Camera Thumbnail Pre-Generation for Faster Shooting Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for displaying thumbnails after a photo is taken by a terminal result in a long duration between the user triggering the shooting and the thumbnail being displayed, leading to a perceived slow shooting speed.
Innovation Solution
The method involves generating the thumbnail before the user lifts their hand after pressing the shooting control, shifting the thumbnail generation operation forward, allowing the display to occur only when the hand is lifted, thus reducing the overall duration.

Engineering Contradiction Analysis
1Speed
If the terminal performs thumbnail generation and display operations after the user presses and lifts the shooting control, then the shooting operation is completed, but the duration from pressing to displaying the thumbnail is long, resulting in slow perceived shooting speed
Solution Approach 1:
The terminal generates the first thumbnail in advance when the user presses the shooting control but does not lift the hand, before the shooting operation is officially completed. This preliminary action allows the thumbnail to be ready for immediate display when the user lifts the hand, significantly reducing the perceived shooting duration and improving shooting speed

AI summary
Embodiments of this application provide a method for displaying a thumbnail during shooting and an electronic device. In the method, a terminal generates a first thumbnail in a shooting interface of the terminal when a user presses a shooting control in the shooting interface but does not lift a hand, and the terminal displays the first thumbnail in a thumbnail display region of the shooting interface when the user lifts the hand.
