Digital Image Display Device with Variable Timing Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital media frames require manual configuration and user intervention for displaying new images, which is inconvenient and can lead to distractions, especially for elderly recipients who may not be tech-savvy, and there is a need for remote pre-configuration and variable image display durations.
Innovation Solution
A digital image display device with a processor, real-time clock, and image memory that allows for remote configuration and adjustable image display durations, enabling initial short display for new images and longer durations later to avoid distraction, using a system that includes a display screen, processor-accessible program memory, and user input interfaces for sequencing and modifying image display times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration and user intervention are required for displaying new images, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The system performs preliminary configuration actions by automatically detecting new images and setting appropriate display durations without requiring user intervention. The processor pre-determines the display strategy (short duration for new images, longer duration for subsequent images) based on automatic image analysis, thereby improving ease of operation while managing device complexity through automated logic.
Solution Approach 2:
The digital image display device serves itself by automatically detecting new images in the image memory and adjusting display durations without external user input. The system monitors its own state, identifies new content, and autonomously modifies its display behavior, eliminating the need for manual configuration and enhancing ease of operation.
2Loss of information
If fixed long display duration is used for all images, then user interaction is reduced, but loss of information increases due to distractions
Solution Approach 1:
The system dynamically adjusts the image display duration based on whether the image is new or previously displayed. The processor implements variable timing parameters: short display duration for new images to prevent distraction and allow quick glancing, and longer display duration for subsequent images. This dynamic adaptation resolves the contradiction by optimizing both information retention and user attention.
Solution Approach 2:
The system changes the time parameter of image display based on image novelty detection. The processor modifies the display duration parameter from a fixed value to a variable value that depends on the image state (new vs. old). This parameter change enables the system to minimize information loss by adapting display time to user viewing needs without requiring manual intervention.
3Ease of operation
If remote pre-configuration is implemented, then ease of operation improves, but device complexity increases
Solution Approach 1:
The system performs self-configuration by automatically detecting new images and adjusting display parameters without requiring remote setup or user intervention. The processor autonomously monitors the image memory, identifies new content, and modifies display durations accordingly. This self-service approach improves ease of operation while managing complexity through integrated automated logic rather than external configuration systems.

AI summary
A digital image display device for displaying a collection of digital images, comprising: a display screen; a processor; a real-time clock; an image memory for storing a plurality of digital images; and a processor-accessible program memory. The program memory stores executable instructions for causing the processor to execute the steps of: initiating a sequential display of a sequence of digital images on the display screen at an initial time, the sequence of digital images including at least a subset of the stored digital images, each digital image being displayed for an image display duration, the image display duration being set to an initial image display duration at the initial time; and modifying the image display duration during the display of the sequence of digital images.
