Handheld Game Display Mode Switching for Stereoscopic Blur Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand-held game apparatuses cause user discomfort due to deviations between the optimal and user's viewpoints during stereoscopic image display, leading to blurred images when the device is moved.
Innovation Solution
An information processing program that switches between planar and stereoscopic displays based on movement data, adjusting the virtual camera settings to maintain a clear image by reducing parallax between left and right eye images, and gradually changing display modes to alleviate focus adjustment delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hand-held game apparatus is moved to display a virtual object from various points of view, then the virtual object can be viewed from different angles, but a deviation between the user's point of view and the optimal point of view occurs causing the stereoscopically visible image to be blurred
Solution Approach 1:
The patent applies dynamics by making the display mode adjustable and switchable between stereoscopic and planar views based on the detected movement state. The system dynamically adapts the imaging parameters (parallax amount) according to the acceleration detected by the sensor, allowing the display to transition smoothly between different viewing states to maintain image clarity while enabling viewpoint changes.
Solution Approach 2:
The patent changes the imaging parameters (specifically the parallax amount between left and right eye images) based on the detected acceleration. When movement is detected, the system adjusts the parallax parameter to reduce the deviation between user viewpoint and optimal viewpoint, thereby maintaining image clarity while still allowing virtual object visualization from different angles.
2Ease of operation
If the display mode is switched between stereoscopic and planar views, then user comfort is improved by reducing blur, but focus adjustment delay occurs during the switching process
Solution Approach 1:
The patent uses periodic action by implementing gradual switching between display modes over multiple frames rather than instantaneous switching. The parallax amount is adjusted incrementally across several display cycles, allowing the user's focus to adapt progressively and reducing the perceived focus adjustment delay while still achieving the comfort benefit of reduced blur.

AI summary
A computer-readable storage medium having stored therein an information processing program, an information processing method, an information processing apparatus, and an information processing system which are capable of alleviating a user's uncomfortableness are provided. When a game process is performed by a game apparatus having an LCD on which a display image can be displayed by switching between a planar view display and a stereoscopically visible display, angular velocities of rotations about axes of the game apparatus are detected by using an angular velocity sensor provided in the game apparatus. When at least one of the detected angular velocities of the rotations about the respective axes is greater than or equal to a predetermined angular velocity threshold value, the stereoscopically visible display is switched to the planar view display.
