Abstract
In an image communication system including a server which stores image data encoded in accordance with a hierarchy coding, and a client configured to download the image data from the server and display the image data, the server determines on the basis of a request received from the client whether a specific command is requested, when the specific command is requested, generates return data by adding additional data representing the encoding condition of the image data encoded in accordance with the hierarchy coding to image data which has undergone processing designated by the specific command, and transmits the return data to the client. With this arrangement, the client can receive desired image data by one communication between the server and the client.
Claims18
An image communication system including a server which stores image data encoded in accordance with a hierarchy coding, and a client configured to download the image data from the server and display the image data,
- wherein the server
- receives a request from the client,
- determines on the basis of the received request whether a specific command is requested,
- when the specific command is requested, generates return data by adding additional data representing an encoding condition of the image data encoded in accordance with the hierarchy coding to image data which has undergone processing designated by the specific command, and
- transmits the return data to the client.
A server apparatus which stores image data encoded in accordance with a hierarchy coding and transmits the image data to a client, comprising:
- reception means for receiving a request from the client;
- command determination means for determining on the basis of the received request whether a specific command is requested;
- return data generation means for, when the specific command is requested, generating return data by adding additional data representing an encoding condition of the image data encoded in accordance with the hierarchy coding to image data which has undergone processing designated by the specific command;
- and
- transmission means for transmitting the return data to the client.
An image communication method of a server apparatus which stores image data encoded in accordance with a hierarchy coding and transmits the image data to a client, comprising:
- a reception step of receiving a request from the client;
- a command determination step of determining on the basis of the received request whether a specific command is requested;
- a return data generation step of, when the specific command is requested, generating return data by adding additional data representing an encoding condition of the image data encoded in accordance with the hierarchy coding to image data which has undergone processing designated by the specific command;
- and
- a transmission step of transmitting the return data to the client.
A program which controls an information processing apparatus to cause the apparatus to operate as a server apparatus which stores image data encoded in accordance with a hierarchy coding and transmits the image data to a client, the program,comprising program codes corresponding to:
- a reception step of receiving a request from the client;
- a command determination step of determining on the basis of the received request whether a specific command is requested;
- a return data generation step of, when the specific command is requested, generating return data by adding additional data representing an encoding condition of the image data encoded in accordance with the hierarchy coding to image data which has undergone processing designated by the specific command;
- and
- a transmission step of transmitting the return data to the client.
A recording medium which stores a program to control an information processing apparatus and cause the apparatus to operate as a server apparatus which stores image data encoded in accordance with a hierarchy coding and transmits the image data to a client, the program comprising program codes corresponding to:
- a reception step of receiving a request from the client;
- a command determination step of determining on the basis of the received request whether a specific command is requested;
- a return data generation step of, when the specific command is requested, generating return data by adding additional data representing an encoding condition of the image data encoded in accordance with the hierarchy coding to image data which has undergone processing designated by the specific command;
- and
- a transmission step of transmitting the return data to the client.
