PTZ Camera Dual Video Output for Auto-Flip Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
PTZ cameras experience difficulty in maintaining the intended image capturing direction due to auto-flipping, where the video is rotated by 180°, causing confusion between the user's joystick operation and the actual image capturing range movement.
Innovation Solution
An image capturing apparatus that outputs both a first image and a second image, where the first image is captured as intended and the second image is rotated by 180°, allowing users to intuitively control the image capturing direction by displaying both videos with opposite arrow indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the image capturing apparatus rotates the captured video by 180° to correct the inverted image orientation, then the image orientation is corrected, but the control direction becomes opposite to the user's intention
Solution Approach 1:
The patent divides the video output into two separate video streams: a first video that is rotated by 180° to correct image orientation, and a second video that maintains the original orientation for intuitive control. This segmentation allows each video to serve a different purpose without interfering with the other.
Solution Approach 2:
The patent introduces an intermediary element (the second video with opposite arrow indicators) that mediates between the user's control intentions and the actual image capturing direction. The opposite arrow indicators serve as a visual mediator to reconcile the discrepancy between control input and image orientation.
2Shape
If the image capturing apparatus outputs only the corrected video, then the image orientation is correct, but the user cannot intuitively understand the actual image capturing direction
Solution Approach 1:
The patent segments the video information into two distinct streams with different orientations and indicator directions, allowing the user to choose which video to reference based on their needs.
Solution Approach 2:
The patent uses visual indicators (arrows) with opposite directions in the two video streams to convey different orientation information. The opposite arrow indicators provide visual cues that help the user understand the relationship between control direction and image capturing direction.
3Ease of operation
If the image capturing apparatus provides both videos with opposite arrow indicators, then the user can intuitively control the image capturing direction, but the device complexity increases
Solution Approach 1:
The patent implements video segmentation that divides the processed video into two oriented versions, each with appropriate arrow indicators. This segmentation approach manages complexity by organizing the processing into distinct, manageable stages.
Solution Approach 2:
The patent employs dynamic video processing that adapts the video orientation and indicator direction based on the image capturing direction. The system dynamically determines which video stream to output based on real-time capturing conditions.

AI summary
There is provided with an image capturing apparatus. An output unit outputs a first output image and a second output image based on an image capture result of the subject by the image capturing unit. The output unit, in a case where a predetermined condition including that an image capturing direction of the image capturing unit is within a predetermined range is satisfied, outputs a first image in which the image capturing unit has captured the subject as the first output image, and a second image in which the first image has been rotated as the second output image.
