Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, the increasing number of visual output devices makes it difficult for users to reliably gather important information from multiple simultaneously presented images and video images, as existing systems struggle to effectively combine and transmit video data with transparency information.
Innovation Solution
An image processing system comprising a first unit, a second unit, and a video transmission link that transmits digital video data with a predefined data format, allowing for the transmission of uncompressed video images with an alpha channel in addition to three color channels, enabling the merging of video images to create a fused image with higher information content and reduced interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple visual output devices are used to provide increasing information to vehicle users, then information quantity is improved, but information gathering reliability deteriorates
Solution Approach 1:
The patent merges multiple video images with different transparency information into a single fused video image. The processing unit combines video images from multiple sources, applying transparency channels to determine pixel visibility and create a unified output that integrates information from multiple devices into one coherent visual presentation.
Solution Approach 2:
The video transmission link is designed with universal capability to transmit both standard three-channel video signals and four-channel video signals with transparency information. The system can handle multiple video image sources and process them through a unified transmission and processing pathway, allowing the same infrastructure to serve multiple information sources.
2Adaptability or versatility
If video images with transparency information are transmitted via a link designed for three color channels, then transmission compatibility is improved, but transmission completeness deteriorates
Solution Approach 1:
The patent adds a fourth dimension to the traditional three-channel video signal by incorporating an alpha channel for transparency information. Instead of merely expanding the color space, the system uses an additional temporal/dimensional layer (the transparency channel) that provides depth and layering information without interfering with the existing three-color-channel transmission protocol.
Solution Approach 2:
The system changes the parameter structure of video signals from three pixel values (RGB) to four pixel values (RGBA) per pixel. This parameter expansion allows transparency information to be encoded alongside color information, enabling the transmission link to carry both standard video data and transparency data using the same physical medium and protocol.
3Manufacturing precision
If uncompressed video images with four pixel values per pixel are transmitted, then image quality is improved, but data transmission complexity deteriorates
Solution Approach 1:
The patent segments the video data transmission into distinct components: three color channels (RGB) and one transparency channel (alpha). By separating the transparency information into its own dedicated channel, the system maintains the simplicity of the existing three-channel transmission infrastructure while adding transparency capability through a modular, add-on approach rather than redesigning the entire transmission system.
Data Source
AI summary
An image processing system for a vehicle includes a first unit, a second unit and a video transmission link, which couples the first and second units, in terms of signaling, for transmitting digital video data. The video transmission link transmits digital video image signals having a predefined data format for a respective pixel of a video image, the data format including three blocks, each having a predefined number of bits. The first unit ascertains an uncompressed transformed video image signal suitable for transmission via the video transmission link as a function of a respective first video image signal such that the transformed video image signal has the predefined data format of the video transmission link. The first video image signal represents respective uncompressed first video images of a sequence of first video images, which are provided at a predefined frame rate and which, in each case, have a first image resolution having a predefined number of pixels, wherein in each case four pixel values are assigned to the respective pixels of the first video image. The second unit is designed to again ascertain the first video image signal as a function of the transformed video image signal received via the transmission link.
