Camera Image Compositing Shows Target Movement in One View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing methods for home security cameras provide limited information in alarm events, with screenshots offering only preset monitored target information at a moment and double-speed video clips being inefficient for comprehensive browsing.
Innovation Solution
An image generation method that pastes regions containing a preset monitored target from multiple images into a background image, ensuring non-overlapping placement to create a composite image showing the target's movement, allowing complete information browsing in a single view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a screenshot of the alarm event is provided to the user, then the user can quickly preview the alarm event, but the amount of information provided to the user is too small
Solution Approach 1:
The patent merges multiple monitored images containing the target at different times into a single composite image. This combines the quick preview advantage of screenshots with the comprehensive information of multiple frames, allowing users to see the target's movement trajectory and complete alarm event information in one view.
Solution Approach 2:
The patent transitions from displaying a single momentary screenshot to a multi-dimensional composite image that shows temporal information (different time points) and spatial information (target position and movement trajectory) simultaneously. This adds the dimension of time to the spatial display, providing complete alarm event information.
2Loss of information
If alarm video clips are played at double speed, then the user can learn the information of the whole event, but it still takes a lot of time
Solution Approach 1:
The patent extracts the target region from each monitored image and creates a composite image showing only the relevant information (target and movement trajectory). This extraction eliminates unnecessary background details and time-consuming video playback, allowing users to quickly review complete alarm event information through the condensed composite image.
Solution Approach 2:
The patent segments the alarm event into discrete monitored images containing the target, then reassembles them into a composite image that preserves the temporal sequence and movement trajectory. This segmentation allows the system to process and display only the essential information frames rather than the entire video stream.
3Loss of information
If multiple sub-images are pasted into the background image, then the user can see the target's movement, but overlapping images cause display confusion
Solution Approach 1:
The patent performs preliminary processing by determining the pasting range for each sub-image before actually pasting them into the composite image. This preliminary action calculates the appropriate positions and sizes to ensure non-overlapping placement, preventing display confusion while preserving complete target movement information.
Solution Approach 2:
The patent applies different processing to different regions of the composite image. Each sub-image is pasted with adjusted size and position based on its specific characteristics and the overall layout requirements. This local quality adjustment ensures optimal display of target movement information while avoiding overlapping and confusion.

AI summary
The present application provides an image generation method, a camera device and a computer-readable storage medium. The method including: acquiring a background image and monitored images, each of the monitored images containing a monitored target; obtaining a plurality of sub-images based on a region in each of the plurality of monitored images, the region comprising the monitored target being a portion of each of the monitored images; and generating an image by putting at least two of the sub-images in the background image in a chronological order. By implementing of the above-mentioned method, the monitored target information about an alarm event can be quickly and completely browsed for a user.
