Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high frame rate is used for photographing, then photographing effect is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic frame rate adjustment by introducing a frame rate decision layer that adapts the frame rate based on real-time scene analysis. The system transitions from fixed frame rate to variable frame rate, selecting appropriate frame rates (e.g., 30fps, 60fps, or higher) according to scene complexity, motion detection results, and lighting conditions, thereby optimizing the balance between photographing quality and power consumption.
Solution Approach 2:
The patent changes the frame rate parameter dynamically based on scene characteristics. By analyzing scene complexity, motion detection data, and lighting conditions, the system adjusts the frame rate parameter to match actual photographing needs, avoiding unnecessary high frame rates in simple scenes and ensuring sufficient frame rates in complex scenes, thus resolving the contradiction between quality and power consumption.
2Device complexity
If frame rate control is coupled to hardware platform, then control is simplified, but function expansion and maintenance become difficult
Solution Approach 1:
The patent segments the frame rate control system into independent functional modules: a frame rate decision layer, scene analysis module, motion detection module, and hardware interface layer. This modular architecture allows the frame rate control logic to be separated from hardware-specific code, enabling independent optimization, testing, and updates of each module without affecting the entire system.
Solution Approach 2:
The patent introduces a frame rate decision layer as an intermediary between the hardware platform and the photographing functions. This intermediate layer provides a standardized interface that decouples the frame rate control logic from hardware dependencies, allowing different hardware platforms to be supported through configuration rather than code changes, thus facilitating function expansion and maintenance.
3Ease of operation
If fixed frame rate mode is used, then control is simple, but adaptability to different photographing environments is reduced
Solution Approach 1:
The patent implements self-service frame rate selection by enabling the system to automatically analyze scene characteristics and select appropriate frame rates without user intervention. The frame rate decision layer continuously monitors scene complexity, motion detection results, and lighting conditions, then autonomously adjusts the frame rate to optimize photographing quality for the current environment, maintaining ease of operation while improving adaptability.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors photographing scene characteristics and adjusts frame rate based on this feedback. The scene analysis module provides real-time information about scene complexity, motion detection results, and lighting conditions to the frame rate decision layer, which then adjusts the frame rate accordingly, creating a closed-loop control system that adapts to changing environments while maintaining simple operation.

AI summary
This application is applicable to the field of terminal technologies, and provides a photographing frame rate control method, an electronic device, a chip system, and a readable storage medium. In the photographing frame rate control method in this application, an electronic device may detect a first operation on a first control in a display interface; a frame rate strategy decision layer determines a target frame rate strategy based on initial data in response to the first operation; and the frame rate strategy decision layer generates a decision instruction based on the target frame rate strategy, where the decision instruction is used to control photographing frame rates of a plurality of cameras. In this application, the frame rate strategy decision layer is disposed at a hardware abstraction layer, to decouple configuration logic for controlling the photographing frame rates of the plurality of cameras from a hardware platform, so that subsequent function expansion and maintenance for control over the photographing frame rate are facilitated.
