Digital Camera Image Processing Priority Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital cameras experience long wait times when switching from imaging mode to reproduction mode during continuous capture, as image data is processed sequentially, leading to delayed display of the last recorded image.
Innovation Solution
The digital camera employs a controller to set priorities for image processing based on time stamps and resource usage, allowing for efficient processing and display of image data, thereby reducing wait times during reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If image data is processed sequentially in time series, then processing is simple and systematic, but wait time for reproducing the last image is long
Solution Approach 1:
The patent applies preliminary action by setting processing priorities for all image data before reproduction begins. The controller assigns priority levels based on capture time stamps, ensuring that the most recent images are processed first. This pre-establishment of processing order eliminates waiting time during reproduction without requiring complex real-time scheduling mechanisms.
Solution Approach 2:
The patent implements dynamics by making the processing order adaptive rather than fixed. The priority assignment system dynamically determines which images to process first based on their capture time, allowing the system to flexibly adjust processing sequences. This dynamic approach resolves the contradiction by enabling fast reproduction of recent images while maintaining a systematic processing framework.
2Quantity of substance
If continuous capture is executed, then more images are recorded, but processing time for all images increases
Solution Approach 1:
The patent applies segmentation by dividing the processing task into priority-based segments. Instead of processing all image data uniformly, the system segments processing into multiple priority levels, with the most recent images receiving highest priority. This allows the system to handle large quantities of continuously captured images efficiently by focusing computational resources on the most important data first.
Solution Approach 2:
The patent uses parameter changes by introducing priority levels as a new parameter that determines processing order. The controller assigns different priority values to image data based on capture time, transforming the processing approach from sequential to priority-driven. This parameter change enables the system to manage large volumes of continuous capture data without proportionally increasing total processing time.
3Ease of operation
If the last captured image is displayed first, then user convenience is improved, but processing order becomes non-sequential
Solution Approach 1:
The patent applies self-service by enabling the image data themselves to determine their own processing priority through embedded time stamp information. Each image carries its capture time metadata, which the controller automatically uses to assign processing priorities without requiring external intervention or complex sorting algorithms. This self-service mechanism achieves user-convenient display order while maintaining simple processing management.
