Electronic apparatus operating method and electronic apparatus

1. A method for operating an electronic apparatus, the method comprising:

displaying, by a display apparatus, a first image based on first image data transmitted from a first terminal apparatus to the electronic apparatus in a first area of a display surface and a second image based on second image data transmitted from a second terminal apparatus to the electronic apparatus in a second area of the display surface that is different from the first area;

changing, by the first terminal apparatus, an amount of the first image data transmitted by the first terminal apparatus per unit time period to the electronic apparatus in accordance with a change instruction to change a size of the first area; and

changing, by the second terminal apparatus, an amount of the second image data transmitted by the second terminal apparatus per unit time period to the electronic apparatus in accordance with a change instruction to change a size of the second area,

wherein operation of selecting the first image and the second image is determined as the change instruction,

wherein when the change instruction is a reduction instruction to reduce the first area, the first terminal apparatus decreases the amount of the first image data, and

wherein when the change instruction is an enlargement instruction to enlarge the second area, the second terminal apparatus increases the amount of the second image data.

2. The operation method according to claim 1 ,

wherein the changing includes changing the amount of the first image data by changing a data format of the first image data in accordance with the change instruction.

3. The operation method according to claim 1 ,

wherein the changing includes changing the amount of the first image data by changing resolution of the first image data in accordance with the change instruction.

4. The operation method according to claim 1 ,

wherein the changing includes changing the amount of the first image data by changing a compression method for compressing the first image data in accordance with the change instruction.

5. The operation method according to claim 1 ,

wherein the changing includes changing the amount of the first image data by changing a compression ratio at which the first image data is compressed in accordance with the change instruction.

6. The operation method according to claim 1 ,

wherein the changing includes changing the amount of the first image by changing the number of colors representing the first image data in accordance with the change instruction.

7. The operation method according to claim 1 ,

wherein the changing includes changing the amount of the first image data by changing a frame rate at which the first image data is transmitted in accordance with the change instruction.

8. An electronic apparatus comprising:

one or more processors configured to

cause a display apparatus to display a first image based on first image data transmitted from a first terminal apparatus to the electronic apparatus in a first area of a display surface and a second image based on second image data transmitted from a second terminal apparatus to the electronic apparatus in a second area of the display surface that is different from the first area;

cause the first terminal apparatus to change an amount of the first image data transmitted by the first terminal apparatus per unit time period to the electronic apparatus in accordance with a change instruction to change a size of the first area; and

cause the second terminal apparatus to change an amount of the second image data transmitted by the second terminal apparatus per unit time period to the electronic apparatus in accordance with a change instruction to change a size of the second area,

wherein when the change instruction is a reduction instruction to reduce the first area, the one or more processors are configured to cause the first terminal apparatus to decrease the amount of the first image data, and

wherein when the change instruction is an enlargement instruction to enlarge the second area, the one or more processors are configured to cause the second terminal apparatus to increase the amount of the second image data.
