Abstract

Claims (27)

1 . An image generation system functioning as a cloud browser and capable of communicating with a communication apparatus, the image generation system comprising:

one or more memories; and

one or more processors in communication with the one more memories,

wherein the one or more processors and the one more memories are configured to:

receive an operation instruction with respect to a web page from the communication apparatus, wherein the operation instruction includes information indicating an attribute of the operation instruction;

transmit, to the communication apparatus, predetermined information when the operation instruction is a press for file selection, wherein the predetermined information includes information of a pressed element and information indicating being in a file selection mode;

receive file structure information transmitted from the communication apparatus based on the information indicating being in the file selection mode;

reproduce a visual representation of a file structure that corresponds to that of the communication apparatus by expanding a folder and generating a group of files based on the file structure information, wherein the group of files are a group of zero-byte files, and transmit the visual representation to the communication apparatus;

receive, from the communication apparatus, information of coordinates of a press of a user with respect to the visual representation;

identify information on a file present at the coordinates of the press;

transmit the information of the identified file to the communication apparatus, wherein the information of the identified file includes a file name;

receive data of the identified file transmitted from the communication apparatus;

replace the group of zero-byte data files with the received data of the identified file; and

generate a rendering result that reflects the received data of the identified file and transmit the rendering result to the communication apparatus.

2 . The image generation system according to claim 1 , wherein the one or more processors and the one more memories are further configured to delete information received from the communication apparatus when a user terminates use of the image generation system via the communication apparatus.

3 . A method of operating an image generation system functioning as a cloud browser and capable of communicating with a communication apparatus, the method comprising:

receiving from the communication apparatus an operation instruction with respect to a web page, wherein the operation instruction includes information indicating an attribute of the operation instruction;

transmitting, to the communication apparatus, predetermined information when the operation instruction is a press for file selection, wherein the predetermined information includes information of a pressed element and information indicating being in a file selection mode;

receiving file structure information transmitted from the communication apparatus based on the information indicating being in the file selection mode;

reproducing a visual representation of a file structure that corresponds to that of the communication apparatus by expanding a folder and generating a group of files based on the file structure information, wherein the group of files are a group of zero-byte files, and transmitting the visual representation to the communication apparatus;

receiving, from the communication apparatus, information of coordinates of a press of a user with respect to the visual representation;

identifying information on a file present at the coordinates of the press;

transmitting the information of the identified file to the communication apparatus, wherein the information of the identified file includes a file name;

receiving data of the identified file from the communication apparatus;

replacing the group of zero-byte data files with the received data of the identified file;

and

generating a rendering result that reflects the received data of the identified file and transmitting the rendering result to the communication apparatus.
