Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in capturing images or videos of the celestial pole, such as locating it within the field of view, due to its challenging identification in the sky.
Innovation Solution
An image capture device equipped with an electronic display, image sensor, optical element, rotational position sensor, location sensor, and north-direction sensor, which determines the celestial pole's location based on device position, direction, and field of view, and presents a graphical user interface to indicate its location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users attempt to locate the celestial pole manually in the sky, then they can capture images or videos of it, but the process becomes difficult and time-consuming due to the challenge of identification
Solution Approach 1:
The system provides real-time feedback by displaying a graphical user interface that shows the current field of view and indicates the location of the celestial pole. The electronic display continuously updates as the image capture device moves, giving users immediate feedback about whether the celestial pole is within the field of view and where it is located, thereby reducing the time and difficulty of manual location.
Solution Approach 2:
The patent introduces an intermediary system consisting of sensors (rotational position sensor, location sensor, north-direction sensor) and a processor that calculates and displays the celestial pole's location. This intermediary automatically determines the celestial pole's position based on device orientation and location data, eliminating the need for users to manually locate it in the sky.
2Ease of operation
If users manually identify and frame the celestial pole, then they can capture the desired visual content, but the operation becomes complex and difficult
Solution Approach 1:
The system performs self-service by automatically calculating and displaying the celestial pole's location within the field of view. The processor uses data from the rotational position sensor, location sensor, and north-direction sensor to determine where the celestial pole appears in the captured image, and the electronic display shows this information without requiring user intervention or complex manual procedures.
Solution Approach 2:
The patent replaces manual mechanical positioning and visual identification with an automated electronic system. Instead of users manually pointing the device and visually searching for the celestial pole, the system uses sensors to detect device orientation and location, processes this data to calculate the celestial pole's position, and displays it graphically, substituting mechanical manual operation with electronic automation.

AI summary
An image capture device may capture visual content with an optical element having a field of view. The location of the image capture device, the direction of north with respect to the image capture device, and rotation of the image capture device may be used to determine location of celestial pole with respect to the field of view. A graphical user interface may be presented on an electronic display. The graphical user interface may indicate the location of the celestial pole within the field of view.
