Image Processing Device Viewpoint Inversion for Front Blur Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing techniques for changing the viewpoint of parallax images are not intuitive, making it difficult for users to understand how to move the blur region away from the subject, especially when front blurring occurs, as the movement direction of the viewpoint and the blur direction are opposite.
Innovation Solution
An image processing device that acquires and processes multiple viewpoint images, allowing users to designate a position on the image, detect the moving direction and amount of movement, and generate a new viewpoint image by moving the viewpoint in the opposite direction, thereby simplifying the process of correcting front blurring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the viewpoint is moved in one direction to correct front blurring, then the blur region moves away from the subject, but the user interface becomes confusing because the viewpoint movement direction is opposite to the intuitive expectation
Solution Approach 1:
The patent inverts the relationship between user input direction and actual viewpoint movement direction. When the user designates a position on the displayed image, the system calculates the viewpoint movement direction as opposite to the intuitive expectation, thereby moving the blur region in the direction the user intends. This inversion resolves the contradiction by making the blur region movement align with user intent while the viewpoint moves oppositely.
Solution Approach 2:
The patent introduces an intermediary calculation process that translates user designations into viewpoint movements. The system uses the designated position on the image as an intermediary reference point, calculating the required viewpoint movement to move the blur region away from the subject. This intermediary mechanism allows the system to achieve the desired effect (blur region movement) while managing the counterintuitive viewpoint movement.
2Measurement precision
If a complex user interface is used to precisely control viewpoint movement, then accurate correction is achieved, but the operation becomes difficult to understand
Solution Approach 1:
The patent implements a self-service mechanism where the system automatically calculates the appropriate viewpoint movement based on the user's simple position designation. Instead of requiring the user to understand and control viewpoint movement parameters directly, the system uses the designated position to automatically determine the movement方向和量, thereby achieving precise correction through simple operation.
Solution Approach 2:
The patent changes the operational parameter from direct viewpoint movement control to position designation on the image. By allowing users to designate positions on the displayed image rather than controlling viewpoint parameters directly, the system simplifies the operation while maintaining precision through automatic calculation of the required viewpoint changes based on the designated positions.

AI summary
An image processing device includes an imaging unit which captures an image of a subject, generates an image from a plurality of viewpoint images with different viewpoints, and displays the generated image on a display unit. A system control unit acquires a position designated using an operation unit by a user on a displayed image and detects a direction of a slide operation and an amount of movement from the designated position. An image processing unit acquires a plurality of pieces of viewpoint image data from the imaging unit and acquires distance information associated with a viewpoint image from a distance information acquisition unit. The image processing unit generates a viewpoint image if the viewpoint is moved in a direction opposite to the direction of the slide operation by the user on the basis of the plurality of viewpoint images.
