Camera Guide Information for Self-Portrait Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of digital cameras face difficulties in capturing self-portraits without a tripod, as the photographer's perspective and background composition often differ from the user's intended setup, leading to suboptimal results.
Innovation Solution
A camera system that includes a photographing unit, display, user interface, and controller to extract and generate guide information by comparing the user's intended scene with the scene captured by another photographer, providing instructions to align the two and ensure the desired composition is achieved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user asks another person to take a photograph without a tripod, then the user can capture self-portraits without additional equipment, but the photographer's position and point of view differ from the user's intended composition
Solution Approach 1:
The camera provides real-time feedback to the photographer by displaying guide information that shows the difference between the currently captured scene and the user's intended scene. This feedback loop allows the photographer to adjust their position and composition based on visual cues until the desired result is achieved.
Solution Approach 2:
The camera acts as an intermediary between the user's intended composition and the photographer's actual capture. By extracting scene information from the user's reference photograph and comparing it with the current scene, the camera mediates the communication of compositional requirements to the photographer through guide information display.
2Manufacturing precision
If the camera extracts and compares scene information to generate guide information, then the composition accuracy improves, but the processing time and computational load increase
Solution Approach 1:
The camera performs preliminary extraction of scene information from the user's reference photograph before the actual photographing process. By pre-processing and storing key scene features, the camera reduces the computational burden during real-time comparison and guide information generation, thereby minimizing processing delays.
Solution Approach 2:
The camera extracts only the essential scene information needed for composition guidance from the user's reference photograph, rather than processing the entire image data. This selective extraction of relevant features reduces computational complexity and processing time while maintaining composition accuracy.

AI summary
A camera, and a method and apparatus for providing photographing guide information are provided. The camera extracts first scene information expressing features of a first scene that a user intends to photograph when a user input requesting scene setup is received. The camera extracts second scene information expressing features of a second scene that is captured in a photographing standby state. The camera uses the first scene information and the second scene information to generate guide information for guiding a photographer capturing the second scene to photograph the first scene, and providing the guide information to the display.
