Image Pickup Apparatus OSD Alignment During Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup apparatuses face issues with mismatch between rotated captured images and superimposed information, such as superimposed images or mask images, during camera movements in pan or tilt directions.
Innovation Solution
An image pickup apparatus that includes an image capturing unit, a superimposing unit, and a control unit, where the control unit rotates the captured image while keeping the position of second information relative to the subject unchanged, and adjusts the position of first information relative to the subject, ensuring that the superimposed information remains aligned with the subject during image rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the captured image is rotated to adapt to camera movement directions, then the adaptability of the image display is improved, but the positional alignment between superimposed information and the subject deteriorates
Solution Approach 1:
The patent segments superimposed information into two categories: first information (OSD images like timestamps and icons) that rotates with the captured image, and second information (mask images covering specific subjects) that maintains its position relative to the subject. This segmentation allows each type of information to be handled differently during rotation, resolving the contradiction between adaptability and alignment precision.
Solution Approach 2:
The patent implements dynamic position adjustment for different types of superimposed information based on rotation conditions. When rotation is detected, the system dynamically changes the behavior of first information to rotate while keeping second information fixed relative to subjects. This dynamic adaptation maintains both the adaptability to camera movement and the precision of subject coverage.

AI summary
An image pickup apparatus capable of communicating with an external apparatus includes an image capturing unit, a superimposing unit, and a control unit. The image capturing unit captures an image of a subject to generate a captured image. The superimposing unit superimposes first information and second information on the captured image supplied from the image capturing unit. The control unit rotates the captured image supplied from the image capturing unit in a state in which a position of the first information superimposed by the superimposing unit relative to a position of the subject is changed while a position of the second information superimposed by the superimposing unit relative to the position of the subject is kept unchanged.
