Virtual Capture Path Overlay for Consistent Cinematic Image Sequences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing graphical user interfaces for cameras do not facilitate the capturing of certain cinematic shots, as users often deviate from the intended path or move at inconsistent speeds, leading to suboptimal image capture.
Innovation Solution
A virtual indicator is overlaid on the physical environment to guide users along a predefined path for capturing cinematic shots, with features to adjust speed and compensate for deviations, using novel view synthesis to fill gaps in captured images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional camera interface is used, then the device complexity is low, but the image capture quality for cinematic shots deteriorates due to user deviation from intended path
Solution Approach 1:
A virtual indicator is introduced as an intermediary element between the camera interface and the user. This indicator overlays on the camera viewfinder to visually guide the user along the intended capture path, mediating the interaction and ensuring precise path adherence without requiring complex physical infrastructure
Solution Approach 2:
The system creates a visual representation (copy) of the intended capture path by overlaying a virtual indicator on the camera viewfinder. This graphical representation guides the user through the desired motion trajectory, transforming an abstract path requirement into a visible, followable guide that improves image capture quality
2Measurement precision
If users capture images manually without guidance, then the ease of operation is high, but the path adherence precision deteriorates
Solution Approach 1:
The virtual indicator provides real-time visual feedback to the user about their current position relative to the intended capture path. By displaying the desired path overlayed on the camera viewfinder, the system enables users to self-correct their positioning and maintain precise path adherence while keeping the operation simple and intuitive
3Manufacturing precision
If the camera moves at variable speed, then the adaptability is high, but the image capture consistency deteriorates
Solution Approach 1:
The system dynamically adjusts the camera's movement parameters by providing real-time visual guidance through the virtual indicator. The indicator adapts to the user's movement speed while maintaining guidance, allowing the camera to move at variable speeds without compromising image capture consistency. The path guidance remains effective regardless of the user's pacing

AI summary
Various implementations disclosed herein include devices, systems, and methods for displaying a visual indicator for capturing images. In some implementations, a device includes a display, an environmental sensor, a non-transitory memory, and one or more processors coupled with the display, the environmental sensor and the non-transitory memory. In various implementations, a method includes obtaining a request to capture a sequence of images depicting a subject. The sequence of images is to be captured while an image sensor is being moved along a path with a predefined shape. The method includes determining a dimension of the path. The method includes overlaying, on a pass-through of the physical environment, a virtual indicator that indicates the path with the dimension and the predefined shape. The virtual indicator guides a user of the device along the path while capturing the sequence of the images with the image sensor.
