Imaging Device Composition Assistance for Multiple Subjects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging devices lack the capability to provide composition guidance specific to scenarios with multiple persons, particularly when a man and a woman are photographed side by side, leading to unnatural image outcomes due to improper distance between subjects.
Innovation Solution
An imaging device equipped with an image pickup device, displaying device, person detection system, distance calculation functionality, and composition assistance features that display or notify subjects about the appropriateness of their distance, using visual or auditory cues to guide them into a proper composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional imaging devices are used without person detection and distance calculation, then the device complexity is low, but the composition assistance capability is insufficient for multiple persons
Solution Approach 1:
The imaging device is divided into distinct functional modules: image pickup device for capturing images, person detecting device for identifying individuals, distance calculating device for measuring spacing, and composition assisting device for providing guidance. This segmentation allows each component to perform its specific function efficiently while maintaining overall system adaptability for multiple-person composition assistance.
Solution Approach 2:
The imaging device integrates multiple functions into a single system: it can detect persons, calculate distances between them, determine whether the composition is appropriate, and provide assistance information. This multi-functionality enables the device to adapt to various shooting scenarios involving one or multiple persons without requiring separate devices.
2Loss of information
If person detection and distance calculation functions are added, then the composition assistance is improved, but the device complexity increases
Solution Approach 1:
The composition assisting device provides feedback information to the photographer based on the detected person positions and calculated distances. The system analyzes the current composition, determines whether it meets appropriate spacing criteria, and outputs assistance information guiding the photographer to achieve better composition, thereby reducing information loss about proper spacing.
Solution Approach 2:
The person detecting device and distance calculating device perform detection and calculation actions before the final image is captured. By preliminarily analyzing the scene composition and providing assistance information in advance, the system enables the photographer to adjust the composition before shooting, ensuring more accurate spacing without requiring post-processing corrections.
3Manufacturing precision
If the imaging device provides detailed composition assistance, then the image quality improves, but the ease of operation decreases
Solution Approach 1:
The imaging device automatically performs person detection, distance calculation, and composition evaluation without requiring manual intervention from the photographer. The system independently analyzes the scene, determines composition appropriateness, and provides assistance information, enabling the device to serve itself in optimizing composition while maintaining ease of operation.
Solution Approach 2:
The system changes the parameter of composition assistance based on the detected number of persons and their positions. When multiple persons are detected, the device activates specific composition criteria and provides targeted assistance information. This dynamic parameter adjustment ensures high composition quality while keeping the operation simple, as the system adapts its assistance level to the shooting scenario.

AI summary
An imaging device including an image pickup device which converts an optical image of a photographic subject received through an imaging lens into an image signal; a displaying device which displays a through-the-lens image based on the image signal; a person detecting device which detects one or more persons from the image signal; a distance calculating device which calculates a distance between a plurality of the detected persons; and a composition assisting device which displays on the displaying device information as to whether the distance between the detected persons is proper or not based on the calculated distance between the detected persons. Thereby, it is possible to obtain an image with a proper composition in a case when there are a plurality of persons being the photographic subjects.
