Dynamic Image Blurring for Focus Target Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In three-dimensional space image processing, users face difficulty in recognizing focusing targets when the viewpoint or viewing direction changes rapidly, leading to blurred and indistinct images, making it hard to capture or maintain focus on specific objects.
Innovation Solution
An image processing program that generates a reference image, determines a target area, calculates blurring values based on movement and depth, and applies blurring processing to areas outside the target area, ensuring the focus point remains clear by adjusting the blurring degree according to the movement and depth values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the viewpoint or viewing direction changes rapidly in three-dimensional space, then the responsiveness and dynamic display capability are improved, but the user's ability to recognize and maintain focus on specific objects deteriorates
Solution Approach 1:
The patent applies different quality treatments to different regions of the displayed image. Specifically, the area around the focus point is kept clear and sharp, while other areas are blurred to varying degrees. This local differentiation ensures that even when the viewpoint moves rapidly, the user can still clearly identify the focus target while the rest of the scene adapts to the motion, resolving the contradiction between dynamic responsiveness and focus recognition.
2Productivity
If the entire image content changes when the viewpoint moves, then the real-time display capability is improved, but the stability of focus target identification deteriorates
Solution Approach 1:
The patent maintains stability of the focus target by applying a different rendering quality to the focus area compared to the rest of the image. The focus region is rendered with high stability and clarity regardless of viewpoint changes, while other regions are rendered with motion-adapted blurring. This allows real-time image generation to proceed efficiently while preserving focus target stability.
Solution Approach 2:
The patent introduces a blur effect as an intermediary element between the moving viewpoint and the displayed image content. This blur acts as a mediator that smooths out the abrupt changes in the entire image content, allowing the focus point to remain stable and recognizable even as the viewpoint moves and the overall scene changes in real-time.
3Speed
If high-speed viewpoint movement is implemented, then the dynamic response capability is improved, but the image clarity and focus maintenance deteriorate
Solution Approach 1:
The patent implements spatially varying image quality where the focus region maintains high clarity and detail even during high-speed viewpoint movement, while peripheral regions are intentionally blurred. This local quality differentiation allows the system to achieve high dynamic response speeds without sacrificing the manufacturing precision (image clarity) of the focus target, as the computational resources are concentrated on maintaining clarity only where needed.

AI summary
The game apparatus generates an image of a virtual space viewed from a virtual camera as a reference image. The game apparatus then calculates a blurring value indicative of a blurring degree of the image. The blurring value is calculated so as to become greater than a reference value in the case where a movement amount of the virtual camera is equal to or greater than a predetermined amount, and to become smaller than the reference value in the case where the movement amount of the virtual camera is smaller than the predetermine amount. The game apparatus blurs an image outside a predetermined area of the reference image such that the blurring degree increases in accordance with an increase of the blurring value. The predetermined area is determined, from among an image area of the reference image, so as to include a position of a focus point of the virtual camera. Accordingly, a blurred image is displayed on a display apparatus.
