Abstract:
A digital camera including an imaging unit, a flash device, a face region extraction unit for detecting a face region from image data generated by the imaging unit, and a flash control unit for controlling emission amount of the flash using the region information outputted from the face region extraction unit. The flash control unit includes a first calculation means for performing a calculation on the image data generated by the imaging unit without using the region information, a second calculation means for performing a calculation on the image data generated by the imaging unit using the region information, and an emission amount determination means for determining an adequate emission amount Ch of the flash by performing an adjustment using the provisional adequate value Cn supplied from the first calculation means and provisional adequate value Cf supplied from the second calculation means as reference values.
