[0026] Such as figure 1 As shown, the embodiment of the present invention provides a photographing method, which is applied to a mobile terminal, and the mobile terminal includes a first camera and a second camera with different light sensitivity. The photographing method specifically includes:

[0027] Step 101: Detect whether the environmental brightness value of the scene to be shot is within a preset brightness range.

[0028] Among them, the preset brightness range of the ambient brightness mentioned here refers to the range of ambient light brightness that can be imaged after the focus is successfully focused with a long focus time and a low success rate in the traditional focus mode. Specifically, the preset brightness range refers to the range of brightness values ​​in a darker environment (such as 1 Lux to 50 Lux). When the ambient brightness value is within the preset brightness range, it means that the current scene is a relatively dark environment. Such as night or a d...

[0037] The above first embodiment briefly introduces the photographing method of the present invention, and this embodiment will further describe it with reference to the drawings and specific application scenarios.

[0038] The photographing method of the present invention is applied to a mobile terminal, and the mobile terminal includes a first camera and a second camera with different light sensitivity. Specifically, the first camera is a black and white camera with high light sensitivity, and the second camera is a traditional color camera; the light intensity of the color camera is 50 Lux (lux), and the black and white camera is in a low light condition of 0.005 Lux Can also capture high-resolution image information. Among them, such as figure 2 As shown, the photographing method includes the following steps:

[0039] Step 201: Collect real-time environmental information of the scene to be shot through the light sensor.

[0040] The ambient light sensor can sense the light co...

[0061] The first embodiment and the second embodiment above respectively introduce the image processing methods in different scenarios in detail. The following will combine image 3 with Figure 4 The corresponding mobile terminal will be further introduced.

[0062] This embodiment provides a mobile terminal that includes a first camera and a second camera with different light sensitivity, which can detect whether the ambient brightness value of the scene to be shot is in the preset brightness range in the first and second embodiments Within; if it is detected that the ambient brightness value is within the preset brightness range, the first camera is controlled to focus on the scene to be photographed, and the obtained focus information is sent to the second camera; wherein the sensitivity of the first camera is higher than Sensitivity of the second camera; control the second camera to focus according to the focus information, after the second camera is focused, control the seco...

Abstract

The invention discloses a photographing method which is applied to a mobile terminal having a first camera and a second camera. The photographing method comprises the steps of: detecting whether an ambient brightness value of a scene to be photographed is within a preset brightness range; if so, controlling the first camera to perform focusing processing on the scene to be photographed, and transmitting the obtained focusing information to the second camera; controlling the second camera to perform focusing according to the focusing information; and controlling the second camera to acquiring first image information of the scene to be photographed after the second camera finishes focusing, wherein the photographic sensitivity of the first camera is higher than that of the second camera. According to the photographing method, the first camera with high photographic sensitivity is started for focusing under the specific brightness condition and sends focusing parameters to the second camera, so that the second camera can perform focusing and acquire images according to the focusing parameters, thereby solving the problem that clear pictures cannot be photographed due to low ambient brightness.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a photographing method and a mobile terminal. Background technique [0002] With the development of communication technology, mobile terminals have more and more entertainment functions. Among them, the camera function, as one of the core entertainment functions, has become an important aspect for users to consider mobile terminals. The current mainstream mobile phone cameras are basically equipped with an auto focus (AF, Auto focus) lens, which can focus quickly and accurately when the surrounding environment is sufficiently bright. However, in the case of poor brightness in the surrounding environment, there are problems of slow focus and inaccurate focus, which lead to the problems of long shooting time and poor shooting effect. Summary of the invention [0003] The embodiments of the present invention provide a photographing method and a mobile terminal to solve the...
