Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD THEREOF, AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/164821
Kind Code:
A1
Abstract:
An objective of the present invention is to allow, in a display by picture-in-picture protocol in a full-duplex system of videophone or web chat over a network, compression as a one-frame image by image processing, thus allowing conservation of network bandwidth. By receiving display location information of a child screen from a corresponding image processing device, and carrying out image processing based on the child screen location information, an image process of the child screen location is conducted by the image processing device according to display information of a picture-in-picture protocol of a corresponding device. Furthermore, by converting, as the image process, the image of the child screen location to highly compressible data, encoding the generated image and creating compressed data, data volume and network bandwidth is reduced.
