Image Cropping Apparatus for Multi-Object Framing and Diversity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image cropping techniques fail to effectively handle images with multiple objects, often resulting in undesired cropping or the generation of similar crop images, as they do not adequately account for the arrangement and number of objects within the image.
Innovation Solution
An image processing apparatus that specifies object regions, sets multiple crop region candidates based on object characteristics, evaluates these candidates using various parameters, and selects the most suitable regions to ensure preferred framing and diversity in cropped images, preventing similar images from being generated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a crop position is determined such that one object is located at a predetermined position in a cropped image, then the preferred framing of a single object is achieved, but when multiple objects exist in the image, some objects may be excluded from the preferred framing
Solution Approach 1:
The patent segments the image processing task by evaluating multiple crop region candidates separately and selecting the most appropriate one based on object positions. Instead of using a single fixed crop position, the system divides the image into multiple potential crop regions and evaluates each one to determine which best satisfies the preferred framing conditions while including relevant objects.
2Productivity
If crop images are generated in accordance with a plurality of crop regions that have been set as described in conventional techniques, then multiple crop images can be produced, but a plurality of similar crop images may be generated
Solution Approach 1:
The patent changes parameters such as crop region position, size, and aspect ratio to generate diverse crop images. By varying these parameters across different candidates and selecting based on evaluation results, the system produces multiple crop images with different characteristics rather than similar repetitions, thereby improving image diversity while maintaining productivity.

AI summary
Provided is an image processing apparatus that determines crop positions for an image including a plurality of objects in a preferred manner. This image processing apparatus specifies object regions from the image, and sets a plurality of crop region candidates for each of the specified object regions. The image processing apparatus selects a predetermined number of crop regions from among the plurality of crop region candidates based on evaluation values obtained for the plurality of crop region candidates and on similarities among the plurality of crop region candidates.
