[0030] Such as figure 1 As shown, the first embodiment of the present invention provides a method for taking pictures, which is applied to a mobile terminal with a first camera and a second camera, and the method for taking pictures includes:

[0031] Step 101, when a mobile terminal user's activation request of a camera function is received, the first camera and the second camera are activated.

[0032] In this step, the mobile terminal includes two cameras, namely a first camera and a second camera. It should be noted that the first camera and the second camera are arranged adjacent to each other, and the images captured by the first camera and the second camera can be generally considered to be the same image; when the user inputs a start request, the first camera and the second camera The two cameras are powered on at the same time.

[0033] Step 102, controlling the first camera to capture images according to a first preset image size, and displaying the images captured...

Abstract

The invention provides a photographing method and a mobile terminal. The photographing method comprises the steps of starting a first camera and a second camera; controlling the first camera to collect images, displaying the images in a photographing preview interface in real time, and moreover, controlling the second camera to collect images and caching the images in real time; obtaining target photographing parameters input by a mobile terminal user at a first preset moment; controlling the second camera to collect images according to the target photographing parameters and caching the images in real time; and generating a picture by one image cached by the second camera according to the target photographing parameters at a second preset moment and storing the picture when a photographing instruction input by the mobile terminal user is received at the second preset moment. According to the method and the mobile terminal, the first camera outputs the images for preview according to a first preset size; the second camera is used for photographing; the power-on/power-off time of a single camera is saved; the photographing speed in a professional mode is improved; moreover, the preview is unnecessarily stopped in the photographing process; and the brightness and user experience of previewing the images are not influenced.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a photographing method and a mobile terminal. Background technique [0002] At present, the photo taking process in professional mode (manually setting the sensitivity ISO or exposure time, exposure value EV, focal length, white balance, etc.) is generally as follows: use non-zero-second snapshot ZSL to take pictures, and use 1 / 4 when previewing The sensor size of the sensor is output, the user sets the shutter time and ISO, and it will not take effect during the preview. When clicking to take a photo, power on and off the sensor again, let the sensor output a full-size image, and set the shutter time and ISO to the sensor In the register, after capturing the photographed image, power on and off the sensor again, let the sensor output at 1 / 4 the size of the sensor, and restart the preview. The process of taking pictures in professional mode takes too long, which affects...
