Abstract

A display control apparatus that enables to reliably and quickly search for a desired image. When a wheel is operated by a user by an amount less than a predetermined operation amount, image feeding is made in a first display mode where a plurality of images are displayed on an image display unit. When the wheel is operated by the user by an amount equal to or greater than the predetermined operation amount, image feeding is made in a second display mode where a larger number of images than in the first display mode are displayed on the image display unit in a smaller size than in the first display mode.
