Method and device for adjusting brightness of eye portion based on shooting identification

Abstract

The invention discloses a method and a device for adjusting brightness of an eye portion based on shooting identification. The device comprises an identification unit, a partitioning unit and an adjustment unit. The identification unit is used for obtaining an image to be shot and identifying the eye portion in the face portion in the image; the partitioning unit is used for partitioning the eye portion into at least two regions according to a preset strategy, obtaining a position coordinate section of each region, and obtaining a brightness value of the region corresponding to the coordinate section of the position based on the position coordinate section; and the adjustment unit is used for adjusting the brightness of the corresponding region according to the size comparison result of the brightness value and the preset brightness range in order to improve underexposure of the eye portion in the shot image. The method and the device for adjusting brightness of the eye portion based on shooting identification can perform region partition on the eye portion in the human face in the shot image, adjusts the brightness according to the brightness value of various regions, and improves the underexposure of the eye portion in the shot image.

Description

technical field [0001] The present invention relates to the technical field of photographing, in particular to a method and device for adjusting eye brightness based on photographing recognition. Background technique [0002] At present, when a camera of a terminal device is used to shoot a portrait or a face, due to the complex light conditions outside, it is very easy to produce underexposure in the face area. For example, if you use a flash in a dark environment, once the brightness or angle of the flash is not appropriate, it is very easy to cause underexposure of some areas of the face. In view of the above situation, the camera of the existing terminal equipment has a face automatic exposure function when shooting, that is, metering is performed according to the face part, so as to control the exposure degree of the sensor and achieve the purpose of moderate overall brightness of the face. However, this technology controls the exposure of the entire shooting screen, a...
