Subtitle Data Overlay for Image Capture Time Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image playback systems, such as WINDOWS Media Player, do not display the capture time of images, making it difficult for users to determine when specific images were taken, especially in monitoring or security contexts.
Innovation Solution
A system and method that includes a storage device for capturing image data and environment conditions, creating subtitle data to display the image capture time, using a viewer like WINDOWS Media Player, which receives and plays back the image data along with subtitle data, including database and event data to provide the capture time as a subtitle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If general viewers (WINDOWS Media Player, REALPLAYER, QUICKTIME Player) are used to play back images, then ease of operation is improved, but the ability to display image capture time deteriorates
Solution Approach 1:
The patent introduces subtitle data as an intermediary element that carries timestamp information. The subtitle generation unit creates subtitle files containing capture time information, which is then displayed by the general viewer during image playback. This allows standard viewers to display timestamp information without requiring custom modifications to the viewer software itself.
2Loss of information
If subtitle data is created and displayed during image playback, then information completeness is improved, but device complexity increases
Solution Approach 1:
The system separates the timestamp display function into a distinct subtitle data component. Instead of integrating timestamp display directly into the image playback mechanism, the patent creates separate subtitle files that contain only the necessary time information. This segmentation allows the core image playback functionality to remain simple while adding timestamp capability through a separate, manageable data layer.
Data Source
AI summary
A system and method for displaying together images and an image capture time of captured images comprises a storage device and a viewer for displaying an image capture time. The storage device stores image data obtained from an image capture unit and environment data, which includes a storage medium, indicative of environment conditions where images are captured, and creates subtitle data based on the environment data to display a time of capturing the images as a subtitle. Also, The viewer receives the image data and subtitle data to play back the captured images based on the received data, and displays the image capture time using the subtitle data while the captured images are played back.
