Memory Card Gyro Sensor Insertion Direction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory cards with built-in gyro sensors face challenges in correcting blurring across various devices due to differing insertion directions, as the sensor information changes with device orientation, making it difficult to use a single memory card across different devices effectively.
Innovation Solution
A memory card equipped with a gyro sensor that detects angular velocities in three orthogonal axes, a determination unit to determine the insertion direction, and a recording unit to associate sensor outputs with the captured images, allowing for accurate blurring correction by allocating sensor data to specific axes (yaw, pitch, and roll) based on the insertion direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gyro sensor is built into a memory card for blurring correction, then blurring correction capability is improved, but the memory card cannot be universally used across different devices due to varying insertion directions
Solution Approach 1:
The determination unit determines the insertion direction of the memory card into the electronic device in advance, and the recording unit records this direction information together with the sensor outputs. This preliminary determination and recording of insertion direction enables the sensor data to be correctly interpreted regardless of how the memory card is inserted into different devices.
Solution Approach 2:
The insertion direction information acts as an intermediary that bridges the gap between the gyro sensor data and the actual device orientation. By recording and transmitting this intermediate information, the system can correctly map sensor outputs to the appropriate axes (yaw, pitch, roll) for blurring correction in any device configuration.
2Ease of manufacture
If sensor information is recorded without considering insertion direction, then recording simplicity is improved, but blurring correction accuracy deteriorates due to incorrect axis alignment
Solution Approach 1:
The determination unit determines the insertion direction in advance before blurring correction is performed, and this information is recorded alongside the sensor data. This preliminary determination ensures that when the data is later used for correction, the correct axis alignment can be applied without adding complexity to the recording process itself.

AI summary
The memory card includes: a gyro sensor that detects each of angular velocities in respective directions of axial rotation about three orthogonal axes; a first recording unit that records the moving image captured by the electronic device; a second recording unit that records each of first, second, and third sensor outputs indicating the angular velocities in the directions of axial rotation about the three orthogonal axes, which are detected by the gyro sensor, in association with the moving image to be recorded in the first recording unit; a determination unit that determines a direction of insertion of the memory card, which is mounted on the electronic device, into the electronic device; and a third recording unit that records information indicating the direction of insertion determined by the determination unit.
