Playback Control Device for Sequential Still and Moving Picture Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing playback systems struggle to sequentially play back both still pictures and moving pictures in a user-desired order, often including unrelated moving pictures from servers, which disrupts the intended slide show experience.
Innovation Solution
A playback control device and method that selects moving pictures based on file name and format conditions, allowing for sequential playback of still and moving pictures in a predetermined order, with user-operated controls for navigating between previous, next, fast-forward, and rewind functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a folder is designated to store both taken still pictures and moving pictures along with unrelated moving pictures from servers, then all files in the folder can be played back, but unrelated moving pictures are also played back which disrupts the intended slide show experience
Solution Approach 1:
The patent extracts and separates relevant pictures (taken still pictures and associated moving pictures) from unrelated moving pictures in the folder. The playback control device identifies and plays back only the relevant pictures based on file name matching, effectively removing the harmful effect of unrelated content while maintaining the ability to play back multiple file types.
Solution Approach 2:
The system uses file name information as feedback to determine which moving pictures are related to taken still pictures. By checking whether moving picture file names match the taken picture file names, the system automatically identifies and excludes unrelated content from playback, resolving the contradiction between versatility and content relevance.
2Extent of automation
If an application program plays back all still pictures and moving pictures in a designated folder in predetermined order, then playback is automated, but the user cannot easily play back only desired still pictures and moving pictures
Solution Approach 1:
The playback control device performs self-service by automatically identifying relevant pictures through file name matching and organizing them for playback. This eliminates the need for manual selection while ensuring only desired pictures are played back, combining automation with user intent without requiring complex manual operations.
3Ease of operation
If the imaging apparatus plays back only still pictures for slide show display even when both still pictures and moving pictures are available, then simple slide show is maintained, but the function of playing back both still pictures and moving pictures sequentially is not realized
Solution Approach 1:
The patent merges the simplicity of traditional slide show playback with the enhanced capability to play back both still pictures and moving pictures. By automatically identifying and sequencing relevant pictures of both types based on file names, the system combines the ease of automatic playback with the versatility of mixed media support, resolving the contradiction between simplicity and adaptability.

AI summary
A playback control device includes a selection means for selecting a moving picture of a moving picture file having a file name satisfying prescribed conditions or a moving picture of a moving picture file having a prescribed file format and a still picture in still pictures and moving pictures, and a playback control means for controlling playback of the still pictures and the moving pictures so that still pictures and the moving pictures selected by the selection means are played back sequentially in the prescribed order.
