Image Playback System with Group Image Jump Forwarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems, particularly in digital cameras, face challenges in efficiently navigating and displaying large collections of images captured through burst mode or synthesis, where users struggle to find specific images due to limitations in image forwarding and jumping mechanisms, especially when group images are involved.
Innovation Solution
The system implements an image playback mode that allows for single-image forwarding and image jump forwarding based on attribute information, including group image flags and representative images, enabling efficient navigation through large image collections by displaying representative images of group images and allowing users to set custom jump numbers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If image jump forwarding is implemented with a fixed number of images, then navigation speed is improved, but group images may be skipped or displayed incorrectly when the number of images is less than the jump number
Solution Approach 1:
The patent makes the image forwarding mechanism dynamic by detecting whether the current image belongs to a group and adjusting the forwarding behavior accordingly. When a group image is detected, the system switches to representative image display mode; otherwise, it performs standard jump forwarding. This dynamic adaptation resolves the contradiction between navigation speed and display accuracy.
Solution Approach 2:
The system changes the forwarding parameter (number of images to skip) based on the detected image type. For group images, it uses a different forwarding strategy (displaying representative images) compared to regular images (jumping by fixed number). This parameter change allows the system to maintain both speed and accuracy across different scenarios.
2Ease of operation
If representative images of group images are displayed, then the number of operations to find desired images is reduced, but the system complexity increases due to group image detection and management
Solution Approach 1:
The system automatically detects whether the current image is a group image and switches to representative image display mode without requiring user intervention. The complexity of group image management is handled automatically by the system, maintaining ease of operation while managing the underlying complexity.
Solution Approach 2:
The patent introduces an intermediary mechanism (group image detection and representative image selection system) that automatically manages the complexity of group image handling. This intermediary layer shields the user from the complexity while providing simplified interaction through representative images.
3Productivity
If fixed number of images are skipped during forwarding, then navigation efficiency is improved, but many group images may be sequentially displayed when the number of group images is greater than the jump number
Solution Approach 1:
The patent extracts group images from the standard forwarding sequence and replaces them with representative images. This extraction prevents the sequential display of multiple group images during jump forwarding, maintaining navigation efficiency while reducing the quantity of images displayed.
Solution Approach 2:
The system skips over group images by displaying only their representative images during jump forwarding, rather than displaying each group image sequentially. This allows the forwarding operation to rush through large numbers of images efficiently while minimizing the actual display count.

AI summary
A display control device of the invention accepts a predetermined operation of switching an image to an image moved by a predetermined number of images among multiple images arranged in predetermined order. When a single-image that is not one of group images is displayed on a display unit of the display control device and single-images are arranged from the currently displayed image to an image moved by a predetermined number of images, the image moved by the predetermined number of images is acquired in accordance with a predetermined operation. When one of group images is displayed on the display unit and the group images are arranged within the predetermined number of images, a process of acquiring an image arranged beyond the group images without displaying images included in the group images is performed in accordance with a predetermined operation. Next, the acquired image is displayed on the display unit.
