Embodiment 1

[0053] This embodiment will be described from the perspective of an image acquisition device. The image acquisition device may be integrated into a terminal and other devices. The terminal may include a mobile phone, a tablet computer, a mobile computer, and a wearable smart mobile device.

[0054] An image acquisition method, comprising: when a terminal starts a front camera process, detecting the ambient light brightness of the terminal, adjusting the screen brightness of the terminal, so that the ambient light brightness reaches the brightness required for preset shooting, and the brightness required for the shooting is Under brightness, detect the ambient light color temperature of the terminal, determine the color of the supplementary light according to the color temperature of the ambient light, and project light with the color of the supplementary light to the subject through the screen of the terminal, and then pass the front camera process to the subject. Perform image...

Embodiment 2

[0113] According to the method described in Embodiment 1, an example will be given below for further detailed description.

[0114] In this embodiment, it will be described by taking that the image capture device is specifically integrated in a terminal, and that the photographed object is a human face as an example.

[0115] Such as Figure 2a As shown, an image acquisition method, the specific process can be as follows:

[0116] 201. When starting a front camera process, the terminal detects ambient light brightness of the terminal.

[0117] For example, when the user enters the camera mode and turns on the front camera, the front camera process can be invoked, and then the ambient light brightness of the terminal can be detected; or, when the user enters the video recording mode and the front camera is turned on , call the front-facing camera process, and then detect the ambient light brightness of the terminal, and so on.

[0118] Among them, there are many ways to dete...

Embodiment 3

[0163] In order to better implement the above method, an embodiment of the present invention also provides an image acquisition device, which can be integrated into a terminal and other equipment. The terminal can include a mobile phone, a tablet computer, a mobile computer, and a wearable smart mobile equipment etc.

[0164] For example, if Figure 3a As shown, the image acquisition device may include a brightness detection unit 301, a brightness adjustment unit 302, a color temperature detection unit 303, a color temperature adjustment unit 304, and an acquisition unit 305, as follows:

[0165] (1) Brightness detection unit 301;

[0166] The brightness detection unit 301 is configured to detect the ambient light brightness of the terminal when the terminal starts the front camera process.

[0167] There are many ways to detect the ambient light brightness of the terminal. For example, the brightness detection unit 301 can receive the light monitoring information carrying t...

Abstract

The embodiment of the invention discloses an image collection method and device and a storage medium. According to the embodiment of the invention, when a terminal starts a preposed camera, the environment light brightness and environment light color temperature are detected so as to adjust the screen brightness of the terminal, and the light with the supplementary light color is projected to a photographed object through a screen, thereby enabling the environment light brightness to reach the brightness required by preset photographing. The color temperature can be balanced, so as to reduce the noise points and color deviation, to achieve the better collection of the images of the photographed object, and to improve the image quality.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an image acquisition method, device and storage medium. Background technique [0002] With the popularization and diversification of functions of smart mobile terminals (referred to as terminals), more and more users like to use terminals for shooting. However, since the cameras of most existing terminals are not equipped If it is relatively dark, the captured image will have problems of excessive noise and underexposure. Therefore, how to improve the quality of shooting in a dim environment has become one of the issues that people have paid attention to in recent years. [0003] In order to solve the above-mentioned problems, the prior art proposes a solution of increasing the brightness of the screen to realize the supplementary light effect. Specifically, when the user turns on the camera, obtain the ambient light brightness during the current shooting, determi...
