Abstract: In an image transfer apparatus, a storage unit holds a plurality of data groups each of which includes image data of a screen of a Web page displayed on a virtual browser, an address of the Web page, and setting information about display of the virtual browser performed when the image data is generated. An operation unit searches the data groups for a data group including an address matching an address of a Web page for which a browse request has been transmitted by a terminal apparatus and setting information matching setting information about the corresponding virtual browser. When a matching data group exists, the operation unit reads image data included in the data group from the storage unit and transmits the image data to the terminal apparatus.

Abstract: The server device draws a processing result from software in an image memory, detects an update area containing an update between frames in the image, performs still image compression, and calculates the compression ratio of still image compressed data in the update area. The server device identifies a high-frequency change area, performs moving image compression, and calculates the compression ratio of moving image compressed data. The server device transmits the still image compressed data and the moving image compressed data. The server device stops the moving image compression based on the result of comparing the compression ratio of the moving image compressed data and a compression ratio of still image compressed data in a previous update area is the update area in a previous frame detected before the start of the moving image compression and has been detected at a position associated with the high-frequency change area.

Abstract: A plurality of objects are arranged over a screen and are operable by a plurality of operators. Determinations are made regarding whether a first object, and a second object operated after the first object, are continuously operated or whether a relationship between the first object and the second object is within a predetermined range. An operation setting of the first object is set as an operation setting of the second object in a case where the operations are performed continuously or in a case where the relationship is within the predetermined range.
