Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display methods for video on a digital camera's finder do not adequately consider user convenience in adjusting lightness based on ambient light conditions, leading to visibility issues in high or low brightness environments.
Innovation Solution
A display method and apparatus that uses a sensor to detect ambient light intensity, adjusting the lightness of the displayed video by creating display data that is brighter in high light conditions and darker in low light conditions, with specific gradation corrections for different light levels, and allowing simultaneous display of corrected and uncorrected videos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the lightness of the display video is increased to improve visibility in high brightness environments, then visibility is improved, but the display becomes inappropriate for low light conditions
Solution Approach 1:
The display lightness is made dynamic by automatically adjusting it based on detected ambient light intensity. The system switches between a first display lightness for high brightness environments and a second display lightness for low light environments, allowing the display to adapt its characteristics to match current lighting conditions rather than maintaining a fixed setting.
Solution Approach 2:
The patent changes the lightness parameter of the display video based on ambient light detection. By detecting ambient light intensity and switching between different lightness settings, the system optimizes visibility for the current environment while maintaining versatility across different lighting scenarios.
2Illumination intensity
If gamma correction is applied to brighten the video in high light conditions, then visibility improves, but the video lightness becomes too dark for low light conditions
Solution Approach 1:
The video lightness is dynamically adjusted based on ambient light conditions detected by the sensor. The system automatically applies appropriate lightness settings without requiring manual user intervention, making the operation convenient while adapting to changing environmental lighting.
Solution Approach 2:
The display system performs self-adjustment by automatically detecting ambient light intensity and selecting the appropriate video lightness setting. This eliminates the need for manual user adjustment, allowing the system to serve itself by adapting to environmental conditions autonomously.
3Ease of operation
If a single video lightness setting is used, then the system is simple to operate, but it cannot provide optimal visibility across different ambient light conditions
Solution Approach 1:
The system maintains simplicity in operation while achieving adaptability through self-service functionality. The ambient light sensor automatically detects lighting conditions and triggers appropriate lightness adjustments without requiring user input, combining ease of operation with optimized visibility.
Solution Approach 2:
The system uses feedback from the ambient light sensor to automatically adjust video lightness. The sensor provides continuous information about environmental lighting conditions, and the system responds by selecting the appropriate lightness setting, creating a closed-loop control that maintains optimal visibility.

AI summary
Provided are a display method and a display apparatus capable of appropriately displaying a video on a display in a finder while considering user's convenience.In an embodiment of the invention, video data is acquired by imaging under ambient light, display data based on the video data is created, and a display video corresponding to the display data is displayed on the display in the finder. Then, in a case where intensity of the ambient light is equal to or greater than a first threshold value, lightness of the display video displayed on the display in the finder is made brighter than lightness of a first standard video or in a case where the intensity of the ambient light is equal to or less than a second threshold value, the lightness of the display video displayed on the display in the finder is made darker than lightness of a second standard video.
