Solution Overview

Problem

Current camera systems face difficulties in accurately and efficiently selecting a main subject for tracking, especially when the subject is moving or when the user's reaction time is slow, due to limitations in user interface design and camera system latency, leading to potential image shaking and tracking failures.

Innovation Solution

A display control device and method that processes image data to present candidate and main subject areas in distinct forms, using a 'degree of stable presence' metric to automatically determine the main subject, thereby enhancing user recognition and reducing manual selection stress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a user manually selects a main subject from multiple candidate areas on a touch panel screen, then the user can designate the desired subject, but the selection becomes difficult when the subject is moving, the screen resolution is low, or the user's reaction time is slow

Engineering Contradiction:
Improveease of subject selectionVSAvoidprecision of subject designation
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The camera system automatically determines the main subject by analyzing candidate areas and their stability over time, eliminating the need for manual user selection. The system serves itself by autonomously identifying and tracking the most stable subject in the scene based on computational analysis of multiple candidate regions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary analysis by evaluating the stability of candidate areas before final subject determination. By pre-processing candidate regions and calculating their stability metrics in advance, the system prepares potential main subjects before user interaction or final selection is needed.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the camera system provides real-time through-image display for subject selection, then the user can see the current scene, but image shaking occurs when the user manipulates the shutter button to select a subject

Engineering Contradiction:
Improvereal-time subject selectionVSAvoidstability of through-image display
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The system extracts and processes only the candidate area information needed for subject determination, separating this analysis from the full through-image display. By extracting specific region data independently, the system avoids the instability caused by full-screen manipulation while maintaining accurate subject identification.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If the camera uses a small touch panel for subject selection, then the device remains compact and portable, but it becomes difficult for users to accurately designate subjects on the small screen

Engineering Contradiction:
Improvedevice portabilityVSAvoidease of subject designation
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The camera system autonomously determines the main subject by analyzing stability metrics of candidate areas, eliminating the need for users to manually interact with the small touch panel. The system serves itself by automatically identifying subjects based on computational analysis rather than requiring precise manual input on a small screen.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If the camera system automatically determines the main subject, then manual selection stress is reduced, but the user may not recognize or understand the determination process

Engineering Contradiction:
Improvereduction of selection stressVSAvoidtransparency of determination process
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system provides feedback by displaying candidate areas and their stability information to the user during automatic determination. This feedback mechanism allows users to understand what subjects are being considered and why certain areas are selected as main subjects, maintaining transparency while preserving the benefits of automatic determination.

Inventive Principle:
Principle #23Feedback

AI summary

Provided is a display control device including circuitry that performs a display image data process that is an image data process for display on image data that is a target of a main subject determination process such that at least candidate presentation for a candidate image set as a candidate for a main subject in the main subject determination process based on candidate image information and main subject presentation based on main subject information of a determination result of the main subject determination process are performed in different display forms. The circuitry also outputs processed image data to be supplied to a display.
