Abstract:
1. A digital camera configured to carry out strobe photographing using strobe light, comprising: an imaging optical system, which forms an optical image of an object with its background; an image capturing system configured to capture the optical image of the object and the background; a color temperature sensor configured to detect a color temperature of the object and the background illuminated with external light; a white balance adjusting system configured to adjust a white balance of the image captured by the image capturing system; and a color temperature converting filter inserted in an optical path of light which passes through the imaging optical system to form the optical image when the strobe photographing is carried out, the color temperature converting filter converting the color temperature of the external light to a predetermined value, wherein the color temperature converting filter includes a plurality of filters, and one of the plurality of filters is selectively used based on the detected color temperature of the object and the background, and wherein the color temperature converting filter is retracted from the optical path when the strobe photographing is not carried out, and a clear and colorless filter is inserted in the optical path when the color temperature converting filter is retracted.
