Image display method, image display apparatus, and non-transitory computer-readable storage medium storing display control for displaying images in different forms

An image display apparatus comprising:

• a display section having an input section that accepts a touch input;
• a display control section that performs display control in response to the touch input;
• and
• a storage section that stores a first image, which is rectangular, and a second image, which is rectangular and has a size different from the first image;
• wherein
• the display control section
• acquires the first image and second image stored in the storage section,
• displays, in a first display area, a first display image obtained by reducing the first image and a second display image obtained by reducing the second image,
• displays, when the first display image is selected by the touch input, a first intermediate image based on the first image in a second display area,
• calculates and stores, when the first intermediate image is commanded to be enlarged and moved by the touch input, a display coordinate of the first intermediate image commanded to be enlarged and moved with respect to an enlargement ratio and a prescribed position determined in advance, the display coordinate being stored in the storage section, the enlargement ratio being determined by a size of the first image and a size of a frame enclosing a portion of the first display image in the first display area that is less than an entirety of the first display image in the first display area, and
• displays, when the second display image is selected by the touch input, a second intermediate image based on the second image and enlarged with respect to a position of the second image, the position of the second image corresponding to the prescribed position determined in advance for the first image, in the second display area, according to the enlargement ratio and display coordinate stored in the storage section,
• wherein when the first intermediate image displayed in the second display area includes a corner of the first intermediate image, the display control section uses the corner, corresponding to the corner of the first intermediate image, of the first image as the prescribed position determined in advance of the first intermediate image being commanded to be enlarged and moved by the touch input.

A non-transitory computer-readable storage medium storing a display control program that causes a terminal apparatus to execute display control, the terminal apparatus including a display section having an input section that accepts a touch input, the program comprising:

• causing the terminal apparatus to acquire a first image, which is rectangular, and a second image, which is rectangular and has a size different from the first image;
• causing the terminal apparatus to display, in a first display area, a first display image obtained by reducing the first image and a second display image obtained by reducing the second image;
• causing the terminal apparatus to display, when the first display image is selected by the touch input, a first intermediate image based on the first image in a second display area;
• causing the terminal apparatus to calculate and store, when the first intermediate image is commanded to be enlarged and moved by the touch input, a display coordinate of the first intermediate image commanded to be enlarged and moved with respect to an enlargement ratio and a prescribed position determined in advance, the display coordinate being stored in the storage section, the enlargement ratio being determined by a size of the first image and a size of a frame enclosing a portion of the first display image in the first display area that is less than an entirety of the first display image in the first display area;
• and
• causing the terminal apparatus to display, when the second display image is selected by the touch input, a second intermediate image based on the second image and enlarged with respect to a position of the second image, the position corresponding to the prescribed position, in the second display area, according to the enlargement ratio and display coordinate stored in the storage section,
• wherein when the first intermediate image displayed in the second display area includes a corner of the first intermediate image, the corner, corresponding to the corner of the first intermediate image, of the first image is the prescribed position determined in advance of the first intermediate image being commanded to be enlarged and moved by the touch input.
