Abstract

An image processing apparatus includes a generation unit and a display control unit. The generation unit generates a subtraction image using a first region and a second region, the first region being a portion of a first fundus image acquired by performing autofluorescence imaging on a fundus of an eye to be inspected, the second region being a portion of a second fundus image acquired by performing autofluorescence imaging on the fundus of the eye to be inspected at a time different from that of the first fundus image and being at a position corresponding to the first region. The display control unit causes a display unit to display an image generated by superimposing information regarding the subtraction image at a position corresponding to the first and second regions on a fundus image acquired by performing autofluorescence imaging on the fundus.
