Dynamic Sub Screen Positioning for Dual Camera Eye Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual camera systems, the difference in photographing directions between the front and rear cameras leads to unnatural images due to the user's eye direction not aligning with the camera view, causing the photographer's eyes to be looking at the main image from the rear camera instead of the front camera during dual shot mode.
Innovation Solution
The system adjusts the display of the sub screen image from the second image sensor to be physically closer to the second image sensor, allowing the user to align the photographing direction naturally by moving the sub screen display area closer to the second image sensor, and synthesizes the images during storage.

Engineering Contradiction Analysis
1Ease of operation
If the sub screen is fixed to a fixed location in the display unit, then the display layout is simple and stable, but the photographing direction does not align with the user's eye direction, causing unnatural images
Solution Approach 1:
The sub screen display location is changed from a fixed position to a dynamic position that moves according to the location of the second image sensor. This allows the sub screen to be positioned closer to the second image sensor, aligning the photographing direction with the user's eye direction and creating more natural images.
2Ease of operation
If the sub screen display area is moved closer to the second image sensor, then the photographing direction aligns with eye direction, but the display layout becomes more complex
Solution Approach 1:
The sub screen is positioned in a specific location closer to the second image sensor rather than using a fixed central position. This local positioning optimizes the photographing angle for natural images while maintaining overall system simplicity through location-based differentiation.

AI summary
An apparatus and a method for processing a plurality of images by using an electronic device are provided. The method includes displaying at least a portion of a first image obtained by a first image sensor functionally connected to the electronic device as a first preview image in a display functionally connected to the electronic device and displaying at least a portion of a second image obtained by a second image sensor functionally connected to the electronic device as a second preview image together with the first preview image in the display. An area of the display for displaying the second preview image corresponds at least to a location of the second image sensor in the display.
