Abstract
In the case where an image of a document or the like is taken by an economical camera in a TV conference system and the image is transmitted and received through a communication line, when an image of the whole of the document is taken, small characters are defaced and illegible, and, when an imaging operation is performed with a resolution at which characters are readable, it is impossible to take an image of the whole of the document. An image F at time T which is taken while moving an imaging section is captured into an image storing section and a feature point extracting section. The feature point extracting section extracts feature points of the image F . An image F at time T when the subsequent frame is started is captured into the image storing section and the feature point extracting section. The image F in a region designated by a search range determining section, and the feature points of the image F are subject to a calculation in a correlation calculating section, to obtain a motion amount, and then a high-resolution image is synthesized.
