Lightograph System Rapid Image Capture for Dynamic Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems are unable to capture multiple images with different lighting configurations in rapid succession without subject movement, limiting the creation of dynamic light effects that can convey mood or story in photographs.
Innovation Solution
A computer-implemented method and system that capture a series of images with varying lighting configurations using multiple lighting sources, while ensuring the subject remains static, and generate an executable file to reproduce these lighting effects, allowing for the creation of a 'lightograph' – an animated image or video showcasing light transition across a subject.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple images are captured with different lighting configurations, then lighting effects and mood expression are improved, but subject movement and alignment difficulty increase
Solution Approach 1:
The system performs preliminary actions by having the subject assume a static pose before capture begins, and by pre-positioning multiple lighting sources in predetermined configurations. The capture sequence is executed in rapid succession while the subject maintains this preliminary position, ensuring alignment across all captured images while allowing diverse lighting effects.
Solution Approach 2:
The system applies dynamics by rapidly changing lighting configurations between successive image captures while the subject remains static. Different lighting sources are activated in different sequences and patterns during the capture series, creating dynamic lighting effects without requiring subject movement. This dynamic lighting approach resolves the contradiction by allowing lighting variety without compromising alignment precision.
2Productivity
If images are captured in rapid succession, then productivity and capture speed are improved, but control over lighting transitions and image quality may deteriorate
Solution Approach 1:
The system implements periodic action by capturing images in a structured sequence where lighting sources are activated in predetermined patterns. Each image in the series follows a specific lighting configuration schedule, ensuring reliable control over lighting transitions. The periodic capture rhythm maintains both high productivity through rapid succession and reliability through systematic lighting control.
Solution Approach 2:
The system uses feedback mechanisms to monitor and adjust lighting configurations during the rapid capture sequence. The coordinated control system tracks the capture progress and ensures each image receives the intended lighting treatment, maintaining reliability even at high capture speeds. This feedback loop prevents lighting effect degradation despite the rapid succession of captures.
3Adaptability or versatility
If multiple lighting sources are used, then lighting effect versatility is improved, but system complexity and setup time increase
Solution Approach 1:
The lighting system is segmented into multiple independent lighting sources, each capable of being controlled individually. This segmentation allows the system to achieve lighting effect versatility by activating different combinations of lights in different sequences. The modular segmented structure manages complexity by making each lighting element independently controllable rather than requiring complex integrated control of a unified system.
Solution Approach 2:
The multiple lighting sources are designed with universal control capabilities, where each light can serve multiple functions depending on the capture sequence. The same set of lighting sources can create different lighting effects by varying activation patterns, intensities, and timing. This multi-functionality reduces overall system complexity compared to having dedicated lighting systems for each specific effect.
Data Source
AI summary
A system and method are provided for creating a moving light image for visualizing light transition across a subject (e.g., a lightograph), and include an image capture apparatus, various light effect elements (e.g., including strobes) arranged at different locations around a subject, and a processor. The processor, upon receiving a trigger command, directs the image capture apparatus to capture images in rapid succession, i.e., sufficiently rapid that the subject is substantially static for a duration of a specified sequence of images. Each of the images may have a different respective lighting configuration via selective implementation of at least one of the various light effect elements. The processor automatically generates and stores an executable file associated with the captured plurality of images, wherein execution of the file causes retrieval and time-based reproduction of one or more of the images and corresponding lighting effects in a substantially static image reference frame.
