Rear Camera Light Emitting Diodes for Selfie Timing Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties when taking selfies with rear surface cameras as they cannot identify the display in real time, making it hard to determine if the filming is being done correctly.
Innovation Solution
An electronic device with light emitting elements on its rear surface guides filming-related information by indicating the filming time point through a series of light patterns, allowing users to easily identify when to take the shot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rear surface camera is used for filming, then the camera can capture images from the rear view, but the user cannot identify the display in real time making it difficult to determine proper filming timing
Solution Approach 1:
The patent introduces light emitting elements as an intermediary device between the camera system and the user. These elements provide visual feedback (light signals) to indicate filming timing and status, enabling users to operate the rear camera effectively without needing to view the display in real time.
Solution Approach 2:
The system implements a feedback mechanism where the light emitting elements receive control signals from the processor and emit light patterns that correspond to the filming state. This closed-loop feedback allows users to understand the camera's operational status and timing without direct display observation.
2Loss of information
If the display is used for real-time viewing, then the user can identify what is being filmed, but the user cannot see the display when using the rear surface camera for selfies
Solution Approach 1:
The light emitting elements serve as an intermediary that conveys filming information to the user's hand or surrounding area, replacing the need for direct display viewing. This allows users to maintain awareness of filming status while holding the device for selfies.
Solution Approach 2:
The patent transitions the information display from a two-dimensional screen to a spatial light signal that can be perceived in three-dimensional space around the device. The light emitting elements are arranged to provide visual feedback in directions accessible to the user's hand during selfie filming.
3Ease of operation
If light emitting elements are added to the rear surface, then filming guidance is improved, but the device structure becomes more complex
Solution Approach 1:
The light emitting elements are integrated into the existing device architecture, serving multiple functions: indicating filming timing, providing operational feedback, and potentially serving as aesthetic design elements. This multi-functionality justifies the added structural complexity by delivering multiple benefits from a single component addition.
Solution Approach 2:
The patent combines the light emitting elements with the rear surface structure, integrating them into the housing or camera module assembly. This merging approach reduces the need for separate mounting structures and simplifies the overall implementation despite adding functional complexity.

AI summary
An electronic device according to an embodiment comprises: a front plate; a housing comprising a rear plate facing the front plate; a display exposed through at least one part of the front plate; a camera exposed through a first part of the rear plate; a plurality of first light-emitting diodes exposed through a second part of the rear plate near the first part; a processor operatively connected to the display, camera and plurality of first light-emitting diodes; and memory operatively connected to the processor. The memory, during execution, delays an imaging point by designated time and confirms whether or not a first function of imaging a still image has been configured if the processor receives a first input associated with imaging of the still image by means of the camera, and can store instructions, for guiding with respect to a degree in which the imaging point is reached, by means of the plurality of first light-emitting diodes if the first function has been configured.
