Intermittent Imaging Sensor Power Control and Video Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photographing apparatuses that perform intermittent imaging operations require manual access to multiple files for confirming images, making it inconvenient to review the captured still pictures.
Innovation Solution
A photographing apparatus equipped with an imaging sensor, power supply control unit, and moving-picture generating unit that continuously performs imaging operations in a predetermined interval, generating a moving-picture file from still pictures and adjusting playback speed by duplicating frames as needed, allowing easy confirmation of images through a moving-picture file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple still picture files are stored separately for intermittent photographing operations, then complete image data is preserved, but ease of operation deteriorates due to the need to manually access multiple files
Solution Approach 1:
The patent combines multiple still picture files obtained through intermittent photographing into a single moving picture file. The control unit integrates these separate image data files into one consolidated video file that can be played back sequentially, eliminating the need for users to manually access multiple individual files while preserving all captured image information.
Solution Approach 2:
The control unit acts as an intermediary that automatically processes and consolidates multiple still picture files into a single moving picture file. This intermediary function bridges the gap between separate image captures and user-friendly playback, automatically creating a unified video file that maintains chronological order and temporal relationships.
2Reliability
If the imaging sensor operates continuously to capture intermittent photographs, then image quality is maintained, but power consumption increases
Solution Approach 1:
The patent implements periodic imaging operations where the imaging sensor is activated only at specific intervals to capture still pictures, rather than operating continuously. The control unit manages periodic power supply to the imaging sensor, turning it on only when an image capture is needed and turning it off during intervals, thereby maintaining image quality consistency while significantly reducing overall power consumption.
Solution Approach 2:
The system discards continuous operation mode in favor of periodic activation. The imaging sensor is powered down during intervals between captures and only activated when needed, allowing the system to recover power for other functions during idle periods while maintaining the ability to capture high-quality images on demand.
3Reliability
If power is supplied continuously to the imaging sensor, then operational readiness is maintained, but heat buildup increases
Solution Approach 1:
The control unit implements periodic power supply to the imaging sensor, activating it only during required capture intervals and deactivating it during intervals between captures. This periodic operation maintains operational readiness when needed while allowing the sensor to cool down during inactive periods, thereby preventing excessive heat buildup.
Solution Approach 2:
The system takes preliminary anti-action by proactively powering down the imaging sensor during intervals between captures, preventing heat accumulation before it becomes problematic. This preventive approach maintains the sensor in a cooler state, extending its operational lifespan and preventing thermal issues that could arise from continuous operation.

AI summary
A photographing apparatus comprises an imaging sensor, a power supply controller, and a moving-picture generator. The imaging sensor continuously performs imaging operations in a predetermined interval. The power supply control unit controls power supply to the imaging sensor during a waiting period that is defined as a period from the end of one imaging operation of the imaging operations to the beginning of the next imaging operation of the imaging operations. The moving-picture generator generates a moving-picture file by incorporating a plurality of still pictures, obtained by the imaging operations, into a frame composing a moving picture.
