  • Patent number: 7965333
    Abstract: For noise correction in connection with a flat-panel x-ray detector (2), noise signals of a dark area (6) are checked for deviations exceeding a specified threshold (g) which, if any are present, will be taken into consideration separately for calculating the correction factor derived from the noise signal. Image artifacts due, for example, to high-contrast objects such as, for instance, cardiac pacemakers or metallic implants, in the x-ray image will be avoided through this measure.

  • Patent number: 7965324
    Abstract: A video-signal-processing device has luminance conversion section that performs level compression on three input primary-color signals of a color video signal at a same luminance adjustment compression ratio with a hue and a saturation of the color video signal being kept constant, thereby generating three compressed primary-color signals. The device also has saturation conversion section that performs level conversion on the three compressed primary-color signals by using a saturation compression ratio if a maximum level of at least one of the three compressed primary-color signals exceeds a first level. The saturation conversion section sets the saturation compression ratio by using a minimum level one of the three compressed primary-color signals.

  • Patent number: 7956917
    Abstract: The present invention relates to a sensor apparatus having a structure capable of obtaining digital values of signal components with a high accuracy using an A/D conversing circuit with the outputted digital value thereof having a small number of expressive bits. In the sensor apparatus, a voltage value corresponding to the amount of incident light to a photodiode is held by a holding circuit through an integrating circuit and a CDS circuit. Meanwhile, a voltage value corresponding to the amount of incident light to an adjacent photodiode is held by another holding circuit through an integrating circuit and a CDS circuit. The voltage values held by the respective different holding circuits are inputted to a subtracting circuit through different paths. The subtracting circuit outputs a voltage value corresponding to the difference between the two inputted voltage values. In an A/D converting section, the difference voltage outputted from the subtracting circuit is converted into a digital value.
