Display control apparatus and method of controlling display control apparatus

A method of controlling a display control apparatus, the method comprising:

• reading audio data and allocation data for playing the audio data in synchronism with images, a displaying timing of images in synchronism with the audio data and categories of the images being associated with each other in the allocation data;
• selecting, by a user operation, images to be allocated, for each of the categories included in the allocation data;
• receiving an instruction to change a displaying timing of an image from a first displaying timing to a second displaying timing;
• determining a displaying order of the images, wherein the determining the displaying order comprises rearranging an order for displaying the images based on the instruction in a case where the second displaying timing is associated with a category to which the image is allocated, and wherein the determining the displaying order comprises rejecting the instruction to change the displaying timing of the image in a case where the second displaying timing is not associated with the category to which the image is allocated;
• and
• performing control so that the audio data are played and images allocated to the categories are displayed at a displaying timing associated with the categories in the allocation data, to thereby display the images sequentially in the displaying order in synchronism with the audio data.

A non-transitory computer-readable storage medium storing instructions that, when executed by a computer of a display control apparatus, cause the computer to perform operations comprising:

• reading audio data and allocation data for playing the audio data in synchronism with images, a displaying timing of images in synchronism with the audio data and categories of the images being associated with each other in the allocation data;
• selecting, by a user operation, images to be allocated, for each of the categories included in the allocation data;
• receiving an instruction to change a displaying timing of an image from a first displaying timing to a second displaying timing;
• determining a displaying order of the images, wherein the determining the displaying order comprises rearranging an order for displaying the images based on the instruction in a case where the second displaying timing is associated with a category to which the image is allocated, and wherein the determining the displaying order comprises rejecting the instruction to change the displaying timing of the image in a case where the second displaying timing is not associated with the category to which the image is allocated;
• and
• performing control so that the audio data are played and images allocated to the categories are displayed at a displaying timing associated with the categories in the allocation data, to thereby display the images sequentially in the displaying order in synchronism with the audio data.
