Solution Overview

Problem

Photographers face difficulties in setting subjects for balanced compositions, especially in short-time photography, as existing imaging devices require cumbersome operations to display auxiliary lines for composition guidance.

Innovation Solution

An imaging device with a control unit that recognizes subjects and displays specific guide marks at recommended positions on the screen, determining distances to adjust both the subject and background for balanced composition, facilitating easier photography.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a recommendation composition is decided and a photographer is notified, then the composition guidance is provided, but it is difficult to set a subject according to the composition and troublesome operations are required

Engineering Contradiction:

Improveease of subject positioningVSAvoidoperation complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The imaging device automatically recognizes subjects and calculates recommendation positions without requiring photographer intervention. The system serves itself by autonomously analyzing the image data, determining subject positions, and displaying guide marks, eliminating the need for manual composition adjustment operations

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical positioning operations with automated image processing and display systems. Instead of requiring photographers to manually adjust and position subjects based on complex operations, the system uses electronic image analysis and graphical display to guide subject positioning automatically

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If auxiliary lines are displayed for composition guidance, then balanced composition is achieved, but it requires detailed operations that are troublesome in short-time photography

Engineering Contradiction:

Improvephotography speedVSAvoidoperation simplicity

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system performs preliminary subject recognition and recommendation position calculation automatically before the photographer needs to make composition decisions. By pre-processing the image data and determining optimal subject positions in advance, the system eliminates the need for time-consuming manual adjustment operations during the photography process

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts only the essential information needed for composition guidance - specifically displaying guide marks at calculated recommendation positions - rather than requiring detailed manual operations. This extraction of key compositional elements simplifies the photographer's task while maintaining composition quality

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

There is provided an imaging device including a control unit that performs subject recognition. The control unit recognizes a first subject, decides a first subject recommendation position for the first subject in a screen from among a plurality of subject recommendation positions, displays a first specific display object at the decided first subject recommendation position, determines whether a distance between a position of the first subject and the first subject recommendation position is within a predetermined value, and decides a second subject recommendation position for a second subject in the screen from among the plurality of subject recommendation positions and displays a second specific display object at the second subject recommendation position when the distance is within the predetermined value.
