Embodiment 1

[0053] refer to figure 1 , shows a flow chart of Embodiment 1 of a shooting method of the present invention, the method is applied to a mobile terminal, the mobile terminal includes an infrared lamp and a camera, and the method may specifically include the following steps:

[0054] Step 101, turn on the infrared lamp, and collect a preview image through the camera;

[0055] The embodiments of the present invention are applicable to mobile terminals with infrared lamps and cameras. The mobile terminal may include a mobile phone, a tablet computer, a notebook computer, a smart wearable device, a personal digital assistant, etc. The embodiment of the present invention does not limit the specific form of the mobile terminal. For ease of description, the embodiments of the present invention are described by taking a mobile phone as an example, and other application scenarios may be referred to for each other. The shooting in the embodiment of the present invention may specificall...

Embodiment 2

[0080] In the embodiment of the present invention, the mobile terminal can be set to have a normal photographing mode and a low-illuminance photographing mode. After the user opens the camera application in the mobile terminal, he can manually select the current photographing mode. When it is detected that the current ambient brightness value is low during the process, the LED flash can be turned on for supplementary light; if the user chooses the low-light photo mode, when the current ambient brightness value is detected to be low during the photographing process, the infrared light can be turned on for supplementary light , for a quiet and discreet photo mode.

[0081] When the user selects the low-illuminance photo mode, the mobile terminal can turn on the infrared light to supplement the light. In order to simplify the user's operation, the embodiment of the present invention can also detect the current ambient brightness value of the mobile terminal. If the ambient brightn...

Abstract

The embodiment of the invention provides a photographing method and a photographing device, applied to a mobile terminal comprising an infrared lamp and a camera. The method comprises the steps of opening the infrared lamp, and collecting a preview image via the camera; determining a light measurement area of the preview image, and computing an exposure brightness value according to the light measurement area; and adjusting luminous intensity of the infrared lamp according to the exposure brightness value and a preset target brightness value, and taking a photo via the camera. According to themethod and the device provided by the embodiment of the invention, the photographing effect of the mobile terminal under high and low light conditions can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a shooting method and device. Background technique [0002] With the continuous development of mobile terminal technology, users can use the mobile terminal to take photos, and users have higher and higher requirements for the shooting function of the mobile terminal. [0003] However, the shooting effect of mobile terminals under low-light conditions is still unsatisfactory. The photos taken are usually dark or noisy, and images cannot even be taken in a completely dark environment. Wherein, the low-illumination condition refers to an environment with low light intensity, such as a nighttime environment. [0004] At present, LED (Light Emitting Diode, light-emitting diode) flash can be used for light compensation to improve the shooting effect of mobile terminals under low-light conditions. However, some shooting scenes are not suitable for using flash, such as shooting wild ...
