Communication terminal, image data communication system, and communication method
An image data communication system includes: a first communication terminal including first circuitry; and a second communication terminal including second circuitry. The first circuitry of the first communication terminal is configured to transmit a plurality of pieces of image data and layer display order information indicating a layer display order in which a plurality of images represented by the plurality of pieces of image data are to be displayed. The second circuitry of the second communication terminal is configured to display the plurality of images represented by the plurality of pieces of image data transmitted from the first communication terminal in the layer display order based on the layer display order information transmitted from the first communication terminal.
1. An image data communication system, comprising:
a first communication terminal including first circuitry; and
a second communication terminal including second circuitry,
the first circuitry of the first communication terminal being configured to transmit a plurality of pieces of image data and layer display order information indicating a layer display order in which a plurality of images represented by the plurality of pieces of image data are to be displayed on different overlapping layer levels on a same overall display region such that when a region where display positions of at least two of the plurality of images overlap with each other, an image from the at least two of the plurality of images with a highest layer level is visible in the region,
the second circuitry of the second communication terminal being configured to display the plurality of images represented by the plurality of pieces of image data transmitted from the first communication terminal in the layer display order based on the layer display order information transmitted from the first communication terminal.
2. The image data communication system of claim 1 ,
wherein the second circuitry of the second communication terminal is further configured to perform image processing of displaying the plurality of images based on the layer display order information.
3. The image data communication system of claim 1 ,
wherein the first circuitry of the first communication terminal is further configured to:
receive a setting of the layer display order; and
transmit the layer display order information after the setting.
4. The image data communication system of claim 1 ,
wherein the plurality of pieces of image data include captured-image data and document image data.
5. The image data communication system of claim 4 , wherein an image represented by the captured-image data is a spherical panoramic image.
6. A communication terminal, comprising circuitry to:
receive a setting of a layer display order in which a plurality of images represented by a plurality of pieces of image data are to be displayed; and
transmit, to another communication terminal, the plurality of pieces of image data and layer display order information, which is information indicating the layer display order, for which the setting is received, in which a plurality of images represented by the plurality of pieces of image data are to be displayed on different overlapping layer levels on a same overall display region such that when a region where display positions of at least two of the plurality of images overlap with each other, an image from the at least two of the plurality of images with a highest layer level is visible in the region,
wherein the another communication terminal is caused to display the transmitted plurality of images in the layer display order based on the transmitted layer display order information.
7. The communication terminal of claim 6 ,
wherein the plurality of pieces of image data include captured-image data and document image data.
8. The communication terminal of claim 7 ,
wherein an image represented by the captured-image data is a spherical panoramic image.
9. An image data communication system, comprising:
the communication terminal of claim 6 ;
the another communication terminal; and
a communication management system configured to control communication of image data between the communication terminal and the another communication terminal.
10. The image data communication system of claim 9 ,
wherein the another communication terminal comprises circuitry to:
receive the plurality of pieces of image data and the layer display order information transmitted from the communication terminal;
overlaying the plurality of images with each other in an order indicated by the layer display order information; and
display an image obtained by overlaying the plurality of images with each other.
11. A method of communicating a plurality of pieces of image data by a communication terminal, the method comprising:
receiving a setting of a layer display order in which a plurality of images represented by the plurality of pieces of image data are to be displayed on different overlapping layer levels on a same overall display region such that when a region where display positions of at least two of the plurality of images overlap with each other, an image from the at least two of the plurality of images with a highest layer level is visible in the region; and
transmitting, to another communication terminal, the plurality of pieces of image data and layer display order information, which is information indicating the layer display order for which the setting is received.
