Imaging Apparatus Exposure Guide Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging apparatuses make it difficult for users to determine suitable exposure settings, as they often result in unsuitable exposure ranges when users manually set aperture or shutter speed, leading to issues like overexposure, and users struggle to recognize necessary adjustments.
Innovation Solution
An imaging apparatus that displays exposure guide information, including the set parameters and their suitable ranges, allowing users to easily recognize and adjust settings for achieving suitable exposure by calculating target exposure values and displaying the necessary parameter changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the imaging apparatus automatically determines the other exposure condition based on user setting, then exposure control is simplified, but the exposure may fall outside the suitable exposure range
Solution Approach 1:
The imaging apparatus displays exposure guide information showing the relationship between aperture value and shutter speed, allowing users to see whether their settings will produce suitable exposure. This feedback mechanism enables users to adjust settings before taking the shot, ensuring exposure suitability while maintaining operational simplicity.
Solution Approach 2:
The exposure guide display acts as an intermediary between the user's exposure settings and the actual exposure result. It provides a visual representation of the exposure relationship, helping users understand whether their settings will achieve suitable exposure without requiring complex manual adjustments.
2Device complexity
If the imaging apparatus displays only the set exposure state, then the display is simple, but users cannot understand how much settings should be changed for suitable exposure
Solution Approach 1:
The exposure guide adds a new dimension to the display by showing not only the current exposure settings but also the relationship between aperture and shutter speed. This graphical representation provides spatial context that helps users understand adjustment directions without complicating the basic display structure.
Solution Approach 2:
The exposure guide provides preliminary information about exposure suitability before the user takes the shot. By displaying the relationship between settings in advance, users can make informed adjustments without needing to understand complex exposure theory or perform trial-and-error adjustments.
3Adaptability or versatility
If the user sets aperture value to F2 in aperture priority mode, then the user preference is satisfied, but overexposure occurs when subject brightness is too large
Solution Approach 1:
The exposure guide provides immediate feedback when users set aperture values that may lead to overexposure. By displaying the corresponding shutter speed requirements and exposure assessment, users can adjust their aperture settings to achieve both their creative preferences and proper exposure.
Solution Approach 2:
The exposure guide performs preliminary anti-action by warning users before they make settings that would cause overexposure. The display shows whether the combination of user-selected aperture and calculated shutter speed will produce suitable exposure, allowing users to correct settings before shooting.

AI summary
An imaging apparatus includes an imaging unit operable to capture a subject image to generate image data, a controller operable to calculate a target exposure value based on the image data and control exposure based on a first shooting parameter set by a user to obtain the target exposure value, and a display unit operable to provide a display. The controller calculates a first suitable range which is a range of the first shooting parameter for obtaining the target exposure value, and calculates a second shooting parameter based on the target exposure value and the first shooting parameter set by the user. The display unit displays exposure guide information including the first shooting parameter set by the user, information representing the first suitable range, and the calculated second shooting parameter.
