3D Image Disparity Adjustment for Display Type
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional image generating technologies fail to adjust the disparity of 3D images according to the type of display, leading to discomfort for viewers, especially when the disparity exceeds 3% of the screen width, limiting the enhancement of the sense of reality.
Innovation Solution
A device and method that identify the type of display and generate three-dimensional images with disparity tailored to the specific display, considering factors like head-mounted displays, 3D televisions, screen configuration, and user eye distance to optimize the sense of reality without discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the amount of disparity of a displayed three-dimensional image is increased to enhance the sense of reality, then the sense of reality is improved, but the viewer feels more uncomfortable due to increased burden on the eyes
Solution Approach 1:
The patent changes the disparity parameter based on the display type. For head-mounted displays, a larger disparity (e.g., 6% or more of horizontal screen width) is applied to enhance the sense of reality, while for 3D televisions, a smaller disparity (e.g., 3% or less) is used to reduce viewer discomfort. This parameter adaptation resolves the contradiction by optimizing the disparity level according to the specific display characteristics.
Solution Approach 2:
The patent applies different disparity settings tailored to specific display types (head-mounted displays versus 3D televisions). Each display type receives a locally optimized disparity value suited to its characteristics, allowing the sense of reality to be maximized for head-mounted displays while maintaining comfort for 3D televisions.
2Device complexity
If a fixed disparity amount is used for all displays to simplify the generating process, then the device complexity is reduced, but the sense of reality cannot be optimized for different display types
Solution Approach 1:
The patent introduces dynamic adjustment of the disparity parameter based on the detected display type. The disparity amount is not fixed but dynamically changed according to whether the display is a head-mounted display or a 3D television, enabling optimization of the sense of reality without significantly complicating the generating process.
Solution Approach 2:
The patent incorporates feedback from display type identification to adjust the disparity parameter. The system detects the display type and uses this information to determine the appropriate disparity level, creating a feedback loop that optimizes the three-dimensional image generation for different display characteristics.

AI summary
A three-dimensional image generating device, a three-dimensional image generating method, a program, and an information storage medium provide for the ability to set the amount of disparity of a generated three-dimensional image to the amount of disparity according to the kind of display on which this three-dimensional image is displayed. A set value identifying section identifies the kind of display to which a three-dimensional image is output. An image generating section generates the three-dimensional image with the amount of disparity according to the kind of the display identified.
