Camera Preview Zoom Switching with Software Image Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld mobile phone image stabilization is limited, leading to image shaking and blurring during photography, especially when magnified, affecting user experience.
Innovation Solution
An image photographing method that adjusts output modes based on zoom ratios and ambient lighting conditions using Binning, Remosaic, Quadra HDR, or Stagger HDR modes, combined with digital zoom and electric image stabilization, to optimize resolution and sharpness on the photo preview interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the photo preview interface magnifies the image by a certain ratio, then the image detail visibility is improved, but the image shake is also enlarged making it difficult to obtain a stable camera preview screen
Solution Approach 1:
The patent introduces an image stabilization algorithm as an intermediary processing step between image capture and display. This algorithm compensates for hand-shake effects by analyzing consecutive frames and adjusting the displayed image position, thereby stabilizing the preview screen while maintaining magnification capability.
Solution Approach 2:
The patent creates a stabilized copy of the original image for display purposes. By generating a corrected version of the image that compensates for shake while preserving the magnified view, the system allows users to see both high-detail magnified images and stable preview simultaneously.
2Ease of operation
If handheld image stabilization is used, then portability and ease of operation are improved, but image shaking and blurring cannot be completely avoided
Solution Approach 1:
The patent replaces or supplements mechanical image stabilization with software-based image stabilization algorithms. By using computational methods to analyze and correct hand-shake effects in the captured images, the system enhances stability without adding mechanical complexity, maintaining portability while improving reliability.

AI summary
Provided are an image photographing method, a device, a storage medium, and a program product. The method includes: displaying a first preview interface of a camera application, where the first preview interface includes a first preview image, the first preview image is obtained after processing a first image collected by a camera, the first preview image corresponds to a first zoom ratio, and the first image corresponds to a first output mode of the camera; receiving a first operation performed by a user; and displaying a second preview interface of the camera application in response to the first operation, where the second preview interface includes a second preview image, the second preview image is obtained after processing a second image collected by the camera, the second preview image corresponds to a second zoom ratio, and the second image corresponds to a second output mode of the camera. The second output mode is different from the first output mode, and the second zoom ratio is different from the first zoom ratio.
