Camera-based tracking and position determination for sporting events
ActiveUS20100026809A1Good playerGood ball position trackingTelevision system detailsCharacter and pattern recognitionDigital signal processingAccelerometer
Position information of equipment at an event, such as a ball, one or more players, or other items in a game or sporting event, is used in selecting camera, camera shot type, camera angle, audio signals, and / or other output data for providing a multimedia presentation of the event to a viewer. The position information is used to determine the desired viewer perspective. A network of feedback robotically controlled Pan-Tilt-Zoom (PTZ), manually controlled cameras and stationary cameras work together with interpolation techniques to create a 2D video signal. The position information may also be used to access gaming rules and assist officiating of the event. The position information may be obtained through a transceiver(s), accelerometer(s), transponder(s), and / or RADAR detectable element(s) fitted into the ball, apparel or equipment of players, the players themselves, or other playing equipment associated with the game or sporting event. Other positioning methods that can be used include infrared video-based tracking systems, SONAR positioning system(s), LIDAR positioning systems, and digital signal processing (DSP) image processing techniques such as triangulation.

Method and System for Generating a Replay Video
InactiveUS20090290848A1Quality improvementImprove flatnessTelevision system detailsRecording carrier detailsComputer graphics (images)Camera angle
A plurality of cameras are controlled to follow a common moving target in a three dimensional environment such that each camera generates a video feed comprising a plurality of video segments captured sequentially. Each video segment comprises a static image of the target at a respective point in time. A resulting video is generated by selecting a sequence of video segments which may include video segments from different cameras and at the same or different points in time to create various video effects. The recorded video segments are categorized for later recall according to camera identification and point in time to allow for instantaneous recall for producing video replays from a variety of camera angles during a live event. Auxiliary video segments can be computer generated for insertion between video segments captured by the cameras for smoothing the appearance of the resulting video.

Aspects of the present invention include method and apparatuses that may utilize a digital video recording device with a screen control panel, for example, a touch screen control panel, to record digital video data with adjusted light compensation based on a selected object within a scene. For example, a user, using a touch screen control panel, may choose an object within a scene. Based on this selection, the digital video recording device may adjust the backlight compensation settings and camera angle to obtain a better image of the selected object. A user may select an object by touching the image of the object, tracing the selected object, or touching a number of reference points of the object. Then, depending on the user selection, the digital video recording device may take a snapshot, zoom in and take a snapshot, record the scene, or it may lock on the object and readjust and track the object as the object moves, while recording the scene.

Methods for adjusting a picture of an object captured by a camera in a mobile radio communication terminal include defining a first camera angle relative to the object and capturing an image of the object by means of the camera from a second camera angle relative to the object. The second camera angle is offset from the first camera angle. The methods further include storing image data relating to the captured image, and generating an angularly adjusted image of the object in response to the image data and an angular relation between the first camera angle and the second camera angle. Corresponding mobile radio communication terminals are also disclosed. The terminals include an image processing system configured to process an image of an object captured by a camera from a second camera angle by generating an angularly adjusted image of the object in response to image data for the image, and in response to an angular relation between the second camera angle and a first camera angle.

Improvements in a video system are presented that uses one or more camera(s) with a display system. The camera and display system operate together to allow a person to view the back or side of their head as they apply makeup or style their hair. The use of multiple cameras allows the person to view their hair, face or profile from different angles without requiring a single camera to be re-positioned or requiring the person to turn their head to view a particular area. The video system can blend the image from multiple cameras to achieve a view that is not from a single camera. The blending or morphing of the image allows the user the ability to obtain a view from nearly any angle without requiring them to move their head or adjust the camera angle.
