Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing smartphones lack a front-facing panorama shooting mode, making it difficult for users to capture panoramic images that include both themselves and their surroundings, resulting in reduced shooting effectiveness.

Innovation Solution

A method and terminal for acquiring a panoramic image by shooting a first image, determining and displaying move guiding information to instruct the user on terminal movement, and seamlessly splicing subsequent images to create a panoramic image with the first image at the center, ensuring consistent shooting parameters and highlighting the central position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If a rear-facing panorama shooting mode is used to shoot multiple photos and splice them into an image with a larger visual angle, then the visual angle of the panoramic image is improved, but the central position (person) cannot be highlighted and the shooting effect deteriorates

Engineering Contradiction:

Improvevisual angleVSAvoidshooting effect

Core Design Contradiction:

Area of moving objectVSEase of manufacture

Solution Approach 1:

The patent inverts the conventional panorama shooting sequence by capturing the central image first, then moving to capture surrounding images. This inversion ensures the person remains at the center of the final panoramic image, solving the problem of the central position not being highlighted while maintaining a large visual angle.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent performs preliminary action by capturing the central image containing the person before moving to capture other images. This preliminary capture of the central position ensures that the person is properly positioned and highlighted in the final panoramic image, improving the overall shooting effect.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If the terminal moves in only one direction during shooting to obtain a photo with a large visual angle, then the shooting operation is simplified, but the scene on only one side of the person can be shot and the shooting effect deteriorates

Engineering Contradiction:

Improveshooting operationVSAvoidscene coverage

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The patent segments the panorama shooting process into multiple directional movements: first moving in one direction to capture images, then returning to the central position, and finally moving in the opposite direction. This segmentation allows comprehensive scene coverage while maintaining simple operational guidance for the user.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs periodic action by having the terminal move forward to capture images, then return to the central position, and repeat the process in the opposite direction. This periodic movement pattern ensures complete scene coverage while keeping the operation simple and systematic.

Inventive Principle:

Principle #19Periodic action

3Measurement precision

If shooting is started from a person, then the person can be captured, but the scene on only one side of the person can be shot and the shooting effect deteriorates

Engineering Contradiction:

Improveperson positioningVSAvoidscene coverage

Core Design Contradiction:

Measurement precisionVSArea of stationary object

Solution Approach 1:

The patent inverts the conventional approach by capturing the central image containing the person first, then systematically capturing images in both directions from the center. This ensures both accurate person positioning and comprehensive scene coverage in the final panoramic image.

Inventive Principle:

Principle #13The other way round (Inversion)

4Area of stationary object

If shooting is started from a scene, then the background can be captured, but the person cannot be highlighted and the shooting effect deteriorates

Engineering Contradiction:

Improvescene coverageVSAvoidperson highlighting

Core Design Contradiction:

Area of stationary objectVSMeasurement precision

Solution Approach 1:

The patent performs preliminary action by capturing the central image containing the person before capturing the surrounding scene images. This ensures the person is properly positioned and highlighted in the final panoramic image while maintaining comprehensive scene coverage.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method includes: after a panorama shooting instruction triggered by a user is acquired, shooting a first image, and acquiring a shooting parameter of the first image; determining move guiding information according to a preset move guiding policy, and displaying the move guiding information on a terminal, so as to instruct the user to move the terminal according to the move guiding information; shooting a preset quantity of images according to the shooting parameter of the first image after it is detected that the terminal moves, where the preset quantity of images are background images on both the left and right sides of a background corresponding to the first image; and performing, by using the first image as a center and by using a preset splicing scheme, seamless splicing on the first image and the preset quantity of images, to obtain a panoramic image.
