Imaging Apparatus Adaptive Exposure Control for Time-Lapse Flicker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging technologies for time-lapse moving images struggle to adapt exposure conditions dynamically to changes in the imaging environment, leading to potential screen flicker and poor image quality when the environment changes during image capture.
Innovation Solution
An imaging apparatus and method that includes a specifying member to detect changes in the imaging environment, a setting member to determine whether to fix or adjust exposure conditions, and a control member to control imaging at regular intervals, ensuring continuous imaging with optimal exposure settings based on environmental changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If exposure conditions are fixed during time-lapse imaging, then screen flicker is prevented, but image quality deteriorates when imaging environment changes
Solution Approach 1:
The patent applies dynamics by making the exposure condition adjustment strategy adaptive rather than static. The system dynamically switches between fixing exposure conditions (when environment is stable) and adjusting exposure conditions (when environment changes), allowing the imaging system to respond flexibly to environmental variations while maintaining overall stability.
Solution Approach 2:
The patent changes the exposure parameters (shutter speed, aperture, ISO) based on detected environmental changes. When the imaging environment changes are detected by the specifying member, the control member adjusts these parameters to maintain optimal image quality, thus resolving the contradiction between stability and quality.
2Manufacturing precision
If exposure conditions are adjusted dynamically, then image quality is maintained during environmental changes, but screen flicker may occur
Solution Approach 1:
The patent implements feedback through the specifying member that continuously monitors imaging environment changes and provides information to the control member. This feedback mechanism allows the system to adjust exposure conditions only when necessary (when environmental changes are detected), preventing unnecessary adjustments that would cause flicker while maintaining image quality when needed.
Solution Approach 2:
The system dynamically determines whether to fix or adjust exposure conditions based on real-time environmental assessment. This dynamic decision-making process prevents unnecessary exposure changes (avoiding flicker) while enabling quality maintenance when environmental changes actually occur.
3Adaptability or versatility
If automatic exposure tracking is enabled, then adaptability to environmental changes is improved, but device complexity increases
Solution Approach 1:
The patent segments the exposure control function into distinct components: a specifying member that detects environmental changes and a control member that executes adjustments. This segmentation allows the system to implement adaptability through a modular architecture, reducing overall complexity by separating detection and control functions.
Solution Approach 2:
The system performs self-service by automatically detecting environmental changes and adjusting exposure conditions without requiring manual intervention. The specifying member and control member work together autonomously to maintain image quality, eliminating the need for complex manual control interfaces while preserving adaptability.

AI summary
An imaging apparatus includes: an imaging member; a specifying member to specify a change in an imaging environment when the imaging member performs imaging; a setting member to perform setting to determine whether an exposure condition is to be fixed or to be subjected to tracking, depending on the change in the imaging environment specified by the specifying member; and a control member to control the imaging member to image a still image according to a content set by the setting member, at a regular interval, during a predetermined time period.
