Solution Overview

Problem

Current electronic devices lack an advanced feature to effectively compose and present a series of images taken in burst mode or retrieved from videos, which limits the ability to showcase continuous actions of moving objects in a visually engaging manner.

Innovation Solution

An electronic device with an image input unit, image processing unit, and user interface unit that selects key images based on specific characteristics, combines portions of these images to generate a composite image, and allows user interaction to update and manipulate the composite image for presentation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a series of images are taken in burst mode or retrieved from video to record continuous actions, then the ability to capture moving objects is improved, but the capability to present these images in various ways is lacking

Engineering Contradiction:
Improvecontinuous action recordingVSAvoidimage presentation capability
Core Design Contradiction:
Duration of action of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent segments the series of images by selecting key images that represent different stages of continuous action. The image processing unit identifies and extracts specific portions from multiple images to compose a composite image that tells a visual story of the continuous action, transforming a static collection into a dynamic narrative sequence.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds a temporal dimension to image presentation by composing composite images that show progression of action across multiple time points. The user interface presents both individual key images and their composite arrangement, allowing users to view the series in chronological or thematic sequences, effectively adding time as a presentation dimension.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple images are processed to create composite representations, then the visual presentation capability is improved, but the complexity of image processing increases

Engineering Contradiction:
Improveimage composition capabilityVSAvoidimage processing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The image processing unit automatically performs key image selection and composite composition without requiring manual user intervention. The system autonomously analyzes the series of images, identifies important moments representing continuous action, and generates composite images, thereby reducing the perceived complexity for users while maintaining sophisticated processing capabilities.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-processes the series of images by identifying and selecting key images that capture essential moments of continuous action before final composite generation. This preliminary selection organizes the raw image data into meaningful segments, simplifying subsequent composite creation and reducing overall processing complexity.

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If key images are selected and portions are extracted to generate composite images, then the ability to represent different regions of the scene is improved, but the time required for image composition increases

Engineering Contradiction:
Improvescene region coverageVSAvoidimage composition time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The image processing unit extracts only the essential portions from key images that represent different regions of the scene. Rather than processing entire images, the system identifies and extracts specific segments containing important visual information, reducing processing time while maintaining comprehensive scene coverage across the composite image.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies different processing qualities to different regions of the composite image based on their importance. Key regions representing critical moments or areas of continuous action receive higher processing priority and detailed extraction, while less critical regions use simplified processing, optimizing the balance between information coverage and composition time.

Inventive Principle:
Principle #3Local quality

AI summary

An electronic device and an image composition method thereof are provided. The electronic device selects a plurality of key images from a plurality of images corresponding to a scene according to a first image characteristic, and selects at least two portions from the plurality of key images according to a second image characteristic. Each of the at least two portions corresponds to different regions of the scene. Then, the electronic device generates a composite image corresponding to the scene by combining the at least two portions and provide the composite image and at least two of the key images from which the at least two portions are selected to a user.
