Image Capturing Apparatus State-Based Object Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lifelogging cameras face challenges in capturing desired images when worn by users, as the camera's movement can result in objects being out of sight by the time a shot is taken, and unnecessary object searches consume battery power, reducing the duration of image capture.
Innovation Solution
An image capturing apparatus equipped with an object detection unit, state detection unit, and control unit that adjusts the object search range based on the camera's state, ensuring efficient object detection and reduced unnecessary searches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image capturing apparatus continuously searches for objects in all directions, then the probability of capturing desired images increases, but battery power is consumed and the duration of image capture is reduced
Solution Approach 1:
The patent applies dynamics by making the object search range adjustable based on camera movement state. When the camera is stationary, a wide search range is used to capture diverse objects. When the camera is moving, the search range is reduced or suspended to conserve battery power. This dynamic adjustment resolves the contradiction between capturing desired images and extending capture duration.
Solution Approach 2:
The patent changes the parameter of search range based on the detected state of the camera. By detecting whether the camera is stationary or moving and adjusting the search range parameter accordingly, the system optimizes both image capture quality and battery consumption, resolving the contradiction between reliability and duration.
2Reliability
If the image capturing apparatus performs object search operations frequently, then the quality of captured images improves, but battery power consumption increases
Solution Approach 1:
The system dynamically adjusts object search operations based on camera movement state. When stationary, frequent searches improve image quality. When moving, searches are reduced to save battery power. This dynamic control resolves the contradiction between image quality and power consumption.
Solution Approach 2:
The search frequency and range parameters are changed based on detected camera state. By adjusting these parameters according to whether the camera is stationary or moving, the system balances image quality requirements with battery conservation, resolving the energy consumption contradiction.
3Adaptability or versatility
If the camera searches for objects in a wide range, then the variety of captured images increases, but the time required for each search increases
Solution Approach 1:
The search range is dynamically adjusted based on camera state. When stationary, a wide search range captures diverse images. When moving, the search range is narrowed to reduce search time. This resolves the contradiction between image variety and search time efficiency.
Solution Approach 2:
The search range parameter is changed according to camera movement detection. By expanding the range when stationary and contracting it when moving, the system optimizes both the variety of captured images and the time efficiency of search operations.
