Image Pickup Apparatus Parameter Recording for Color Grading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In digital cinema production, provisional color grading processing executed in image pickup apparatuses like digital cameras has limitations, leading to incomplete reduction of main color grading processing burdens, and external apparatuses are required for finer adjustments, making it difficult to maintain appropriate correspondence between processed images and grading parameters.
Innovation Solution
An image pickup apparatus with an image pickup unit, output unit, transmission unit, receiving unit, recording unit, and control unit that transmits and records parameter information with the external image processing apparatus, ensuring appropriate correspondence between the image and processing parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If provisional color grading processing is executed in the image pickup apparatus, then the burden of main color grading processing can be reduced, but only rough processing can be executed due to processing ability limitations
Solution Approach 1:
The color grading process is divided into two segments: provisional color grading executed in the image pickup apparatus and main color grading executed in the editing studio. This segmentation allows rough processing to be performed at the photographing site while reserving fine adjustment capabilities for the studio, thus resolving the contradiction between reducing processing burden and maintaining processing quality.
2Manufacturing precision
If external provisional color grading apparatus is used for finer processing, then processing quality can be improved, but it becomes difficult to maintain appropriate correspondence between processed images and grading parameters
Solution Approach 1:
The patent merges the functions of image pickup and provisional color grading into a single integrated apparatus. The image pickup apparatus includes both the image pickup unit and the color grading processing unit, allowing grading parameters to be directly associated with the captured images through unified control and storage mechanisms, thereby maintaining appropriate correspondence while enabling fine processing quality.
3Manufacturing precision
If external provisional color grading apparatus is used, then finer provisional color grading processing can be executed, but device complexity increases
Solution Approach 1:
The patent combines the image pickup apparatus and provisional color grading apparatus into an integrated system. The image pickup apparatus includes an image pickup unit, a color grading processing unit, and a control unit that coordinates both functions, eliminating the need for separate external equipment and reducing overall system complexity while maintaining fine processing capabilities.

AI summary
A control method of an image pickup apparatus has: an output step of outputting a photographed image to an external image processing apparatus; a transmission step of transmitting a transmission request of parameter information of an image processing to the photographed image which is generated by the external image processing apparatus, to the external image processing apparatus; a receiving step of receiving the parameter information from the external image processing apparatus; a recording step of recording the received parameter information in relation the photographed image; a detection step of detecting an operation in the image pickup apparatus; and a control step of executing a processing for transmitting the transmission request of the parameter information to the external image processing apparatus in the transmission step when the predetermined operation is detected in the detection step.
