Digital Camera Subject Tracking View Area Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital photographing apparatuses face difficulties in seamlessly synthesizing a face image with a background image, requiring cumbersome adjustments to achieve a desired composition.
Innovation Solution
A digital photographing apparatus and method that involves selecting a template image, detecting a subject, and dynamically adjusting a view area on the template image to match the subject's location, allowing for automatic synthesis of the subject with the background image, including blurring the boundary for a natural effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual movement of the photographing apparatus or background image is required to achieve desired composition, then composition flexibility is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically detects the subject's location and movement in real-time, and autonomously adjusts the view area position on the template image to track the subject. This self-service mechanism eliminates the need for manual camera movement or background image adjustment, allowing the system to adapt to subject position changes automatically while maintaining ease of operation.
Solution Approach 2:
The patent replaces the mechanical system of manually moving the camera or background image with an automated digital processing system. The controller detects subject position through image processing and programmatically adjusts the view area coordinates on the template image, substituting physical mechanical adjustment with software-based coordinate transformation and image synthesis.
2Ease of operation
If automatic subject detection and view area adjustment is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The controller performs multiple functions: it detects subjects in real-time images, tracks subject movement, determines view area positions on template images, and synthesizes final composite images. By integrating these diverse functions into a single controller unit that operates through standardized image processing and coordinate transformation algorithms, the system achieves automatic operation without proportionally increasing overall device complexity.
Solution Approach 2:
The system creates a digital representation (view area) of the subject's position and uses this copied positional information to adjust the template image display. Instead of complex direct manipulation, the controller copies subject coordinates from the real-time image and applies corresponding transformations to the template image view area, simplifying the control mechanism through coordinate mapping.

AI summary
A digital photographing apparatus, computer readable medium, and a method of controlling the digital photographing apparatus, the method including selecting a template image; receiving an image including a subject and detecting the subject from the received image; and displaying the template image with an image of the subject included in a view area. The displaying may include displaying the template image with an image of the subject included in a view area corresponding to a location of the detected subject. The method may include designating a location of the view area on the template image.
