Solution Overview

Problem

Existing 3D video encoding methods using side-by-side, top and bottom, row bi-line, parallax barrier, and lenticular displays waste half of the camera's total pixels, leading to inefficient utilization of camera resolution.

Innovation Solution

A method that synthesizes 3D video using two cameras with half the horizontal pixel resolution of the display, employing an Ichimatsu pattern configuration and pixel supplementation to utilize all camera pixels effectively, allowing 3D image display with 4K or 8K quality using 2K or 4K cameras respectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional 3D video encoding methods (side-by-side, top and bottom, row bi-line, parallax barrier, lenticular) are used, then 3D video can be displayed, but half of the camera's total pixels are wasted

Engineering Contradiction:
Improvepixel utilization efficiencyVSAvoidcamera resolution
Core Design Contradiction:
Loss of energyVSLoss of information

Solution Approach 1:

The patent applies the Ichimatsu pattern to arrange pixels in a two-dimensional grid where odd-numbered pixels from the left camera and even-numbered pixels from the right camera are interleaved both horizontally and vertically. This dimensional arrangement allows all camera pixels to be utilized while maintaining 3D stereo separation, resolving the contradiction between pixel utilization efficiency and camera resolution.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent merges the pixel data from both left and right cameras into a single integrated display buffer using the Ichimatsu pattern. By combining all pixels from both cameras into one coherent structure rather than separating them into distinct regions, the system achieves full pixel utilization while preserving stereo image quality.

Inventive Principle:
Principle #5Merging (Combining)

2Quantity of substance

If two 2K cameras are used to create 3D video, then camera cost is reduced, but display resolution is limited to 2K quality

Engineering Contradiction:
Improvecamera pixel countVSAvoiddisplay image quality
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

By arranging pixels in the Ichimatsu pattern across both horizontal and vertical dimensions, the patent enables two 2K cameras to produce a 4K-quality 3D display. The interleaved arrangement effectively doubles the resolution in both dimensions, allowing lower-cost cameras to achieve higher display quality than traditionally possible.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If all pixels from two cameras are utilized in 3D encoding, then pixel utilization efficiency improves, but complex pixel arrangement patterns are required

Engineering Contradiction:
Improvepixel utilization efficiencyVSAvoidpixel configuration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the display buffer into odd-numbered and even-numbered pixel positions, assigning left camera pixels to odd positions and right camera pixels to even positions. This segmentation provides a systematic and relatively simple method for achieving full pixel utilization without requiring complex arbitrary patterns.

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed is a system capable of synthesizing (encoding) two images taken by two left and right cameras into a 3D video, and viewing the 3D image on a display. The system comprises a computer that uses two cameras with a resolution equivalent to half the number of horizontal pixels of a 3D display, to execute an application program, and arrange each pixel of the two cameras on pixels equivalent to the display. The checkered pattern configuration means that the pixels of the first scan line of the left camera are configured sequentially by skipping one position on the first scan line (odd-numbered rows) of the display, that is, only configured in odd-numbered columns; the pixels of the first scanning line of the right camera skip one position from the second column on the second scanning line (even-numbered row) of the display, that is, only configured in even-numbered.
