Solution Overview
Problem
Existing distance measuring apparatuses with imaging capabilities suffer from image blur and vibration noise during moving image capturing due to built-in vibration devices, and lack integrated recording of still images or audio data.
Innovation Solution
A distance measuring apparatus with a vibrator controlled to avoid vibration during moving image capture, superimposing distance measurement information on the image to notify the user, and integrating still and moving image capture with distance measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vibrator is activated to provide operation sense feedback during distance measurement, then the user receives tactile notification, but image blur and vibration noise occur during moving image capturing
Solution Approach 1:
The system dynamically adjusts the vibration device operation based on the imaging mode. During moving image capturing, the vibration device is controlled not to operate, while during still image capturing or distance measurement only, the vibration device provides operation sense feedback. This dynamic control resolves the contradiction by adapting the vibration function to the current operational context.
Solution Approach 2:
The vibration feedback is selectively applied to different operational contexts. The system provides rich operation sense feedback for distance measurement and still image capturing, but suppresses vibration during moving image capturing. This localized application of vibration quality resolves the contradiction by tailoring the operation sense to the specific imaging mode.
2Adaptability or versatility
If the distance measuring apparatus integrates still image and moving image capture with distance measurement, then the functionality is enhanced, but the device complexity increases
Solution Approach 1:
The distance measuring apparatus is designed to perform multiple functions: distance measurement, still image capturing, and moving image capturing. The control device universally manages all these functions and determines the appropriate operation based on the current mode, enabling integrated recording without requiring separate dedicated systems for each function.
Solution Approach 2:
The patent combines the distance measurement function with the imaging functions into a single integrated system. The vibration device serves dual purposes: providing operation sense feedback for distance measurement and serving as a shutter mechanism for still image capturing. This merging reduces overall system complexity despite the enhanced versatility.
3Ease of operation
If the vibrator provides operation sense feedback during still image capturing, then the user receives tactile notification, but the vibration may be recorded by the built-in microphone
Solution Approach 1:
The vibration device operates periodically or in short bursts to provide operation sense feedback during still image capturing, rather than continuous vibration. This periodic action provides sufficient tactile notification to the user while minimizing the duration and intensity of vibration, thereby reducing the likelihood of vibration noise being significantly recorded by the built-in microphone.

AI summary
A distance measuring apparatus includes a distance measuring unit configured to measure a distance to an object, an imaging unit configured to capture still and moving images of the object, a display unit configured to display an object image obtained by the imaging unit, a vibrator configured to generate vibration in a case where the distance is measured by the distance measuring unit, and a processor configured to control the vibrator so as not to generate the vibration in a case where the distance measuring unit measures the distance during moving image capturing, and control the display unit to display an image in which information indicating that the distance has been measured by the distance measuring unit is superimposed on the object image.
