Photographing Workflow for Rapid Preview Before High-Resolution Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-resolution photos on electronic devices take a long time to process, leading to delayed image preview and a suboptimal user experience due to the processing speed limitations of the CPU.
Innovation Solution
Generate a low-resolution first image immediately after a photographing input and a high-resolution second image over time, displaying the first image if a user input is received before the second image is complete, and replacing it with the second image once ready.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a high-resolution photo is processed to increase pixel count, then photo quality is improved, but processing time increases leading to delayed image preview
Solution Approach 1:
The patent segments the image processing into two distinct stages: first generating a low-resolution preview image for immediate display, then generating a high-resolution final image for quality output. This segmentation allows the system to provide quick feedback to users while maintaining the option for high-quality processing, thereby resolving the contradiction between processing speed and image quality.
Solution Approach 2:
The system performs preliminary processing by first creating a low-resolution preview image before the user completes their photographing action. This preliminary action provides immediate visual feedback to the user, reducing the perceived waiting time, while the high-resolution processing is performed subsequently without delaying the initial preview.
2Measurement precision
If the CPU processes high-resolution photos, then image quality is improved, but processing speed is reduced due to CPU limitations
Solution Approach 1:
The processing task is segmented into two parts: a quick low-resolution processing path and a comprehensive high-resolution processing path. The system uses this segmentation to provide immediate feedback through low-resolution processing while maintaining the capability for high-quality processing, thus balancing productivity and quality without being constrained by CPU speed limitations.
Solution Approach 2:
The system applies partial processing (low-resolution processing) when immediate feedback is needed, and reserves full processing (high-resolution processing) for when quality is the priority. This partial action approach allows the system to overcome CPU speed limitations by not always requiring full processing power, thereby improving overall productivity while maintaining quality when necessary.

AI summary
A photographing method includes: receiving a photographing input on a target object; in response to the photographing input, generating a first image within a period from a time when receiving the photographing input to a first time and generating a second image within a period from the time when receiving the photographing input to a second time; and in a case that a second input by a user is received before the second time, displaying the first image in response to the second input, and displaying the second image after the second time. Pixels of the first image are fewer than pixels of the second image; and the second time is greater than the first time.
