Image Frame Processing Separating Rendering from Display Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing variety of display devices with different frame rates and resolutions necessitates a more efficient image frame processing technology that can adapt to various rendering conditions without increasing manpower or processing load on the display device.
Innovation Solution
An image frame processing method that separates rendering and post-processing, allowing the generation of image frame sequences at a predetermined frame rate regardless of display specifications, with post-processing adapting the sequence to meet specific display conditions, such as resolution and frame rate, by integrating multiple image frames for fast-forwarding and motion blur effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image data are processed in the display device to adapt to various frame rates and resolutions, then the display can be adapted to different display specifications, but the processing load on the display device increases and more manpower is required for development
Solution Approach 1:
The patent extracts the image frame processing function from the display device and relocates it to a separate processing device. The display device only receives already-processed image data, eliminating the need for complex processing circuits and software within the display itself. This resolves the contradiction by maintaining adaptability through external processing while reducing the processing load and complexity of the display device.
Solution Approach 2:
The patent introduces an intermediary processing device that acts as a mediator between the image source and the display. This intermediary performs frame rate conversion, resolution adjustment, and other processing tasks, allowing the display device to remain simple while still achieving adaptation to various display specifications through the intermediary's processing capabilities.
2Adaptability or versatility
If more circuits and software are developed to support various frame rates and resolutions, then more display specifications can be supported, but the manpower required for development increases
Solution Approach 1:
The patent creates a universal processing device that can handle multiple frame rates and resolutions through a single set of processing circuits and software. Instead of developing separate processing solutions for each display specification, the universal processor adapts to different specifications through configurable parameters, significantly reducing development manpower while maintaining broad compatibility.
Solution Approach 2:
The patent utilizes parameter changes to achieve adaptability without increasing hardware complexity. The processing device adjusts operational parameters such as frame rate, resolution, and timing according to the target display specifications, allowing a single device design to support multiple display standards without requiring separate development efforts for each specification.
3Adaptability or versatility
If image frames are integrated for fast-forwarding, then value-added fast-forwarding pictures with motion blur effects are created, but additional processing steps are required
Solution Approach 1:
The patent performs preliminary integration of multiple image frames during the normal processing flow, preparing composite frames in advance that include motion blur effects. When fast-forwarding is requested, these pre-integrated frames are already available, eliminating the need for additional real-time processing steps and reducing device complexity while maintaining high picture quality.

AI summary
A rendering process for rendering an image frame and a postprocess for adapting the image frame to a display are separated. A rendering processing unit 42 generates an image frame sequence by performing rendering at a predetermined frame rate regardless of a condition that the image frame should meet for output to the display. A postprocessing unit 50 subjects the image frame sequence generated by the rendering processing unit to a merge process so as to generate and output an updated image frame sequence that meets the condition. Since the rendering process and the postprocess are separated, the image frame sequence can be generated regardless of the specification of the display such as resolution and frame rate of the display.
