Focus Lens Stopped at Positions for Video Capturing

Solution Overview

Problem

Existing imaging devices with focus bracket capturing functions face challenges in balancing image quality and recording time, as they either compromise on precision or duration when capturing multiple images at different focus positions.

Innovation Solution

The imaging device employs a dual video capturing method, where images can be captured with the focus lens stopped at each position for high precision and excellent image quality, or moved without stopping for reduced recording time, allowing users to prioritize between image quality and time based on the object's stability and depth of field.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the focus lens is stopped at each focus position during video capturing, then focus precision and image quality are improved, but recording time increases

Engineering Contradiction:

Improvefocus precisionVSAvoidrecording time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies dynamics by making the focus lens movable rather than fixed, allowing it to be positioned at different focus positions during video capturing. The lens can be stopped at specific focus positions for high precision capture or moved continuously for faster recording, providing dynamic adaptability between precision and speed requirements.

Inventive Principle:

Principle #15Dynamics

2Loss of time

If the focus lens is moved without stopping at each focus position, then recording time is shortened, but focus precision and image quality deteriorate

Engineering Contradiction:

Improverecording timeVSAvoidfocus precision

Core Design Contradiction:

AI summary

In the case in which a plurality of regions which is obtained by dividing an image region of the image data is set as partial regions, a controller detects focus positions respectively with respect to the partial regions and moves a focus lens to each of the detected focus positions to capture a video. The controller has, as a video capturing method for the video capturing, a first method in which the video capturing is performed with the focus lens stopped at each of the focus positions, and a second method in which the video capturing is performed with the focus lens being moved without stopped at each of the focus positions.
