Solution Overview

Problem

There is a delay between the user's intention to capture an image and the actual capture time in existing digital photographing apparatuses, which hinders capturing images at the desired moment.

Innovation Solution

The apparatus includes a recognition unit to detect the user's movement approaching the image capture button, a capturing unit to capture multiple images, and a display unit to display a predetermined image, reducing the delay by determining the time difference between recognition and capture, and allowing for immediate image selection from captured frames.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If a user clicks a capture button to capture an image, then the image can be stored and displayed, but there is a delay time between the user's decision to capture and the actual capture moment

Engineering Contradiction:
Improvedelay timeVSAvoidcapture operation
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The system performs preliminary actions by continuously capturing images at a predetermined frame rate before the user actually clicks the capture button. When the button is clicked, the system selects an appropriate image from the pre-captured sequence, thereby eliminating the delay between user intention and image capture while maintaining simple operation.

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If multiple images are captured to reduce delay, then the desired image can be selected, but the device complexity increases

Engineering Contradiction:
Improvedelay timeVSAvoidcapture system
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system captures a sequence of images in advance at a predetermined frame rate, storing them temporarily in memory. When the capture button is clicked, the system selects an appropriate image from this pre-captured sequence based on timing information, thereby reducing delay without requiring complex real-time processing or additional hardware.

Inventive Principle:
Principle #10Preliminary action
