Imaging Apparatus Eyepiece Sensor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face challenges in user-friendliness when switching between display devices, particularly due to false detections by the eyepiece sensor, which can incorrectly identify user interactions with the touch panel as the approach of the user's face, especially when the display devices are in specific orientations.
Innovation Solution
The implementation of a controller that dynamically sets the validity of the eyepiece sensor based on the orientations of the first and second display devices, ensuring the sensor is invalid when the first display device is not inclined and the second is, and valid when both are inclined, thereby reducing false detections and enhancing user-friendliness by automatic switching between display devices.

Engineering Contradiction Analysis
1Ease of operation
If the eyepiece sensor is always valid to enable automatic switching between display devices, then user-friendliness is improved, but false detection rate increases
Solution Approach 1:
The patent applies dynamics by making the eyepiece sensor's validity state changeable rather than fixed. The controller dynamically switches the eyepiece sensor between valid and invalid states based on the inclination states of the first and second display devices. This allows the system to adapt the sensor's operational state to the current configuration, reducing false detections when displays are in specific orientations while maintaining automatic switching capability when needed.
Solution Approach 2:
The patent changes the parameter of the eyepiece sensor's validity state based on the inclination parameters of the display devices. When the first display device is not inclined and the second is inclined, the sensor is set to invalid. When both are inclined, the sensor is set to valid. This parameter change approach allows the system to distinguish between different usage scenarios and adjust sensor behavior accordingly, balancing reliability and user-friendliness.
2Reliability
If the eyepiece sensor is set to invalid when the first display device is not inclined and the second is inclined, then false detection rate decreases, but automatic switching function may be limited
Solution Approach 1:
The system dynamically adjusts the eyepiece sensor's validity based on the real-time inclination states of the display devices. When both displays are in an inclined state suitable for eyepiece viewing, the sensor becomes valid and automatic switching is enabled. When the first display is not inclined, the sensor is invalidated to prevent false detections. This dynamic adaptation allows the system to maintain both reliability and versatility by activating the switching function only when the physical configuration supports it.
3Measurement precision
If the controller continuously monitors display device orientations to manage eyepiece sensor validity, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The system uses the display devices' own inclination states as the monitoring parameter. The first and second display devices provide information about their own orientations to the controller, which then determines the eyepiece sensor's validity. This self-service approach eliminates the need for separate, complex orientation sensing systems while maintaining accurate detection of the appropriate viewing configuration.

AI summary
The imaging apparatus includes a first display device, a second display device, an eyepiece sensor that detects that an object approaches the first display device, and a controller that switches the eyepiece sensor to be valid and invalid. The controller sets the eyepiece sensor to be invalid when the first display device is not inclined while the second display device is inclined. The controller sets the eyepiece sensor to be valid when the first and second display devices are inclined.
