Movable Effect Grid for Image Preview on Touch Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable handheld devices face challenges in efficiently previewing and comparing different image effects due to limited screen size and resolution, making it difficult for users to discern subtle effects and navigate through various filters.
Innovation Solution
A method and device that utilize a movable effect grid on the touch screen, divided into areas producing different effects, allowing users to interact with the image to generate preview images and select a final processed image based on preferred effects, with features like resizing and user-configurable grid patterns for enhanced comparison and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple filtered images are displayed side by side on a small touch screen, then users can compare different effects, but the image resolution is reduced making it difficult to discern subtle effects
Solution Approach 1:
The effect grid is divided into multiple areas, each applying a different filter effect to a corresponding portion of the original image. This segmentation allows multiple effects to be displayed simultaneously while maintaining the original image resolution in each segment, solving the contradiction between comparison capability and image quality.
2Volume of moving object
If the touch screen size is reduced to make the device portable and pocket-sized, then the device becomes more portable, but the ability to display multiple images for comparison is limited
Solution Approach 1:
Instead of displaying multiple complete images side by side (requiring large horizontal space), the patent overlays multiple filtered versions of the same image area simultaneously using the effect grid. This transforms the problem from a spatial arrangement issue to a layering/compositing solution, allowing full-resolution comparison on small screens.
3Measurement precision
If users switch among different filters one by one to experiment with effects, then each effect can be observed individually, but the process is time-consuming and tedious
Solution Approach 1:
The system pre-applies multiple different filters to create the effect grid overlay before the user makes a selection. This preliminary preparation allows users to compare multiple effects simultaneously without having to manually switch between filters, significantly reducing the time required for effect comparison while maintaining observation accuracy.

AI summary
The present disclosure proposes a method of previewing a processed image, a portable handheld electronic device using the same method, and a non-transitory storage medium which stores computer programs to execute the same method in a portable handheld electronic device. The method includes displaying on the touch screen an image, displaying on the touch screen a movable effect grid which is divided into a plurality of areas according to a predetermined pattern with each area producing a different effect, performing image processing between the image and the movable effect grid to generate a first preview image which has different effects in different areas defined by the predetermined pattern, and displaying the first preview image on the touch screen.
