  • Patent number: 7936095
    Abstract: When a certain period of time has elapsed since a direction retrieval unit received a control signal from an appliance controller, the direction retrieval unit instructs the microwave transmitter to transmit microwaves, and then instructs the microwave transmitter to perform scanning of the microwaves. When a notification signal receiver receives a notification signal from a remote controller, the direction retrieval unit instructs the microwave transmitter to stop the scanning of the microwaves. After this, the direction retrieval unit instructs a power controller to raise a power level of the microwaves.

  • Patent number: 7209182
    Abstract: A false contour correcting apparatus is capable of removing a false contour in an image based on a digital image signal while avoiding such a side effect caused by false contour correction where noises negatively effecting the display occur on a screen. Therefore, in the false contour correcting apparatus according, a double bit change detection circuit detects as a double bit change a signal value change which is twice a minimum quantization unit in a digital image signal, and outputs a double bit change detection signal representing the position of the double bit change. A signal correction circuit corrects the double bit change in the digital image signal into two one-bit changes on the basis of the double bit change detection signal. Consequently, a false contour corresponding to a portion where the double bit change exists is removed.

  • Patent number: 6373533
    Abstract: The tone of video signals is corrected without degrading the tone of certain image features, such as a human face. A gain controller operates and outputs an adjustment value using a histogram output produced by a histogram generator. An average value of picture levels on a screen is detected by an average picture level detector. A histogram correction circuit calculates a look-up table, and a video signal correction circuit corrects the tone of the video signals using the look-up table.

  • Patent number: 6295095
    Abstract: In a video signal character converting device, a sampling window signal generator generates a signal for sampling an input video signal “a”. A video scene amplitude discrimination circuit samples the video signal in response to the sampling signal, detects a change in image level either field by field or frame by frame based on an integrated value for every duration of vertical scanning, and outputs a resetting pulse when the change in picture level exceeds a predetermined level. A video scene periodicity discrimination circuit measures a time interval between two successive resetting pulses, and outputs a control signal if the time interval is shorter than a predetermined period. A video scene conversion circuit converts a video scene in response to the control signal.

  • Patent number: 6252983
    Abstract: A histogram generator creates a histogram to detect the characteristics of video signals. The histogram generator allows for a reduction in problems of instability caused by noise that may exist in other histogram generators. A width is allocated to thresholds used in creating the histogram, and signal values are counted after weighting those falling near a threshold.
