Surround Image Generation for Extended Viewing Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visual content signal display systems are complex, costly, and require multiple screens and equipment, limiting their practicality for domestic use and compatibility with existing content signals, while also failing to provide an enhanced viewing experience due to restricted viewing angles.
Innovation Solution
A visual content signal display apparatus that extracts background information from a primary display signal to generate a dynamic surround image, which can be projected onto external surfaces such as walls and ceilings, increasing the viewing angle without the need for additional screens or dedicated equipment, and is compatible with existing content and distribution systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate image sequences are recorded and projected on different screens to create a composite three-dimensional-like image, then the viewing experience is enhanced with extended viewing angles, but the system complexity increases and requires additional equipment
Solution Approach 1:
The patent divides the display system into a primary display for the main content signal and a secondary display area for the generated surround image. This segmentation allows the system to process and display different image sequences separately, with the primary display handling the original content and the secondary display area presenting the generated surround content, thereby achieving extended viewing angles while managing system complexity through functional division
Solution Approach 2:
The patent introduces a processing unit that generates the surround image sequence from the primary content signal. This intermediary processing step creates a derived surround image that can be displayed on the secondary display area, serving as a mediator between the original content and the extended viewing experience, thus enhancing adaptability without requiring multiple independent recording systems
2Adaptability or versatility
If multiple separate image sequences are transmitted and processed to achieve composite display, then the viewing angle is increased, but the required bandwidth increases and distribution resources are consumed
Solution Approach 1:
The patent extracts the essential visual information from the primary content signal to generate the surround image sequence. Instead of transmitting multiple complete independent image sequences, the system extracts key visual elements and characteristics from the primary signal and uses them to create the surround content, significantly reducing the bandwidth requirement while maintaining the extended viewing angle benefit
Solution Approach 2:
The patent generates the surround image sequence by creating a derived copy from the primary content signal rather than requiring completely separate independent sequences. The processing unit creates a correlated surround image that copies essential visual characteristics from the primary signal, reducing distribution resource consumption while achieving the composite display effect
3Adaptability or versatility
If conventional visual content signals are used without modification, then distribution in existing communication systems is enabled, but the enhanced viewing experience cannot be achieved
Solution Approach 1:
The patent implements a dynamic processing approach where the surround image generation is adaptively controlled based on the primary content signal characteristics. The processing unit dynamically adjusts the surround image parameters and generation intensity based on the incoming signal, enabling enhanced viewing experience while managing processing complexity through adaptive rather than static processing requirements
Solution Approach 2:
The patent designs the processing unit to handle multiple functions: it processes the primary content signal, generates the surround image sequence, and manages the coordination between primary and secondary display areas. This multi-functional approach consolidates processing requirements into a single versatile unit, reducing overall system complexity while enabling enhanced viewing experience for existing content signals
4Adaptability or versatility
If more than one screen is used with accurate relative positioning to achieve spatial synchronisation, then the composite picture is achieved, but the cost and practicality for domestic use decreases
Solution Approach 1:
The patent merges the functionality of multiple screens into a coordinated system where the primary display and secondary display area work together under unified control. The processing unit synchronizes the output to both displays, achieving spatial coordination without requiring physically separate independently positioned screens, thereby reducing cost while maintaining spatial synchronization capability for domestic use
Solution Approach 2:
The processing unit serves as an intermediary that coordinates between the content source and the dual display system. It handles the spatial synchronization and timing coordination, eliminating the need for complex mechanical positioning systems and reducing overall system cost while achieving the required spatial synchronisation effect

AI summary
The invention relates to a visual content signal display apparatus (100) comprising a receiver (101) which receives a visual content signal. The receiver (101) is coupled to a primary display processor (103) which is coupled to a primary display (105) and presents the visual content signal thereon. The receiver (101) is further coupled to an extraction processor (107) which extracts background content information from the visual content, signal. The background content information is fed to a secondary display processor (109) which generates a surround image on the basis of the extracted background content information. The surround image comprises visual characteristics corresponding to the visual characteristics of the image of the primary display (105). The display apparatus (100) further comprises a secondary display unit (111), coupled to the secondary display processor (109), and operable to display the surround image on a secondary display area whereby a combined display having an increased viewing angle is achieved. The surround image is preferably projected onto walls and ceiling of a room thereby providing an enhanced viewing experience.
