Image Capture Settings Control for Multi-Frame Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera systems dynamically modify camera settings for each image capture, leading to significant variations in settings across successive images, which can fail to meet the requirements of various multi-frame imaging applications.
Innovation Solution
A method and apparatus that determine and constrain specific image capture settings within predetermined ranges for successive images, allowing for controlled generation of images under distinct but consistent settings, enabling consistent image quality across subgroups of captured images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If camera settings are dynamically modified for each image capture, then the camera system can adapt to different imaging conditions, but the settings vary significantly across successive images, failing to meet requirements of various multi-frame imaging applications
Solution Approach 1:
The patent segments the image capture process into multiple subgroups, where each subgroup uses a fixed camera setting. This segmentation allows the system to maintain setting consistency within each subgroup while still providing adaptability across different subgroups for various multi-frame imaging applications.
Solution Approach 2:
The patent implements dynamic setting selection by determining different fixed settings for different subgroups of captured images. The system dynamically switches between different fixed settings based on the specific multi-frame imaging application requirements, rather than continuously varying settings for each image.
2Stability of the object's composition
If camera settings are fixed for each subgroup of captured images, then consistent image quality is achieved within subgroups, but multiple settings must be determined and managed
Solution Approach 1:
The patent determines the fixed camera settings for each subgroup in advance, before actual image capture begins. This preliminary determination simplifies the capture process by eliminating the need for continuous setting adjustments during image acquisition, reducing operational complexity.
Solution Approach 2:
The patent changes camera parameters (such as exposure time, gain, or other capture settings) to define different fixed settings for different subgroups. By systematically varying these parameters across subgroups, the system achieves both consistency within subgroups and adaptability across the full set of captured images.

AI summary
An image generation method includes: determining at least one first image capture setting and at least one second image capture setting; controlling an image capture device to generate a plurality of first successive captured images for a capture trigger event according to the at least one first image capture setting and generate a plurality of second successive captured images for the same capture trigger event according to the at least one second image capture setting. Variation of the at least one first image capture setting is constrained within a first predetermined range during generation of the first successive captured images. Difference between the at least one first image capture setting and the at least one second image capture setting is beyond the first predetermined range. Variation of the at least one second image capture setting is constrained within a second predetermined range during generation of the second successive captured images.
