Imaging Device Intruding Object Detection and Preparatory Image Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices do not effectively utilize the information obtained during preparatory photography for main photography processing or replay purposes, and lack functionality to manage intruding objects within the photographic field.
Innovation Solution
The imaging device includes a main photography means, a preparatory image acquisition means, a photographic information acquisition means, and a recording means to correlate and record photographic information with images, allowing for the display of replay images that reflect the state of the photographic subject, including movement and setting changes, and features an intruding object detection system to control photography based on detected intrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If preparatory photography is performed to capture through images for composition checking, then the photographer can verify photo composition, but the information obtained during preparatory photography is not utilized for main photography processing or replay purposes
Solution Approach 1:
The patent performs preparatory photography to capture through images before main photography, and utilizes this preparatory information for multiple purposes including main photography processing (such as determining exposure settings, focus points, and composition) and replay display. This preliminary action prevents information loss by ensuring the preparatory data is actively used rather than discarded.
Solution Approach 2:
The preparatory images and their associated information are served multiple functions: they are used for composition checking during photography, for determining main photography parameters (exposure, focus, composition), for replay display to show the state during preparatory photography, and for detecting intruding objects. This multi-functionality maximizes the utility of the preparatory photography data.
2Loss of information
If the imaging device records and processes multiple types of photographic information from preparatory images, then comprehensive information is available for main photography and replay, but the device complexity increases
Solution Approach 1:
The patent segments the photographic information into distinct categories: image data, movement information, blinking state information, and intruding object information. Each segment is processed and stored separately, allowing the system to manage comprehensive information without overwhelming complexity. The segmentation enables targeted processing of each information type according to its specific requirements.
Solution Approach 2:
The patent introduces an intruding object detection mechanism that acts as an intermediary between the preparatory image acquisition and the main photography decision-making process. This intermediary analyzes the preparatory images to detect intruding objects and provides recommendations on whether to proceed with photography, thereby managing the complexity of information utilization.
3Reliability
If the imaging device detects intruding objects in the photographic field during preparatory photography, then unwanted photography can be prevented, but the detection and control mechanisms add device complexity
Solution Approach 1:
The patent implements a feedback mechanism where the intruding object detection result is fed back to control whether main photography should be executed. The system continuously monitors preparatory images for intruding objects, and based on the detection results, dynamically adjusts the photography execution decision. This feedback loop ensures reliable timing by preventing photography when intruding objects are present.
Solution Approach 2:
The imaging device performs self-service by automatically detecting intruding objects in the preparatory images and making its own decision on whether to proceed with main photography. The system uses its own captured preparatory images as the basis for intrusion detection, eliminating the need for external monitoring equipment and reducing overall system complexity.
4Loss of information
If replay display shows the state of photographic subject during preparatory photography, then realistic replay images are provided, but the processing and storage requirements increase
Solution Approach 1:
The patent extracts only the essential information from the preparatory images that is needed for realistic replay display: the state of the photographic subject (position, movement, blinking) and the background scene. Rather than storing and processing all preparatory image data, the system extracts and stores only the relevant attributes needed to recreate the photographic moment realistically, thereby reducing storage requirements while maintaining replay quality.

AI summary
An imaging device includes a main photography means for photographing a photographic subject and acquires a photographic image, a preparatory image acquisition means for performing preparatory photography before or after the main photography means acquires the photographic image and acquiring preparatory images, a photographic information acquisition means for acquiring photographic information related to a circumstance of photography when the preparatory images are acquired by the preparatory image acquisition means, and a recording means for recording the photographic information and the photographic image upon a recording medium in mutual correlation.
