摘要： An image generating apparatus that generates an output image using a difference between an uncorrected pixel in an image and a smoothed pixel obtained by smoothing the uncorrected pixel. The image generating apparatus includes a storage unit, a tone-converted uncorrected pixel generating unit, a tone-converted smoothed pixel generating unit, and an output image generating unit. The storage unit stores an uncorrected pixel tone table for converting the uncorrected pixel and a smoothed pixel tone table for converting the smoothed pixel. The tone-converted uncorrected pixel generating unit converts the uncorrected pixel to a tone-converted uncorrected pixel based on the uncorrected pixel tone table. The tone-converted smoothed pixel generating unit converts the smoothed pixel to a tone-converted smoothed pixel based on the smoothed pixel tone table. The output image generating unit generates the output image based on a difference between the tone-converted uncorrected pixel and the tone-converted smoothed pixel.
