초록 ▼

A power supply circuit for a digital camera, including a DC power supply device for supplying direct current power; an image inputting device driven by the DC power supply device; a light emitting diode device driven by the DC power supply device and which auxiliary illuminates a subject to be imaged by the image inputting device; and a backup device connected to an output side of the DC power supply device and adapted for preliminarily charging the direct current power.

대표청구항 ▼

What is claimed is: 1. A power supply circuit for a digital camera, comprising: a power supply device which supplies power; an image inputting device driven by the power supplied from said power supply device; a strobe emitter driven by the power supplied from said power supply device and which auxiliarly illuminates a subject to be imaged by said image inputting device; a strobe emitter drive circuit inserted between the power supply device and the strobe emitter, and which supplies the power supplied from the power supply device to the strobe emitter to drive the strobe emitter; a light emitting diode device connected with the strobe emitter drive circuit and driven by the power supplied from the power supply device through the strobe emitter drive circuit, and which auxiliarly illuminates the subject to be imaged by the image inputting device; and a controller which selects at least one of said light emitting diode device and said strobe emitter to auxiliarly illuminate the subject, and which drives said strobe emitter drive circuit to supply the power supplied from the power supply device to the light emitting diode device to drive the light emitting diode device when said light emitting diode device is selected, the strobe emitter drive circuit including a blocking oscillation controlling circuit connected to an output side of the power supply device and controlled by the controller, and a boosting transformer inserted between the blocking oscillation controlling circuit and the strobe emitter and connected with the light emitting diode device, and driven by the block oscillation controlling circuit to output the power supplied from the power supply device to the strobe emitter and the light emitting diode device. 2. The power supply circuit for the digital camera according to claim 1, wherein the controller selects the light emitting diode device to auxiliarly illuminate the subject when close-photographing of the subject is performed, and selects the strobe emitter to auxiliarly illuminate the subject when distant-view photographing of the subject is performed. 3. The power supply circuit for the digital camera according to claim 1, further comprising a backup block including a backup element connected between an output side of the power supply device and which preliminarily charges the power supplied from the power supply device, and a discharging direction-rectifying device inserted between the backup element and the light emitting diode device and which turns on to supply the power charged in the backup element to the light emitting diode device when an output voltage of the power supply device becomes lower than a predetermined value. 4. The power supply circuit for the digital camera according to claim 1, further comprising a backup block including a backup element connected between an output side of the power supply device and the light emitting diode device, and which preliminarily charges the power supplied from the power supply device and supplies the charged power to the light emitting diode device.
