Abstract

A display control apparatus performs, when an image is switched to another image while remaining enlarged, display not giving an uncomfortable feeling to a user, and performs control, when a first image enlarged and displayed on a display unit is switched into a second image, to zoom and display, out of a display magnification of the second image based on magnification information used in the first image before the switching and stored, and of a fit magnification for making the second image have a size falling within a display area in the display unit to match the display area, the second image at a magnification that is the fit magnification or more when the display magnification based on the magnification information is smaller, and the second image at the display magnification based on the magnification information when the display magnification based on the magnification information is larger.

Claims15

Dependent claims

A display control apparatus comprising:

a memory;
and
at least one processor, the memory storing a program of instructions executable by the at least one processor, and the at least one processor executes the program of instructions to implement:
changing a display magnification of an image displayed on a display unit based on an operation performed by a user;
receiving a switching instruction to switch an image displayed on the display unit to another image;
and
performing control, when a first image is switched to a second image:
to display the second image at a display magnification according to whether a first display magnification based on a display magnification at which the first image is displayed before a switch to the second image is smaller than a fit magnification,
to display the second image at a second display magnification that is at least the fit magnification if the first display magnification is smaller than the fit magnification, and
to display the second image at the first display magnification if the first display magnification is larger than the fit magnification,
wherein the fit magnification is one of a magnification at which the length of the second image matches the length of the display area and a magnification at which the width of the second image matches the width of the display area.
