Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image-based search is implemented on mobile devices, then user interface capabilities are enhanced, but processing complexity and energy consumption increase
Solution Approach 1:
The patent segments the image processing workflow into distinct modules: image capture, feature extraction, metadata generation, video data correlation, and search query processing. Each module handles a specific aspect of the search process, reducing overall system complexity while maintaining enhanced user interface capabilities.
Solution Approach 2:
The patent introduces metadata as an intermediary layer between raw image data and search queries. Environmental data and capture time data are processed into structured metadata that correlates with video data, serving as a mediator that simplifies the search process and reduces direct processing complexity.
2Measurement precision
If environmental data and video data are correlated using timestamps, then search accuracy is improved, but data processing time increases
Solution Approach 1:
The patent applies preliminary actions by pre-processing environmental data into structured metadata with embedded timestamps before correlation is needed. This advance preparation reduces real-time processing requirements while maintaining high search accuracy through precise timestamp-based matching with video data.

AI summary
In some embodiments, a method of processing image data may include receiving environmental data and associated capture time data from a sensor of a mobile computing device, the capture time data reflecting capture time of the environmental data; processing the environmental data to generate metadata; time stamping the metadata using the capture time data; receiving video data and video time data at a processor; correlating the metadata to the video data using the capture time data and the video time data; receiving a search query; and/or identifying a frame within the video data by performing a search of the metadata using the search criterion.
