    • An image processor is provided, which has the capability of detecting an object such as a human face from an image taken against the sun with high accuracy. An image signal provided from an image pickup unit is adjusted at an analog gain by an image adjuster. An out of the image adjuster is converted into a digital, and store in a memory. A feature of the object is extracted from this digital image data to detect an object area in the image. When the object area is not detected, an analog-gain controller sends that the image signal provided from the image pickup unit is adjusted at a different analog gain. Thus, the treatment of detecting the object area is repeated at different analog gains.
    • 提供一种图像处理器,其具有以高精度从对太阳拍摄的图像中检测诸如人脸的物体的能力。 由图像拾取单元提供的图像信号由图像调节器调节为模拟增益。 图像调整器的输出被转换为数字图像数据,并存储在存储器中。 从该数字图像数据中提取对象的特征以检测图像中的对象区域。 当未检测到对象区域时,模拟增益控制器以反馈方式向图像调整器发送模拟增益控制信号,使得从图像拾取单元提供的图像信号被调整为不同的模拟增益。 因此,以不同的模拟增益重复检测对象区域的处理。

    • In a wiring device which detects a leakage current in an electrical path connecting a commercial power supply and a load to interrupt the electrical path, the electrical leakage can reliably be interrupted even when the leakage current has a distorted waveform. A wiring device (1) includes a leakage control unit (4) for detecting a leakage current flowing through an electrical path connecting a commercial power supply and a load (30) to perform a leakage determination and a switching unit (2) for interrupting the electrical path in accordance with the leakage determination of the leakage control unit (4). The leakage control unit (4) has a filter (42) for filtering the detected leakage current and having a frequency characteristic which the human body has with respect to an electrical shock, a square operation unit (43) for calculating the square operation value of a signal which relates to the leakage current passing through the filter (42), and a threshold determination unit (46) for performing the leakage determination in accordance with the square operation value obtained by the square operation unit (43). Consequently, the leakage determination is performed in accordance with the square operation value, so that the leakage can be detected with high accuracy even when the leakage current has a distorted waveform, and the electrical leakage can be reliably interrupted.

    • An apparatus and method thereof for igniting and operating a high intensity discharge (HID) lamp during an in service life, and powering down the lamp when an end-of-life (EOL) lamp condition is detected. The apparatus and method defines a series of thresholds of lamp voltage asymmetry, or rectification thresholds, and monitors the lamp rectification from ignition through normal operation. The detection scheme is masked off for a predetermined period of time when the lamp is initially started. Thereafter, the rectification threshold of the lamp voltage asymmetry is gradually reduced over time, until a defined minimum rectification threshold level is reached and maintained. The method continuously monitors the lamp voltage and records whenever the lamp voltage asymmetry is higher than the rectification threshold level at any lamp voltage cycle. An EOL lamp condition is determined to exist when a certain number of high asymmetrical cycles occurs in selected total number of lamp voltage cycles during a rolling measurement window.
