Composite Image Generation via Dual-Axis Object Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in capturing self-portraits with a good background ratio when using self-shooting mode, as they need to adjust the camera position and angle, often resulting in an image where the background is not recognizable due to limited arm length and difficulty in framing both the user and the background effectively.
Innovation Solution
A photographing device and method that separates the object from a captured image and superimposes it onto a live view of the background, allowing users to adjust the object's position, size, shape, color, and brightness on the background, enabling a composite image to be generated with improved background-object ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If self shooting mode is used to capture pictures of the user, then the user can photograph himself without assistance, but the picture is mostly filled with the user's face and the background is not recognizable
Solution Approach 1:
The patent introduces a second photographing unit positioned at a different spatial location (opposite direction) to capture the background, adding a dimensional perspective that the single self-shooting unit cannot provide. This allows simultaneous capture of both self-portrait and background from different viewpoints, resolving the contradiction between ease of self-shooting and background quality
2Adaptability or versatility
If the photographing device is placed on the ground or floor to use timer mode, then the shooting angle can be adjusted, but the device needs to be fixed to a certain position and the operation becomes complex
Solution Approach 1:
The system uses automatic object tracking and live view superimposition to guide the user, eliminating the need for manual positioning and fixing operations. The device automatically adjusts and maintains optimal shooting angles through real-time object detection and tracking, making the operation simple while maintaining versatility
3Ease of operation
If the user's arm length is limited in self shooting mode, then the user can hold the device easily, but it is difficult to frame both the subject and background effectively
Solution Approach 1:
The patent merges the images from two separate photographing units through composite image generation. The first unit captures the self-portrait while the second unit captures the background, and these are combined into a single cohesive image, achieving effective framing that neither unit could accomplish alone while maintaining ease of handheld operation

AI summary
A photographing device includes a photographing unit, an image processor which separates an object from a first photographing image obtained by the photographing unit, a display which displays a background live view obtained by superimposing the separated object on a live view of a background, and a controller which obtains a second photographing image corresponding to the live view of the background when a command to shoot the background is input and generates a composite image based on the separated object and the second photographing image.
