outputs. The method further includes identifying the illuminant in the scene as corresponding to the color-corrected sampled output having the least color variance. | 02-03-2011 |
20110316876 | PROCESSING IMAGES OF A DISPLAY - An apparatus for processing images of a display includes an image sequence receiving module adapted to receive a first sequence of images of the display. The first sequence of images includes at least one image corrupted due to partial refreshing of the display. The apparatus also includes an image processing module operable to process the first sequence of images on an image by image basis to eliminate the at least one corrupted image from at least one of the first sequence of images and a second sequence of images captured subsequent to the first sequence of images. | 12-29-2011 |
20120069203 | GENERATING A STABILIZED VIDEO SEQUENCE BASED ON MOTION SENSOR DATA - A machine-implemented method of generating a stabilized video sequence includes receiving an input video sequence captured by an image capture device. The input video sequence includes a plurality of pairs of successive frames. Motion sensor data indicative of motion of the image capture device while the input video sequence was being captured is received. A set of matching features for each pair of successive frames is identified. Global motion features are identified in each set of matching features and qualified based on the motion sensor data. The global motion features are indicative of movement of the image capture device. A stabilized video sequence is generated based on the input video sequence and the identified global motion features. | 03-22-2012 |
20120120282 | Reducing Temporal Aliasing - Camera systems and methods to reduce temporal aliasing are disclosed. In an exemplary embodiment the method may include selecting exposure times for each frame based on lighting conditions and a frame rate for frame capture. The method may also include capturing a plurality of exposures for each frame based on the selected exposure times. The method may also include integrating the plurality of exposures for each frame. | 05-17-2012 |
20140253790 | FILTER WITH FIRST POLARIZED PORTION AND A SECOND POLARIZED PORTION - A portable device including a light source, an image capture component with an image sensor, a filter with a first polarized portion and a second polarized portion, a mechanism to reposition the filter to overlap the light source with the first polarized portion of the filter and overlap the image sensor with the second polarized portion of the filter, and a controller to capture visual media with the image capture component. | 09-11-2014 |
20140375681 | ACTIVE BINOCULAR ALIGNMENT FOR NEAR EYE DISPLAYS - A system and method are disclosed for detecting angular displacement of a display element relative to a reference position on a head mounted display device for presenting a mixed reality or virtual reality experience. Once the displacement is detected, it may be corrected for to maintain the proper binocular disparity of virtual images displayed to the left and right display elements of the head mounted display device. In one example, the detection system uses an optical assembly including collimated LEDs and a camera which together are insensitive to linear displacement. Such a system provides a true measure of angular displacement of one or both display elements on the head mounted display device. | 12-25-2014 |
20140375790 | EYE-TRACKING SYSTEM FOR HEAD-MOUNTED DISPLAY - Embodiments are disclosed for a see-through head-mounted display system. In one embodiment, the see-through head-mounted display system comprises a freeform prism, and a display device configured to emit display light through the freeform prism to an eye of a user. The see-through head-mounted display system may also comprise an imaging device having an entrance pupil positioned at a back focal plane of the freeform prism, the imaging device configured to receive gaze-detection light reflected from the eye and directed through the freeform prism. | 12-25-2014 |
