Texture Reference Range Adjustment for Display Image Continuity

Solution Overview

Problem

As the resolution of display apparatuses increases, the area represented by one pixel decreases, leading to potential discontinuity in image movement, and improving resolution and frame rate results in larger data sizes and processing burdens, which can impair high-definition image display.

Innovation Solution

An image processing apparatus that acquires movement velocity vectors for each pixel, adjusts reference ranges based on these vectors, samples texel values, and determines pixel values to stabilize image display across varying resolutions and frame rates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the resolution of the display apparatus is increased, then the image definition is improved, but the pixel expressing the same area moves to a position distant from the preceding frame during movement, causing discontinuity

Engineering Contradiction:

Improveimage definitionVSAvoidimage continuity

Core Design Contradiction:

Manufacturing precisionVSStability of the object's composition

Solution Approach 1:

The patent dynamically adjusts the reference range size based on the movement velocity of the texture. When movement velocity is high, the reference range is enlarged to include more texels, which compensates for the larger positional displacement between frames. This dynamic adjustment maintains image continuity while preserving high-resolution display quality.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of reference range size according to movement velocity. By adjusting this parameter adaptively, the system ensures that the sampling area is sufficient to capture the texture information needed for smooth transitions, thereby preventing discontinuity artifacts in high-resolution displays during motion.

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If both the resolution and frame rate are improved, then the image quality and smoothness are enhanced, but the data size of the original image and processing burden increase

Engineering Contradiction:

Improveimage qualityVSAvoidprocessing burden

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies partial filtering by selectively processing only the necessary texels within the adjusted reference range. Instead of uniformly processing all pixels or applying heavy filtering to the entire image, the system focuses computational resources on the relevant texture sampling areas, reducing overall processing burden while maintaining image quality.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The patent applies different processing characteristics to different regions of the image based on local movement velocity. Areas with high movement velocity receive adjusted reference range treatment, while stationary or slowly moving areas use standard processing. This localized approach reduces overall processing complexity while maintaining quality where needed.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If uniform suppression of high-frequency component is performed to eliminate discontinuity, then the discontinuity is reduced, but the intrinsic high-definition image display capability is impaired

AI summary

An input information acquiring section accepts a user's operation. A texture region acquiring section acquires a region of a display image to be presented by use of a texture. A velocity acquiring section acquires for each pixel a movement velocity vector of the texture on a plane of the display image. A texture referencing section adjusts a reference range in an axial direction of the velocity vector in keeping with a magnitude of the movement velocity, before sampling texel values. A pixel value determining section determines a pixel value on the basis of the texel values. An output section outputs the display image.
