Frame Rate Control Method for Image Processing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing apparatuses face instability in frame rate due to high system load and power consumption, leading to poor user experience, as conventional methods like thermal throttling fail to maintain a stable frame rate despite reduced system capacity.
Innovation Solution
A frame rate control method that dynamically adjusts the frame rate limit based on detected frame rate variations and system load, using a processor and frame rate controller to determine and implement the necessary limit, potentially incorporating temperature information for adaptive control.

Engineering Contradiction Analysis
1Use of energy by moving object
If thermal throttling is used to limit power, then power consumption is reduced, but frame rate stability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors frame rate stability and system load, then dynamically adjusts the frame rate limit accordingly. The controller detects frame rate variations and system load conditions, and provides appropriate frame rate limits to maintain stability while managing power consumption effectively.
Solution Approach 2:
The patent applies dynamic control by making the frame rate limit adjustable rather than fixed. The system dynamically changes the frame rate limit based on real-time detection of frame rate stability and system load conditions, allowing optimal balance between power consumption and frame rate stability under varying operating conditions.
2Productivity
If system capacity is increased to handle high game complexity, then processing capability is improved, but system load increases causing frame rate instability
Solution Approach 1:
The system uses feedback control by continuously detecting system load and frame rate stability, then adjusting the frame rate limit based on these detections. This allows the system to maintain high processing capability when conditions permit while preventing frame rate instability under high system load conditions.
Solution Approach 2:
The patent changes the frame rate limit parameter dynamically based on system conditions. By adjusting this parameter according to detected system load and frame rate stability, the system can optimize processing capability utilization while maintaining frame rate stability under varying workload conditions.
3Reliability
If frame rate limit is applied to stabilize frame rate, then frame rate stability is improved, but processing throughput is reduced
Solution Approach 1:
The patent makes the frame rate limit dynamic rather than static. The system adjusts the frame rate limit in real-time based on detected frame rate stability and system load conditions, allowing processing throughput to be maximized when stability is not an issue while providing stabilization only when and where needed.
Solution Approach 2:
The system changes the frame rate limit parameter adaptively based on operating conditions. By modifying this parameter only when frame rate stability issues are detected and adjusting it according to system load, the system maintains processing throughput efficiency while providing frame rate stabilization when necessary.

AI summary
A frame rate control method is provided. The frame rate control method includes the following step: detecting a frame rate of an image signal generated by an image processing apparatus to generate a first detection result; detecting a system load on the image processing apparatus to generate a second detection result; and determining whether to provide a frame rate limit to limit the frame rate according to at least the first detection result and the second detection result.
