Image Processing Device Modulating Visual Conditions for Eye Health
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When using small form factor displays, such as those in portable electronic devices, prolonged exposure leads to reduced eyesight acuity due to electromagnetic waves and light, causing dry eyes syndrome and eyesight deterioration due to reduced blinking frequency.
Innovation Solution
An image processing method that periodically changes the visual conditions of content images, such as color, color temperature, or luminance, at a modulation timing to stimulate subconscious blinking, using a modulator to adjust these conditions based on the MacAdam ellipse and average blinking period, ensuring the change is recognizable by the eyes but not by human consciousness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the visual condition of the content image is changed periodically at modulation timing to stimulate subconscious blinking, then eye health is improved and dry eyes syndrome is prevented, but the content image may be distorted or visual quality deteriorates
Solution Approach 1:
The patent applies periodic action by modulating the visual condition of the content image at specific timing intervals corresponding to the average human blinking period. The modulator changes visual conditions (such as luminance, color temperature, or gamma index) periodically to stimulate subconscious blinking, while maintaining the content image recognizable by human eyes but not by human consciousness, thus preventing dry eyes syndrome without causing noticeable distortion.
Solution Approach 2:
The patent employs parameter changes by adjusting specific visual parameters (luminance, color temperature, gamma index) of the content image through the modulator. These parameter changes are controlled to occur within thresholds that prevent excessive distortion of the content image while still being sufficient to stimulate subconscious blinking and prevent eye health issues.
2Extent of automation
If the visual condition is changed to be recognizable by human eyes but not by human consciousness, then subconscious blinking is stimulated, but the change must be carefully controlled to avoid excessive distortion
Solution Approach 1:
The patent implements feedback control by monitoring the visual condition changes and adjusting them based on predefined thresholds. The modulator controls the visual condition changes to remain within acceptable ranges that stimulate subconscious blinking without causing excessive distortion recognizable by human consciousness, thus automating the blinking stimulation while maintaining image quality.
Solution Approach 2:
The patent applies partial action by making visual condition changes that are sufficient to stimulate subconscious blinking but deliberately kept below the threshold of conscious perception. The modulator introduces just enough variation in visual parameters to trigger the desired physiological response without over-modulating to the point of noticeable distortion.

AI summary
An image processing method and image processing device for performing the same are disclosed. In one aspect, the image processing method includes transmitting a content image having a visual condition to a display unit. The method also includes periodically changing the visual condition from a first visual condition to a second visual condition according to a modulation timing such that the content image to be displayed after the modulation timing has the second visual condition different from the first visual condition before commencement of the modulation timing.
