Gain Map Resizing Control for HDR Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies do not address the handling of gain maps when images with added gain maps are resized, leading to potential display issues on devices with incompatible dynamic ranges.
Innovation Solution
An image processing apparatus and method that generates conversion information for resizing images with different dynamic ranges, controlling whether to execute resizing processing on the gain map added to the image, including units for generating and resizing gain maps, and integrating or dividing regions to manage data efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If resizing processing is executed on an image with added gain map, then image size is changed, but the gain map may not be properly adjusted causing display issues
Solution Approach 1:
The control unit determines in advance whether to resize the gain map based on the resizing operation detected by the image resizing processing unit. This preliminary determination ensures that the gain map is properly adjusted before the actual display, preventing display compatibility issues while maintaining efficient processing.
Solution Approach 2:
The control unit receives feedback from the image resizing processing unit about the resizing operation and adjusts the gain map accordingly. This feedback mechanism ensures that the gain map remains consistent with the resized image dimensions, maintaining display compatibility.
2Reliability
If gain map is resized along with the image, then display compatibility is maintained, but processing time increases
Solution Approach 1:
The control unit dynamically adjusts the gain map resizing operation based on the detected resizing operation. When image resizing is detected, the control unit determines whether to resize the gain map accordingly, making the processing adaptive and efficient rather than always performing the same operations.
Solution Approach 2:
The control unit changes the processing parameters by determining whether to resize the gain map based on the image resizing operation. This parameter change allows the system to maintain display compatibility only when necessary, reducing unnecessary processing time.
3Productivity
If gain map is not resized, then processing is faster, but image quality and display compatibility deteriorate
Solution Approach 1:
The control unit determines in advance whether resizing the gain map is necessary based on the detected image resizing operation. This preliminary action allows the system to maintain image quality when needed while avoiding unnecessary processing that would reduce productivity.
Solution Approach 2:
The control unit changes the processing parameters dynamically, resizing the gain map only when the image resizing operation requires it. This parameter change maintains image quality and display compatibility while preserving processing speed for cases where resizing is not needed.
