摘要： The present invention provides a boost switching power supply with low switching loss. The boost switching power supply of the present invention includes a coil portion 3a and a first diode 4 that are serially connected between one terminal of a DC power source 2 and one terminal of a first capacitor 5 for smoothing, a first switching element 8 connected between a node A where the coil portion 3a and the first diode 4 are connected and the other terminal of the DC power source 2, a second magnetic element 7 and a second switching element 9 that are serially connected between the node A and the other terminal of the DC power source 2, and a second diode 10 and a second capacitor 11 that are serially connected between a node where the second magnetic element 7 and the second switching element 9 are connected and the node A. According to the present invention, the switching loss of the second switching element 9 is reduced substantially because when the second switching element 9 turns ON, the increase of the current flowing in the second switching element 9 is restricted by the second magnetic element 7 and when the second switching element 9 turns OFF, the increase in voltage across the electrodes of the second switching element is restricted by the charging the second capacitor 11.

摘要： A camera includes a plurality of photosensors disposed on an imaging surface. The photosensors separately output respective photodetection signals, and are grouped into a plurality of photosensitive units each including at least two of the photosensors. The photosensors of each of the photosensitive units have respective detection wavelength ranges which do not overlap one another. The photodetection signals outputted from selected ones of the photosensors of each of the photosensitive units are used in performing spectrum analysis. R (red), G (green), and B (blue) signals are synthesized from the photodetection signals outputted from the photosensors of each of the photosensitive units and are used in displaying an ordinary color image.
