Dog Display Filter Enhancing Blue Visibility for Canine Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies fail to effectively showcase images to dogs due to their unique visual characteristics, as they have two types of cone cells and distinguish colors differently than humans, particularly recognizing red and green as yellow and being highly sensitive to blue wavelengths.
Innovation Solution
A display apparatus with a dog filter that adjusts input image data by adding a compensation value to the blue grayscale and subtracting from the red and green grayscale values to enhance the blue ratio, converting the image data to reflect canine visual sensitivity, thereby increasing the blue ratio and decreasing the red and green ratios to improve image recognition for dogs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard display technology is used, then images are optimized for human vision, but dogs cannot effectively recognize the displayed content due to their different visual characteristics
Solution Approach 1:
The patent applies local quality by adjusting specific color channels (increasing blue, decreasing red and green) in the image data while leaving other aspects unchanged. This targeted modification optimizes the image for canine visual sensitivity without completely redesigning the entire display system.
Solution Approach 2:
The patent changes the color parameter values in the image data by applying a filter that modifies the blue grayscale value (increasing it) and red/grreen grayscale values (decreasing them). This parameter transformation converts human-optimized images into dog-optimized images while maintaining the same display hardware.
2Measurement precision
If image data is adjusted to enhance blue visibility for dogs, then canine color sensitivity is improved, but the original color accuracy for human viewing is altered
Solution Approach 1:
The patent applies preliminary action by pre-processing the image data with a dog filter before display. This converts the image into a format optimized for canine vision in advance, allowing the display system to present appropriately adjusted content without requiring real-time modification during viewing.
Solution Approach 2:
Instead of trying to make the display hardware itself adaptive to different species, the patent inverts the approach by modifying the image data to match the receiver's characteristics. This software-based inversion allows the same hardware to serve both human and canine viewers effectively.

AI summary
A display apparatus for a dog includes a display panel including pixels, a dog filter which generates dog image data based on input image data and determine a second blue grayscale value of the dog image data by adding a first blue grayscale value of the input image data and a compensation value and a display panel driver which generates data voltages based on the dog image data and apply the data voltages to the pixels.
