Camera Menu Adaptation by Lens Type and Usage Count
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In interchangeable lens type digital cameras, the increasing number of imaging functions leads to complex setting menus, making it difficult for users to find and utilize the desired settings, especially when different lenses are mounted, resulting in poor usability.
Innovation Solution
The camera system includes a lens mounting section, a lens type detection mechanism, a controller, and a menu display section that adjusts the setting menu based on the lens type and usage statistics, such as mounting operations and imaging operations, to provide a tailored and simplified menu for the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If setting menus are changed in accordance with the specific information of the interchangeable lens, then the imaging functions can be optimized for the mounted lens, but the usability deteriorates when a different lens is mounted because the setting menus become different from what the user is familiar with
Solution Approach 1:
The system performs preliminary actions by detecting the lens type and predicting the user's familiarity level before displaying the setting menu. Based on this prediction, the system pre-adjusts the menu to show either detailed options for unfamiliar lenses or familiar simplified options for known lenses, preventing usability deterioration before it occurs.
Solution Approach 2:
The setting menu is made dynamic by continuously adapting its content based on the detected lens type and the user's familiarity level. The menu structure changes dynamically - showing more or fewer options, reorganizing item sequences, and adjusting detail levels according to real-time detection results, rather than using a fixed menu structure.
2Adaptability or versatility
If the number of setting items in the setting menu is increased to provide more imaging functions, then the imaging capabilities are enhanced, but the ease of operation deteriorates because it becomes difficult to find the desired setting items
Solution Approach 1:
The setting menu is segmented into different sections or groups based on the detected lens type and user familiarity. Instead of presenting all setting items at once, the menu is divided into relevant subsets - showing only the most important items first, grouping related settings together, and hiding less relevant options, making it easier to find desired settings among many available functions.
Solution Approach 2:
Different parts of the setting menu are given different qualities or levels of detail based on local needs. The menu structure is customized locally for each lens type and user context - some sections show detailed technical options while others show simplified controls, with the quality and depth of each menu section adapted to match the specific imaging scenario.

AI summary
A camera main body includes a mount, a solid-state imaging element, a main body controller, a main body side storage section, and a rear surface display section. In the mount, a plurality of types of interchangeable lenses are selectively mounted. The main body controller acquires a lens type of each interchangeable lens mounted on the mount, counts the number of mounting operations and the number of imaging operations for each lens type of the interchangeable lens, and stores the result in the main body side storage section. In a case where the interchangeable lens is mounted on the mount, the main body controller changes a setting menu to be displayed on the rear surface display section in accordance with the lens type acquired from the interchangeable lens, and the number of mounting operations and the number of imaging operations corresponding to the lens type.
