Display Control Device Image Orientation Transformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems face challenges in automatically transforming images from an undesirable orientation to a desirable one without requiring user intervention, especially when connectors are positioned below the image display area, leading to inverted image displays and increased manufacturing complexity.
Innovation Solution
A highly optimized compression system utilizing specialized array instructions and a modified display-end buffer arrangement that reorders tile and pixel data based on display order information, allowing for efficient image transformation without additional processing power on the host side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If image data is input beneath the image display area to connect through the bottom of the display unit, then cable routing and manufacturing are simplified, but the image is displayed in an inverted orientation
Solution Approach 1:
The system performs preliminary detection of connector position and automatically applies the necessary image transformation (inversion or rotation) before display, so that the image is correctly oriented without requiring user intervention. This preliminary action resolves the contradiction by pre-correcting the orientation issue that would otherwise require user input.
Solution Approach 2:
The display device autonomously detects its own connector position and self-corrects the image orientation through automatic transformation. The system serves itself by eliminating the need for external user configuration, thereby resolving the contradiction between simplified manufacturing and proper image display orientation.
2Ease of operation
If software is provided at the host side to generate re-oriented display, then image orientation can be corrected, but user input is required which complicates operation for non-technical users
Solution Approach 1:
The display device automatically detects connector position and performs image transformation without requiring any user input or software configuration. This self-service approach eliminates the complexity of host-side software while maintaining proper image orientation, directly resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The image transformation function is extracted from the host computer software and implemented directly in the display device hardware. This extraction eliminates the need for complex host software and user configuration, simplifying operation while maintaining orientation correction capability.
3Ease of operation
If image transformation is performed before compression on the host side, then display orientation is corrected, but processing power and storage are consumed
Solution Approach 1:
The image transformation function is extracted from the host computer and implemented in the display device. This shifts the processing burden from the host to the display device, eliminating the need for transformation before compression on the host side and reducing host processing power consumption.
Solution Approach 2:
Instead of transforming the image data before compression on the host, the system transmits the data in its original orientation and performs the transformation after compression in the display device. This reverse approach maintains compression efficiency while achieving the desired orientation correction.

AI summary
A method, at a display control device, for transforming image data, the method comprising receiving portions of image data from a host device, wherein the portions of image data are based on tiles of an image, wherein the image comprises tiles in a tile order, each tile comprising pixels in a pixel order, and receiving display order information provided by host device, wherein the display order information provides an order for providing the portions of image data to a display device and generating different image data having a different tile order based on the display order information, and a different pixel order and providing the different image data the display device for displaying a transformed image.
