Example

[0071] First embodiment

[0072] In order to solve the problem that the existing flash fill light has a large difference in the reflection of certain parts of the captured image, and the brightness of the picture taken by the flash is uneven, which affects the user experience, this embodiment provides an exposure shooting method. Such as image 3 As shown, image 3 The basic flowchart of the exposure shooting method provided in this embodiment, the exposure shooting method includes:

[0073] S301: Detect whether the terminal is currently shooting the subject in a preset scene, if yes, go to S302, if not, go to S301.

[0074] It can be understood that the terminal in this embodiment includes at least one flashlight, and the number, type, and location of the flashlight are not limited herein. When the user turns on the camera for shooting, it is detected whether the terminal is currently shooting the subject in the preset scene, which can be the front camera of the terminal shooting t...

Example

[0088] Second embodiment

[0089] In order to better understand the present invention, this embodiment uses a more specific example for description. It is assumed that the user uses the rear camera of the terminal for shooting, such as Picture 9 As shown, Picture 9 This is a flowchart of the exposure shooting method provided by the second embodiment of the present invention, and the exposure shooting method includes:

[0090] S901: Detect whether the terminal is currently shooting a portrait in a preset scene, if yes, go to S902, if not, go to S901.

[0091] In this embodiment, the detection of whether the terminal is currently photographing a portrait in a backlit scene or a night scene is taken as an example for description. The portrait includes a portrait facial area, and the portrait facial area refers to a facial area including eyes, nose, and mouth of the portrait.

[0092] S902. Turn on the flash to determine whether the area of ​​the face area of ​​the portrait is greater th...

Example

[0105] The third embodiment

[0106] This embodiment also provides a terminal, see Picture 10 As shown, it also includes a processor 1001, a memory 1002, and a communication bus 1003. It can be understood that the terminal in this embodiment includes a flash and a camera; where:

[0107] The communication bus 1003 is used to implement connection and communication between the processor 1001 and the memory 1002;

Abstract

The invention discloses exposure photographing methods, terminals and a computer readable memory medium. A method comprises the steps of detecting whether a terminal currently photographs a photographing object in a preset scene or not; switching on a flash lamp if the terminal currently photographs the photographing object in the preset scene, and carrying out exposure photographing on a first preset area to obtain a first photographed image when the flash lamp carries out preflashing; carrying out the exposure photographing on a second preset area to obtain a second photographed image when the flash lamp carries out main flashing; and fusing the first photographed image and the second photographed image to obtain a target photographed image. The problem that brightness of images photographed through utilization of the flash lamp is nonuniform and user experience is influenced resulting from the fact that relatively great difference exists in reflected light of certain parts of the photographed images due to light supplement of the flash lamp is solved. The invention also discloses the terminals and the computer readable memory medium. Through application of the scheme, when the exposure photographing is carried out, quality of the photographed image is improved, and experience and degree of satisfaction of a user are ensured.

Description

technical field [0001] The present invention relates to the technical field of photographing, and more specifically, to an exposure photographing method, a terminal, and a computer-readable storage medium. Background technique [0002] With the development of photosensitive devices of various terminal cameras, the photo effect under dark light can more and more reflect the technical advantages of photosensitive devices. As an important supplementary light module for taking pictures in low light, the flash is becoming more and more important. However, there is a large difference in the reflection of some parts of the captured image due to the fill light of the flash, and it is difficult to make the exposure of some parts just right when taking pictures: for example, if the brightness of the near scene in the shooting picture is normal, the distant scene will appear too dark , and if the brightness of the distant view is normal, the near view will be overexposed, which will e...
