Bluetooth Smart Watch Remote Photo Control via SPP
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of Bluetooth smart watches face inconvenience as they need assistance to take photos and cannot view them immediately after capture due to lack of remote control and immediate viewing capabilities.
Innovation Solution
A method and system utilizing the Serial Port Profile (SPP) protocol for Bluetooth smart watches to remotely control photo-taking on a smart terminal, where the watch sends instructions to the terminal to take photos, adjust and reduce the image resolution according to the watch's display size, and display the thumbnail on the smart watch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user wants to take a photo with a smart terminal camera, then the photo can be captured, but the user needs help from others and cannot view the photo immediately
Solution Approach 1:
The patent introduces a Bluetooth smart watch as an intermediary device between the user and the smart terminal camera. The watch receives photo-taking instructions from the user, transmits control signals to the terminal camera, and displays captured photos immediately on its own screen. This mediator eliminates the need for others to help take photos and enables immediate viewing without time delay.
Solution Approach 2:
The patent creates a functional copy of the photo viewing experience on the smart watch. Instead of requiring the user to view photos on the terminal device itself, the system captures photos and reproduces them on the watch's display, providing an immediate viewing experience that mirrors the original photo-taking action.
2Manufacturing precision
If the smart terminal camera takes a photo, then the photo is captured at full resolution, but the photo cannot be viewed immediately on the watch without assistance
Solution Approach 1:
The patent segments the photo handling process into two distinct stages: capturing at full resolution on the terminal camera and displaying at reduced resolution on the smart watch. The system maintains full resolution quality during capture but adapts the display resolution to match the watch's smaller screen, enabling immediate viewing without sacrificing the original photo quality.
Solution Approach 2:
The patent dynamically adjusts the photo resolution parameter based on the display device. When a photo is captured at full resolution, the system then transforms the resolution parameter to match the smart watch's display capabilities, allowing immediate viewing on the compact device while preserving the original high-quality capture.
3Manufacturing precision
If the Bluetooth smart watch displays photos at full resolution, then the image quality is maintained, but the watch display size is too small to show the full photo
Solution Approach 1:
The patent applies different quality standards to different parts of the photo viewing process. The terminal camera captures and stores photos at full resolution for quality, while the smart watch displays thumbnails at reduced resolution adapted to its smaller display area. This local quality adjustment optimizes the experience for each device's specific capabilities.
Solution Approach 2:
The patent uses partial action by displaying only a thumbnail portion of the full-resolution photo on the smart watch. Instead of attempting to display the complete photo at full resolution on the small screen, the system provides a condensed preview that is appropriate for the limited display area, maintaining sufficient image quality for immediate viewing.

AI summary
A method and system for remote control photography using a smart watch and smart terminal that communicate via a Serial Port Profile (SPP) protocol. The smart watch controls the smart terminal to capture a photograph that is then processed by the smart terminal to have a size and resolution compatible with a display of the smart watch.
