Client Terminal Server Overhead View Image Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital cameras cannot display images from viewpoints significantly different from the user's actual position, limiting the ability to show bird's eye views or other overhead perspectives, and existing technologies do not account for user-positioned viewpoints in image display control.
Innovation Solution
A client terminal and server system that determines whether an overhead view image is associated with a user-indicated position and controls the display to show the corresponding overhead view image, using GPS and image databases to retrieve and display images from specific altitudes and positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a digital camera displays only images within the optically visible range from the user's actual position, then the camera maintains simple display control, but the camera cannot display overhead view images or images from significantly different viewpoints
Solution Approach 1:
The patent introduces a server as an intermediary between the digital camera and overhead view image data. The server receives position information from the camera, determines appropriate overhead view images, and transmits them back. This mediator approach allows the camera to display diverse viewpoints without directly handling the complexity of viewpoint determination and image retrieval
Solution Approach 2:
The system divides the viewpoint display function into separate modules: the digital camera captures current position and transmits position information, the server determines and provides overhead view images, and the camera displays the received images. This segmentation allows each component to focus on its specific task, reducing overall system complexity while enabling versatile viewpoint display
2Ease of operation
If a digital camera displays images from significantly different viewpoints such as bird's eye views, then the user experience is enhanced, but the display control becomes more complex as it must account for position and viewpoint transformations
Solution Approach 1:
The server performs self-service by automatically determining which overhead view image to provide based on position information received from the camera. The server independently handles viewpoint determination and image selection without requiring complex processing at the camera end, thus enhancing user experience while keeping the camera's display control relatively simple
Solution Approach 2:
The system implements a feedback loop where the camera transmits position information to the server, the server determines the appropriate overhead view image based on this feedback, and then provides the image back to the camera for display. This feedback mechanism enables automatic adaptation to user position and viewpoint requirements

AI summary
There is provided a client terminal including a determination unit configured to determine whether an overhead view image is associated with a position indicated by a user, and a display control unit configured to perform control so that the overhead view image is displayed on a display unit in accordance with a determination result obtained by the determination unit.
