Camera Focus Guide Visualization for Auto Focus Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices with camera functions lack a clear visualization of the auto focus detection process, making it difficult for users to understand and interact with the focus adjustment operation.
Innovation Solution
An electronic device with a camera module and a camera control module that obtains focus information, moves the lens to focus on a subject, and provides guide information through an output device, such as a display, to visualize the auto focus detection operation in real time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera automatically detects focus without user intervention, then the operation is simplified and faster, but the user cannot understand or control the focus adjustment process
Solution Approach 1:
The patent implements a feedback mechanism by displaying guide information on the screen that shows the lens movement status and focus detection progress in real-time. This allows users to see what the camera is doing during automatic focus detection, transforming an invisible process into visible feedback without requiring manual intervention.
Solution Approach 2:
The patent introduces guide information as an intermediary element between the automatic focus detection system and the user. This intermediary visualizes the lens movement and focus status, allowing users to understand the automated process without needing to manually control it.
2Productivity
If the lens moves quickly to achieve focus, then the productivity is improved, but the user cannot track or understand the movement process
Solution Approach 1:
The guide information provides continuous feedback during lens movement, showing the current focus status and lens position. This allows the system to move the lens quickly for productivity while simultaneously informing the user of the movement progress, eliminating the information loss.
Solution Approach 2:
The system performs preliminary actions by calculating and preparing the focus information before actual lens movement occurs, then displays this information in advance. This allows the lens to move quickly while the user is already informed of the intended and actual movement.

AI summary
An electronic device is provided. The electronic device includes a camera module, and a camera control module operatively connected to the camera module, wherein the camera control module obtains focus information of a subject to be captured by using the camera module, moves a lens of a camera to focus the camera on the subject based on at least the focus information, and provides guide information corresponding to the movement of the lens through an output device operatively connected to the electronic device.
