Image-Capture Device Automatic Recording via Buffer and Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image-capture devices often miss capturing desired scenes due to late or failed operation, as operators must manually start recording while attending to both the device and the subject, leading to missed moments and inefficient resource usage.
Innovation Solution
An image-capture device equipped with an image-capture section, detector, evaluator, buffer section, and recording-operation controller that automatically records images based on predetermined conditions, allowing for delayed image storage and playback to capture desired scenes without operator intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation is used to start recording, then the operator can control when recording begins, but the operator often misses photographing due to late operation or failure to operate
Solution Approach 1:
The image-capture device automatically determines whether to start recording by itself based on evaluation values of captured images, without requiring operator judgment or manual operation. The device serves itself by autonomously deciding when the captured scene meets predetermined conditions for recording
Solution Approach 2:
The system accelerates the response time by using a buffer section that stores delayed images and rapidly evaluates them against predetermined conditions, enabling the device to quickly determine and execute recording start without waiting for manual operator response
2Reliability
If the operator presses the photography button earlier to prevent late operation, then missed photographing is prevented, but power and recording medium resources are wasted
Solution Approach 1:
The buffer section preliminarily stores delayed images in advance, so when a predetermined condition is met, the system can immediately start recording from the appropriate point in the buffer without needing to have recorded everything beforehand, thus avoiding waste of resources on unwanted scenes
Solution Approach 2:
The system continuously evaluates captured images against predetermined conditions and uses this feedback to determine exactly when to start recording, ensuring that recording begins only when necessary and not prematurely, thereby avoiding resource waste
3Ease of operation
If automatic recording starts when evaluation value exceeds threshold, then operator intervention is reduced, but events causing the situation and process of change are not recorded
Solution Approach 1:
The buffer section stores delayed images in advance before the recording start decision is made. When the evaluation value exceeds the threshold, the system retrieves and records images from the buffer that include the process leading up to the trigger condition, thus capturing the context and changes without requiring premature continuous recording
Solution Approach 2:
The buffer section acts as an intermediary between image capture and recording output, temporarily holding images and allowing the system to select and retrieve only the relevant portion (including the process leading to the trigger) for final recording, thus preserving context without continuous recording
4Ease of operation
If the operator pays attention to both the operation and the subject, then recording can be controlled, but the operator becomes distracted and late operation occurs
Solution Approach 1:
The image-capture device performs self-evaluation of captured images against predetermined conditions and autonomously determines when to start recording, completely eliminating the need for the operator to divide attention between monitoring the subject and operating the device
Solution Approach 2:
The system replaces the mechanical/manual operation of pressing a button by the operator with an automated electronic evaluation and control system that continuously monitors images and automatically triggers recording when conditions are met

AI summary
An image-capture device includes: an image-capture section that captures an image of a subject; a detector that detects a portion of the subject, the portion having a specific feature, from the image captured by the image-capture section; an evaluator that determines a numerically expressed evaluation value of the specific feature of the portion detected by the detector; a buffer section that temporarily stores delayed images corresponding to a predetermined amount of time; and a recording-operation controller that controls the image-capture device to record image data including a predetermined delayed image in the buffer section, upon determining that the evaluation value satisfies a predetermined condition.
