Duplex Thumbnail Mode for Image State Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing thumbnail mode in digital cameras displays small images, making it difficult to identify the state of activated images, leading to inconvenient and unnecessary operations during image search.
Innovation Solution
A duplex thumbnail mode is implemented, where a larger first thumbnail image is displayed alongside a second thumbnail image, created by reducing the first, without overlapping, allowing for easier identification of activated images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If thumbnail images are displayed in conventional mode, then multiple images can be displayed on a single screen, but the images are small and it is difficult to identify the state of activated images
Solution Approach 1:
The display is segmented into two distinct regions: a first region displaying conventional small thumbnail images and a second region displaying enlarged versions of activated thumbnail images. This segmentation allows users to see both the overview of multiple images and the detailed state of activated images simultaneously, resolving the contradiction between displaying multiple images and identifying image states.
Solution Approach 2:
The invention adds a spatial dimension to the display by creating a second region adjacent to the first region. Instead of simply enlarging images in the same space (which would reduce the number of visible thumbnails), the solution uses a two-dimensional layout with distinct display zones, allowing simultaneous presentation of multiple small thumbnails and one or more enlarged images.
2Difficulty of detecting and measuring
If activated thumbnail images are enlarged for identification, then image state can be clearly identified, but unnecessary operations are required to switch between viewing modes
Solution Approach 1:
The invention merges two viewing modes (thumbnail browsing mode and image enlargement mode) into a single unified display. Both the small thumbnail images and the enlarged activated images are displayed simultaneously in different regions, eliminating the need to switch between modes and allowing users to perform both browsing and identification operations in one view.
Solution Approach 2:
The system preliminarily prepares and displays enlarged versions of thumbnail images in the second region before the user needs to examine them in detail. This preliminary action of pre-loading and displaying enlarged images reduces the need for subsequent mode-switching operations, as users can directly observe image states without additional navigation steps.
3Area of stationary object
If only small thumbnail images are displayed, then screen space is efficiently utilized, but image quality and identifiability are insufficient
Solution Approach 1:
Different regions of the display are assigned different image qualities and sizes according to their specific functions. The first region displays small thumbnail images for efficient screen space utilization and overview browsing, while the second region displays enlarged high-quality images for detailed state identification. This local differentiation of quality resolves the contradiction between screen space efficiency and image identifiability.

AI summary
A method and apparatus for displaying images is provided. In particular, provided are a method and apparatus for displaying images using a duplex thumbnail mode in which images larger than thumbnail images are created when photographing images to display a larger image together with a corresponding activated thumbnail image whenever the thumbnail image is activated. The apparatus includes a signal processing unit that displays a first thumbnail image that is of the same size or larger than a second thumbnail image together with the second thumbnail image whenever the second thumbnail image is activated among displayed thumbnail images.
