AI Technical Summary

Technical Problem

Existing photography methods face challenges in capturing precise moments due to human reaction delays and camera shutter lag, leading to misaligned timing between the user's intent and the actual capture, especially in fleeting scenes, and require significant memory storage for caching preview images to select the best frames.

Method used

A photography method that scores each preview frame, caches candidate frames within a defined time window, and replaces older cached frames to optimize storage, allowing for a broader selection of frames around the moment of capture, enhancing matching between the intended and captured images while conserving memory.

Benefits of technology

This method improves the alignment of user intent and captured images by extending the selection range around the capture moment, reducing memory usage and enhancing the quality of captured photos.

Abstract

The present application is applicable to the field of terminal technology, and provides a photographing method and an electronic device, which respectively determine corresponding candidate images from each group of preview images that fall into an observation time window in sequence, and after each candidate image of a group of preview images is determined, cache the currently determined candidate image in one of the preset first cache areas, and when all the first cache areas are occupied, replace the candidate image with the earliest cache time in all the first cache areas with the currently determined candidate image; when a photographing operation is detected, determine the image to be compared from the candidate images currently cached in the first cache area and the observation cache area, and determine the manually captured image corresponding to the photographing operation from the image to be compared and all preview images within a preset time length, which can not only improve the matching degree between the manually captured image and the user's expected image, but also save memory space.
