Embodiment Construction

[0059] The photo preview method provided in this application can be applied to any terminal device with a camera function, including but not limited to: mobile phones, smart screens, digital cameras, tablet computers or notebook computers. The drawings in this application all take mobile phones as an example to illustrate the implementation process of the preview provided by this application.

[0060] figure 1 For the application scenario diagram provided for this application, see figure 1 As shown, when the user triggers to turn on the camera, the terminal device will jump to the photo preview interface, and the terminal device will display the image collected by the camera on the photo preview interface in real time for the user to view. The image displayed in real time on the photo preview interface It can be called a preview image, which can provide the posture of the scene and the subject, so that the user can refer to the preview image to adjust the shooting angle and e...

Abstract

The invention provides a photographing preview method, electronic equipment and a storage medium, and the method comprises the steps: determining a first exposure parameter value corresponding to a current photographing scene according to an environment parameter value in the current photographing scene and a first mapping relation; the first exposure parameter value is adjusted according to a first difference of a first preview image and a first real shot image in a current shooting scene on a first parameter, a second exposure parameter value is obtained, and the first parameter comprises at least one of a brightness parameter or a dynamic range parameter; the camera collects a first image according to the second exposure parameter value; and processing the first image to obtain a second preview image. The display effect consistency of the preview image and the real shot image is improved, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of terminals, and in particular to a method for taking pictures and previewing, electronic equipment and storage media. Background technique [0002] When the user uses the terminal device to take pictures, after triggering the camera to be turned on, the terminal device will jump to the photo preview interface, and the terminal device will display the images collected by the camera on the photo preview interface in real time for the user to view. When the user is ready to shoot, the camera is triggered, and the terminal device then uses multi-frame fusion technology to obtain the real shot image. However, the preview image displayed on the photo preview interface adopts a single-frame scheme, which cannot take into account both bright areas and dark areas at the same time, resulting in inconsistent display effects between the preview image and the real image that the user sees on the terminal devi...
