Display Apparatus Local Region Enhancement for Laser Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale public speeches, the use of laser pointers as indicators is ineffective due to the large audience and venue, necessitating an alternative method to enhance specific regions of a projection or display for better visibility.
Innovation Solution
A display apparatus comprising a first display portion, an indication signal receiver, an enhanced region determining portion, and an image processing portion that acquires the position of an indication point, determines an enhanced region, and performs display-enhanced processing to form a second image with adjusted color and highlighting, ensuring the indicated area is prominently displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a laser pointer is used as an indicator in a large-scale speech, then the indication can be provided, but the visibility and effectiveness are poor due to the large audience and venue
Solution Approach 1:
The patent applies local quality by enhancing only the specific region where the laser pointer indicates, rather than the entire display. The image processing portion selectively adjusts color, brightness, or adds highlights to the indicated region, making it stand out locally while leaving other areas unchanged. This resolves the contradiction by providing effective indication in the targeted area without requiring overall high illumination intensity across the large venue.
Solution Approach 2:
The patent utilizes color changes by detecting the laser pointer's position and modifying the color properties of the indicated region. The image processing portion can change the color of the indicated area to a complementary color or enhance its saturation, making it more visible and effective as an indicator. This directly addresses the visibility problem in large venues by making the indicated region stand out through color enhancement.
2Illumination intensity
If the entire display region is enhanced for better visibility, then the visibility improves, but the energy consumption and processing load increase significantly
Solution Approach 1:
The patent implements local quality enhancement by applying display enhancement only to the specific region indicated by the laser pointer, rather than the entire display. The image processing portion selectively processes only the indicated region's pixels, reducing the computational load and energy consumption compared to enhancing the whole display. This resolves the contradiction by providing improved visibility where needed while minimizing overall energy usage.
Solution Approach 2:
The patent applies partial action by enhancing only the necessary portion of the display (the indicated region) rather than the entire display area. The image processing portion processes a fraction of the total pixels, specifically those in the indicated region, thereby reducing processing load and energy consumption while still achieving the visibility improvement goal for the critical area.
3Illumination intensity
If the entire display region is enhanced for better visibility, then the visibility improves, but the device complexity and processing requirements increase
Solution Approach 1:
The patent reduces processing complexity by applying enhancement only to the local indicated region rather than the entire display. The image processing portion receives the original image and the indicated region coordinates, then selectively processes only those specific pixels. This localized approach significantly reduces the number of pixels that need processing, simplifying the device requirements compared to full-display enhancement.
Solution Approach 2:
The patent implements partial processing by enhancing only the indicated region instead of the complete display area. The image processing portion processes a subset of pixels (those in the indicated region) rather than all pixels, thereby reducing computational complexity and device requirements while still achieving the visibility improvement objective.
