Digital Camera Manual Mode Settings Change Alert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users operating in manual mode of digital photographing apparatus often forget or are unaware of changes in photographing variables such as white balance and brightness between the time settings are made and when photos are taken, leading to unwanted images due to difficulty in confirming illumination differences on the LCD display.
Innovation Solution
A method and apparatus that monitor and compare initial and subsequent automatic values of photographing variables like white balance and brightness, generating an alarm signal if they fall outside identical ranges, ensuring users are notified of changes and allowing for adjustments to maintain desired settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual mode is used to personally set photographing variables, then flexibility and control over photographing conditions are improved, but users may forget or be unaware of changes in settings over time, leading to unwanted images
Solution Approach 1:
The system continuously monitors current photographing conditions and compares them with the conditions when variables were set, providing feedback to the user through notifications when significant changes are detected. This feedback mechanism ensures users are aware of environmental changes that may affect image quality while maintaining manual control flexibility.
Solution Approach 2:
The system performs preliminary comparison of photographing conditions before the user takes a photo, detecting changes in illumination and other variables in advance. This allows users to adjust settings proactively before capturing the image, preventing unwanted photos rather than correcting them afterward.
2Device complexity
If only LCD window display is used to confirm settings, then device complexity is reduced, but delicate differences in illumination conditions cannot be confirmed accurately
Solution Approach 1:
The system introduces an intermediary comparison mechanism that processes raw sensor data about illumination conditions and translates it into meaningful notifications for the user. This intermediary layer enhances the information available to users without adding complex display hardware, maintaining simplicity while improving detection accuracy.
3Ease of operation
If photographing variables are set a long time before taking photos, then users have time to adjust settings carefully, but users are more likely to forget the settings and environmental changes
Solution Approach 1:
The system provides periodic feedback to users about current photographing conditions compared to when settings were established. This continuous monitoring and notification system prevents information loss over time by reminding users of environmental changes that may affect their manually set variables.

AI summary
A digital photographing apparatus which, when operating in a manual mode for externally manipulating and setting photographing variables, determines when a photo is to be taken, and if photographing conditions are changed from those which occurred when photographing variables were set, notifies a user of the change so that a photo can be taken with desired photographic variables. A method of controlling a digital photographing apparatus to perform these operations is also provided.
