Rotation Processor for Image Width Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing devices face limitations in processing input images with widths exceeding their predetermined processing width, leading to restrictions on image size due to structural constraints, which can prevent the application of higher-resolution images.
Innovation Solution
Incorporating a rotation processor that generates temporary images by rotating the input images 90 degrees, allowing the image processor to handle images wider than its predetermined width by converting the width to a dimension within the processing limits, enabling image processing operations such as color adjustment, noise cancellation, and contrast adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image processor is designed with a fixed predetermined processing width, then the device structure remains simple and cost-effective, but it cannot process input images with widths larger than the predetermined width
Solution Approach 1:
The patent applies dimensionality change by rotating the input image 90 degrees, transforming the width dimension problem into a height dimension solution. The rotation processor converts a wide image (exceeding predetermined width) into a tall temporary image that fits within the processing width constraints, allowing the image processor to handle images of any aspect ratio without modifying its fundamental width limitation.
2Measurement precision
If image capturing technology is improved to increase resolution, then image quality is enhanced, but the image width may exceed the image processor's restriction
Solution Approach 1:
The rotation processor performs a preliminary action by rotating the high-resolution input image before it enters the image processor. This pre-processing step ensures that even high-resolution images with widths exceeding the processor's restrictions can be converted into a compatible format, allowing the image processor to maintain its fixed width design while supporting higher resolution inputs.
3Speed
If the image processor handles wider images directly, then processing speed is maintained, but the device cannot accommodate images exceeding its width restriction
Solution Approach 1:
The rotation processor acts as an intermediary component between the input image and the image processor. It transforms wide input images into temporary images with compatible dimensions, enabling the image processor to maintain its optimized processing speed for fixed-width images while accepting a broader range of input image widths through the mediation of the rotation step.

AI summary
An image processing device includes a rotation processor and an image processor. The rotation processor receives an input image and generates a temporary image according to the input image. The image processor is coupled to the rotation processor and outputs a processed image according to the temporary image, wherein the image processor has a predetermined image processing width, a width of the input image is larger than the predetermined image processing width, and a width of the temporary image is less than the predetermined image processing width.
