摘要： A load drive apparatus includes a switching device, a gate drive circuit, a clamp circuit, a temperature detection circuit, and an arithmetic device. The switching device controls an on-off state of current supply to a load. The gate drive circuit turns on the switching device by controlling a gate voltage of the switching device so that the switching device operates in a full-on state. The clamp circuit clamps the gate voltage of the switching device to a clamp voltage lower than the gate voltage in the full-on state and higher than a mirror voltage. The temperature detection circuit detects a temperature of the switching device. The arithmetic device calculates a voltage corresponding to a variation in a mirror voltage based on the detected temperature and controls the clamp voltage in the clamp circuit so as to be the calculated voltage.

摘要： Prepare digital data of a value of each pixel within an object image region including a region of a human face. Then, successively, in the object image region, extract position of a Between-the-Eyes candidate point through a filtering process with a Between-the-Eyes detecting filter in which six rectangles Si (1≦i≦6) are connected. Further, extracting a portion of the object image in a prescribed size which has the extracted position of the Between-the-Eyes candidate point at a center, and select a true candidate point from said Between-the-Eyes candidate points in accordance with a pattern discriminating process.

摘要： A load driving apparatus for driving a load with a constant current includes a shunt resistor and a driver circuit. A shunt current corresponding to the constant current flows though the shunt resistor. The driver circuit is connected to a first end of the shunt resistor to supply the constant current corresponding to the shunt current to the load. The driver circuit includes a reference voltage source for generating a predetermined reference voltage. The driver circuit adjusts the magnitude of the constant current by performing a feedback-control of the magnitude of the shunt current in such a manner that a first voltage corresponding to the reference voltage and a second voltage corresponding to a voltage at the first end of the shunt resistor become equal to each other.

摘要： A load driver includes a switching element connected to a load, a constant current generator that generates a constant current, and a driver circuit that turns on the switching element for an on-period, which depends on a value of the constant current and is shortened with an increase in the value of the constant current. The constant current generator supplies a first constant current having a first current value to the driver circuit during the on-period, and supplies a second constant current having a second current value smaller than the first current value after the on-period has elapsed and the switching element reaches an on state.
