Methods and systems for discriminating between ventricular waveforms when ventricular rate exceeds atrial rate
A ventricular rate based on first candidate waveforms and second candidate waveforms within sensed ventricular waveforms is compared to an atrial rate. If the ventricular rate exceeds the atrial rate, the first candidate waveforms and second candidate waveforms are compared to a ventricular polarization complex template to obtain a first morphology indicator and a second morphology indicator. If a morphology match inconsistency is present, the amount by which the ventricular rate exceeds the atrial rate is compared to a threshold. If the threshold is exceeded, high-ventricular-rate therapy to the heart is inhibited. The ventricular polarization complex template may be a QRS-complex template, in which case a match inconsistency is present if each of the first candidate waveforms and the second candidate waveforms do not match the QRS-complex template. Alternatively, the ventricular polarization complex template may be a T-wave template, in which case a match inconsistency is present if either of the first candidate waveforms and the second candidate waveforms matches the T-wave template. |

Poor video editing detection system
A system for detecting poor video editing detects a television (TV) image signal. When a TV image originates from a film signal rather than a video signal, a de-interlacing device performs a de-interlacing at a film signal mode to thereby increase a vertical resolution of a TV image signal. A sawtooth detector can detect a poor video editing, which causes a sawtooth occurrence to TV image signals, on an unbroadcasted TV image signal. Accordingly, the poor video editing is found in advance. Also, the invention uses a scene change in combination with the sawtooth detector to thereby avoid a poor edited image and obtain a preferred image quality. |

Scanning line interpolating device and scanning line interpolation method
An interpolation processing section determines a pixel value of an interpolation-target pixel by a diagonal interpolation process. An interpolation value limiting section compensates the pixel value determined by the interpolation processing section such that it becomes a value between pixel values of two adjacent pixels above and below the interpolation-target pixel. An intersection area detecting section judges whether or not the interpolation-target pixel is located in, when the horizontal axis represents a horizontal position and the vertical axis represents a pixel value, an area in proximity of a horizontal position where a curve line, representing pixel values of pixels on the scanning line above the interpolation-target pixel, and a curve line, representing pixel values of pixels on the scanning line below the interpolation-target pixel, intersects. Depending on a judgment result by the intersection area detecting section, a selecting section selectively outputs a pixel value determined by the interpolation processing section, or a pixel value compensated by the interpolation value limiting section, as an interpolated video signal. By this, the advantageous effect of the diagonal interpolation process is fully exerted while suppressing image quality degradation due to a false operation of the diagonal interpolation process. |

Auto focus system having AF frame auto-tracking function
When the user sets an AF frame such that an object tracked as an AF target is in the AF frame, an auto-tracking process starts to detect a face image from the image captured by a television camera. Then, it is determined whether the face image is detected from the peripheral range of the AF frame. If it is determined that the face image is detected from the peripheral range of the AF frame, the position of the AF frame is changed on the basis of the position of the face image. On the other hand, if it is determined that the face image is not detected from the peripheral range of the AF frame, a pattern matching process is performed. The position of the AF frame is changed to the position of the object, which is a tracking target, detected by the pattern matching process. |

If a larger number of pieces of attribute information are prepared so as to attain advanced input image processing and output image processing, the number of bits of each attribute signal increases, thus increasing the data size of the signal. For this reason, the storage capacity consumed by a storage unit that holds attribute signals may increase, and generation, write, and read speeds of attribute signals may decrease. To solve such problems, attribute regions included in a drawing command are discriminated, the number of types of attribute regions is counted to determine the bitwidth of attribute information based on the number of types of attribute regions, and the attribute information is generated by creating an attribute information table. |

Systems and methods for semi-independent loop processing
Various embodiments of the present invention provide systems and methods for data processing. For example, a data processing circuit is discussed that includes an analog to digital converter circuit, a digital filter circuit, a data detector circuit, a mimic filter circuit, and a sample clock generation circuit. The analog to digital converter circuit is operable to receive a data input and to provide corresponding digital samples. The digital filter circuit is operable to receive the digital samples and to provide a filtered output. The data detector circuit is operable to perform a data detection process on the filtered output to yield a detected output. The mimic filter circuit is operable to receive the digital samples and to provide a mimicked output. The sample clock generation circuit is operable to provide a sample clock based at least in part on the detected output and the mimicked output. |

Continuously-arranged sensor system, network unit, and sensor unit
A continuously-arranged sensor system is provided that can eliminate a shift in timing between a determination signal of each sensor unit and sensor information relating to the determination signal. The continuously-arranged sensor system includes a network unit and a plurality of sensor units, which are connected by a serial transmission line and a parallel transmission line. In accordance with a command sent from the network unit, each sensor unit transmits the determination signal and the sensor information, provided at the same time as the determination signal, to the network unit via the serial transmission line. Therefore, the network unit can obtain the determination signal and the sensor information exhibited at the same time. |
