Front Camera Service Segmentation for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling pop-up front cameras in mobile terminals often result in long response times and increased software risk due to the simultaneous processing of pop-up/retraction events and camera operations within a single service, leading to reduced user experience and system instability.
Innovation Solution
A method where the camera service and pop-up motor service are separated, allowing independent processing of camera operations and pop-up/retraction functions, reducing interference and ensuring timely event responses, with the camera service controlling camera operations and the pop-up motor service handling mechanical actions through a bottom-layer motor service and geomagnetic sensor feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pop-up motor service and camera service are integrated in a single service process, then the system structure is simpler, but the response time increases and system stability decreases
Solution Approach 1:
The patent divides the integrated service into two independent services: a pop-up motor service dedicated to controlling the mechanical pop-up/retraction of the front camera, and a camera service dedicated to camera operations. This segmentation allows each service to handle its specific tasks independently, reducing processing delays and improving response time while maintaining clear functional boundaries.
Solution Approach 2:
The patent extracts the pop-up motor control functionality from the camera service, creating a separate pop-up motor service. This extraction isolates the mechanical control operations from the camera operations, preventing interference between the two functions and enabling faster, dedicated response to pop-up events without being burdened by camera processing tasks.
2Device complexity
If the pop-up motor service and camera service are integrated in a single service process, then the system structure is simpler, but system stability decreases
Solution Approach 1:
By segmenting the service into independent pop-up motor service and camera service, the patent prevents error propagation between functions. If one service encounters an error, it does not affect the other service, thereby improving overall system stability while maintaining a manageable structure through clear service boundaries.
Solution Approach 2:
Extracting the pop-up motor control into a separate service isolates potential mechanical control errors from camera operations. This extraction ensures that instability in one service does not compromise the other, enhancing system reliability while keeping the overall architecture organized through service independence.
3Loss of time
If the pop-up motor service and camera service are separated, then the response time decreases and system stability increases, but the device complexity increases
Solution Approach 1:
The patent implements segmentation by creating distinct pop-up motor service and camera service processes, each with dedicated functionality. This segmentation improves response time by eliminating cross-functional processing delays and enhances stability through isolation, while the complexity is managed through well-defined service boundaries and standardized inter-service communication protocols.

AI summary
A method and device for controlling a front camera, and a mobile terminal are provided. The method for controlling the front camera includes: an operation instruction for the front camera is received from an application (S11); a trigger message is sent to a pop-up motor service to trigger the pop-up motor service to control a pop-up or retraction of the front camera (S12); and the front camera is controlled based on the operation instruction to perform a corresponding operation (S12).
