发明名称 Image pickup apparatus
摘要 An image pickup apparatus is capable of accurately performing white balance control by accurately detecting color temperature without depending on a luminance signal level. In the image pickup apparatus, a color evaluation value is obtained by computation from color signals coming from a plurality of pixels of an image sensor having complementary color filters. It is determined whether the color evaluation value is included within a white determining range. The white determining range is made to vary according to the shooting condition and/or the object condition. The white balance is adjusted on the basis of color signals having color evaluation values included within the white determining range.
