Image Pickup Return Video Switching for Self-Shot Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup apparatuses display return videos regardless of necessity, potentially inhibiting the view of self-shot videos, especially in picture-in-picture mode.
Innovation Solution
An image pickup apparatus with a control unit that switches the display method of return videos based on a tally signal state, allowing the display to adapt to the need for visibility of self-shot videos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the return video is displayed on the display unit regardless of necessity, then the return video can be monitored, but the self-shot video display is inhibited
Solution Approach 1:
The patent applies dynamics by making the return video display state changeable based on tally signal conditions. The display unit dynamically switches between displaying return video and not displaying it, allowing the system to adapt to different operational scenarios. This resolves the contradiction by making the display area flexible rather than fixed, ensuring self-shot video display area is preserved when return video monitoring is not needed.
Solution Approach 2:
The patent changes the display parameter (visibility of return video) based on the tally signal state. When the tally signal indicates the camera is not selected, the return video is displayed; when selected, the return video display is inhibited. This parameter change resolves the contradiction by aligning return video visibility with actual operational needs, preventing unnecessary inhibition of self-shot video display.
2Adaptability or versatility
If the return video is displayed in picture-in-picture mode, then both videos can be viewed simultaneously, but the self-shot video visibility is reduced
Solution Approach 1:
The patent makes the picture-in-picture display dynamic by switching it on or off based on tally signal conditions. When the camera is selected (tally on), the picture-in-picture return video display is turned off, preserving full self-shot video visibility. When not selected, picture-in-picture mode enables dual viewing. This dynamic adjustment resolves the contradiction by providing dual viewing capability only when necessary.
Solution Approach 2:
The display mode parameter changes based on tally signal state. The system switches between full-screen self-shot video mode and picture-in-picture mode, adjusting the visible area parameters accordingly. This parameter change ensures that self-shot video visibility is maintained at maximum when return video monitoring is not required, while still providing dual viewing capability when needed.

AI summary
An image pickup apparatus that can switch a method for displaying a return video in accordance with the need to display the return video, thereby reducing the inhibition caused by displaying a return video when displaying a self-shot video. The image pickup apparatus connected to an external apparatus receives a tally signal and a return video, and switches a method for displaying the return video. The method for displaying the return video is switched depending on a state of the tally signal.
