Portrait photographing method, device and camera equipment

Abstract

The invention discloses a portrait photographing method, device and photographing equipment. The method includes: when detecting that the current shooting scene is a backlit scene, extracting the portrait part in the current shooting scene based on the depth of field information of the current shooting scene; Shooting to obtain the first image; extracting the background part in the current shooting scene; obtaining the second exposure compensation of the background part, and shooting the current shooting scene according to the second exposure compensation to obtain the second image; The two images are fused to obtain a fused target image. The embodiment of the present invention achieves the purpose of automatic exposure of backlit portraits based on multi-frame fusion, and can make the portraits and background parts in the finally captured images achieve reasonable exposures, thereby achieving better visual effects and improving user experience.

Description

Technical field [0001] The present invention relates to the technical field of image processing, and in particular to a method, device and camera equipment for photographing portraits. Background technique [0002] With the popularization of digital cameras and various mobile terminals with shooting functions, shooting digital images has become commonplace in people's lives. When shooting, we often encounter situations where the target object must be backlit. [0003] In the related art, when taking pictures under backlight conditions, the current shooting scene is usually photographed by the traditional global automatic light metering method. However, after using this traditional global automatic metering method to expose photos, the portrait part often encounters the problem of underexposure and obviously dark, and the brightness of the background part is often too high, and there is a tendency to overexpose. For example, such as figure 1 As shown, under the influence of under-...

AI Technical Summary

Problems solved by technology

However, in the photos exposed by this traditional global automatic light metering method, the portrait part often encounters the problem of underexposure and obvious darkening, and at the same time, the brightness of the background part is often too high, and there is a tendency of overexposure

For example, if figure 1 As shown, under the influence of portrait underexposure and background overexposure, it is difficult to achieve satisfactory visual effects in photos, and the user experience becomes poor.
