Image Pickup Apparatus Shooting Direction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup apparatuses record moving image data regardless of changes in shooting direction, resulting in unwanted vibrating picture screens during reproduction.
Innovation Solution
An image pickup apparatus that detects the shooting direction and attitude using a three-axis geomagnetic sensor, temporarily stores moving image data, and deletes portions based on detected changes to record only desired data, preventing unintended image recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If moving image data is recorded regardless of shooting direction changes, then all captured data is preserved, but unwanted vibrating picture screens are recorded
Solution Approach 1:
The patent extracts and removes image data corresponding to periods with large shooting direction changes from the recorded moving image data. By identifying and extracting only the unwanted portions (those with significant direction changes), the system preserves desired data while eliminating unwanted vibrating picture screens.
Solution Approach 2:
The system uses shooting direction information as feedback to determine which image data to delete. By continuously monitoring shooting direction changes and using this information to selectively remove problematic frames, the system achieves intelligent filtering that maintains reproduction quality.
2Reliability
If all moving image data is recorded, then complete coverage is achieved, but recording medium is wasted
Solution Approach 1:
The patent extracts only the necessary portions of moving image data for recording by identifying and removing data corresponding to large shooting direction changes. This selective extraction approach reduces recording medium consumption while maintaining completeness of desired content.
Solution Approach 2:
The system changes the recording parameter by selectively deleting image data based on shooting direction change thresholds. By dynamically adjusting what gets recorded based on direction change parameters, the system optimizes recording medium usage without sacrificing important content.
3Reliability
If shooting direction detection is implemented, then unwanted images are prevented, but device complexity increases
Solution Approach 1:
The patent introduces shooting direction information as an intermediary element that mediates between the image pickup apparatus and the recording process. This intermediary data enables intelligent selection of which images to record without requiring complex real-time analysis of the actual image content.

AI summary
An image pickup apparatus includes an image pickup unit that picks up an object to generate moving image data. A detection unit detects one of a shooting direction of the image pickup unit and an attitude of the image pickup apparatus. A storage unit temporarily stores moving image data generated by the image pickup unit. An instruction unit instructs operation to photograph a still image. A recording unit reads out the moving image data traced back by a predetermined time period from a time point when still image photographing is instructed by the instruction unit, from the storage unit, and records the read-out moving image data in a recording medium. The recording unit records, relatedly with the moving image data, information concerning the detected one of the shooting direction and the attitude of the image pickup apparatus.
