Camera Shooting Direction Control with Rotation-Aware Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing devices face challenges in intuitively guiding users to adjust pan/tilt head operations when rotating the image capturing element to desired shooting directions, especially when transitioning between different aspect ratios.
Innovation Solution
A control apparatus that includes processors and memories to obtain user instructions and control drive units to align the shooting direction of the image capturing unit based on rotation angles, ensuring the direction matches the user's intended movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image capturing element is rotated about the optical axis to change aspect ratio, then the shooting direction can be adjusted to capture images in different orientations, but the user finds it difficult to intuitively recognize the required pan/tilt head operations
Solution Approach 1:
The control apparatus provides visual feedback by displaying the captured image with a superimposed arrow indicating the current shooting direction. This feedback mechanism allows users to intuitively understand the relationship between pan/tilt operations and the resulting shooting direction, even when the image capturing element is rotated. The arrow overlay serves as real-time guidance that adapts to the current rotation state.
Solution Approach 2:
The control apparatus introduces an intermediary representation (the arrow overlay on the displayed image) that mediates between the user's pan/tilt operations and the actual shooting direction. This intermediary visual indicator translates the abstract pan/tilt controls into concrete spatial direction understanding, bridging the gap caused by the rotation of the image capturing element.
2Adaptability or versatility
If pan drive and tilt drive are separately controlled for independent operation, then operational flexibility is improved, but the complexity of controlling the shooting direction increases
Solution Approach 1:
The control apparatus merges the pan drive and tilt drive controls into a unified control interface where users can operate either mode independently or combine them. The system integrates both control modes while maintaining their individual functionalities, allowing flexible operation without increasing perceived complexity through a cohesive user interface that handles both separate and combined operations.

AI summary
A control apparatus includes one or more memories storing instructions and one or more processors executing the instructions to obtain a movement direction instructed by a user with respect to an image captured to be displayed by an image capturing unit, obtain at least one of a rotation angle by a rotation of the image capturing unit or an image capturing element of the image capturing unit about an optical axis of an imaging optical system or a rotation angle by a rotation of the displayed image about a center of the image, and control a first drive unit that moves a shooting direction of the image capturing unit in a first direction and a second drive unit that moves the shooting direction of the image capturing unit in a second direction that is different from the first direction.
