PROBLEM TO BE SOLVED: To provide an image processor and an image processing program by which stable white point correction is performed. SOLUTION: A pixel extraction part 16 extracts a pixel used for estimation of a white point from image data acquired by an input acceptance part 12. Next, a color temperature calculation part 18 performs weighting according to a color temperature area to a color temperature value of the extracted pixel, calculates weighted average color temperature to calculate the weighted average color temperature which is a weighted average value of the weighted color temperature. A conversion coefficient generation part 20 generates a conversion coefficient of the white point on the basis of the weighted average color temperature and an image output part 28 converts the input image data using the conversion coefficient and outputs them.
