Image Pickup Apparatus Transfer Protection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an image pickup apparatus that can manage the status of transferred images and prevent accidental deletion of images not yet transferred to an external device, particularly in scenarios where images are automatically transferred at predetermined timings, making it difficult for users to recognize transfer timings.
Innovation Solution
The apparatus includes a specifying unit for selecting images to be transferred, a transfer control unit for managing image transfers, a display control unit for displaying a screen to input deletion restrictions, and a restriction unit for associating deletion restrictions with specified images, ensuring that protected images are not accidentally deleted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If images are automatically transferred at predetermined timings, then transfer efficiency is improved, but user awareness of transfer status deteriorates
Solution Approach 1:
The patent implements a protection status display mechanism that provides continuous feedback to users about which images are protected from deletion. The display control unit shows protection icons or indicators on the image display screen, allowing users to understand the transfer status and protection state of each image without interrupting automatic transfer operations.
2Reliability
If deletion restriction is applied to transfer target images, then data integrity is improved, but operational flexibility deteriorates
Solution Approach 1:
The patent implements a dynamic protection mechanism where the protection status of images changes automatically based on transfer completion. Images are protected from deletion when designated as transfer targets, and this protection is automatically released after successful transfer. Users can also manually adjust protection status through designated operations, providing both automatic and manual control flexibility.
3Productivity
If automatic transfer function is enabled, then productivity is improved, but control over deletion timing deteriorates
Solution Approach 1:
The patent applies preliminary protection action by setting deletion restrictions on images before transfer occurs. When images are designated as transfer targets, they are automatically protected from deletion in advance, ensuring data integrity throughout the transfer process. This preliminary protection is then released after transfer completion, allowing flexible deletion management.

AI summary
An image pickup apparatus includes a specifying unit that specifies, as a transfer target, an image to be transferred to an external device from among images recorded in a recording medium, a transfer control unit that controls the specified image to be transferred to the external device, a display control unit that displays a predetermined screen for inputting an instruction for restricting deletion of the image specified as the transfer target, and a restriction unit that associates, in a case where the instruction for restricting the deletion of the image specified as the transfer target is input via the predetermined screen, information for restricting deletion with the image specified as the transfer target after inputting the instruction, and associates the information for restricting the deletion with images previously specified as the transfer target before inputting the instruction.
