Embodiment Construction

[0019] Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals designate the same or similar elements throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0020] The embodiment of the present application aims at the problems in related technologies that the dynamic range and overall brightness of the image captured in the portrait night scene are not only low, but the face brightening effect is poor, and the bright areas of the scene are prone to overexposure and brightness distortion, which affects the user experience. An image processing method is proposed.

[0021] In the image processing method provided by the embodiment of the present application, when the night scene shooting scene contains a huma...

Abstract

The present invention provides an image processing method and device. The method comprises the steps of: in a night-scene shooting mode, if it is detected that the current shaking degree of a camera module is larger than a first threshold value, detecting whether images collected by the camera module at present comprise faces or not; if yes, according to the current shaking degree of the camera module, determining standard sensitivity corresponding to each image to be collected; according to the illuminance of the current shooting camera, the standard sensitivity corresponding to each image tobe collected and a preset exposure compensation mode, determining the exposure duration corresponding to each image to be collected; and according to the standard sensitivity corresponding to each image to be collected and the exposure duration, collecting the plurality of images in order and performing combination processing so as to generate a target image. Therefore, the image processing method improves the whole dynamic range and a face brightening effect of the portrait night-scene shooting images, avoids that the scene bright area generates overexposure and brightness distortion and improves the user experience.

Description

technical field [0001] The present application relates to the field of imaging technology, and in particular to an image processing method, device, electronic equipment and storage medium. Background technique [0002] With the development of science and technology, smart mobile terminals (such as smart phones, tablet computers, etc.) are becoming more and more popular. Most smartphones and tablet computers have built-in cameras, and with the enhancement of mobile terminal processing capabilities and the development of camera technology, the performance of built-in cameras is becoming more and more powerful, and the quality of captured images is also getting higher and higher. Mobile terminals are now easy to operate and portable, and it has become a norm for people to take pictures with mobile terminals such as smart phones and tablet computers in daily life. [0003] While smart mobile terminals bring convenience to people's daily photography, people's requirements for th...
