Handshake Correction Module for Continuous Panorama Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in capturing continuous images during panorama shooting with digital cameras, as they struggle to align subsequent images accurately within a threshold value, leading to the need for reshooting.
Innovation Solution
A digital photographing apparatus equipped with a handshake correction module, which adjusts the photographing direction by driving optical image stabilization (OIS) devices or lenses to ensure that subsequent images are continuous with the first image within a threshold value, using image comparison units to determine similarity and continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If panorama shooting is performed using a general digital camera with manual alignment, then the device complexity is low, but the manufacturing precision of image continuity is poor
Solution Approach 1:
The patent introduces a handshake correction module as an intermediary component that automatically adjusts the photographing direction between capturing the first and second images. This mediator handles the precise alignment task, freeing the user from manual alignment while achieving threshold-value continuity without requiring complex multi-component systems
Solution Approach 2:
The system performs self-correction by automatically detecting image continuity and driving the handshake correction module to adjust the photographing direction when needed. The apparatus serves itself by autonomously identifying and correcting alignment issues without external intervention, improving image continuity precision while keeping the operation simple
2Reliability
If the user manually aligns images for panorama shooting, then the ease of operation is high, but the reliability of continuous image capture is low
Solution Approach 1:
The system implements feedback by comparing the captured second image with the first image to determine continuity within the threshold value. Based on this feedback, the control unit automatically drives the handshake correction module to adjust the photographing direction if continuity is not achieved, thereby improving reliability while maintaining ease of operation through automated correction
3Manufacturing precision
If reshooting is performed when images are not continuous, then the manufacturing precision of panorama quality is improved, but the loss of time increases
Solution Approach 1:
The system performs preliminary action by proactively driving the handshake correction module to adjust the photographing direction before the second image is fully captured, based on preliminary comparison results. This prevents the need for complete reshooting by correcting alignment issues during the capture process, thereby improving panorama quality precision while reducing time loss

Implementation Method 1
The handshake correction module may include one of an optical image stabilization (OIS) imaging device, an OIS lens, and a variable vertical angle prism.
Implementation Method 2
The handshake correction module may include one of an optical image stabilization (OIS) imaging device, an OIS lens, and a variable vertical angle prism.

AI summary
A digital photographing apparatus includes a handshake correction module and a method of controlling the digital photographing apparatus. As a first image and a second image that is input by minutely adjusting a photographing direction from the first image are captured by using a pre-mounted handshake correction module, the second image that is accurately continuous from the first image may be obtained. As such, highly reliable panorama shooting may be enabled and an ultra-wide-angle image having a viewing angle greater than that of a currently mounted lens may be obtained without exchanging the currently mounted lens for an expensive lens used in wide-angle shooting.
