Display system, image output apparatus, and non-transitory computer-readable storage medium storing program

An image output apparatus comprising:

• a display apparatus, a communication apparatus that transmits an image to the display apparatus;
• and at least one processor,
• wherein the processor performs:
• transmitting an image having a first aspect ratio via the communication apparatus,
• receiving resolution information from the display apparatus via the communication apparatus, the resolution information containing information indicating a first resolution that is a resolution in a first direction and a second resolution that is a resolution in a second direction perpendicular to the first direction, and
• outputting a first image to the display apparatus based on the resolution information when receiving the resolution information, the first image having a third resolution lower than the first resolution, and the second resolution and having an aspect ratio equal to the first aspect ratio,
• the display apparatus includes an optical apparatus that displays an image in a display region,
• a placement region where the second image is placed is set in the display region,
• the first and second resolutions are a resolution of the placement region or a resolution corresponding to an aspect ratio of the placement region, and
• the display apparatus performs:
• accepting the operation of changing the resolution of the placement region,
• changing the resolution of the second image to the changed resolution of the placement region in accordance with the operation,
• displaying the second image the resolution of which is the changed resolution of the placement region, and
• transmitting the resolution information containing the first and second resolutions corresponding to the changed resolution of the placement region to the processor when accepting the operation of finalizing the resolution of the placement region.

A non-transitory computer-readable storage medium storing a program executed by a computer including a display apparatus and a communication apparatus that transmits an image,

• the program causing the computer to perform
• transmitting an image having a first aspect ratio via the communication apparatus,
• receiving resolution information from the display apparatus via the communication apparatus, the resolution information containing information indicating a first resolution that is a resolution in a first direction and a second resolution that is a resolution in a second direction perpendicular to the first direction, and
• outputting a first image to the display apparatus based on the resolution information when receiving the resolution information, the first image having a third resolution lower than the first resolution, and the second resolution and having an aspect ratio equal to the first aspect ratio, wherein
• the display apparatus includes an optical apparatus that displays an image in a display region,
• a placement region where the second image is placed is set in the display region, and
• the first and second resolutions are a resolution of the placement region or a resolution corresponding to an aspect ratio of the placement region,
• the program causing the display apparatus to perform:
• accepting the operation of changing the resolution of the placement region,
• changing the resolution of the second image to the changed resolution of the placement region in accordance with the operation,
• displaying the second image the resolution of which is the changed resolution of the placement region, and
• transmitting the resolution information containing the first and second resolutions corresponding to the changed resolution of the placement region to the computer when accepting the operation of finalizing the resolution of the placement region.
