Image Format Conversion with Information Banner Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing methods for format conversion and information banner insertion often result in loss of visual information, deformation, or underutilization of screen space, especially when these operations are performed sequentially without considering the aspect ratio of the banner.
Innovation Solution
A method that determines a 'useful' aspect ratio for extracting an image part from a source image, taking into account the aspect ratio of both the final image and the information banner, and generates a final image by juxtaposing the extracted image part and the banner, ensuring the preservation of zones of perceptual interest and maintaining the aspect ratio without using black bands or cropping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If format conversion is performed by adding black bands (letterbox/pillarbox), then the image is not deformed and screen space is preserved, but the screen space is underutilized and information loss occurs
Solution Approach 1:
The patent merges the format conversion operation with the information banner insertion operation into a single integrated process. By combining these two previously separate operations, the black bands that would normally be added during format conversion are replaced with useful information banners, thereby eliminating wasted screen space while maintaining image integrity.
Solution Approach 2:
The patent converts the harmful effect of wasted screen space (black bands) into a beneficial use by filling that same space with information banners. The area that would otherwise be unused or contribute to information loss is transformed into a valuable information delivery channel.
2Area of stationary object
If format conversion is performed by cropping the source image, then the final image fills the screen, but useful content is lost
Solution Approach 1:
The patent performs preliminary calculation to determine the optimal extraction ratio before actually extracting the image portion. By calculating the useful extraction ratio in advance based on the banner dimensions and final image requirements, the system ensures that the most important content is preserved while leaving exactly the right amount of space for the banner, thus preventing information loss.
Solution Approach 2:
The patent dynamically adjusts the extraction ratio parameter based on the specific dimensions of the information banner and the desired final image format. By changing this parameter according to the banner's aspect ratio and size, the system optimizes the balance between preserving useful content and making space for the banner.
3Ease of operation
If information banner is inserted after format conversion, then the banner can be added to the final image, but information loss is accentuated
Solution Approach 1:
The patent merges the format conversion operation with the information banner insertion operation into a single integrated process. By combining these two previously separate operations, the system avoids the information loss that would result from sequential processing, as the banner space is reserved from the beginning during the extraction phase.
Solution Approach 2:
The patent performs the image extraction with the banner dimensions taken into account before the banner is actually inserted. This preliminary action of calculating the useful extraction ratio based on banner dimensions ensures that the banner will fit perfectly without requiring subsequent cropping or resizing that would cause information loss.
4Area of stationary object
If anamorphic distortion is applied to convert format, then the image fits the screen, but the image is deformed
Solution Approach 1:
The patent extracts only the necessary portion of the source image that maintains the correct aspect ratio for the final display, rather than applying distortion to the entire image. By taking out the relevant portion and combining it with the banner, the system achieves proper screen utilization without deforming the image content.

AI summary
The present invention relates to a method for image processing to generate, from a source image having a predefined width to height ratio, called initial ratio, and an information banner having predefined width to height ratio, called banner ratio, a final image having a width called final and a height called final and for which the width to height ratio, called final ratio, is different from the initial ratio, comprising the following steps:determine a ratio called useful according to the final ratio and the banner ratio,extract from the source image a part of the image having a width to height ratio equal to the useful ratio, andgenerate, from the part of the image extracted and the information banner, a final image comprising in juxtaposition an image representative of the extracted image part having a width to height ratio equal to the useful ratio and an image representative of the information banner having a width to height ratio equal to the banner ratio.
