Camera Shake Prediction Using Historical Shutter Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses struggle to accurately predict and display camera shake values that occur during a shutter operation, as these values differ significantly from those measured during framing and are difficult to predict using existing methods.
Innovation Solution
An imaging apparatus equipped with a camera shake detection unit, shutter operating unit, image display unit, prediction range calculation unit, and camera shake display controller, which calculates and displays the prediction range of camera shake values based on the history of camera shake values after previous shutter operations, allowing for accurate prediction and display of camera shake loci and allowable ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If camera shake values in framing are used to predict camera shake values during shutter operation, then prediction can be performed, but the prediction accuracy is poor because the two types of camera shake values are quite different from each other
Solution Approach 1:
The system performs preliminary measurement of camera shake values during shutter operation and stores them as historical data. This preliminary action enables accurate prediction during actual shutter operations by comparing real-time framing camera shake values against the pre-collected historical distribution patterns, rather than using simple direct prediction methods.
Solution Approach 2:
The system establishes a feedback mechanism where camera shake values measured during shutter operations are continuously recorded and used to refine the prediction model. The prediction accuracy improves over time as the system accumulates more historical data and adjusts the prediction algorithm based on actual measured values, creating a closed-loop learning system.
2Loss of information
If camera shake values are displayed in real-time during framing, then users can confirm camera shake state, but users cannot anticipate camera shake values that will occur during shutter operation
Solution Approach 1:
The system pre-calculates and displays the prediction range of camera shake values that are expected to occur during shutter operation, based on historical data and current framing conditions. This allows users to anticipate future camera shake before actually taking the shot, enabling them to adjust their framing or stabilize the camera accordingly.
Solution Approach 2:
The system changes the display parameters from showing only current camera shake values to showing both current values and predicted future values with their respective ranges. This parameter change provides users with forward-looking information about expected camera shake during shutter operation, transforming the display from reactive to predictive.

AI summary
A camera shake detection unit detects a camera shake value. A shutter button that is a shutter operating unit is operated in imaging. A prediction range calculation unit calculates a prediction range of a camera shake value that occurs in a case where the shutter button is operated, on the basis of a history of the camera shake value after a previous operation of the shutter button. A camera shake display controller displays a locus of camera shake on an EVFLCD on the basis of the camera shake value detected by the camera shake detection unit before the operation of the shutter button, and displays the prediction range on the EVFLCD using a leading end of the locus as a starting point.
