Figure photographing method and device and image pickup equipment

Abstract

The invention discloses a figure photographing method and device and image pickup equipment. The method includes: when detecting that a current shooting scene is a backlighting scene, extracting a figure part in the current shooting scene based on depth of field information of the current shooting scene; obtaining first exposure compensation of the figure part, and shooting the current shooting scene according to the first exposure compensation to obtain a first image; extracting a background part in the current shooting scene; obtaining second exposure compensation of the background part, and shooting the current shooting scene according to the second exposure compensation to obtain a second image; and performing fusion processing on the first image and the second image, so as to obtain a fused target image. The figure photographing method provided by the embodiment of the invention achieves the purpose of automatic exposure of a backlighting figure based on multiframe fusion, and can enable the figure and background part in the shot image that is finally obtained to realize reasonable exposure, thereby realizing a better visual effect, and improving user experience.

Description

technical field [0001] The present invention relates to the technical field of image processing, 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, taking digital images has become commonplace in people's lives. When shooting, it is often encountered that the target object must be backlit. [0003] In related technologies, when taking pictures under backlight conditions, a traditional global automatic light metering method is usually used to take pictures of the current shooting scene. 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, un...

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.
