[0028] Such as figure 1 As shown, it is a flow chart of the first embodiment of the image processing method of the embodiment of the present invention. The following figure is combined with Figure 2 to Figure 5 The implementation process of the image processing method is described in detail.
[0029] An embodiment of the present invention provides an image processing method, including:
[0030] Step 101, acquire an original image captured in a long-exposure photographing mode.
[0031] In this step, the original image is a photo taken based on a long exposure of the mobile smart device. An exposure with a shutter time slower than 1 second can be called a long exposure, which is an exposure method with a slow shutter (long exposure time).
[0032] Based on the images taken with long exposure, the images of dynamically moving objects are blurred, while the images of static objects are clear.
[0033] For example, in crowded street corners, lively bazaars, sports competitio...

[0076] Such as Figure 6 As shown, it is a flow chart of an embodiment of a specific implementation process of the image processing method of the embodiment of the present invention. The specific implementation process of the image processing method will be described below in conjunction with the figure.
[0077] Step 201, the mobile terminal acquires an image captured by the user in the long-exposure photographing mode;
[0078] What needs to be explained here is that the exposure time of the common photographing mode is generally tens of milliseconds or even shorter, and the exposure time of the long-exposure photographing mode can reach 32 seconds in the prior art of the mobile terminal. Therefore, based on the image captured in the long-exposure photographing mode, the dynamic moving object in the image is imaged as a blurred image, and the static object is imaged as a clear image.
[0079] Step 202, divide the image evenly into a plurality of images whose pixels are M×N...

[0100] Such as Figure 7 As shown, it is a schematic diagram of the basic structure of a mobile terminal according to an embodiment of the present invention, and this figure is combined with Figure 8 Specifically, it is a mobile terminal based on the image processing method.
[0101] An embodiment of the present invention provides a mobile terminal, including:
[0102] The image acquiring module 301 is configured to acquire an original image captured in a long exposure photographing mode.
[0103]It should be noted that the original image is based on a photo taken by a mobile smart device with long exposure. Based on the images taken with long exposure, the images of dynamically moving objects are blurred, while the images of static objects are clear.
[0104] The algorithm calculation module 302 is configured to calculate sharpness values of images in multiple regions in the original image according to a preset algorithm.
[0105] It should be noted that the preset alg...
