Illumination apparatus, imaging apparatus and irradiation method

An imaging apparatus having an image pickup device for imaging a photo-object and also having a function for imaging a moving picture made up of a plurality of frames, said imaging apparatus comprising:

• light emitting diodes which are a light source of an auxiliary light to be irradiated onto a photo-object;
• and
• a driver which duty-drives said light emitting diodes during an imaging period of a frame period.

An imaging apparatus having an image pickup device for imaging a photo-object and also having a function for imaging a moving picture made up of a plurality of frames, said imaging apparatus comprising:

• a plurality of light emitting diodes which are a light source of an auxiliary light to be irradiated onto a photo-object;
• and
• driver which drives said plurality of light emitting diodes by sequentially switching said light emitting diodes to be driven during a same imaging period of a frame period.

An imaging apparatus having an image pickup device for imaging a photo-object and also having a function for taking a moving picture made up of a plurality of frames, said imaging apparatus comprising:

• a plurality of light emitting diodes which are a light source of an auxiliary light to be irradiated onto a photo-object;
• and
• a driver which sequentially drives said plurality of light emitting diodes by synchronizing periods for driving said light emitting diodes during a same imaging period of a frame period.
