Imaging Device Temporary Storage Ratio Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices lack an efficient method to manage and combine images captured before and after a crucial moment, limiting user flexibility in setting the duration and ratio of pre- and post-capture image storage.
Innovation Solution
An imaging device with a temporary storage system that detects a capturing instruction and records images for predetermined durations or numbers before and after the instruction, allowing users to set the total duration or number and ratio through an operational input unit, enabling flexible image combination and playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If images are cyclically stored for a fixed predetermined duration, then the storage system is simple and reliable, but the user cannot flexibly adjust the duration or ratio of pre- and post-capture images
Solution Approach 1:
The patent applies dynamics by making the storage duration and ratio adjustable rather than fixed. The record controller dynamically changes the first and second durations (or numbers of images) based on user-selected ratios, allowing the system to adapt to different recording needs while maintaining a manageable complexity through automated calculation.
Solution Approach 2:
The patent changes the parameters of storage duration and image count based on user input. By allowing users to select different ratios (e.g., 1:1, 2:1, 1:2) and automatically calculating the corresponding first and second durations or image numbers, the system achieves flexibility without requiring complex manual configuration.
2Adaptability or versatility
If the user can freely set both duration and ratio independently, then flexibility is maximized, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-defining several common ratio options (1:1, 2:1, 1:2, etc.). The user only needs to select from these predefined ratios rather than independently configuring both duration and ratio, which simplifies the operation while still providing flexibility for different recording scenarios.
Solution Approach 2:
The system automatically adjusts one parameter (duration or image count) when the user changes the ratio parameter. This automatic parameter adjustment maintains ease of operation by reducing the number of manual inputs required while achieving flexible configuration.
3Adaptability or versatility
If separate recording modes are provided for different duration ratios, then versatility is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by creating a single recording control system that can handle multiple duration ratios through parameter adjustment. Rather than implementing separate hardware or software modules for each ratio, the universal record controller adapts its behavior based on the selected ratio, reducing overall system complexity while maintaining versatility.

AI summary
An imaging device includes the following. A temporary storage cyclically stores images for a predetermined duration or number imaged in succession. A record controller records temporarily stored images for a first duration or a first number of images before detection of the capturing instruction, and records images for a second duration or a second number of images after detection of the capturing instruction. A setter preliminarily determines a total duration of the first duration and the second duration or a total number of the first number and the second number and determines a ratio of the first duration to the second duration or a ratio of the first number to the second number in response to one type of operation of an operational input unit, while retaining the preliminarily determined total duration or the preliminarily determined total number.
