Abstract

This device consists of image sending converter C which converts the image data obtained from at least two video cameras L and R, and image display converter D. C compresses the frame data which are simultaneously obtained from at least two video cameras L and R in parallel by using separate image compressing devices c1 which are synchronized mutually, concatenates the compressed image data, and sequentially converts concatenated data into computer'"'"'s data stream called frame sequential. D is the device which reconfigures above converted data in the top-down split frame sequential format by using image separating device Q and image reconstructing device for stereoscopic image viewing.

Claims

1. The device consisting of image sending converter C which converts the image data obtained from at least two video cameras L and R into the format suitable for computer communications, and image display converter D. C is the device which inputs the frame data obtained from at least two synchronized vide cameras L and R into the separate image compressing device c1, compresses the image in parallel while synchronizing cis mutually, concatenates the compressed image data by using image concatenating device P, and sequentially converts concatenated data into frame sequential to produce single data stream M. D is the device which separates data stream M into above compressed image data obtained from at least two video cameras by using image separating unit Q, inputs sequentially each compressed image data into the image reconstructing device to reconfigure each image frame, and arranges each reconstructed image frame, that is full field image, on the upper and lower subfields of the top-down split screen so that the right and left images are displayed as a single image.

2. A stereoscopic image data processing device comprising:

a first image compressing device to which left image data from a left camera is input;

a second image compressing device to which right image data from a right camera which is synchronized with the left camera is input;

synchronizing means for giving a common timing pulse to both the image compressing devices to synchronize image compression by the first and second image compressing devices; and

a data concatenating device for constructing compressed image data obtained from the first and second image compressing devices as block data, independent, including the left and right image data, and outputting the block data as frame sequential data.

3. The device according to claim 2, wherein the block data includes right and left compressed full filed image data.
