Dynamic Image Playback Speed Control for Digital Browsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in quickly finding specific images among hundreds or thousands stored on digital image processing devices, as conventional image playback methods require excessive time and effort due to slow browsing speeds.
Innovation Solution
A digital image processing apparatus and method that adjusts the speed of switching between images based on the duration of a user's control signal, allowing for continuous or step-wise variation in switching speed, and optionally reduces image size and connects image edges for faster browsing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional image playback displays one image at a time with directional key navigation, then image quality and clarity are maintained, but the time required to browse through large numbers of images becomes excessively long
Solution Approach 1:
The patent implements dynamic adjustment of image switching speed based on the duration of control signal input. When users press the directional key briefly, images switch at normal speed. When users hold the key longer, the switching speed increases progressively, allowing rapid browsing through thousands of images while maintaining the ability to stop at any desired image by releasing the key.
Solution Approach 2:
The system changes the parameter of switching speed based on the duration parameter of control signal input. The detecting unit measures how long the user holds the directional key, and the playback image generating unit adjusts the switching speed accordingly, creating a direct relationship between input duration and browsing speed.
2Productivity
If multiple images are displayed simultaneously as thumbnails, then browsing speed improves, but the time to locate specific images and the complexity of the display interface increases
Solution Approach 1:
The patent maintains a simple single-image display interface but dynamically adjusts the switching speed between images. This dynamic speed adjustment provides the productivity benefits of fast browsing without the interface complexity of displaying multiple thumbnails simultaneously, keeping the display simple while improving browsing efficiency.
3Productivity
If image switching speed increases to reduce browsing time, then productivity improves, but the user's ability to accurately select specific images may be compromised
Solution Approach 1:
The system provides continuous feedback to the user through the duration-based speed adjustment mechanism. The user can feel the relationship between how long they hold the key and the resulting switching speed, allowing them to control the browsing process intuitively. Releasing the key immediately stops switching and displays the current image, providing precise selection control even at high switching speeds.

AI summary
Disclosed are an apparatus and method for improving digital image playback by switching among a plurality of displayed playback images according to a control signal generated from a user input. The apparatus includes a playback image generating unit (in an embodiment, a digital signal processor), which generates a playback image by using image data included in an image file. A display unit displays the playback image generated by the playback image processor. A detecting unit determines the duration of the control signal generated from the user input, and the playback image generating unit adjusts a specified speed of switching among a plurality of playback images according to the input of the control signal and the specified speed of switching playback images is adjusted according to the detected duration.
