Image Pickup Apparatus Automatic Time-Lapse Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup apparatuses require manual sorting of images with varying exposure levels to avoid unwanted brightness changes in time-lapse moving images, making the process cumbersome for users.
Innovation Solution
An image pickup apparatus with a control unit that automatically generates time-lapse moving images by composing photographed images acquired under multiple photographing conditions, including time-lapse and automatic bracket photographing functions, eliminating the need for manual sorting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If photographed images are used in photographed order to generate time-lapse moving image, then generation process is simple, but brightness changes repeatedly making the image uncomfortable
Solution Approach 1:
The photographed images are segmented by exposure level into multiple groups. The control unit separates images with different exposure conditions into distinct sets, then generates time-lapse moving images for each exposure level separately. This segmentation prevents mixing of bright and dark frames that would cause unwanted brightness fluctuations in the final moving image.
2Object-affected harmful factors
If images are sorted by exposure level to avoid brightness changes, then brightness stability is improved, but user operation becomes troublesome
Solution Approach 1:
The control unit automatically performs the sorting and grouping of photographed images by exposure level without requiring user intervention. The system self-services by identifying exposure conditions, categorizing images into appropriate groups, and generating separate time-lapse moving images for each group, thereby eliminating the need for manual sorting while maintaining brightness stability.
3Adaptability or versatility
If multiple photographed images are acquired under multiple photographing conditions, then image quality variety is improved, but processing complexity increases
Solution Approach 1:
The control unit segments the multiple photographed images into distinct groups based on their photographing conditions (exposure levels). By organizing images into separate groups according to their conditions, the system manages processing complexity through structured categorization while preserving the variety of image qualities captured under different conditions.
