Adaptive Image Cropping for Blank-Free Screen Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face issues with blank spaces when switching between landscape and portrait modes due to resolution differences, leading to suboptimal display of images.
Innovation Solution
An electronic device that identifies screen mode changes, detects objects within images, generates candidate images by cropping regions, and selects a second image to eliminate blanks, adjusting size and resolution for optimal display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device displays an image in a changed screen display mode without processing, then the display mode change is simple and fast, but blank spaces appear on the screen due to resolution differences
Solution Approach 1:
The patent segments the original image into multiple candidate images by cropping different regions containing detected objects. This segmentation allows the system to select the most appropriate cropped image that fits the new display mode without blanks, thereby improving screen usage area while adapting to different display modes.
Solution Approach 2:
The patent changes the parameters of the displayed image by cropping regions containing detected objects to generate candidate images with different dimensions and aspect ratios. This parameter transformation enables the image to adapt to the new screen display mode and eliminate blank spaces caused by resolution differences.
2Area of stationary object
If the electronic device crops and processes the image to eliminate blanks, then screen usage area is maximized, but the processing time and computational complexity increase
Solution Approach 1:
The patent performs preliminary object detection on the original image before the display mode change occurs. By pre-identifying objects and their locations, the system prepares candidate crop regions in advance, reducing the processing time required when the display mode actually changes and needs to eliminate blanks.
Solution Approach 2:
The system automatically detects objects, generates candidate images, and selects the most appropriate one without requiring user intervention. This self-service approach streamlines the processing workflow, reducing manual time investment while maximizing screen usage area through automated image adaptation.
3Manufacturing precision
If the electronic device detects objects and generates multiple candidate images, then the image quality and relevance to displayed content improve, but the device complexity and processing load increase
Solution Approach 1:
The patent extracts only the essential elements (objects) from the original image using object detection, and generates candidate images by cropping regions containing these extracted objects. This extraction approach improves image processing precision by focusing on relevant content while avoiding the need to process the entire original image, thereby reducing overall system complexity.
Solution Approach 2:
The object detection module serves multiple functions: it identifies objects for content relevance, determines crop regions for generating candidate images, and provides information for selecting the best fitted image. This multi-functionality improves image processing precision while reducing device complexity by consolidating multiple processing tasks into a single versatile module.

AI summary
A method, performed by an electronic device, includes identifying that a screen display mode of the electronic device currently displaying a first image is changed from a first display mode to a second display mode, the screen display mode being one of a landscape mode and a portrait mode, identifying whether a blank exists on a screen of the electronic device, when the first image is displayed in the second display mode, based on identifying the blank exists, detecting one or more objects from the first image, generating candidate images by cropping a region that includes one or more of the one or more objects, selecting a second image from the plurality of candidate images, and displaying the second image so that the blank does not exist on the screen of the electronic device in the second display mode.
