ABSTRACT:
An image processing apparatus that processes input image data includes an exposure-correction-value acquiring unit that acquires exposure correction values at plural stages with respect to an exposure control value during imaging of the input image data, an illumination-component generating unit that generates illumination components on the basis of the input image data, a gain-amount calculating unit that multiplies each of plural weighting coefficients with a multiplication coefficient corresponding to the exposure correction value corresponding to the weighting coefficient and adds up multiplied values to calculate a gain amount, and a gain applying unit that applies, for each of pixels, the gain amount calculated by the gain-amount calculating unit to the input image data.
