Imaging Device Bulb Exposure Preview Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During bulb exposure in imaging devices, photographers face challenges in determining the appropriate exposure time without previewing the image, leading to potential over or underexposure due to varying ambient conditions.
Innovation Solution
An imaging device with an image sensor, control section, adding processing section, and display section that repeatedly captures and displays image data at set intervals, allowing photographers to monitor exposure progress and adjust settings accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If bulb exposure is used for imaging subjects like starry skies or fireworks, then the exposure time can be extended to capture these scenes, but the photographer cannot determine the appropriate exposure time without risking over or underexposure
Solution Approach 1:
The patent implements a feedback mechanism by displaying a live preview image on a monitor during bulb exposure. The imaging section continuously captures images at predetermined intervals, and the display section shows these images to the photographer in real-time, enabling the photographer to monitor exposure progress and determine the optimal exposure time based on visual feedback rather than guesswork.
Solution Approach 2:
The patent performs preliminary actions by continuously capturing and displaying preview images during the exposure period before the final image is taken. This allows the photographer to assess exposure levels and make informed decisions about when to stop the exposure, preventing both overexposure and underexposure.
2Ease of operation
If images are captured and displayed at frequent intervals during exposure, then real-time monitoring of exposure progress is improved, but the power consumption and processing load increase
Solution Approach 1:
The patent implements periodic action by capturing and displaying images at predetermined intervals during bulb exposure rather than continuously. The control section is configured to perform imaging at specific time intervals, which reduces the frequency of image capture and display operations, thereby lowering power consumption and processing requirements while still providing adequate real-time feedback to the photographer.

AI summary
An imaging device comprising an imaging section for repeatedly forming subject images at a set period, while performing a bulb exposure operation, and outputting image data; an adding processing section for performing adding processing of the image data and previously output image data; an added image storage section for sequentially storing a plurality of added images that have been determined by the adding processing section; and a selection section for selecting any of the plurality of added images that have been stored in the added image storage section, after completion of the bulb exposure operation.
