In an image reproducing apparatus capable of performing group reproduction, a related image determination unit determines whether an image read by an image reading unit is an image included in a plurality of related images, which are related to each other, and if it is determined by the related image determination unit that the image read by the image reading unit is an image included in the plurality of related images, a representative image detection unit detects a representative image from a plurality of images constituting the plurality of related images including the read image, and a display processing unit causes a display unit to display the representative image detected by the representative image detection unit.
