Image Capturing Apparatus Dual Increment ISO Sensitivity Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in setting desired ISO sensitivity in image capturing apparatuses due to limitations in ISO sensitivity step number settings, leading to unintended lower resolution images when trying to set upper or lower limit values.
Innovation Solution
An image capturing apparatus with a selection method that allows users to choose between two numerical value increments for sensitivity settings, enabling selection of sensitivities not corresponding to the initial increment, thereby allowing easier setting of desired ISO sensitivity regardless of the step number setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ISO sensitivity step number setting is used to select sensitivity options, then the sensitivity can be selected from a fixed set of values at a first numerical value increment, but the desired sensitivity value (especially upper or lower limit values) cannot be selected if it does not correspond to the step number increment
Solution Approach 1:
The patent applies dynamics by making the sensitivity selection system adaptable and flexible. The system dynamically switches between two selection methods: a first method for selecting from sensitivities at a first numerical value increment (e.g., 100, 200, 400, 800), and a second method for selecting from sensitivities at a second numerical value increment (e.g., 50, 100, 200, 400). This dynamic adaptability allows the system to accommodate different user needs and desired sensitivity values without being constrained by a fixed step number setting.
Solution Approach 2:
The patent implements parameter changes by allowing the user to switch between different numerical value increments for sensitivity selection. The system changes the parameter of numerical value increment from a fixed first increment to a different second increment, enabling the selection of sensitivity values that would otherwise be unavailable. This parameter change resolves the contradiction by expanding the range of selectable sensitivity values while maintaining the structured selection approach.
2Adaptability or versatility
If the user changes the ISO sensitivity step number setting to access limit values, then the desired sensitivity can be selected, but the operation becomes more complex and time-consuming
Solution Approach 1:
The patent applies universality by creating a multi-functional sensitivity selection system that can operate in two different modes. The first selection method provides a simplified interface for common sensitivity values at a first numerical increment, while the second selection method provides access to additional values at a second numerical increment. Both methods are integrated into a single unified selection interface, eliminating the need for users to change the ISO sensitivity step number setting and allowing direct selection of any desired sensitivity value regardless of the step number configuration.
3Ease of operation
If only one selection method is provided, then the interface is simple, but the user cannot select sensitivities that do not correspond to the fixed numerical increment
Solution Approach 1:
The patent resolves this contradiction by implementing a dynamic selection interface that can switch between two different numerical value increment modes. The system maintains interface simplicity by presenting a unified selection mechanism, while internally adapting to provide access to different sensitivity value ranges based on the selected method. This dynamic approach allows the system to expand its adaptability without complicating the user interface.

AI summary
An image capturing apparatus comprises an image capture unit, a setting unit configured to set a sensitivity serving as a setting for shooting using the image capture unit, and a selection unit configured to be able to select one of a first selection method capable of selecting a sensitivity from out of a plurality of sensitivities at a first numerical value increment, and a second selection method capable of selecting a sensitivity from out of a plurality of sensitivities at a second numerical value increment, as a method for selecting the sensitivity, the second numerical value being smaller than the first numerical value. Options selectable with the first selection method include a predetermined sensitivity that does not correspond to the first numerical value increment and is selectable with the second selection method.
