Problems solved by technology

[0003] However, due to the size limitation of terminals such as mobile phones, the apertures of the cameras equipped with them are very small, and it is impossible to set the shutter time (exposure time) very short while maintaining sufficient exposure
In this way, when the terminal takes pictures of moving objects, obvious ghosting and smearing usually occur, making the captured images very unclear and reducing image processing efficiency

Embodiment 1

[0062] Embodiment 1 of the present invention provides an image processing method, which is executed by a terminal, specifically by an image processing device installed in the terminal, such as figure 1 As shown, it specifically includes the following steps:

[0063] S11. Obtain the ambient brightness of the current photographing and the photographing moving speed of the target object.

[0064] In this step, the target object refers to one or more people, animals or scenery within the lens range of the image processing device. The photographing moving speed of the target object refers to the moving speed of the photographed target object relative to the image processing device. It should be noted that the image processing device may be used to acquire all images within the range of the lens, and of course, all the images include the image of the target object. Wherein, the image processing device may include components such as a camera, a light sensor, and an image processor....

The method includes the steps of obtaining current ambient brightness for photographing and photographing movement speed of a target object, determining an exposure parameter and a gain parameter according to the current ambient brightness for photographing and the movement speed of the target object, and processing the picture of the obtained target object according to the exposure parameter and the gain parameter. The method, the device and terminal can be used in data processing technology.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to an image processing method, device and terminal. Background technique [0002] For current terminals, such as mobile phones and tablet computers, etc., are equipped with cameras, users can use the terminals to take pictures anytime and anywhere. [0003] However, due to the size limitation of terminals such as mobile phones, the apertures of the cameras equipped with them are very small, and it is impossible to set the shutter time (exposure time) very short while maintaining sufficient exposure. In this way, when the terminal takes pictures of moving objects, obvious ghosting and smearing usually occur, making the captured images very unclear and reducing image processing efficiency. Contents of the invention [0004] Embodiments of the present invention provide an image processing method, device, and terminal, which can make a captured image clearer and effectively imp...
