Camera Remote Control Screen Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for remotely controlling image capture apparatuses lack the ability to selectively display different operation screens on external apparatuses, making it inconvenient for users to manage camera settings and status simultaneously with live view images.
Innovation Solution
An image capture apparatus and operation apparatus are designed with communication units, display units, and control units that allow for the generation and transmission of distinct operation screens, enabling selective display of OSD and GUI screens on external devices based on user instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the GUI of the out-of-finder display unit is displayed on the operation apparatus, then it is necessary to change the operation member of the GUI displayed on the operation apparatus to one corresponding to the out-of-finder display unit, but this increases operation complexity and reduces ease of operation
Solution Approach 1:
The patent segments the operation screens into two distinct types: OSD (On-Screen Display) and GUI (Graphical User Interface). The control unit selectively transmits either OSD or GUI to the external operation apparatus based on the display unit being used. This segmentation allows each screen type to be optimized for its corresponding display unit, reducing operation complexity when using the operation apparatus.
Solution Approach 2:
Instead of displaying the out-of-finder display unit's GUI on the operation apparatus (which would require changing operation members), the patent inverts the approach by displaying the viewfinder's OSD on the operation apparatus. This inversion maintains consistency between the display unit and operation members, improving ease of operation.
2Adaptability or versatility
If different operation screens are displayed on different display units of the camera, then users can perform operations while checking live view images or OSD, but it becomes necessary to manage multiple screen configurations which increases device complexity
Solution Approach 1:
The control unit provides universal functionality by selectively transmitting either OSD or GUI to the external operation apparatus based on which display unit is being used. This multi-functionality allows the same operation apparatus to work with both viewfinder and out-of-finder display units without requiring separate configuration systems, maintaining adaptability while reducing screen configuration complexity.
3Loss of information
If the operation apparatus displays the same screen as the out-of-finder display unit, then settings and status can be checked, but the operation members must correspond to the out-of-finder display unit which reduces ease of operation
Solution Approach 1:
The patent inverts the conventional approach by displaying the OSD (typically associated with viewfinder) on the operation apparatus instead of the GUI (associated with out-of-finder display unit). This inversion ensures that operation members on the external apparatus correspond to the viewfinder display, improving ease of operation while still providing full access to settings and status information through the OSD interface.

AI summary
An image capture apparatus which can be remotely controlled by an external apparatus. The image capture apparatus communicates with the external apparatus, generates a first operation screen which displays first information relating to the image capture apparatus and which includes a captured image, generates a second operation screen which is different from the first operation screen and displays second information relating to the image capture apparatus and does not include the captured image, and controls the image capture apparatus based on the operation request for the image capture apparatus received from the external apparatus. The image capture apparatus selectively transmits the first operation screen or the second operation screen to the external apparatus based on an instruction from the external apparatus.
