Image processing apparatus, computer-readable medium storing an image processing program, and image processing method
An image processing apparatus that can be connected to a display device and removes blurring from a first-order image is provided. The image processing apparatus includes a generation unit, a display control unit, and a selection reception unit. The generation unit generates multiple I-th order intermediate images by performing blur correction in multiple blur directions on an I-th order image. The display control unit causes the multiple I-th order intermediate images to be displayed on the display device. The selection reception unit allows the user to select an (I+1)-th order image from among the displayed multiple I-th order intermediate images as a corrected image whose blurring has been reduced more than in the I-th order image. The generation unit, the display control unit, and the selection reception unit execute the above processing in order with respect to I=1, 2, . . . , K (K being a natural number).
