Display Image Processor Mode Switching for Low Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses experience significant time delays due to multiple image processing operations, which hinder real-time user interactions, especially in gaming applications where immediate reflection of user inputs is necessary.
Innovation Solution
A display apparatus with a user input unit and an image processor that can switch between two modes: a first mode performing essential image processing operations like ADC and scaling, and a second mode that omits non-essential operations like IPC and picture quality enhancing, allowing users to select the mode for reduced processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple image processing operations (ADC, scaling, IPC, picture quality enhancing) are performed to improve image quality, then picture quality is improved, but processing time increases causing time delay
Solution Approach 1:
The image processor dynamically switches between different processing modes (first mode with full processing for high quality, second mode with reduced processing for low latency) based on real-time user input detection. This dynamic adaptation allows the system to optimize the balance between picture quality and processing time according to the current usage scenario.
Solution Approach 2:
The system changes the processing parameters by selecting different processing modes with different levels of processing operations. In the first mode, all processing operations are executed for maximum quality, while in the second mode, processing operations are reduced to minimize time delay, thus changing the processing parameters based on operational requirements.
2Manufacturing precision
If full image processing operations are performed to maintain high picture quality, then picture quality is maintained, but user input response time increases making real-time game control unresponsive
Solution Approach 1:
The system dynamically adjusts processing intensity based on real-time user input detection. When user input is detected (such as in gaming scenarios), the system switches to the second processing mode that reduces processing operations, thereby improving user input responsiveness while maintaining acceptable picture quality for interactive applications.
Solution Approach 2:
The system applies partial processing by executing only the necessary processing operations for the current scenario. In gaming mode, the system performs essential processing (ADC, scaling) while omitting non-essential operations (IPC, picture quality enhancing), thus achieving sufficient functionality with reduced processing time for responsive user interaction.
3Loss of time
If image processing operations are reduced to minimize time delay, then processing time is reduced improving real-time response, but picture quality deteriorates
Solution Approach 1:
The system dynamically selects processing modes based on the operational context. For real-time interactive applications like gaming where low latency is critical, the system switches to the second processing mode that reduces processing time. For standard viewing scenarios, the system uses the first processing mode to maintain high picture quality, thus dynamically balancing processing time and quality according to usage needs.
Solution Approach 2:
The system changes processing parameters by implementing different processing modes with different levels of processing operations. The first mode executes complete processing for high quality output, while the second mode executes reduced processing for fast response, allowing the system to change parameters based on the specific application requirements.

AI summary
A display apparatus comprises a user input unit; an image processor operating in one of a first image processing mode performing a first image processing operation and at least one second image processing operation on an input image signal, and a second image processing mode not performing at least one second image processing operation on the input image signal. A controller controls the image processor to operate in one of the first image processing mode and the second image processing mode, according to a manipulation of the user input unit. Accordingly, a display apparatus performs in an image processing mode in which an image processing time is reduced, according to a user's selection.
