Pan-Tilt Camera Thumbnail Acquisition Order
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pan-tilt camera systems with presetting functions face challenges in efficiently displaying multiple presettings, requiring significant time to acquire and display thumbnail images, which hinders quick user operation.
Innovation Solution
A control device with a thumbnail image acquisition order determination unit prioritizes acquiring thumbnail images for presettings that include set values for changing the camera's angle of view, allowing for faster display and enabling users to quickly shift to next operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple presettings are stored in the camera, then the presetting function can provide diverse camera settings, but the client apparatus needs to acquire many thumbnail images which takes much time and prevents quick user operation
Solution Approach 1:
The system performs preliminary action by pre-determining the acquisition order of thumbnail images based on presetting characteristics before user interaction. Thumbnail images corresponding to presettings with angle of view change settings are identified and queued for优先 acquisition, so that when the user accesses the presetting thumbnail display, the images are already being fetched in an optimized sequence rather than waiting for sequential requests
Solution Approach 2:
The system applies local quality by differentiating the treatment of different presettings based on their specific characteristics. Presettings that include angle of view change settings are marked as high-priority and acquire their thumbnail images first, while other presettings follow subsequently. This localized differentiation ensures that the most visually significant presettings are displayed quickest, improving user experience without requiring all presettings to be processed uniformly
2Ease of operation
If the order of thumbnail image acquisition is changed according to user operation, then important thumbnail images can be displayed first, but much time is required until the user can shift to the next operation
Solution Approach 1:
The system implements self-service by automatically determining the acquisition order of thumbnail images based on presetting characteristics without requiring any user input or operation. The control device autonomously identifies which presettings have angle of view change settings and queues their thumbnail images for priority acquisition, eliminating the need for users to manually specify importance or wait for sequential processing while maintaining fast display of critical images
3Productivity
If thumbnail images are acquired sequentially, then the acquisition process is simple, but the display time is extended and user operation is slowed down
Solution Approach 1:
The system applies parameter changes by modifying the acquisition order parameter based on presetting characteristics. Instead of a fixed sequential acquisition sequence, the system dynamically adjusts the acquisition order parameter to prioritize presettings with angle of view change settings. This parameter modification enables faster display of visually significant images while the complexity of determining acquisition order is managed through automated characteristic detection rather than complex user interaction handling

AI summary
A control device includes a thumbnail image acquisition order determination unit configured to determine an order of acquiring thumbnail images, which are images corresponding to presetting information including one or a plurality of set values regarding a camera, in such a manner that a thumbnail image corresponding to a presetting for which at least a set value for changing an angle of view of the camera is included, among the thumbnail images is acquired with priority, a thumbnail acquisition unit configured to acquire the thumbnail images according to the order determined by the thumbnail image acquisition order determination unit, and a thumbnail display control unit configured to display the thumbnail images on a display unit.
