Abstract:
1. A digital camera in which at least two types of white balance gains are computed with regard to a single image data item captured by the digital camera, the digital camera comprising: first gain computation means for computing from the captured image data, as a first gain, a white balance gain in accordance with a first light source condition designated by the user, wherein fluorescent light is designated by a user as the first light source condition and the first gain computation means includes: fluorescent type determination means for determining a type of fluorescent light which was used as a light source when an image was actually captured based on the captured image data; and computation means for computing, as the first gain, a manual white balance gain using the type of fluorescent light determined by the fluorescent type determination means as a type of light source designated by the user; second gain computation means for computing from the captured image data, as a second gain, a white balance gain in accordance with a second light source condition; and an intermediate calculation means for calculating one or more parameters for each pixel, and outputting an intermediate calculation result, wherein both of the first and second gain computation means use the intermediate calculation result outputted by the intermediate calculation means for computing the first and second gain.
