Image Trimming Composition Switching for Edge Objects

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing image processing technologies fail to effectively set a composition for trimming images when the object is largely displayed or positioned at the edge of the image, limiting the automatic setting of image composition.

Innovation Solution

An image processing apparatus and method that sets a second trimming region with a different composition when the first trimming region exceeds the image range, allowing for automatic composition setting by adjusting the size and position of the trimming region, and potentially changing the composition type or aspect ratio.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a first trimming region is set based on a fixed composition rule, then the composition follows a standard aesthetic pattern, but the trimming region may exceed the image range when the object is largely displayed or positioned at the edge

Engineering Contradiction:

Improvecomposition setting coverageVSAvoid trimming region validity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements dynamic composition setting by switching between multiple composition types (first composition with initial trimming region, second composition with adjusted trimming region) based on whether the initial trimming region exceeds the image range. This dynamic adaptation ensures reliable composition setting for all object positions and sizes while maintaining aesthetic quality.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes composition parameters by defining different composition types with different trimming region calculation methods. When the first composition's trimming region exceeds the image range, the system switches to a second composition with modified parameters that ensure the trimming region remains within valid bounds while still achieving aesthetic composition.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If automatic composition setting is implemented with a single fixed method, then the process is simple and fast, but it fails to handle cases where objects are largely displayed or positioned at image edges

Engineering Contradiction:

Improveautomatic setting simplicityVSAvoidcomposition setting applicability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal automatic composition setting system that handles multiple scenarios by incorporating multiple composition types. The first composition handles standard cases, while the second composition handles edge cases where objects are largely displayed or positioned at image edges, making the system universally applicable to all photographing scenes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements feedback by checking whether the trimming region calculated from the first composition exceeds the image range. Based on this feedback, the system automatically determines whether to switch to the second composition, creating a self-adjusting automatic composition setting process that maintains simplicity while improving applicability.

Inventive Principle:

Principle #23Feedback

AI summary

An image processing apparatus to generate a trimming image from an input image. The apparatus including a central processing unit (CPU) programmed such that during operation, when a first trimming region in which an object included in an input image is arranged with a first composition is beyond a range of the input image, sets a second trimming region in which the object is arranged with a second composition. One of the first composition or the second composition is a three division composition and the other of the first composition or the second composition is a two division composition.
