<p>A chroma adjusting method for use in an automatic white balance adjusting method to control the gains of red and blue signals in accordance with signals obtained by photographing an object. In the chroma adjusting method, the chroma information that corresponds to the ratio of high-chroma colors in the entire screen can be found in accordance with signals obtained by photographing an object. The gain of a chroma signal is controlled such that the gain of the chroma signal can be increased as the chroma information is decreased. When there are present many low-chroma colors, the chroma level of the chroma signal can be raised.</p> |
