Abstract: An IR emitter internally mounted behind the screen of a projection television apparatus. The IR emitter is mounted so as not to interfere with the image display light path. The IR emitter is mounted so that IR rays are reflected off the mirror and exit through the screen of the projection television. The IR emitter includes one or more IR type LEDs.

Abstract: Systems and methods that facilitate the use and operation of a television with an integrated sound projection system. The sound projector preferably comprises an array of speakers configurable to project beams that reflect off the walls and ceiling to create surround sound. In one embodiment, sound can be projected and/or the television can be oriented automatically as a function of the location of the television remote control unit.

Abstract: Improved systems and methods that facilitate orienting the direction of an antenna for viewing digital television signals from available broadcast stations. An embodiment includes an antenna directional guide displayable on a screen of a television enabling the viewer to select an antenna direction to view television signals receivable by the antenna from broadcast stations located along selected reception direction of the antenna.

Abstract: Improved systems and methods that facilitate automatic detection of 3D content in a video program signals and, based on the detection of 3D content, automatically switches as the program signal processing and display mode of the television to 3D format. A 3D detection module parses frames of an input video program signal into first and second images and determines the level of correlation between the images by motion vector and histogram information from the images.

Abstract: Systems and methods for effectively and naturally enhancing the relative contrast between an image object and the surrounding background image in television pictures. In one embodiment, a television system preferably comprises a central processing unit (CPU) coupled to an audio-video output unit. The CPU preferably comprises non-volatile memory coupled to a logic unit which is adapted to receive and process a program signal SP and output an enhanced program signal SEP to the audio-video output unit. The logic unit preferably includes a differential waveform generator in one embodiment and a low pass filter in another embodiment. In operation in one embodiment, a waveform comprising a second differential of an original waveform and an inverted copy of the second differential of the original waveform is low pass filtered, and, depending on the shape of the original waveform, inverted prior to adding it to the original waveform to generate an enhanced waveform with improved relative contrast.

Abstract: A video camera wherein the number of times that an output signal from a swing sensor reaches or exceeds a threshold value is counted, and based on the resulting counted value, the video camera is judged as being in a photographing state or not, the recording operation being stopped if the video camera is judged to be not in a photographing state. When the counted value has reached a predetermined value, the operator of the video camera is notified of a faulty photographing condition. Furthermore, it is judged, based on the detection result of the swing sensor, whether the video camera is in a misrecording operation; if the video camera is judged to be in a misrecording operation, the recording operation is stopped, and then, the recording tape is rewound to the start position of the misrecording.
