Switch Operation Timing for Still Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing observation systems, users face difficulties in accurately capturing still images from a movie display, as they need to long press a switch while viewing the images, which can lead to incorrect timing for storing desired images as still images.
Innovation Solution
A control device that detects switch operations and determines whether a predetermined operation condition is met, allowing seamless switching between movie and still image display controls, enabling the storage of images as still images at the desired timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single switch is used to control multiple functions (movie display and still image storage), then device complexity is reduced, but ease of operation deteriorates because users may fail to capture images at the correct timing
Solution Approach 1:
The control device automatically captures a still image at the moment a switch operation is detected during movie display, before the user needs to manually intervene. This preliminary automatic capture action eliminates the timing accuracy problem while maintaining single-switch operation.
Solution Approach 2:
The system provides visual feedback by displaying the captured still image on the display device immediately after capture, confirming to the user that the image was successfully captured at the correct timing. This feedback mechanism resolves the ambiguity of whether the capture timing was accurate.
2Ease of operation
If automatic still image capture is implemented upon switch detection, then ease of operation is improved, but device complexity increases due to additional control logic
Solution Approach 1:
The existing single switch is made multi-functional by integrating both movie display control and still image capture trigger functions into one operation. This universal approach improves ease of operation while avoiding the need for separate dedicated buttons or complex multi-step control sequences.
Solution Approach 2:
The control device automatically performs the still image capture function itself when a switch operation is detected during movie playback, without requiring the user to navigate through menus or execute multiple commands. The system serves itself by autonomously capturing the image at the appropriate moment.

AI summary
A control device includes a processor configured to: perform movie display control of causing a display to sequentially display images acquired in time series, and still image display control of causing the display to display any of the images as a still image; detect a first operation on a switch; determine whether a predetermined operation condition for the switch is satisfied, after the first operation has been detected; switch, when the first operation is detected while the movie display control is being executed, from the movie display control to the still image display control and causing the display to display, as a still image, an image displayed at a timing at which the first operation is detected; and cause, when the processor determines that the predetermined operation condition is satisfied, a memory to store the image displayed as a still image under the still image display control.
