Solution Overview
Problem
Display apparatuses experience image delay issues when processing image signals, leading to desynchronization between user input and output, particularly in interactive applications like gaming, due to the processing of large data sets.
Innovation Solution
A display apparatus with an image signal processor that includes a user selector to choose from multiple image delay decrease modes, controlling components like the Y/C separator, de-interlacer, and image enhancer to minimize processing time, and an audio processor to synchronize audio signal processing with selected modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display apparatus processes a great deal of data internally to enhance image quality, then image quality is improved, but time delay is generated
Solution Approach 1:
The patent implements dynamic processing mode selection that adapts to different input sources and usage scenarios. The system can switch between full processing mode (for broadcast signals requiring de-interlacing and enhancement) and fast processing mode (for game signals requiring minimal delay), allowing optimal balance between image quality and processing speed based on real-time requirements
Solution Approach 2:
The patent changes processing parameters by selectively enabling or disabling specific processing functions based on the input source type. For game signals, the system modifies parameters by bypassing certain processing stages (de-interlacer, image enhancer) while maintaining others, effectively adjusting the processing pipeline to minimize delay while preserving necessary functionality
2Manufacturing precision
If the display apparatus uses advanced processing functions like 3D-comb, de-interlacer, and image enhancer, then image quality is enhanced, but processing delay increases
Solution Approach 1:
The patent segments the image processing pipeline into distinct functional modules (Y/C separator, video decoder, de-interlacer, scaler, image enhancer). This segmentation allows selective activation of individual modules based on the input source characteristics, enabling the system to apply only necessary processing functions and avoid unnecessary delays from redundant processing stages
Solution Approach 2:
The patent extracts and removes specific processing functions from the signal path when processing game signals. By taking out the de-interlacer and image enhancer from the processing chain for progressive scan inputs, the system eliminates unnecessary processing delays while maintaining adequate image quality for the specific application
3Manufacturing precision
If the display apparatus processes game signals with full image enhancement, then image quality is maintained, but input-output synchronization is lost
Solution Approach 1:
The patent implements dynamic processing mode selection that adapts to different input sources and usage scenarios. The system can switch between full processing mode (for broadcast signals requiring de-interlacing and enhancement) and fast processing mode (for game signals requiring minimal delay), allowing optimal balance between image quality and processing speed based on real-time requirements
Solution Approach 2:
The system uses feedback from the input source type detection to automatically adjust processing parameters. When a game signal is detected, the system receives feedback about the progressive scan format and automatically modifies the processing pipeline to minimize delay, ensuring input-output synchronization is maintained

AI summary
A display apparatus including an image receiver receiving an image signal and a display displaying the image signal. The display apparatus includes a user selector, an image signal processor to process at least one image delay decrease mode to decrease a processing time of the image signal and a controller to control the image signal processor to process the image signal according to the selected image delay decrease mode if an image delay decrease mode is selected through the user selector.
