Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses lack good operability for setting autobracketing values using touch panels, which complicates user interaction and efficiency in adjusting exposure compensation and autobracketing settings.
Innovation Solution
An imaging apparatus with a touch detection unit that controls indicators on a display to adjust the width between reference and autobracketing values by detecting touch operations, allowing users to easily set autobracketing values by moving their finger in specific directions on the touch panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional touch panel operations are used for setting autobracketing values, then the device can perform basic settings, but the operability is poor and user interaction is complicated
Solution Approach 1:
The touch panel display is segmented into multiple functional areas: a setting area for autobracketing width, a reference value indicator area, and a bracketing value indicator area. This segmentation allows users to interact with specific regions to perform different operations, simplifying the overall operation complexity while maintaining comprehensive functionality.
Solution Approach 2:
Visual indicators (reference value indicator and bracketing value indicator) are introduced as intermediaries between the user and the autobracketing settings. These indicators provide intuitive feedback about the current settings and changes, making the operation more understandable and easier to control without requiring users to interpret complex numerical values directly.
2Measurement precision
If precise two-point touch operations are required for setting autobracketing, then accurate settings can be achieved, but user experience deteriorates due to operation difficulty
Solution Approach 1:
The system dynamically responds to touch operations within the setting area by detecting the direction of touch movement and automatically adjusting the autobracketing width accordingly. This dynamic adjustment mechanism eliminates the need for precise two-point touch operations, as users only need to perform simple directional touches within a single continuous area, significantly improving operational ease while maintaining setting precision.
Solution Approach 2:
The system performs automatic calculation and adjustment of autobracketing values based on touch operation direction. Instead of requiring users to manually input precise values or perform complex two-point touches, the system serves itself by interpreting the touch direction and automatically computing the appropriate width adjustment, thereby achieving high precision with simple user actions.
3Manufacturing precision
If autobracketing width is adjusted through multiple discrete steps, then precise control is possible, but operation efficiency decreases
Solution Approach 1:
The system prepares multiple preset autobracketing width options in advance, and users can quickly switch between these pre-calculated values by simply changing touch direction. This preliminary preparation of options allows users to make efficient adjustments without performing multiple discrete step-by-step operations, thereby improving productivity while maintaining precise control over the autobracketing width.

AI summary
An imaging apparatus includes a touch detection unit configured to detect a touch operation on a display unit, a display control unit configured to control display of an indicator indicating a reference value in an autobracketing shooting and an indicator indicating a bracketing value in the autobracketing shooting, a control unit configured to perform control to increase a width between the reference value and the bracketing value to be set when the touch detection unit detects a touch operation moving in a first direction while keeping touching a setting area for setting the bracketing value on the display unit and to decrease the width when the touch detection unit detects a touch operation moving in a second direction opposite the first direction while keeping touching the setting area, and a bracketing value setting unit configured to set the bracketing value based on the width.
