Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cinematography practices lack equipment for accurately recording and storing information on seasonal, weather, and lighting conditions during image capture, leading to inconsistent color correction results due to reliance on operator experience and trial-and-error methods, resulting in high costs and inefficiencies for video and movie production.
Innovation Solution
A standard color referencing panel system that captures and analyzes standard colors before image capture, using a memory, input unit, controller, and display unit to preheat and display scene and standard color content, allowing for accurate color correction in post-production by recording these conditions and applying them to images captured across different environments and camera models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual color correction is performed based on operator experience and trial-and-error methods, then color correction can be completed without specialized equipment, but the results are inconsistent and require significant time and cost
Solution Approach 1:
The system performs preliminary color calibration by capturing images of a standard color reference panel at the beginning of each shooting day and before scene changes. This preliminary action establishes baseline color data that eliminates the need for time-consuming trial-and-error corrections during post-production, directly resolving the contradiction between color accuracy and correction time.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring color temperature and reference panel images during shooting. This real-time feedback allows operators to make immediate adjustments to camera settings, preventing color drift and ensuring consistent color accuracy without requiring extensive post-correction time.
2Manufacturing precision
If manual color correction is performed without standardized equipment, then equipment cost is reduced, but manufacturing cost and inefficiency increase significantly
Solution Approach 1:
The system employs a universal standard color reference panel that can be used across different camera models, shooting locations, and lighting conditions. This single standardized tool provides multi-functional benefits by capturing both color temperature information and reference color data simultaneously, enabling consistent color reproduction across diverse production scenarios without requiring multiple specialized devices.
Solution Approach 2:
The standard color reference panel serves as an intermediary object between the lighting environment and the camera sensor. It mediates the translation of physical lighting conditions into standardized color data that can be processed algorithmically, bridging the gap between variable shooting conditions and consistent color output, thereby improving both precision and productivity.
3Reliability
If color correction relies on operator experience and imagination without objective data, then no specialized equipment is needed, but consistent results cannot be achieved across different operators and scenes
Solution Approach 1:
The system enables self-service color calibration by automatically capturing reference panel images and extracting color temperature and color data without requiring manual intervention or subjective operator judgment. The camera and processing software work together to autonomously establish color profiles, ensuring reliable and consistent results that are independent of operator experience or imagination.
Solution Approach 2:
The system creates objective digital copies of the shooting environment's color characteristics by capturing images of the standard reference panel under actual lighting conditions. These copied color data serve as reliable reference profiles that can be stored and reused, eliminating variability introduced by different operators and ensuring consistent color reproduction across multiple scenes and shooting days.
Data Source
AI summary
The present invention relates to a standard color referencing panel system for cinematography that reproduces the original colors of captured images. The standard color referencing panel system for cinematography includes a memory that stores scene display content and standard color display content of an object to be captured; an input unit that allows a user to turn on a power switch and an image capture start switch; a controller that supplies power in response to a power switch on a signal received from the input unit, transmits control signals in response to an image capture start switch on the signal received from the input unit, and reads the scene display content and the standard color display content from the memory; and a display unit that is supplied with power from the controller to preheat a screen, and displays the scene display content and the standard color display content on the screen in response to the control signals transmitted from the controller. According to the above-mentioned structure, it is possible to accurately and easily correct the colors of the captured image, and considerably reduce the time and cost required to correct the colors. As a result, it is possible to exactly reproduce the colors of the captured images and improve the quality of the images.
