Rotating Selection Frame for Image Cropping and Auto-Resizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image editors face issues with image rotation, where parts of the image are cut off or undesirably filled with white/gray space due to the fixed rectangular image frame, especially when rotating images at angles other than 90 degrees, leading to missed details and inefficient use of display space.
Innovation Solution
A selection rectangle frame is rotated over the image instead of rotating the image within a fixed frame, allowing dynamic resizing to maintain the frame within the image boundaries, enabling intuitive cropping and rotation operations while preventing unwanted space addition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the image is rotated within a fixed rectangular picture frame, then the rotation operation is simple to implement, but parts of the image are cropped or white/gray space is added beyond the original image dimensions
Solution Approach 1:
Instead of rotating the image within a fixed frame, the patent inverts the approach by keeping the image stationary and rotating the selection frame over the image. This inversion resolves the contradiction by allowing the frame to adapt to the rotated view while maintaining complete image visibility without cropping or adding unwanted space.
Solution Approach 2:
The patent applies dynamics by making the selection frame rotatable and resizable rather than fixed. The frame dynamically adjusts its orientation and dimensions to match the rotated perspective, ensuring the entire image remains visible while providing intuitive rotation control to users.
2Adaptability or versatility
If the selection frame is rotated at angles other than 90 degrees, then flexible rotation is achieved, but the frame either adds white/gray background space or crops the image due to rectangular matrix constraints
Solution Approach 1:
The selection frame is made dynamic by allowing it to rotate to any angle and automatically resize to maintain proper proportions. This dynamic behavior enables flexible rotation at any angle while the frame adapts its shape to prevent both cropping and addition of unwanted background space.
Solution Approach 2:
The patent changes the parameters of the selection frame by allowing rotation angle and frame dimensions to vary continuously. The frame's width, height, and orientation are adjusted as parameters to match the rotated perspective, enabling versatile rotation while maintaining image integrity without rectangular matrix constraints.
3Device complexity
If a fixed rectangular picture frame is used for image display, then the display structure is simple, but important parts or details of the image are missed when rotation is performed
Solution Approach 1:
The patent inverts the traditional approach by making the frame rotatable rather than the image. This allows the frame to adapt to the rotated view and maintain visibility of all image details while preserving a relatively simple display structure based on the selectable frame mechanism.

AI summary
A portable electronic device (200, 800), computer program product (862), and method of presenting image information on a display (208, 834) with combined cropping and rotation selection and auto-resizing of cropped portion of the displayed image. A processor (802) accepts a selection of a portion of a displayed image (502) by creating and displaying a selection rectangle frame (504, 704) over the displayed image based on detecting a first user gesture in connection with the displayed image. The processor determines a user request for rotation of the displayed selection rectangle frame based on detecting a second user gesture. The processor then rotates the selection rectangle frame on the displayed image and resizes the selection rectangle frame while maintaining it within the outer boundaries of the displayed image and while contemporaneously expanding the selection rectangle frame up to an original size of the selection rectangle frame created and displayed over the displayed image.
