Display Control for Anamorphic Image De-squeezing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anamorphic lenses cause distortion at the left and right ends of captured images, making it difficult to accurately represent objects when de-squeezing, and existing methods struggle to identify the image range limits for output targets with de-squeeze settings turned off.
Innovation Solution
An apparatus with a display control unit that displays anamorphic markers indicating the region of the image that will have a predetermined aspect ratio after de-squeezing, allowing users to easily recognize the valid region of an image format like CinemaScope, even when de-squeezing is not applied to all output targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If de-squeezing is applied to correct the distortion at left and right ends of the image, then the object representation accuracy is improved, but the image range is reduced due to cutting off side parts
Solution Approach 1:
The system performs preliminary de-squeeze processing on the captured image to correct distortion before outputting to multiple destinations. By pre-processing the image with the correct aspect ratio, the system ensures accurate object representation in the de-squeezed state while maintaining the ability to output both de-squeezed and non de-squeezed versions to different devices.
Solution Approach 2:
The system dynamically switches between de-squeezed and non de-squeezed output modes based on the capabilities and settings of different output devices. The display control unit can flexibly adjust the output format for each destination, allowing the same captured image to be optimally displayed on both anamorphic and non-anamorphic devices without loss of quality or accuracy.
2Adaptability or versatility
If de-squeeze setting is switched ON and OFF for different output targets, then the adaptability to different display devices is improved, but the difficulty in identifying image range limits increases
Solution Approach 1:
The system introduces an intermediary display control unit that manages the complexity of multiple output settings. This control unit acts as a mediator between the image processing unit and various output devices, automatically determining the appropriate de-squeeze setting for each destination and managing the image range limits without requiring manual intervention from the user.
Solution Approach 2:
The system provides visual feedback through markers displayed on the screen to indicate the valid image range for de-squeezed output. These markers help users understand which portions of the image will be properly displayed after de-squeezing, making it easier to compose and frame shots when working with multiple output targets with different de-squeeze settings.
3Measurement precision
If side parts are cut off to deal with distortion, then the object representation accuracy is improved, but the loss of image content increases
Solution Approach 1:
The system dynamically adjusts the output format based on the destination device capabilities. When outputting to devices that support anamorphic display, the full image including side parts is preserved and displayed with correct aspect ratio. When outputting to non-anamorphic devices, the system intelligently crops or scales the image to maintain quality, minimizing content loss while ensuring accurate representation.
