Self-Portrait Capture via Screen Gesture and Timer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal camera systems face instability and inconvenience during self-camera image capturing, particularly due to hand shaking and button placement issues for left- and right-handed users.
Innovation Solution
A method and apparatus for self-camera image capturing that uses a predetermined or user-configurable pattern on the screen for input, allowing users to perform image capturing without a dedicated button, by detecting specific user inputs to enter a half-shutter mode and complete the capture, enabling stable and convenient self-portrait photography.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user touches a button on the screen to perform image capturing, then the image capturing function is enabled, but the hand gripping the mobile terminal shakes or the hand's posture becomes unstable during self-camera image capturing
Solution Approach 1:
The patent introduces a self-camera mode as an intermediary solution that changes the interaction paradigm. Instead of directly touching the capture button with the thumb (which causes shaking), the user activates a timer-based automatic capture mechanism. The system then captures the image automatically after a predetermined time delay, eliminating the need for direct thumb contact on the button during the capture moment, thus resolving the hand stability issue while maintaining ease of operation.
2Productivity
If a user presses a key of the mobile terminal to perform camera image capturing, then the image capturing is triggered, but one of left-handed user and right-handed user has inconvenience due to fixed key position
Solution Approach 1:
The patent implements universality by making the self-camera mode accessible to all users regardless of hand preference. The timer-based automatic capture mechanism serves all users equally - whether left-handed or right-handed - by eliminating the need to press a physically located button. The functionality becomes universal as it relies on touchscreen interaction (tapping anywhere on the screen to start the timer) rather than a fixed physical key position, thus accommodating all users equally while maintaining rapid capture capability.
3Reliability
If a dedicated button is used for self-camera image capturing, then the capture function is reliable, but the device complexity increases and user convenience decreases
Solution Approach 1:
The patent applies self-service by enabling the camera system to automatically capture images without requiring a dedicated physical button. The timer-based mechanism allows the system to serve itself - once the user initiates the self-camera mode by tapping the screen, the system automatically waits for the predetermined time and then captures the image autonomously. This eliminates the need for additional hardware buttons or complex button configurations, maintaining reliability through automated operation while reducing device complexity.

AI summary
An apparatus capable of taking a self-portrait picture includes a screen, a camera, and a controller configured to cause the screen to display a live preview image received from the camera, after the live preview image is displayed, detect a first user gesture for triggering a display of an indicator on the screen, cause the screen to display the indicator at a changeable position where the first user gesture is detected, wherein the indicator indicates that a gesture detection mode is entered to recognize a second user gesture different from the first user gesture, while the indicator is displayed on the screen, detect the second user gesture in the indicator, and after detecting the second user gesture, cause the camera to automatically take a self-portrait picture.
