Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual adjustment of projector image parameters for different multimedia themes is time-consuming, leading to interruptions and delayed display, which deteriorates the user's visual experience.
Innovation Solution
A data processing system that includes a local computing device for edge computing to capture and analyze projected images, obtaining a text index, and a remote device for central computing to provide parameter settings, allowing synchronous adjustment of projector image parameters with image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual parameter setting is used to adjust picture quality for different multimedia themes, then the picture quality can be adapted to specific contents, but the operation time increases and display is interrupted
Solution Approach 1:
The system enables automatic parameter adjustment by having the projector capture its own projected image, recognize the multimedia theme through image analysis, and autonomously select appropriate display parameters without requiring manual user input for each theme change
Solution Approach 2:
The system implements a feedback loop where the projector captures the projected image, analyzes it to identify the multimedia theme, and uses this information to automatically adjust parameters, creating a closed-loop control system that adapts to content changes
2Adaptability or versatility
If manual parameter setting is performed, then specific picture quality parameters can be adjusted for different themes, but the display continuity is interrupted
Solution Approach 1:
The system performs parameter adjustment in advance by capturing the projected image and analyzing it to identify the theme before the user needs to switch content, allowing parameters to be pre-configured for the upcoming theme change
Solution Approach 2:
The automatic parameter adjustment process occurs continuously in the background during display operation, eliminating interruptions by performing parameter changes asynchronously with the multimedia theme switching
3Productivity
If automatic parameter setting is implemented through image capture and analysis, then parameter adjustment time is reduced, but the device complexity increases
Solution Approach 1:
The projector integrates multiple functions including image projection, image capture, theme recognition, and automatic parameter adjustment into a single device, eliminating the need for separate external devices and reducing overall system complexity
Solution Approach 2:
The system combines the image capture unit, computing unit for theme recognition, and parameter adjustment mechanisms into an integrated assembly within the projector, reducing the number of separate components and simplifying the overall system architecture

AI summary
A data processing system, includes a display device and a local computing device. An image generating unit of the display device performs an image processing operation to generate an image of a multimedia theme, and the image has multiple parameters. An image capturing unit of the local computing device captures the image. A computing unit performs an operation based on the captured image, so as to obtain a text index of the multimedia theme. A second communication unit transmits the text index to the remote device, and receives a set of parameter setting values corresponding to the text index, from the remote device. The display device parses a first command to obtain the parameter setting values, and performs a setting operation according to the parameter setting values to set the parameters of the image.
