Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current star trail shooting methods result in dull background images, failing to meet diverse demands and thus deteriorating the shooting experience.

Innovation Solution

An image composition method where a preset image is set as a background, and the trail image of a moving object is composited with it at preset intervals to generate a target image, with adjustments for luminance and transparency to enhance image quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a preset image is used as a shooting background image, then the shooting experience is improved and diverse demands are met, but the background image becomes dull and lacks visual appeal

Engineering Contradiction:

Improvediverse demands for shooting background imagesVSAvoidvisual appeal of background image

Core Design Contradiction:

Adaptability or versatilityVSIllumination intensity

Solution Approach 1:

The patent combines the preset background image with the trail image of the moving object through image compositing. The processing module composites the shot current trail image with the background image to generate a target image, merging two separate images to create a visually appealing result that satisfies diverse shooting background demands while maintaining aesthetic quality.

Inventive Principle:

Principle #5Merging (Combining)

2Illumination intensity

If the luminance value of the background image is adjusted to improve composite image quality, then the visual appeal is enhanced, but the original luminance information is lost

Engineering Contradiction:

Improvevisual appeal of composite imageVSAvoidoriginal luminance information of background image

Core Design Contradiction:

Illumination intensityVSLoss of information

Solution Approach 1:

The processing module adjusts the luminance value of the background image before compositing it with the trail image. By performing the luminance adjustment in advance, the system enhances the visual appeal of the composite image while managing the trade-off of losing original luminance information, as the adjustment is part of the image preparation process before final composition.

Inventive Principle:

Principle #10Preliminary action

3Illumination intensity

If transparency of the background image or trail image is adjusted to enhance composite image quality, then visual appeal is improved, but control complexity increases

Engineering Contradiction:

Improvevisual appeal of composite imageVSAvoidcomplexity of image processing control

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The processing module adjusts the transparency parameter of either the background image or the trail image to generate the target image. By changing the transparency parameter, the system enhances the visual appeal of the composite image, allowing for flexible control over the blending effect while managing the complexity through parameter-based adjustments rather than complex processing algorithms.

Inventive Principle:

AI summary

A method, a device and a computer storage medium for image synthesis. The method for image synthesis includes: getting a default image, setting the default image to the background image of shooting; shooting the trajectory of moving objects; at the end of the shooting, synthesizing images of the trajectory of moving objects shot currently and the background image to generate a target image.
