Image Loading Method for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing image loading methods in mobile terminal devices often result in a black screen issue before an image is displayed on the image editing interface, affecting user experience.
Innovation Solution
A method that involves obtaining a thumbnail of the target image upon selection, preloading it in memory, and rendering it on a target display control within the image editing interface using a lightweight renderer. After the image editing interface is initialized, the full image is decoded and re-rendered on the target display control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image editing interface is initialized completely before displaying the image, then the image can be displayed correctly, but the interface takes too long to load causing a black screen
Solution Approach 1:
The patent applies preliminary action by preloading the image data into memory before the image editing interface is fully initialized. The image is decoded and stored in advance, so when the interface becomes ready, the image is already prepared for display, eliminating the black screen issue while reducing loading time.
Solution Approach 2:
The patent segments the image loading process into distinct phases: thumbnail display phase (using a lightweight renderer) and full image display phase (using the complete image editing interface). This segmentation allows the interface to start with minimal requirements and progressively load more functionality, resolving the contradiction between reliability and loading time.
2Loss of time
If a lightweight renderer is used to display the thumbnail, then the interface loads faster, but the image quality may be reduced
Solution Approach 1:
The patent applies dynamics by making the renderer adaptive - starting with a lightweight renderer for thumbnail display and automatically switching to the full image editing interface renderer when the user needs to view the complete image. This dynamic transition resolves the contradiction by providing fast loading initially, then upgrading to high quality when needed.
Solution Approach 2:
The patent uses a thumbnail copy of the image for initial display instead of the full-resolution image. This copy allows fast loading and display while maintaining sufficient visual information for the thumbnail view, resolving the contradiction between loading speed and image quality by providing an acceptable approximation for the initial state.

AI summary
Embodiments of the disclosure provide a method, apparatus, an electronic device, a storage medium, a computer program product and a computer program of image loading. A thumbnail of the target image is obtained in response to a selection operation for a target image, the thumbnail of the target image being preloaded in a memory; the thumbnail is rendered on a preloaded target display control, where the target display control is provided in an image editing interface, and the target display control is used for being called by the image editing interface so as to display an image loaded on the image editing interface; and an image to be edited is obtained by decoding the target image, and after an initialization of the image editing interface is completed, the image to be edited is re-rendered on the target display control through the image editing interface.
