Imaging Device Diopter-Based Display Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices struggle to adjust display content on their configuration screens to match the eyesight of photographers, particularly when the diopter value of the finder unit does not align with the photographer's hyperopia, leading to difficulties in viewing images or characters.
Innovation Solution
An imaging device with a diopter configuration manipulation unit, a number-of-configurations storage unit, and a configuration screen changing unit that adjusts the display content based on the diopter value and configuration frequency, including options such as erasing the configuration screen, reducing character count, changing text to icons, enlarging configuration items, and displaying attention prompts, to better align with the photographer's eyesight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display size of images or characters on the rear display unit is increased to match hyperopia, then the visibility for hyperopic photographers is improved, but the usability deteriorates because the configuration screen becomes difficult to view and operate
Solution Approach 1:
The patent applies dynamics by making the display characteristics changeable based on the configured diopter value. The display control unit dynamically adjusts whether to increase display size or maintain normal configuration screen display, allowing the system to adapt between different viewing conditions and operational states.
2Illumination intensity
If the configuration screen is displayed with increased size to match hyperopia, then the visibility is improved, but the configuration screen cannot be properly viewed and operated
Solution Approach 1:
The patent applies parameter changes by modifying display parameters (display size, character size) based on the diopter value configured by the user. The display control unit changes these parameters dynamically according to the diopter setting, allowing the display to adapt to different eyesight conditions without adding complex hardware.
3Adaptability or versatility
If the display content is adjusted to match the diopter value, then the eyesight compatibility is improved, but the system complexity increases due to additional control mechanisms
Solution Approach 1:
The patent applies universality by making the rear display unit serve multiple functions: it displays both the configuration screen and subject images, and it adapts its display characteristics based on the diopter value. This multi-functionality allows a single display unit to accommodate different viewing conditions without requiring separate display systems.
Solution Approach 2:
The patent applies feedback by using the diopter value configured by the user as input to control the display characteristics. The display control unit receives feedback from the diopter configuration and automatically adjusts the display parameters accordingly, creating a closed-loop system that adapts to user needs.

AI summary
A camera body includes a mount, a solid-state imaging element, a body control unit, a diopter value detection unit, a number-of-configurations storage unit, a rear display unit, and a finder unit. An interchangeable lens is attached to the mount. The body control unit counts the number of configurations by the diopter adjustment dial for each diopter value of the finder unit configured by the diopter adjustment dial and stores the number of configurations in the number-of-configurations storage unit. In a case where the diopter value of the finder unit has been configured by the diopter adjustment dial, the body control unit changes a configuration screen to be displayed on the rear display unit according to the number of configurations stored in the number-of-configurations storage unit.
