| 20130182077 | ENHANCED CONTRAST FOR OBJECT DETECTION AND CHARACTERIZATION BY OPTICAL IMAGING - Enhanced contrast between an object of interest and background surfaces visible in an image is provided using controlled lighting directed at the object. Exploiting the falloff of light intensity with distance, a light source (or multiple light sources), such as an infrared light source, can be positioned near one or more cameras to shine light onto the object while the camera(s) capture images. The captured images can be analyzed to distinguish object pixels from background pixels. | 07-18-2013 |
| 20130182079 | MOTION CAPTURE USING CROSS-SECTIONS OF AN OBJECT - An object's position and/or motion in three-dimensional space can be captured. For example, a silhouette of an object as seen from a vantage point can be used to define tangent lines to the object in various planes (“slices”). From the tangent lines, the cross section of the object is approximated using a simple closed curve (e.g., an ellipse). Alternatively, locations of points on an object's surface in a particular slice can also be determined directly, and the object's cross-section in the slice can be approximated by fitting a simple closed curve to the points. Positions and cross sections determined for different slices can be correlated to construct a 3D model of the object, including its position and shape. A succession of images can be analyzed to capture motion of the object. | 07-18-2013 |

This halves the integration time but also halves the resolution of the sensor. The reduction is tolerable for motion characterization as long as sufficient image resolution remains. Accordingly, in one embodiment, an image sensor operated in an interlaced fashion is first exposed to a scene under a first form of illumination (e.g., narrowband illumination), and a first set of alternating (horizontal or vertical) lines constituting half of the pixels is read out of the array; the sensor is then exposed to the same scene under a second form of illumination (e.g., existing ambient illumination with the illumination source turned off), and a second set of alternating lines, representing the other half of the pixel array, is read out. The two images are compared and noise removed from the image obtained under narrowband illumination. As this occurs, the image sensor is capturing the next image under the first form of illumination, and the process continues. | 05-08-2014 |

This capability allows the user to execute intuitive gestures involving contact with a surface. For example, in low-light situations where free-form gestures cannot be recognized optically with a sufficient degree of reliability, a device implementing the invention may switch to a touch mode in which touch gestures are recognized. In implementations, two contact microphones or other vibratory or acoustical sensors, that are coupled to an optical motion-capture and are in contact with a surface that a user touches, are monitored. When the contact microphones detect audio signals (or other vibrational phenomena) generated by contact of an object with the surface that the user touches, a position of the object traveling across and in contact with the surface is tracked. | 07-10-2014 |

For example, if the user's hand is being tracked for gestures, the closer the hand gets to another object, the tighter the frame can become—i.e., the more the camera can zoom in so that the hand and the other object occupy most of the frame. The camera can also be reoriented so that the hand and the other object remain in the center of the field of view. The distance between two objects in a camera's field of view can be determined and a parameter of a motion-capture system adjusted based thereon. In particular, the pan and/or zoom levels of the camera may be adjusted in accordance with the distance. | 08-28-2014 |

In some examples a transparency imperfection in a window through which a camera receives light can be detected and a message sent to a user as to the presence of a light-blocking or light-distorting substance or particle. A system can control illumination while imaging an object in space using a light source mounted to a support structure so a camera captures an image of the illuminated object. Direct illumination of the camera by light from the light source can be prevented such as by blocking the light or using a light-transmissive window adjacent the camera to reject light transmitted directly from the light source. | 09-18-2014 |

| 20150341618 | CALIBRATION OF MULTI-CAMERA DEVICES USING REFLECTIONS THEREOF - The technology disclosed can provide capabilities such as calibrating an imaging device based on images taken by device cameras of reflections of the device itself. Implementations exploit device components that are easily recognizable in the images, such as one or more light-emitting devices (LEDs) or other light sources to eliminate the need for specialized calibration hardware and can be accomplished, instead, with hardware readily available to a user of the device—the device itself and a reflecting surface, such as a computer screen. The user may hold the device near the screen under varying orientations and capture a series of images of the reflection with the device's cameras. These images are analyzed to determine camera parameters based on the known positions of the light sources. If the positions of the light sources themselves are subject to errors requiring calibration, they may be solved for as unknowns in the analysis. | 11-26-2015 |
