A display control apparatus controls to execute variable magnification processing of a partial image of an image indicated by a display range, and to display the partial image in a display area. The display control apparatus comprises a calculation unit which obtains a vertex/vertexes of the display range farthest from a center of the image, and sets the vertex or a center point of the vertexes as a reference point, a changing unit which changes a size of the display range while keeping the position of the reference point, a moving unit which moves the display range in the image, and a display control unit which controls to execute the variable magnification processing of the partial image, and to display the partial image in the display area. The calculation unit re-calculates the reference point in response to movement of the display range in the image by the moving unit. |
