摘要： In one aspect there is provided an embodiment of an image capture device comprising a camera, an image processor, a storage device and an interface. The camera is configured to capture images in visible spectrum light of a human finger as part of a human hand in a field of view (FOV) of the camera. The image processor is configured to process a first one of the images to detect a presence of the finger. The image capture device is configured to detect the position of the presence of the finger tip, track movement of the finger tip within the FOV by processing at least a second one of the images and generate a command based on the tracked movement of the finger within the FOV. The method does not require any pre-detection training sequence with said finger prior to finger detection, and does not require the finger to be in specific relative angle or finger orientation in said FOV. If the human hand is holding a “finger” like object, such as a pen or stick, such object will be recognized as finger and the tip of the object will be recognized as finger tip and position is also detected. The interface is configured to transmit the detection of the presence of the finger, the assigned position of the finger tip and the command to an external apparatus.

摘要： In one aspect there is provided an embodiment of an image capture device comprising a camera, an image processor, a storage device and an interface. The camera is configured to capture images in ambient light of a human hand in a field of view (FOV) of the camera. The image processor is configured to process a first one of the images to detect a presence of the hand. The image capture device is configured to assign a position of the presence of the hand, track movement of the hand within the FOV by processing at least a second one of the images and generate a command based on the tracked movement of the hand within the FOV. The interface is configured to transmit the detection of the presence of the hand, the assigned position of the hand and the command to an external apparatus.

摘要： One aspect provides an image capture device which, in one embodiment, includes a camera, image processor, and interface. The image processor is configured to determine a location of at least one eye of a presenter in a captured image captured by the camera. The image processor is also configured to cause a projection control processor external to the image capture device to modify a corresponding location of a projectable image.
