Information Processing Apparatus Dynamic Image Backup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for digital cameras require users to wait until all image data is backed up before browsing, leading to long waiting times when users want to access specific images, especially with increasing data sizes due to higher pixel counts and movie capturing functions.
Innovation Solution
An information processing apparatus and method that allows for the simultaneous display of reduced image data while backing up full image data, with the ability to change the order of data acquisition based on user-defined display conditions, enabling immediate access to desired images during the backup process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If backup processing of all image data is completed before display, then data completeness is ensured, but user waiting time increases significantly
Solution Approach 1:
The system performs preliminary actions by obtaining and displaying reduced image data before the complete backup process finishes. The host apparatus retrieves thumbnail data in advance from the memory card, displays it while backup continues in the background, and later replaces it with full-resolution images as they become available. This allows users to immediately browse images without waiting for complete backup.
Solution Approach 2:
The patent segments the image data into two parts: reduced image data (thumbnails) and full-resolution image data. The thumbnail data is obtained and displayed first, while the complete backup process continues in the background. This segmentation allows the display function to operate independently without blocking, resolving the contradiction between immediate display and complete data transfer.
2Ease of manufacture
If backup processing is executed in predetermined order, then systematic data management is achieved, but flexibility in accessing specific images is reduced
Solution Approach 1:
The system dynamically adjusts the data acquisition order based on user needs. While maintaining a systematic backup process in the background, the host apparatus can flexibly retrieve and display specific reduced image data according to user requests. The display order is not fixed but adapts to user interactions, allowing non-sequential access to images during the backup process.
Solution Approach 2:
The system performs preliminary retrieval of reduced image data for multiple images before the user actually requests them. This preliminary action prepares data in advance, allowing the user to freely navigate and select images without waiting for sequential backup completion, thus enhancing access flexibility while maintaining systematic backup operations.

AI summary
An information processing apparatus includes a first obtaining unit, a second obtaining unit and a display control unit. The first obtaining unit obtains, from an electronic device connected to the information processing apparatus, image data stored in a memory medium connected to the electronic device. The second obtaining unit obtains in advance reduced image data corresponding to the image data before obtainment of the image data by the first obtaining unit. The display control unit updates reduced image data displayed on a display unit, obtained by the second obtaining unit, in accordance with a display condition designated by a user. When the display condition is changed while the first obtaining unit is executing obtainment of image data, the first obtaining unit changes an obtainment order of image data based on the changed display condition.
