An imaging apparatus includes an image pickup element to acquire a short-exposure-image data and a long-exposure-image data; a white balance evaluation value acquiring device to acquire white balance evaluation value for each of short-exposure-image data and long-exposure-image data; a white extraction range setting device to set a white extraction range for each of short-exposure-image data and long-exposure-image data; a white extraction device to extract white extraction result on the basis of the white balance evaluation value and the white extraction range for each of short-exposure-image data and long-exposure-image data; a correction factor calculating device to calculate corrected white extraction results from the white extraction result on the basis of the white extraction range and calculate correction factor for each of short-exposure-image data and long-exposure-image data; a white balance correcting device to correct the short-exposure-image data and the long-exposure-image data to form white balance corrected short-exposure-image data and white balance corrected long-exposure-image data by using the correction factors; and a synthesizing device configured to synthesize the white balance corrected short-exposure-image data and the white balance corrected long-exposure-image data.
