Imaging Apparatus Video Photo Mode Single File Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging apparatuses struggle to capture still images of transient events or subjects that change over time, such as accidents or moving objects, as they can only capture images at the moment the release button is pressed.
Innovation Solution
An imaging apparatus that shoots video and includes a video photo mode, allowing users to record video data during multiple shooting periods and generate a single file, enabling the extraction of high-quality still images from specific frames within the video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional imaging apparatus captures images only at the moment the release button is pressed, then the device complexity remains simple, but the user cannot capture transient events or subjects that change over time
Solution Approach 1:
The imaging apparatus is designed to perform multiple functions through a single device. It can operate in both still image shooting mode and video shooting mode, and can extract still images from recorded video data. This multi-functionality allows the device to capture transient events by recording video and then extracting specific frames, eliminating the need for separate capture mechanisms while maintaining operational simplicity.
Solution Approach 2:
The system performs preliminary video recording before the user needs to extract a specific still image. By recording video data continuously during the shooting period, the apparatus preserves the temporal information of events. The user can then review the recorded video and extract the desired still image at any convenient time, ensuring no transient moment is lost due to timing constraints.
2Productivity
If the imaging apparatus records video data during multiple shooting periods into separate files, then the file management is straightforward, but the user may miss photo opportunities due to time loss between recordings
Solution Approach 1:
The imaging apparatus merges multiple video data sets recorded during different shooting periods into a single video file. This consolidation eliminates the need for separate file management between recording sessions and ensures continuous availability of captured moments. The user can review and extract still images from the unified video file without interruption, preventing any loss of time between shooting periods.
3Measurement precision
If the imaging apparatus prioritizes video quality in video photo mode, then the video playback is smooth, but the extraction of high-quality still images from specific frames is compromised
Solution Approach 1:
The imaging apparatus applies different quality standards to different purposes: video data is recorded with sufficient quality for playback, but the still image extraction process applies enhanced processing to ensure high image quality. The system maintains local quality optimization by processing only the specific frames needed for still image extraction, rather than requiring the entire video to be recorded at maximum quality, thus balancing both requirements efficiently.

AI summary
The present disclosure provides an imaging apparatus that shoots a video. The imaging apparatus includes an imaging unit that generates image data based on optical information input through an optical system; an image processor that generates video data based on the image data; and a controller that, when a shooting period in which a video is shot has a first shooting period from a start of first recording till an end of the first recording and a second shooting period from a start of second recording till an end of the second recording, generates a single file using, out of the video data, first video data corresponding to the video shot during the first shooting period and second video data corresponding to the video shot during the second shooting period.
