Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to capture natural actions of subjects in images when they move unexpectedly, as existing electronic devices struggle to adapt to the subject's motion.
Innovation Solution
An electronic device with a camera, display, and processor that estimates the motion of a subject within an image, controlling the camera to capture different types of images based on whether the motion is recognized or not, using predefined photographing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device captures images based only on user selection without motion recognition, then the operation is simple, but the ability to capture natural actions of moving subjects is poor
Solution Approach 1:
The system performs preliminary motion estimation by comparing current image frames with reference frames before final image capture. This preliminary analysis allows the device to predict subject motion and prepare appropriate capture parameters in advance, enabling natural action capture without requiring complex real-time processing during the actual capture moment.
Solution Approach 2:
The patent introduces an intermediate motion estimation module that acts as a mediator between the simple user selection interface and the complex camera control system. This intermediary layer processes motion information from image frames and translates it into controlled capture decisions, bridging the gap between simplicity and adaptability.
2Manufacturing precision
If the electronic device applies different photographing conditions based on recognized motion, then the image capture quality improves, but the processing time increases
Solution Approach 1:
The system applies partial motion analysis by focusing computational resources only on key regions of the image frame where subjects are located, rather than analyzing the entire frame. This selective approach maintains high image capture quality through motion-aware parameters while significantly reducing overall processing time by avoiding redundant analysis of static background areas.
Solution Approach 2:
The patent dynamically changes photographing parameters such as shutter speed, aperture, and focus based on the degree of motion detected. When motion is recognized, the system adjusts these parameters to optimize capture quality for moving subjects. The parameter adjustments are proportional to the detected motion intensity, allowing the system to maintain high quality only when necessary, thus reducing unnecessary processing overhead.
3Measurement precision
If the electronic device continuously monitors subject motion, then the capture accuracy improves, but the energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system implements periodic motion estimation at strategically chosen intervals between image captures. The motion analysis is performed on selected reference frames rather than every frame, reducing computational load and energy consumption while maintaining sufficient detection accuracy for capturing natural actions. The periodic monitoring rhythm is optimized to detect significant motion events without wasteful continuous processing.

AI summary
An electronic device is provided. The electronic device includes a camera, a display, a processor electrically coupled with the camera and the display, and a memory electrically coupled with the processor. The memory is configured to store instructions which, when executed, instruct the processor to, when a photographing request signal is received, estimate a motion of a subject within an image that is acquired by the camera, when the motion of the subject within the image acquired by the camera is not recognized, control the camera to capture a first type image by applying a first photographing condition, and when the motion of the subject within the image acquired by the camera is recognized, control the camera to capture a second type image by applying a second photographing condition.
