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.

The invention discloses a multi-curvature rear view mirror lens, pertaining to the technical field of auto parts. A mirror surface of the lens is a multi-curvature free curved surface combined by multiple small mirror surfaces. Curvature radii are different among the multiple small mirror surfaces and different directions of each small mirror surface. The curvature radius of an overall mirror surface firstly decreases and then increases from the top to the bottom. So does the change rate of the curvature radius. The curvature radius of the overall mirror surface firstly decreases and then increases from the left to the right. So does the change rate of the curvature radius. The multi-curvature rear view mirror lens has following beneficial effects: the curvature radius of the overall mirror surface of the multi-curvature rear view mirror lens keeps changing so that each small mirror covers a small area in the approximation to a point; a smooth surface is achieved after splicing of the multiple small mirror surfaces; uniform imaging is obtained by mirror surfaces without hopping so that no interference is caused to riding of a driver and a field range is broad and image distortion is less; and the multi-curvature rear view mirror lens is simple in structure and low in cost.
