Electronic Device Frame Mixing for Synchronized Image Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices generate composite frames by combining video and graphic frames without synchronizing image effect processing, leading to visual instability and poor image quality due to differing effects on each frame.
Innovation Solution
Perform image effect processing on both video and graphic frames before combining them to generate a composite frame, ensuring both frames undergo the same processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If image effect processing is performed only on the graphic frame before combining with the video frame, then the processing complexity is reduced, but the image quality and visual stability of the composite frame deteriorate
Solution Approach 1:
The patent merges the image effect processing operations for both video and graphic frames into a unified processing stage. The processor applies the same image effect processing to both frames simultaneously before they are combined by the mixer, ensuring consistent visual effects and eliminating the quality discrepancy that arises from separate processing.
Solution Approach 2:
The patent performs image effect processing on both video and graphic frames as a preliminary action before the frames are combined. This ensures that the visual effects are applied consistently to both frames in advance, preventing the need for post-processing adjustments and maintaining image quality throughout the composite frame generation process.
2Loss of time
If image effect processing is applied only to the graphic frame, then the processing time is reduced, but the visual stability of the composite frame deteriorates
Solution Approach 1:
The patent combines the processing timelines of video and graphic frames by applying image effect processing to both frames within the same processing cycle. This synchronization ensures that both frames undergo identical visual transformations at the same time, maintaining visual stability in the composite output.
Solution Approach 2:
The processor performs image effect processing on both frames as a preliminary action before the mixer combines them. This advance processing ensures that both frames are visually consistent before combination, preventing temporal mismatches that would compromise visual stability.
3Adaptability or versatility
If different image effect processing is applied to video and graphic frames, then the processing flexibility is increased, but the overall image quality of the composite frame deteriorates
Solution Approach 1:
The patent implements a universal image effect processing function that operates on both video and graphic frames using the same processing parameters and algorithms. This multi-functional approach maintains processing flexibility while ensuring consistent quality across different frame types by applying identical visual effects to both.
Solution Approach 2:
The patent applies homogeneous image effect processing to both video and graphic frames, using the same processing methods and parameters for both frame types. This homogeneity ensures that both frames maintain consistent visual characteristics when combined, preserving overall image quality while still allowing for different content types.

AI summary
An electronic apparatus may include: a video processor configured to output a video frame; a graphic processor configured to output a graphic frame; a mixer; and a processor which may be configured to: control the mixer to generate and output a first composite frame based on the video frame and the graphic frame, generate a second composite frame, which comprises a video area corresponding to the video frame and a graphic area corresponding to the graphic frame in a displayed image, and in which the video area and the graphic area have undergone image effect processing, based on an event of the image effect processing, and control the mixer to output the second composite frame.
