An image signal composed of sequential frames is input to a 3-dimensional image creating apparatus, frame by frame. A controller ( 102 ) designates the presence/absence of reduction, the presence/absence of joining and 2D select. An image converter ( 101 ) creates image data in the format designated by the presence/absence of reduction and the presence/absence of joining. A 3D information creator( 103 ) creates 3D information necessary for displaying the image as a 3-dimensional image by formatting the presence/absence of reduction, the presence/absence of joining and 2D select. A multiplexer( 104 ) converts image data and 3D information in a predetermined format and outputs them to the outside. In this way, it is possible to make the image data for 3-dimensional display versatile and select an arbitrary viewpoint image efficiently.
