ABSTRACT:
In an image capturing apparatus, a hue shift is prevented. A digital camera has a gray level correction function. Image data obtained with a CCD10is divided into a plurality of blocks and further has brightness data and color difference data converted in a brightness/color difference conversion section20. When it is determined, based on the color difference data, that image data includes blue sky image or that chroma of the image data is high, an image processing exposure compensation adjustment/exposure correction amount calculation section30sets an underexposure value, which is employed when capturing images with an exposure value being lower than a correct exposure value, to be smaller than a default value to prevent a hue shift caused by gray level correction performed by a gray level correction section32.
