A video transcoder includes a deformatting module that generates a deformatted video signal based on a video signal in a source stereoscopic video format, and further based on device data that corresponds to a particular target device. The image displaying apparatus is provided with a light source, a scanning member for two-dimensionally scanning with light from the light source, and an optical system for directing the light deflected by the scanning member for scanning to an observer. The novel polymer that is produced by polymerizing the thiophene derivative is suitable as an electrically conductive material. Upon user invocation of a monitored information capture action, determination is automatically made if the action is redundant. The processes of the present teachings can be performed at low temperature, for example, at ambient temperature, and at atmospheric pressure.
