embodiment

[0076]With reference to FIG. 3 to FIG. 19, the embodiments of the invention and the operations of the invention will be described.

[0077]FIG. 3 shows a first embodiment.

[0078]A stereoscopic image 301 consists of left-eye images (◯) 302 and right-eye images (×) 303 and the left-eye image 302 and the right-eye image 303 respectively correspond to the left-eye image signal input 101 and the right-eye image signal input 102 in FIG. 1. They are arranged on a display as illustrated by 301. Namely, the left-eye images and the right-eye images are arranged alternatively in every other vertical line. The example of FIG. 3 shows the sum of 352 pixels×288 lines including the left-eye images of 176 pixels×288 lines and the right-eye images of 176 pixels×288 lines.

[0079]The stereoscopic image 301 is converted into a first conversion image 304 by the pixel structure converter 104. Namely, the left-eye images of 176 pixels×288 lines are arranged in odd lines by only parallel movement and the right-...

Abstract

A left-eye image signal and a right-eye image signal are supplied to a pixel structure converter of a stereoscopic image pre-processor, and multiplexed, so to form one image, an interlace image is formed by a frame / field converter, encoded in an MPEG format by an MPEG encoding unit, stored into a storage and transmitted outward by a transmitting / recording unit. The encoded stereoscopic image signal received from the outward and reproduced from the storage is decoded by am MPEG decoding unit after going through a receiving / reproducing unit, the interlace image is reproduced, returned to the frame image by a field / frame converter of a stereoscopic image post-processor, and reproduced as the left-eye image signal and the right-eye image signal and output by the pixel structure converter.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a stereoscopic image encoding device for efficiently encoding and transmitting image data including a stereoscopic image, a stereoscopic image and plane image, a stereoscopic image and high resolution plane image, and a stereoscopic image and high resolution added image, and a stereoscopic image decoding device for efficiently receiving and decoding the image data.[0003]2. Description of the Related Art[0004]As the conventional encoding method of a stereoscopic image signal, patented is, for example, “Stereoscopic Video Image Transmission Method and System” disclosed in Japanese Patent Laid-Open (kokai) No. Heisei 11-018111.[0005]The constitutional example of this invention is shown in FIG. 20.[0006]A stereoscopic image 2001 is formed by left-eye images (◯) 2002 and right-eye images (×) 2003. They are disposed on a display as shown by 2001. Namely, left-eye images and right-eye images ar...
