Solution Overview

Problem

Current methods for representing stereoscopic images for multiple observers in virtual environments, such as CAVEs, face challenges in maintaining image quality and are technically complex, particularly when trying to project different images for each observer without impairing image quality or restricting observation angles.

Innovation Solution

The method involves breaking down multicolour image sequences into basic colours, processing these colours in separate data channels, and displaying them sequentially to allow for simultaneous representation of multiple stereoscopic images, which can be achieved using a circuit arrangement with multiple signal inputs and outputs for each basic colour, enabling efficient parallel processing and flicker-free image generation.

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple stereoscopic images are represented simultaneously for different observers, then the system can serve multiple users in virtual environments, but the image quality and brightness are impaired

Engineering Contradiction:
Improvemulti-observer representation capabilityVSAvoidimage brightness
Core Design Contradiction:
Adaptability or versatilityVSIllumination intensity

Solution Approach 1:

The patent segments the image signal into separate basic colour channels (red, green, blue) and processes each channel independently through separate data channels. This allows multiple image sequences to be multiplexed within each colour channel, enabling simultaneous multi-observer representation while maintaining adequate brightness levels by distributing the image data across time slots for each colour component.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a temporal dimension to the colour space processing by sequentially displaying different image sequences for different observers within each basic colour channel. This time-based multiplexing allows multiple observers to be represented simultaneously without compromising the spatial colour information, thereby maintaining image brightness while achieving multi-user versatility.

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

2Adaptability or versatility

If multiple stereoscopic images are represented simultaneously for different observers, then the system can serve multiple users in virtual environments, but the device complexity increases

Engineering Contradiction:
Improvemulti-observer representation capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the complex task of representing multiple stereoscopic images into separate processing stages for each basic colour channel. By segmenting the image data into red, green, and blue components and processing them independently through dedicated data channels, the system achieves multi-observer representation without requiring a completely separate processing path for each observer, thus managing device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a universal processing framework where the same basic colour channel infrastructure can handle multiple image sequences for different observers. The data channels are designed to be multi-functional, capable of carrying images for different observers by time-division multiplexing, thereby reducing the need for dedicated hardware for each observer and lowering overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If conventional projection methods are used for multiple observers, then image separation can be achieved, but the observation angles are significantly restricted

Engineering Contradiction:
Improveobserver differentiation capabilityVSAvoidobservation angle range
Core Design Contradiction:
Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The patent segments the colour information into separate basic colour channels and processes them independently, allowing each channel to carry image data for different observers. This segmentation enables the system to maintain full observation angles for all users by processing colour information separately rather than relying on spatial filtering that would restrict viewing angles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the parameter space from spatial separation (which restricts observation angles) to temporal separation within colour channels. By multiplexing image sequences for different observers within each basic colour channel over time, the system maintains the full angular field of view for all observers while achieving observer differentiation through temporal-multiplexed colour processing.

Inventive Principle:
Principle #35Parameter changes

AI summary

In order to allow a plurality of stereoscopic image sequences to be represented with comparatively good image quality, a method is provided which comprises the following method steps: i. receiving at least two sequences of multi-colored images in parallel; ii. breaking down each image into the basic colors thereof; iii. parallel processing the parts of an image that have been broken down into the basic colors in at least one respective data channel per basic color; iv. simultaneously displaying all parts of an image that have been broken down into the basic colors, wherein sequentially the images of different image sequences follow each other. A circuit assembly that can be used in this context is characterized by at least two signal inputs, wherein each signal input is used as an input for the image signals of an image sequences to be represented and the image signals are based on at least three basic colors, at least one signal output per basic color, wherein the basic color of a signal input is associated with at least one signal output, and a sorting unit, in which the image signals of the image signals that are essentially received via the different signal inputs are broken down into the basic colors thereof and sorted such, at each of the signal outputs, the received signals of a basic color of all signal inputs that are associated with the respective signal output are output.
