Light-field Camera Image Deletion Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When using a light-field camera, users may accidentally delete desired focused image data during deletion operations without proper confirmation, as existing techniques do not ensure that the focused image being displayed is the intended one for deletion.
Innovation Solution
An image processing apparatus that specifies the focus state of captured images, includes an operating unit for focus specification, an image generating unit for generating image data based on specified focus, and a display data generating unit for confirmation during deletion operations, ensuring the user can confirm the desired focused image before deletion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user performs deletion operation on image data captured by light-field camera, then the deletion operation can be executed, but the user may accidentally delete desired focused image data without confirmation
Solution Approach 1:
The system performs preliminary action by displaying the focused image data before the deletion operation is completed. The image display unit displays the image data corresponding to the specified focus state before the user finalizes the deletion, allowing the user to confirm whether the image to be deleted is the desired one.
Solution Approach 2:
The system implements feedback by displaying the focused image data back to the user during the deletion process. The image display unit provides visual feedback showing the image that will be deleted, enabling the user to verify the focus state and prevent accidental deletion of unwanted images.
2Adaptability or versatility
If the focus state is changed by the user before deletion, then the image data can be reprocessed, but the original focused image cannot be confirmed for deletion
Solution Approach 1:
The system creates a copy of the image data at the original focus state for display purposes. The image display unit displays image data that corresponds to the focus state specified by the user, allowing the user to review the focused image before deletion without affecting the ability to perform multiple focus state specifications.
Solution Approach 2:
The system displays the focused image data at the currently specified focus state before the deletion operation is finalized. This preliminary display action allows the user to confirm the focus state that will be deleted, even if the focus state has been changed multiple times during the session.
3Reliability
If the system displays focused image for deletion confirmation, then accidental deletion can be prevented, but the deletion process becomes more complex
Solution Approach 1:
The image display unit serves multiple functions: it displays images during normal viewing, displays focused images for deletion confirmation, and adapts its display content based on the operational context. This multi-functionality allows the system to provide deletion confirmation without requiring a separate dedicated display mechanism.
Solution Approach 2:
The system merges the deletion confirmation display function with the existing image display unit. Instead of creating a separate confirmation interface, the system utilizes the existing image display capabilities to show the focused image data, thereby integrating the confirmation process into the existing display framework.
Data Source
AI summary
An image processing apparatus generates an image data in which a focus state of a captured image is specified by calculation processing. An operation inputting unit is used for operating focus information for specifying the focus state of an image, and an image generating unit generates an image data by acquiring focus information. When image focus information is changed by specification made by a user, the image generating unit outputs the image data generated by using focus information prior to specification to a confirmation screen generating unit upon deletion operation of the image data. The confirmation screen generation unit generates a display data of a deletion confirmation screen for prompting a user to confirm deletion upon deletion operation of an image file. The display data of a deletion confirmation screen includes the image data generated by using focus information differing from the changed focus state.
