A still-video camera has a white balance adjustment device. The white balance adjustment device includes a filter film which has a translucent opal filter portion and a transparent filter portion. The filter film is moved by a motor. During a white balance adjustment, the translucent opal filter portion is positioned in front of a first CCD, and in an image recording operation, the transparent filter portion is positioned in front of the first CCD. When the white balance adjustment is to be carried out, an output signal from a second CCD is transmitted to an AF control circuit, and thus an AF adjustment is also performed. The AF adjustment is carried out in such a manner that a spatial frequency of the output signal of the second CCD has a highest value.
