Hand Shake Detection UI for Photographing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current photographing apparatuses face challenges in effectively detecting and displaying hand shake during image capture due to the limited size of liquid crystal display screens, making it difficult to assess image quality and decide on retakes.
Innovation Solution
A User Interface (UI) providing method that calculates hand shake values by comparing captured images with pre-capture images, displaying these values alongside the captured image, and optionally adjusting brightness and color, with the option to store or delete images based on these values, using a control unit within the photographing apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the LCD screen size is increased to properly detect hand shake from captured images, then the detection capability is improved, but the device complexity and portability are worsened
Solution Approach 1:
The patent transitions from spatial dimension (larger LCD screen) to temporal dimension (comparing multiple images taken at different times). By comparing a captured image with a pre-capture image, the system can detect hand shake without requiring a larger display screen, thus resolving the contradiction between detection capability and device complexity.
Solution Approach 2:
The patent introduces an image comparison mechanism as an intermediary between the captured image and the user's perception. Instead of directly displaying the hand shake effect on a large screen, the system uses image processing to calculate and display hand shake values, serving as a mediator that enables accurate detection without requiring increased screen size.
2Loss of information
If image processing complexity is increased to calculate and display hand shake values, then the information accuracy is improved, but the processing time is worsened
Solution Approach 1:
The patent performs preliminary action by capturing a pre-capture image before the actual photographing moment. This pre-capture image serves as a reference for subsequent hand shake detection, allowing the system to quickly calculate hand shake values by comparing with the pre-existing reference image rather than performing complex analysis from scratch.
Solution Approach 2:
The patent applies partial action by focusing image comparison only on specific regions or using simplified comparison algorithms. Instead of processing the entire image with full complexity, the system calculates hand shake values by comparing key features or regions, reducing processing time while maintaining sufficient accuracy for hand shake detection.

AI summary
A User Interface (UI) providing method and a photographing apparatus using the UI providing method are provided. The UI providing method includes capturing an image, calculating a “hand shake” value of the captured image by comparing the captured image with a pre-capture image corresponding to the captured image, and displaying a UI corresponding to the calculated “hand shake” value of the captured image along with the captured image. A user can decide whether to delete or edit a captured image based on “hand shake” information relating to the captured image.
