Always On Camera Mode Instant Capture Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in capturing desired scenes quickly due to the need to run a camera application and preview images, leading to missed moments as scenes pass rapidly.
Innovation Solution
A terminal and controlling method enabling an Always on Camera (AoC) mode that allows instant image capture without displaying a preview image, providing a shot button on the screen, and evaluating image quality for guide information and user interface handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera application is run and preview image is displayed, then the user can see what is being captured, but the user cannot capture the scene quickly enough as it passes rapidly
Solution Approach 1:
The camera application is launched and the camera module is activated in advance before the user actually needs to capture an image. The terminal maintains a photographable state with the camera ready to capture instantly when triggered, eliminating the delay of launching the application and displaying preview at the moment of capture need
Solution Approach 2:
The patent extracts the preview display function from the essential capture process. Instead of requiring preview display as a mandatory step before capture, the system separates these functions: the camera can be ready to capture instantly without showing preview, and preview can be shown optionally if the user needs to see what is being captured
2Speed
If the camera application is kept running to capture scenes quickly, then the capture speed improves, but the energy consumption increases
Solution Approach 1:
The camera module operates in different states dynamically: a photographable state where it is ready to capture instantly (higher energy consumption) and a standby state where it consumes less energy. The system transitions between these states based on user needs, allowing quick capture when required while saving energy when immediate capture is not needed
Solution Approach 2:
Instead of keeping the camera running continuously, the system uses periodic activation where the camera is prepared for capture only when needed (when the user intends to take a picture) and is put into standby mode otherwise. This periodic operation reduces overall energy consumption while maintaining the capability for quick capture when required
3Productivity
If the camera module is activated in advance to enable instant capture, then the capture responsiveness improves, but the power consumption increases
Solution Approach 1:
The camera module is activated in advance and maintained in a photographable state (not fully on but ready to capture) before the user actually needs to capture an image. This preliminary preparation allows instant capture responsiveness when triggered while avoiding the continuous power consumption of keeping the camera fully active
Solution Approach 2:
The system changes the operational parameters of the camera module, transitioning it between different states: standby mode (low power) and photographable state (ready to capture). By adjusting these operational parameters based on user needs, the system achieves fast capture responsiveness only when required while minimizing power consumption during normal operation
