Display Control Apparatus for Stereoscopic Cursor Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional display technologies face difficulties in displaying operation objects like cursors as normal two-dimensional images within areas where stereoscopic displays are performed, leading to reduced operability and increased process loads due to the need for cursor compliance with stereoscopic processes.
Innovation Solution
A display control apparatus and method that includes a display controller and a switch, which enables the cursor to be hidden and re-displayed in two-dimensional mode when it enters a stereoscopic display area, allowing for seamless operation without requiring stereoscopic processing, and re-positions the cursor on title or control bars after a predetermined time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a special process for enabling the stereoscopic display is performed in the area where the stereoscopic image is displayed, then the stereoscopic display function is improved, but it becomes difficult to display operation objects such as cursors as normal two-dimensional images
Solution Approach 1:
The display screen is divided into a stereoscopic display area and a non-stereoscopic display area. The controller selectively applies stereoscopic processing only to the stereoscopic display area, while operation objects like cursors are displayed in the non-stereoscopic area as normal two-dimensional images. This segmentation allows both stereoscopic imaging and conventional operation object display to coexist without interference.
Solution Approach 2:
Different display modes are applied to different regions of the screen. The stereoscopic display area receives specialized processing for three-dimensional imaging, while the non-stereoscopic area maintains standard two-dimensional display characteristics. This local differentiation enables the cursor to be displayed as a normal 2D image in the non-stereoscopic area while preserving stereoscopic functionality in the designated area.
2Loss of information
If the cursor is displayed in the area where the stereoscopic display is performed, then the cursor visibility is improved, but the processing load increases due to the need for cursor compliance with stereoscopic processes
Solution Approach 1:
The cursor display function is extracted from the stereoscopic display area and placed in the non-stereoscopic display area. This extraction eliminates the need to apply complex stereoscopic processing to the cursor, thereby reducing the overall processing load while maintaining cursor visibility in a region where standard 2D display rules apply.
3Adaptability or versatility
If the cursor moves to the stereoscopic display area, then the cursor can interact with stereoscopic content, but abnormal display occurs and operability is reduced
Solution Approach 1:
By segmenting the display area into stereoscopic and non-stereoscopic zones, the system establishes clear boundaries for cursor behavior. The cursor operates reliably in the non-stereoscopic area where 2D display rules apply, while interaction with stereoscopic content is facilitated through the defined interface between the two areas, preventing abnormal display conditions.

AI summary
According to one embodiment, a display control apparatus includes: a display controller configured to control display of stereoscopic display data that is based on pieces of image information which have a mutual parallax and an operation object that moves in accordance with a user's operation, in a screen; and a switch module configured to disable display of the operation object if the operation object moves to an area where the stereoscopic display data is displayed in the screen.
